Yūki Rito

Rito Yuuki is the main male protagonist of To Love-Ru. He is a normal 16 year old student of Sainan High, has orange hair, and he has a big crush on Haruna Sairenji. 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 ogling or groping the many girls in the series (though mostly unintentionally). He is generally kind and 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 extraodinary skill in accidently reaching his hands or face into the breasts or panties 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.

Personality
Rito is humble, caring, a gentleman (in principle) and brave when push comes to shove. He's also very loyal, and willing to help out almost anyone when they need it. He's quite shy around women, often looking away when faced with erotic situations. He has also shown that he cares extremely for plants, which was shown in the series multiple times (i.e. when Rito was the only one whou would replace the water in the school's flowers and when Rito's character in the Trouble Quest was that of a florist). Rito was also willing to go to a dangerous planet just to get medicine that can cure his plant's deadly illness. Above all else, he is a very charismatic person, always trying to make people feel better and understanding others' points of view.

History
Before Rito met Lala, it was stated that Rito had difficulty talking to girls. His only friend was Saruyama. However, because of Lala's friendliness, and Rito's close relationship with Lala, all of Lala's girl friends became Rito's too, like Haruna Sairenji whom Rito could not even talk to prior to Lala's "descent".

As a child, Rito always helped with his father's manga then would take Mikan to a shrine nearby to play. One time, during his fifth grade, Rito climbed a tree to help a cat who was stuck. This is the time that Yui first met Rito (although it was a few years later during a deja vu that Yui remembered this event and Rito's being in it). The cat that Rito saved was the same cat that Yui was trying to save prior to Rito's coming to the shrine. However, Yui was not able to climb the tree and save the cat. She tried to ask some of the boys from her class to help her. However, since the boys hated Yui's leadership as the class representative, they ignored her and decided 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 boys are bad.

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). It was also during this time that Haruna began to like Rito. Haruna says that it was because of Rito's affection for the plants in the school (Rito would always refill the water in the flower vase while no one else cared) that Haruna began to notice him. Rito also displayed his strong determination during his eighth grade when his class was lagging behind the other classes during a school competition. However, Rito never gave up, and ended up winning the trophy for his class.

Relationships with Other Characters
Lala Satalin Deviluke 

Rito first met Lala in the first episode of the series when she teleported into his bathtub while running away from home. At first Rito wanted nothing to do with her, even saying that he didn't like her." But as the series progresses, he became very good friends with Lala, and even falling for her romantically. Rito even states that he feels uneasy when Lala is not around.

A lot of times, Rito is willing to risk his well-being 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.

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)."

In the spin-off 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. In one event, after he found out how compassionate she is towards her sisters, he started feeling nervous, and she went to check his temperature. Being so close, Rito's heart raced, causing him to move back, and activating one of Lala's inventions, naturally leading to an ecchi moment between him and Lala (Chapter 10).

As the series progresses, Rito considers Lala and Momo's Harem idea; however, he quickly shakes it off. When Rito teleports to Lala's pocket dimension to comfort Nana, his face teleports in between Lala's breast, tripping them and causing Rito to fondle her breasts while her tail was in between them. Later, when Lala notices Nana's change of mood, she states that it's as expected from Rito, while blushing (Chapter 21).

 Haruna Sairenji  Haruna has been the girl of Rito's affections since before the start of the series. 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.

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. In addition, she is often a target of Rito's perverted clumsiness, being caught in many provacative 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.

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 agression and anger.

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 to 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.

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.

Run Elise Jewelria  Run first fell in love with Rito when they accidently 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 curtain 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. Because of this, Rito realised that he hardly knows anything about her. Rito is aware of Run's feelings 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 mind and body. Since then, Run is determined to try harder to gain Rito's affections.

Momo Velia Deviluke  Rito is not as romantically attracted and attached to Momo the way 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.

Much like Lala, Momo has a strong attraction towards Rito, but more lustful than her innocent and childlike older sister. While she, at first, had a strong sexual attraction toward Rito, she grew to truly be in love with him.

By the start of To Love-Ru Darkness, she has become greatly attached to him and has fallen deeply in love with him. But she knows that if Rito had to choose to love one girl, it would likely not be her. Much of the plot of To Love-Ru Darkness revolves around her "Harem Plan", her plan to bring out the "carnivore" in Rito and make him open to the idea of falling in love with and marrying all of the girls who are in love with him, herself included.

Momo often sneaks into Rito's bed at night to sleep with him. Although Rito is not intentionally a pervert, his bad sleeping habits would cause him to fondle with Momo and play with her tail, which she greatly enjoys.

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.

Kyouko Kirisaki  Their first introduction was when Run asked Rito to pretend to be her boyfriend and meet her friend kyouko, to which he agreed to. He found out that she is a human/alien hybrid who really can control flames. Kyouko told Run that she knew about half way through their time together that he was only pretending to be her boyfriend. Kyouko likes Rito's innocence, as when he saw her naked after a mishap, she finds him cute when he blushed.

She later visits Sainan High to give a lecture, but in truth, she intended to find out more about Rito for her friend Run. She asked Rito to be her tour guide, and later on she asked him out on a date, but she was only kidding and states that he is Run's "prince". Kyouko started developing feelings for Rito when he saved her from a swarm of fans and carrying her like a princess.

Mea Kurosaki
Mea is interested in Rito especialy when Nana called him a beast. Mea has a deep desire to have Rito lick her body which she playfully teases him about it by asking him to do it despite being around other people, she does force him to do it (as punishment insulting her master Nemesis) by using her ponytail to control his movements, while thoughs and feelings are synchronized Rito a feeling inside her saying it's "like a lost child all on your own"  after hering this she quickly releases him.

Rito wants to Mea to embrace her humanity side, something she denise but as the series progress she slowly comes to accept this. its unknown whether she has feelings for him or just lusts for him.

Tearju Lunatique
Tearju became Rito's home room teacher when heard about where Yami had been staying. Tearju seams to understand Rito's kind nature and trusts him completly even pointing out it's like him to notice something thats troubling someone. Rito would like to see Tearju and Yami together and happy like they used to be.

Nemesis
Nemesis is saddistic demanding girl who is the responsible for coming to earth and to tried conviece Yami to return being a cold hearted assassin again starting with killing Rito, that doesn't seem like the case any more as she tries to become friends with Rito (in an erotic way) after closely observing their lives. She says that he is fool for over trusting people but despite this she is very (sexually) iterested in him and finds his nervous expresion towards her arousing.

Because of Rito's ability to bring a transformation weapon (Yami and Mea) become closer to humanity, rather than leaving him alone she want's him all to her self as her 'pet' boy toy even making him do things like when he was massaging her shoulders which she points out that he has some technque on plesuring women, she would as far as to seek up on him taking a bath. She wants Rito all to herself as her servent, this is a problem for Momo to build her harem plan for Rito which Nemesis tells her to give up on.

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 seem to care and Lala isn't even aware of what he's doing). Ren one time kissed Rito by accident causing him to hate even more but caused his female altra ego to fall in love with Rito, which Ren puts all the blame on him for.

In To Love-Ru Darkness Ren hardly makes any effort to try and impress Lala it's unknow if he has accepted Rito as the one Lala loves or still tries of scene although he still cares about Lala, Ren even reminds Rito how kind Lala can be ask's Rito if he is keeping her as insurance in case things with Haruna don't work, something that botherd Rito.

<span lang="EN" style="font-family: 'Times New Roman', 'serif'; font-size: 13.5pt; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN">Kenichi Saruyama  Kenichi Saruyama is Rito's perverted male friend. They have been friends for a long time. 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 envies Rito for being close to Lala and many other girls, even though Rito 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.
