Yūki Rito

Rito Yuuki is the main male protagonist of To Love-Ru and To Love-Ru Darkness. He is a normal 16 year old student of Sainan High, who has a big crush on Haruna Sairenji and, to an extent, Lala Satalin Deviluke. He attempted numerous times to confess to her but has met with failure each time. Rito used to be on the soccer team in junior high and was quite good, but quit because he was constantly helping his father with his mangaka duties, thus did not want to leave his little sister Mikan Yuuki alone in the house. Mikan comments he is very good at the most "useless little things", like crane and festival games (e.g. hoops, catching fish, squirt guns). Along with the numerous useless little things Rito is good at, he is also an accomplished florist, gardener and horticulturalist.

Rito's nature is borderline clumsy, where he always ends up molesting or groping the many girls in the series (unintentionally, of course). He is generally kind, thoughtful and has a lot of respect for women, though mostly by intention, and not so much by success. Due to his shyness around girls, he is very clumsy around women and has great difficulty maintaining his composure around any sort of stimulating situation. Even without interference from Lala's inventions, Oshizu's psychic powers, or Celine jumping into his face, Rito is on his own clumsy enough to trip over absolutely nothing, and possesses an extraordinary skill in accidentally reaching his hands or face into the breasts or other private parts of any girl within reach when he is falling.

It is only by accident that he encounters Lala, a troublesome character who at first pretends to show affectionate feelings for Rito at the beginning of the story. But despite his enduring feelings for Haruna, Rito shows signs of developing deeper affection towards Lala. As the story progresses, he starts to show affections for Lala, but is unsure if what he feels is actually love. This is shown again when he couldn't help but think about Lala, even though he was naked with Haruna. It is recently revealed that he is in love with Lala, but he is also in love with Haruna. In the end of the series, he confesses to Lala, but tells her he also loves another person (Haruna), yet she is happy on both parts. He is confused as polygamy is illegal in Japan, but Lala replied that once he is the king of the universe the laws of Earth no longer applies. Then, she forces him to go tell Haruna (strapping a jet pack to his back). Right before he was about to tell her, she moves out of the way, just like when he confessed to her very early in the series, leading him to state "I love you" to all of the female cast with the exception of Momo, Mikan, Golden Darkness, and Haruna herself.

Appearance
Rito has golden brown eyes and  orange-brown hair. In the original series the spikes on his hair were sharp and seemingly sticking out, but To-Love-Ru Darkness his hair seems to be a lot more neat and softer.

Personality
Rito is humble, caring, and a gentleman (in principle), and is willing to help out almost anyone when they need it, even if they say they don't want or ask for it. He is also courageous and persistent enough to risk his life to protect his friends well being, like when he protected Lala from her strong bodyguards or the hitman Black, saved Haruna from Ghi Bree and stood up to his deceptively monstrous form, and traveled to a dangerous planet to find a cure for Celine when she was sick. For these reasons, Lala stated that he's the most dependable person in the Universe, but lacks dependency towards himself. Rito would also help out those who dislike him, such as Yami, like when she was sick from over-using her powers and he carried her to Mikado's clinic. He has also shown his sympathy for her when he learned of her past, and expressed anger towards the organization that created and raised her to become a weapon.

Being a normal boy, though, he initially can also easily and somewhat frequently lose his temper and snap at people when annoyed by their actions or words, even when he doesn't mean to. At first, he has shown to be angry and upset with Lala quite often, since he does have to put up with a lot of her hijinks, and even punched Ren in the face for thoughtlessly ruining what could have been a moment between him and Haruna.

Through being a humble person, however, Rito can often have low self esteem about himself as opposed to his common thinking kindly about others. He rarely gives himself credit for his good deeds, tends to dwell on his mistakes more than anything when sad, hardly ever speaks up for or voices himself and, in general, doesn't do anything to truly stand up for himself.

His personality as a kind and loyal friend makes him quite charismatic, trustful, and enables him to sway and befriend other people, particularly girls. He managed to change Yui's belief that all boys are shameless, and helped her open up to a chance for love. He managed to comfort and cheer up Nana when she was deeply upset, which lived up to Lala's positive expectation of him. Girls tend to feel a certain "warmth" when close to him like a hug or so. In the beginning, Rito was quite shy and nervous when it comes to talking to girls, mainly Haruna (even when picturing her in a swimsuit), but being around Lala all the time has helped him overcome this problem and now is to have actual conversation with them but can still get a little nervous around them. And he was able to change the hearts of Yami and Mea, who were both cold and trained killers, and helped them open up to friendship; a trait which Nemesis has taken notice of. He is a very charismatic person, always trying to make people feel better and understand others' points of view and changing it to a more positive outlook.

Rito can be very persuasive, using his words to befriend and comfort others, even those who have a slight resentment towards him. Further more, by speaking his mind out about how he feels and standing up for others, he makes them feel touched and happy deep down  (mostly to girls). It is because of this ability that Nemesis initially became interested in him.

He also cares for plants and animals, as shown when he was the only one who didn't neglect to care for the school flowers, and when he rescued a cat from a tree, both of which persuaded Haruna and Yui that he is really a kind person. This proves that he cares deeply for all known life,  including those that are artificially made like Yami and Mea, and would hate anybody who would abuse them.

Even though Rito is very abhorrent to sex, erotic scenarios and nudity, he still, being a teenage human boy, can find himself fantasizing about other girls and even somewhat enjoying some of the situations he is put in, such as looking around at the girls in his classroom casually with Lala's X-ray glasses on.

Unfortunately, while girls appreciate and cherish his innocent nature, his innocence is arguably one of his worst traits. He rejects sex and pleasure so much that he's arguably scared, or at the very least quite nervous, of them, and he easily loses his composure around even slightly provocative situations. As a result, he has grown to become very clumsy and shy around women, often looking away (if he can) when faced with upfront, erotic situations. His own clumsiness does very little to help him escape perverted situations with other girls, and is often to blame for them. For these reasons, he is either regarded by other girls as an innocent boy and suitable love interest, or an insolent boy and pervert. There are certain girls who think that he is quite cute when he blushes nervously in front of them, and Momo especially finds a few of his facial expressions cute. However, despite being very disoriented and awkward when sexual content is put in front of him, it's arguable that this makes him a much more empathetic and genuine person. Although Rito is not a 'pervert' and would never do lewd things of his own will, he does tend to (unknowingly) do them when he is asleep next to someone (dreaming about food like marshmallows), most often with Momo and one time with his sister Mikan.

Rito can also be a very warmhearted, wise, sweet, hard-working and sensitive person on his own terms. He is seen helping old people cross the street with their groceries, helping people who are injured, accompanying lost children to help find their parents and crying at sad parts in movies in one episode, greatly establishing his basic nature. Generally, Rito is kind, hardworking, reliable, thoughtful and caring, but also immature and innocent to the point that's basically childish, though he makes up for it with his inability to give up on others for good reasons and his continuing will to help others even at the cost of his own well-being, big or small.

History
Before Rito met Lala, it was stated that Rito had difficulty talking to girls, which led to his lack of confidence and clumsiness around them. His only friend was Saruyama. However, because of Lala's friendliness, and Rito's growing relationship with Lala, all of Lala's girl friends became Rito's as well, especially Haruna Sairenji, whom Rito had a crush on and could not even talk to prior to Lala's "descent".

As a child, Rito would often go out and play football/soccer with other kids, but because his parents weren't always around, which would leave Mikan all alone at home. Feeling bad for her as any good family member would, Rito would stay in to look after her.

Rito has always assisted his father's work as a manga artist, and then would take Mikan to a shrine nearby to play. One time, during his fifth grade, while Yui was also at the shrine, Rito climbed a tree to help a cat who was stuck. This was the first time that Yui met Rito, although it was years later during a déjà vu that Yui remembered that the boy was, in fact, Rito. The cat that Rito saved from the tree was the same cat that Yui tried but couldn't save prior to Rito and Mikan's arrival at the shrine. She tried to ask some of the boys from her class to help her,  but they rejected her because they hated Yui's strictness as their class representative, and left to play games instead. Because of that, Yui had the impression that all boys are bad. However, due to Rito's bravery, Yui's perception of boys changed, and she realized that not all of them are bad. Rito isn't aware that Yui was the same girl he met at the shrine.

During Rito's eighth grade, Rito became classmates with Haruna Sairenji. It was stated that this was the last time that Haruna and Rito became classmates (prior to the start of the series). In the anime, Rito has been in love with her when she was the only one who believed he did not vandalize the plants in the school garden. Haruna stated that she first noticed him during a school competition, when their class was lagging behind the other classes in a race, and he never gave up, and ended up winning the race for his class and won the trophy. Haruna also noticed Rito's care for the plants in the school, and noticed that Rito would always refill the water in the flower vase while no one else cared, and concluded that he must be a kind person.

Powers and Abilities
As a human boy of the most ordinary kind, Rito has no superhuman abilities of any kind, and no other physical skills that truly impress other people. Among some of his minor talents are gardening, sports, and manga illustration, the latter skill he uses to assist his mangaka father. Haruna mentioned that he is good at archery and is a very fast runner, as he was able to outrun four people ahead of him and win the sports festival race for his class (To LOVE-Ru Chapter 32). It was mentioned that he was also good at soccer. As his sister described, he's only good at basically useless things, such as sports, festival games, and video games. However, when brave enough, he is capable of improvising these minor talents and make them useful, like when he used his soccer skills to distract Lala's bodyguards and help her escape. It's unknown how his archery skills are but he has show to sightly have a good aim, as seen when playing ring tossing and he's also good with a BB gun. His most significant physical skills, however, are often seen to comedic and perverted effect.

As far as physical skills go, Rito has good resilience to physical attacks; a very useful characteristic for a boy regularly harassed by troublesome characters around him. Even though he gets punched and hit continuously, he can be seen dodging life-threatening attacks, such as Zastin's sword attacks and Yami's bladed transformations, even when she was still serious about killing him. This is referred to later on when Rito is seen narrowly dodging multiple sword slashes by Rin Kujou when she is possessed by the demonic sword Bladix; Yami notes that due to avoiding her own attacks at him over the year, Rito's ability to dodge deadly attacks has increased to the point which an Earthling shouldn't be able to avoid, he has also gained  extremely great reflexes. Comically, Rito can also become a very effective weapon for Haruna when she panics in fear and blindly attacks whatever scares her, using whatever, or whoever (Rito) she can grab.



Ironically, despite being a generally innocent boy without perverted intentions, Rito appears to have perverted physical talents which he himself is not aware of. Nemesis complimented his "Technique" on pleasuring women when she ordered him to massage her. Momo believes the same thing about him when he fondles her in his sleep, which she greatly enjoys.

But above all else, Rito's most remarkable and infamous "skill" is his ability to accidentally grope and molest any girl within his reach when he falls. Rito is often a victim to a near endless stream of otherworldly mischief and chaos around him, such as Lala's inventions, Oshizu's psychic powers, or Celine's pollens. But even without such interferences throwing him around, Rito is already often clumsy enough around women to trip over minor obstacles or absolutely nothing, and when he does, he never fails to accidentally reach his hands or face into the breasts or other private parts of any girl in close proximity to him. In To LOVE-Ru Darkness, his clumsiness evolves to a surrealistic level, where he is able to precisely reach his hands into the clothing of the girls, or partially strip off their clothing, and even grab their breasts and pinch their nipples, all of which purely by accident. His clumsiness is even able to "defeat" stronger opponents, such as when he fell down and violated Nemesis' genitals, apparently catching her off guard, and when he predictably tripped and "defeated" Rin's attempt to dodge him, managing to glimpse and pull her panties. While his perverted clumsiness is not exactly a true skill which he would ever be proud of, it's nonetheless become his trademark characteristic, the frequency and coincidence of which are nothing less than extraordinary. Even Yami claimed that it has reached a level to be called an ability.

Hobbies and Interests
Rito has a wide variety of hobbies. When he was younger, he would often play soccer for fun and competition, but has since moved on, making it a side interest of his. Rito's also fairly in touch with playing video games and watching TV, typically Magical Kyoko and whatever Lala, Nana, Momo or Mikan have already put on. It's possible he may enjoy books, as suggested by going to the school library to get one on plants.

But as an average human boy, Rito is not particularly talented and does not really accel in most of his interests and hobbies besides the rather insignificant ones, such as video games and festival games. He is, however, highly accomplished and connected with horticulture, plant care and planting in general.

Relationships with Other Characters
As the the main character of To Love-Ru, he has relationships with several characters and has his ups and downs with a lot of them. Most of whom are females who are in love with him, others, however have shown slight interest in him and it's unknown whether they have feelings for him too. The female characters' impressions of him are quite polarizing, as some find him to be truly kindhearted and innocent but clumsy, while others find him as a misbehaving and shameless pervert. They either love him, hate him or both.

Lala Satalin Deviluke
At the beginning of the series, Rito was already having love troubles with his crush Haruna, and when Lala suddenly appeared to him, she only brought him much more trouble. But as the series progresses, he becomes very good friends with Lala, and even falls for her romantically. Rito even states that he feels uneasy when Lala is not around. Rito started out very shy, inexperienced and incompetent around women, even to the point of practically being scared of anything sexual, until being forced to get used to the troublesome and shameless Lala greatly helped him become more comfortable around Haruna and women in general.

A lot of times, Rito is willing to risk his well-being even his life for Lala. For example, when Black, a hit man, pointed a gun at Lala, Rito stood in front of Lala and refused to move away. It is because of all of his positive traits that she believes he is the most dependable person in the universe.

At the end of the original series, Rito confesses his love to Lala, while also telling her that he loves Haruna as well. Lala is ecstatic about this, however, noting that once their marriage is official, Earth laws will no longer matter, and he will be free to marry both Lala and Haruna. Rito is shocked by this, stating that Lala is "too open-minded" (Chapter 162).

At first, it appeared that Lala was quite childish regarding her love for a generally unreliable boy, but as the series progressed and Rito gradually matures and shows his kinder side, it would appear that Lala was somewhat right about him and truly did see something special in him. When Rito goes to comfort and give advice and encouragement to a heartbroken Nana, Lala notices that Nana has cheered up, and she states that it's as expected of Rito (To Love-Ru Darkness Chapter 21).

In To Love Ru Darkness, Rito still loves both Haruna and Lala. While his main objective is to confess his love to Haruna, he does show his love for Lala and keeps it in mind. As the series progresses, Rito considers Lala and Momo's Harem idea; however, he quickly shakes it off.

Overall, Rito developed a very maturing, connected relationship with Lala, going with her on errands, weekend activities, afterschool events and just hanging around the household. Though he can usually get irritated by accidents caused by her and/or her inventions, he still has an incredibly open mind to her personality, and great love for her caring, innocent child-like side (when it doesn't cause problems or stress), and is almost always open to strengthening their relationship further as a couple.

Lala had put aside her own love for Rito until he had finally confessed to Haruna, but with some encouragement from Momo, Lala began acting like her old clingy self to Rito and yet still acts childish. With help from Momo, she now approaches him in a more adult way, like coming to him in the bathtub and asking for a kiss. But because of the kind of pressure Rito has about the Harem plan and the situation with Nemesis, he rejects it, although Lala understands that he must be going through a lot of complicated things and insted kisses him on the cheek and tells him she will be waiting until he's ready.

Haruna Sairenji
Haruna has been the girl of Rito's affections since before the start of the series. She essentially represents the most normal and peaceful relationship Rito could have had among his love interests. In many ways, Haruna would have made the perfect girlfriend for Rito, as she is similarly shy and modest, understands and loves Rito's kind and gentle nature, is very patient and forgiving of Rito's perverted clumsiness, and has also harbored affectionate feelings for him. But because Rito was far too shy, incompetent and clumsy to successfully confess his love to her, he never found the romantic relationship that he long desired with her. Although Rito owes much to the bold and extroverted Lala for the friendship he now enjoys between himself, Lala and Haruna, he now has both Lala's growing place in his heart and Haruna's loyalty and friendship to Lala to add to his indecisiveness.

Rito greatly cares for Haruna while also loving her. He comforts her whenever she feels frightened or awkward, and will go to extraordinary lengths to ensure her happiness and safety. While not having a boyfriend/girlfriend relationship, he manages to get along very well with her, talking with her when he can summon the courage to do so and even appreciates her caring side to him and others around her.

Yui Kotegawa
Being a strict, high-strung and no-nonsense girl with little tolerance for unacceptable behavior and an impression that boys are generally shameless, it is no surprise that she often has a negative impression towards Rito, (claiming that he's even worse that the Principal). In addition, she is often a target of Rito's perverted clumsiness, being caught in many provocative situations with him, much to her dismay. Although she will likely never stop believing that boys are always shameless, with Rito being no exception, overtime, she comes to accept that Rito is different from most boys. As she gradually understands and appreciates Rito's kindness and accepts that Rito is still shameless but not a bad person, Yui warms up to him and grows to like him. Yui would prefer Rito to be more responsible for is own actions, as she mentioned that because his is so careless, he brings shameless incidents upon himself.

While Rito does not have any romantic feelings for Yui, and thinks that she is always angry at him, any romance between them is generally seen from Yui's perspective. She has grown to understand Rito well enough that she trusts him not to take advantage of her. Her growing love for Rito surprises even herself. However, being inexperienced with boys and being a typical tsundere, she has difficulty opening up to Rito and often hides her shyness with aggression and anger. On some occasions she would get happy when he compliments something about her, like her yukata.

Ironically, despite outwardly hating sexual pleasures, she seems to desire doing such shameless things together with Rito, as seen when she imagines herself being married to him and being pregnant with his child, and when she offered herself to him in bed on the condition that he only does shameless things to her. Though Rito resisted the temptation, Yui came to love him even more for not taking advantage of her, but she was further perplexed with her actions and her own feelings. She would get jealous whenever he's kind or close with another girl.

In some ways, Rito is good for Yui. He is a kind person and a loyal friend and, despite repeatedly molesting them by accident, is respectful to women. Rito is the only boy Yui knows is far too kind and too cowardly to take advantage of her sexually. He is apparently the kind of boy who can make Yui open up to love. Yui's older brother, Yuu, can easily read her poorly hidden feelings, and is eager to see his sister become more open to romance through Rito.

Momo Velia Deviluke
Rito is not as romantically attracted and attached to Momo as he is with her older sister, Lala, and he notes that Momo is more mischievous and cunning compared to Lala. Rito does grow to trust her and consider her a good and dependable friend, and would want to also be there for her as well. He relates with Momo quite well, and goes along with whatever mishaps she creates much more easily than he does with Lala's mischief. Although he still has difficulty getting used to her perverted tendencies.

Momo, like her sister, is also  in love with Rito, but she is a lot more lustful. She often sneaks into his room and enjoys it when he "plays" with her body while he is sleeping. Because there are other girls who love Rito, Momo constantly tries to get him intimately closer with them and herself, thus creating the Harem plan. She says the reasons for doing this is to make everyone happy, but in truth, it's because she doesn't care whether she is second or third, as long as she is loved by him. Although he shakes it off at first, he slowly considers it, especially after seeing Run's true feelings towards him.

Mikan Yuuki
Mikan is Rito's younger sister. As children, Rito and Mikan were very close, and Mikan still called him "Onii-chan". Because their parents were not often at home, Rito looked after Mikan and they spent their time together all the time, walking and playing outside together. Unlike Rito, who has grown up to become very clumsy, awkward and anxious, especially around women, Mikan has become hard-working, confident, and good with housework, far surpassing her older brother's maturity and reliability. She stopped calling him "Onii-chan" and doesn't quite look up to him and respect him the way she had before.

Nevertheless, the two of them are still very close. Rito always considers Mikan as his one and only precious little sister. And Mikan is happy taking care of Rito at home. Until Lala's arrival, it was still only the two siblings together at home, and at one point, she felt a little lonely from not spending time with Rito lately. At first Mikan enjoyed seeing how Rito's love life with Lala and Haruna would play out, but later, she would occasionally wonder how she still fits into Rito's life.

She may not show it, but she really cares for Rito and misses his company to the point of perhaps having a brother complex. She even joked that they were not blood related. Her possible brother complex may be the reason why she doesn't call him "Onii-chan", less than a lack of respect and more of a sign her wish that their relationship was something other than that of brother and sister. In the manga she blushes when a character mentions him, and whenever he worries about her, she outwardly brushes off his worries and calls him stupid, but deep down, it makes her very happy.

Golden Darkness (Yami)
She was initially hired to kill Rito by Lacospo (one of Lala's suiters), but after learning that Rito is not at all what Lacospo described him to be, she turned on him and spares Rito, but still claims that she will kill him eventually and will stay on earth until her mission is complete (even though the job is technically over). Later she confirms to him that her mission is only an excuse to stay on Earth and warns him not to make her too angry. Yami probably knows that Rito isn't a pervert like everyone thinks and just hates it when he sees her naked (Chapter 77), and she doesn't hesitate to use her powers to give him a powerful punch in the face, despite it not being his fault.

Yami appears to have love-hate feelings for Rito. She convinces him, and perhaps herself as well, that he is still her target. Like other female characters, his kindness slowly grows on her, like when she was feeling sick from overusing her powers and he carried her to Mikado's clinic, and when he protected her from another assassin sent by Lacospo, and when he refused to take advantage of her while she was uncontrollably infatuated with him under the influence of Celine's pollen. She calls him an idiot for showing kindness to an enemy, but also makes it clear that she doesn't hate idiots, sometimes showing a sweet smile that is rare to her. She also notes that being around him makes her feel safe, a feeling she does not often experience in her unhappy life as an assassin (and notes that it reminded her of her life with Tearju). Rito is the only person she has opened up to about her past.

In the beginning, Rito always seemed afraid of Yami whenever she was around, but as the series continues, Rito's fear of Yami seems to have lightened (although he still shows fear of her sometimes) and has shown to care for her. He would get mad for her sake and even worry about her well being, despite him being her target, something she finds strange about him.

Run Elise Jewelria
Run first fell in love with Rito when they accidentally kissed each other (in her male form). Since then, she considered Lala her rival for Rito's heart and has tried many methods to get his attention that would lead to certain misunderstandings, occasionally running towards him and landing in an awkward manner, which greatly annoys him.

In To LOVE-Ru Darkness, Run is now a famous idol. She has also greatly matured around Rito and becomes closer to him on their date. During their date, Rito realizes that he hardly knows anything about her. From this date Rito is now aware of  how deep Run's feelings are towards him, but she is saddened with the fact that Rito would never see her as a real girl while sharing the same body with Ren. This was the case until Run and Ren reached "adulthood", causing them to split bodies. Since then, Run is determined to try harder to gain Rito's affections.

In Darkness Chapter 35, it's possible that Rito is begun to have feelings for her, as dreamed about her naked and kissing him (along with Haruna and Lala). Rito plans on giving her an answer to her feelings one of these days.

Nana Aster Deviluke
Even though she can be abusive, rude and short with him, Rito stills holds Nana in high regard as he does with both her sisters. While she can annoy and even anger him through her thoughtless comments on his 'perverted ways', he does enjoy being around her like all the other members of the household.

He has, multiple times, comforted and helped her through hard times, helping fix her broken friendship with Mea, (with an added hug for comfort), giving her advice about getting along with family and assuring her that men don't care about women solely on their breast sizes.

Rito has admitted to her, (while Momo was in her body), that she has a very unique and wonderful personality, and holds her in high esteem when she proves her maturity on occasion. It is quite possible that Rito may even have feelings for Nana, shown by events such as when he felt embarrassed after hugging her out of nowhere to help her calm down, and almost kissing her when Momo, again in Nana's body, talked to him kindly and offered it to him. In Chapter 35 of Darkness, Nana has shown some concerned about the kind of  complicated  things Rito might be going through.

Mea Kurosaki
Mea is interested in Rito, especially when Nana called him a beast. Mea seems to find pleasure in being licked, and has a deep desire to have Rito lick her body, and to do perverted things with her, which she playfully teases him about, by asking him to do it despite being around other people.

When Rito spoke to her and questioned if some things she learned from her Master Nemesis could be wrong, Mea punished him by controlling him with her psycho-dive ability, forcing him to lick and molest her body, and at the same time sharing the sensations with him, which she believes he finds very uncomfortable. However, she unintentionally shared with him her deeper feelings of being uneasy, lost and lonely, which she angrily continued to deny, still convincing herself that she is a weapon.

Mea was at first opposed to Rito's desire to reunite Yami with Tearju so that they could be happy together again. But recently, after speaking with Rito, she decided to help him persuade Yami to attend classes and see Tearju again, grudgingly accepting Rito's insistence that Tearju sees them as her little sisters and the importance of filling the gaps between them.

Rito cares for Mea, and wants her to embrace friendship and tries to convince her that she is not alone. It's unknown what Mea's true feelings towards Rito are, as she finds his persuasion to accept humanity annoying, yet she still continues to act cheerfully around him.

Celine
Celine was Lala's gift for Rito's 16th birthday. Originally Celine was a multi-story, monstrous, sentient sunflower kept in the backyard of the Yuuki residence. Although seemingly monstrous, Rito cared for her deeply and considered her as family. When Celine seemed to have contracted a deadly disease, Rito was fully dedicated to finding the Luckberry to cure her. With the help of his friends, he journeyed to the S-level danger class planet Misletoe to retrieve the antidote, only to return to find Celine all dried up. But in reality, she was germinating, and from her single seed, she emerges in the form of a human-like infant girl with a flower on her head.

Rito cares very much for Celine and finds her both cute and innocent, taking her for walks, playing with her and watering her along with all the other flowers in the garden even though it's not needed. While he can get annoyed at her for causing trouble for him via Lala's inventions or her childish mind, he still considers her to be one of the largest parts of his life, taking high responsibility for her when he looks after her and makes sure she has a fun life while doing so.

She seems to view Rito as her parent because of how he always takes care of her and because of her child-like appearance and closeness with him, she is often mistaken for his daughter. Even Rito's mother asked who the mother was, apparently not curious who the father is.

Nemesis
Nemesis is a sadistic and demanding girl who planned for Yami to return to being a cold hearted assassin again, starting with killing her target, Rito. Recently, that doesn't seem like the case anymore as she tries to become friends with Rito (in her own erotic way) to observe their lives more closely. She says that he is a fool for trusting people, but despite this, she is very (sexually) interested in him and finds his nervous expressions towards her arousing.

Because of Rito's ability to bring the transformation weapons, Yami and Mea, closer to humanity, rather than leaving him alone she wants him all to herself as her servant, making him do things like massaging her shoulders, commenting and exagerating his technque on pleasuring women, and even sneaking up on him in the bath. Wanting Rito all to herself as her servant, she essentially set herself up as an enemy to Momo's harem plan for Rito, telling her to give up on the plan.

Tearju Lunatique
Tearju temporarily became Rito's home room teacher when she heard that Yami had been staying on Earth and was attending his school. Though she can be somewhat absent-minded and oblivious around him, leading to awkward situations between the two, Rito still seems to respect and enjoy her company, seeing her as a very passionate link to Yami's lighter side and has instantly come to her aid on numerous occasions.

After Yami opened up to him about her past with Tearju, Rito became eager to help them reunite with each other so that they may restore the life and happiness they once had together. When Tearju becomes Yami's homeroom teacher, Rito, with help from Mea, successfully persuaded Yami to return to school, in the hopes that she and Tearju might become close to each other again.

Kyouko Kirisaki
Kyouko is a famous idol who works alongside Run. They first met when Run wanted to introduce Rito as her boyfriend, which Rito agreed to pretend to be. During their meeting, she revealed to him that she is a human/alien hybrid who controls fire. Still unknown to him, Kyouko realized about half way through that he was only pretending to be Run's boyfriend.

Kyouko likes Rito's innocence. U nlike other girls, she  doesn't hit or use her abilities on him  when he sees her naked after a mishap, and she finds him cute when he blushes and likes to make fun of his shyness. Kyouko is very supportive of Run's feelings. During her visit at Sainan High to give a lecture, she was actually there to learn more about him for her friend, but unexpetedly started to develop her own feelings for him after he saved her from a swarm of rampaging fans and carried her like a princess. She has kept this feeling hidden from Run.

Rin Kujou
Rin dislikes Rito's perverted clumsiness, especially around her, Aya and most of all Saki, and doesn't hesitate to hit him for it with her wooden sword (sometimes with a real sword, and on one occasion, she used a gun on him). One time, she and Aya requested, or rather forced, Rito to arrange a meeting between Saki and Zastin, and when he helped them, Rin has shown a slightly better understanding towards him (even willingly smiled at him), but unfortunately, that did not last long before Rito's clumsiness struck again, ending her short-lived respect for him, although she still acts quite formal towards him.

She has shown kindness and hospitality to Mikan, and finds the younger sister to be a lot more reliable than her brother and has a better relationship with her. He has shown to be very greatful when she help his sister when she wasn't feeling well. Mikan agrees with Rin that he can be pathetic and clumsy but tells her that he can be reliable when one is in trouble, however she was unable to seen him the way she does, but eventually does later.

Despite showing resentment towards him, Rito willingly risked his life to save her from being possessed by the  demon   sword Bladix, standing up to the sword's consciousness and expressing about how she has those close to her, which greatly touches her. Afterwards she appears to have changed her impression of him. She is now grateful to him, but this time in a clearly more bashful way, which is highly uncharacteristic to her usual composed and aloof self, and she likely has begun to grow affectionate feelings towards him  ( To Love-Ru Darkness Chapter 33).

Saibai Yuuki
His dad and a manga artist, who constantly asks him to pick up Manga supplies for him otherwise he won't give him his monthly allowence. Though the hardly ever spend any time together, even on the holidays, they both do obviously love and care for one another. Being his father, Saibai often likes to tease Rito about the many girls in his life, much to Rito's embarassed annoyance.

Kenichi Saruyama
Kenichi Saruyama is Rito's perverted male friend. They have been friends for a long time and he is Rito's only real male friend. Saruyama is aware of Rito's crush on Haruna since before the start of the series, and he also understands Rito's incompetence around girls well enough that he wasn't at all surprised that Rito failed yet again to confess his love to Haruna. Saruyama has made some attempts to help Rito get together with Haruna.

Although they are friends, they both have certain dislikes towards each other. Rito doesn't like how other students see them grouped together when Saruyama starts acting and talking like a pervert, and Saruyama (along with almost every boy in the school) envies Rito for being close to Lala and with so many other popular girls, even though he already has feelings for Haruna.

Saruyama has a crush on a girl named Riko Yuusaki, who, unknown to him, is actually Rito, transformed into a girl by Lala's inventions. Saruyama is no less a pervert and a loser around "Riko" as he is any other time when he talks about girls, which disgusts Rito.

Ren Elise Jewelria
Ren sees Rito as his rival for Lala's love, so he tries constanly to prove to her that he is more manly than Rito by challenging him to completely pointless challenges (which Rito doesn't care about and Lala isn't even aware of). During one of their squabbles, Ren accidently kissed Rito, infuriating both boys, and causing Ren to hate Rito even more. Consequently, the kiss also caused his (yet-to-be-introduced) female alter-ego to fall in love with Rito, which Ren also blames him for.

As of To Love-Ru Darkness, Ren seems to no longer make any effort to try and impress Lala, perhaps due to being featured less frequently in the story. It's unknown if he has accepted Rito as the one Lala loves or still tries off-scene to impress her. He does still care about Lala. Ren seems to have since matured from what he was before, and put most of his animosity towards Rito behind him.

He  and  Rito no longer seem to be against each other anymore and may have established a better relationship. However, he reminds Rito how kind Lala truly is and questions him if he is taking advantage of her kindness, which Rito thinks deep down that it might be true. Including Run, Ren advices him  not   to do anything to make girls cry.

Trivia
Rito, along with the other male characters of the To Love-Ru Series(with the exception of Honekawa-sensei)doesn't have a cameo appearance in the manga Mayoi Neko Overrun despite it is drawn with the same artist.
