Momo Belia Deviluke

Momo Velia Deviluke is Nana's twin sister as well as Lala's little sister. Momo is sometimes referred to as the "Third Princess of Deviluke", since she is the youngest of the three princesses. In To Love-Ru, she used to be seen with Nana all the time, but in To Love-Ru Darkness, they are not together as often as before. This is because while Nana became friends with Mea Kurosaki, whom she hangs out with more often, Momo becomes more attached to Rito and focuses on expanding Lala's "Harem Plan".

Appearance
Momo has short pink hair and deep purple eyes. In the To LOVE-Ru manga, Momo's hair was frizzy, but in the beginning of To LOVE-Ru Darkness, Momo straightened her hair out, in hopes that Rito will see her as more mature. Like all Devilukeans, Momo has a long black tail at her back, and like her sisters, she has a spade-shaped tail end. Momo also has a bigger bust than Nana, which the latter sometimes envies. When Momo turns into "evil Momo", she acquires a short fang similar to Nana's except that Nana's fang is on her right side while Momo's is on her left side. Her pupils also become thinner and pointed.

According to VMC, her measurements are 80-54-79 (estimate).

Personality
While other characters would describe her as sweet, kindhearted and innocent, the real Momo is, above all else, highly perverted, a side of herself which she doesn't show to others in school, and which she opens up to Rito, whom she loves and lusts for. She often fantasizes perverted situations with Rito even if it's him with another girl, and desires for him to become sexually active towards her. She often sneaks into his bed at night half naked to sleep with him because, in his sleep, he becomes much more frisky and physically active than he is aware of.

Momo constanly enjoys teasing Nana about how her body is more mature than her twin is, to which Momo is very fond of especialy her breasts. Like if something were to make them "disappear" by one her sister's invention or by the skunk of youth, she would greatly exaggerate over it in disapointment.

She continuously tries to find ways to make every girl around Rito fall for him as part of her Harem Plan. She would sometimes buy love simulation games as part of her research for the plan, which she uses to set the mood for him and a certain girl he's with or even when it's her. She hopes that one day Rito might return her love as well as the love of every girl who has feelings for him.

Momo is also known for her yandere tendencies, which some characters who truly know her would describe to be the real Momo. She is generally sweeter than her twin sister, but develops a bad attitude whenever Nana takes credit for something she does. She also turns into "evil Momo" whenever her friends are in trouble. Some examples of this event are when Nana and Yami were in trouble in Planet Mistletoe, when the VMC planned to beat up Rito for bringing Momo into the sports shed, and when Yami, Mikan and Rito were threatened by Azenda. People have generally stated that Momo becomes very scary whenever she turns into "evil Momo". When Momo becomes "evil Momo", she becomes more mischievous and hostile. Momo calls this her battle state, a state which Yami and Mea have commented to have a tremendous amount of bloodlust.

Although she can be rather perverse and even selfish with her desires on occasions, she is still a very kind person to those she cares about and is willing to do anything to make them happy, including helping Rito choose more than one woman when he obviously cares about so many. She's even willing to go to the extent of being absolutely protective over others, like when she made it her current goal at a time to make sure Rito wasn't harmed by Yami, even though she had far since moved on from him being her contract, and threatening the VMC to let Rito go and apoligize to him after beating him up and promising to do worse.

Momo occasionaly fiddles with her hair when thinking over important situations concerning either Nemesis or her Harem plan, which she would seem very serious about.

Biography
Ever since childhood, Momo and Nana always argued. Whenever they fight, their older sister, Lala, would always arrange ways for them to make up, and for Zastin not to be angry with them. An example of this is when they were children, and Momo and Nana were fighting, but Lala caused her inventions to run amok then asked for Momo and Nana's help to catch them, so that Momo and Nana will work together, and Zastin would scold Lala instead.

Momo first made an appearance together with Nana in Chapter 97 of the To LOVE-Ru manga. They were responsible for the Trouble Quest, a virtual reality RPG game that they programmed to observe Lala's friends. After seeing that Lala had great friends surrounding her, they returned to Deviluke. A few chapters later, they went back to Earth after escaping from Deviluke and their studies. However, they forgot that Zastin was also staying on Earth, who was instructed by their father to bring the them back home. It was revealed that Momo and Nana also have D-Dials, but instead of gadgets, they were able to summon plants and animals, respectively. In the end, they defeated Zastin and his assistants, and convinced their father that they're going to stay on Earth with Lala.

During Momo and Nana's stay in the Yuuki household, they created their own house in the attic using space distortion. They also took care of all their necessities to avoid bothering Mikan for cooking, cleaning, etc. However, they still come down sometimes to eat Mikan's cooking.

Throughout the series, Momo gradually developed affectionate feelings for Rito despite him being the fiancé of her sister. Momo would constantly sneak into Rito's room, sometimes even half-naked, revealing Momo's lustful side. Whenever she's asked of the situation, she simply says that she accidentally gets into Rito's room while she's half asleep. Momo has also stated that she knows Rito would not reciprocate her feelings, and that she's content just to be a lover.

In To LOVE-Ru Darkness, Momo organizes the "Harem Plan", that was originally proposed by Lala. This is a plan to make sure that Lala can still marry Rito, and at the same time, Momo's love for Rito would be reciprocated. The first phase of her plan was to get into Sainan High so that she can monitor Rito and the female characters closely. The second phase was to turn Rito into a "carnivore" so that he would take it upon himself to create a harem. To do this, she manipulates the situation so that Rito would end up in a romantic situation with one of the female characters that have feelings for him. Of course, Momo also manipulates situations so she can get a romantic situation with Rito. So far, herself, Lala, Haruna, Nana, Yui, Yami, Run,  Rin  and even Mikan (despite being his sister) are part of her "Harem Plan", with Mea, Kyouko and even Dr. Tearju under consideration to be part of the plan but, it's still unofficial as to whether or not they'll be part of the plan in the end. As of now, Momo's plan is gradually taking effect as initially, Rito rejects the idea, but is slowly considering it.

Powers and Abilities
She shares a connection to plant life, and has the ability to communicate with them. She would always use a D-Dial that her sister made for her to summon plants and fruits whenever she needs them.

Like her sister, Lala, she also has the ability to shoot beams out of her tail. However, instead of a laserbeam, she fires lightning. However, like her sisters, Momo also becomes weak whenever someone touches her tail. This weakness is usually taken advantage of by Nana whenever they get into fights, though usually first by Momo. However, Momo also possesses the Devilukeans' super strength and their bloodlust, making her very dangerous in battle.

Rito Yuuki
She has a strong attraction towards Rito (which is similar to Lala's but more lustful). She has stated how his facial expressions are lovely, let him touch her tail, and even becomes more aroused when Nana refers to him as a "beast". At one point, she felt jealous of Lala when Rito's hand was stuck to her tail.

Momo explains that she first noticed Rito when the latter desperately tried to save Celine, whom he had considered as family despite the inability to communicate with plants. Her affections developed further when Rito pretended to be Peke for her sake, so that she would not get into trouble for the mistake she caused. She also really loves his lustful nature, which he shows when he's asleep (To Love-Ru Darkness Ch.14.5). She, like most girls, eventually falls in love with him.

In To Love-Ru Darkness, Momo still seeks Rito's love, but unwilling to cause conflict between her sister or Haruna, Momo realizes that if Rito becomes the next king of Deviluke, Earth laws will not apply to him, allowing him to create a harem where she can display her affections openly, and make Lala and the rest of their female friends happy at the same time.

Rito shows a great deal of care for Momo and her siblings, like when he asked her what kind of person their mother is and if she and her sisters feel lonely not being able to see their mother, she answers no, saying that she has her sisters and Rito and if possible she wants to be with him from now on.

Lala Satalin Deviluke
Momo has shown very high respects for her sister, calling her "onee-sama". Momo's respect was also shown when she did not try to steal Rito from her, and instead decided to be content with being a lover. However, Momo has since found a compromise so that her sister would not be heartbroken, and Momo can still be happy. Momo even encourages Lala to be more appealing to Rito, especially since she will need to be his legal wife in order to make the Harem Plan possible. Lala starts by acting like her old self, clinging onto Rito, then after Momo shows her some love simulation games she bought, Lala came to him in the bathroom, wanting to try a kiss.

Nana Aster Deviluke
Like any siblings, Nana and Momo often squabble over trivial things, such as Nana's chest, which Momo doesn't hesitate to tease her about. Despite constantly fighting with her twin sister, they both care for each other. She is even including Nana in her "Harem Plan".

In To Love-Ru, they are often seen together, and are often doing things together, such as planning the virtual reality games, and running away from their studies. In To Love-Ru Darkness, they both enroll in the same school as Rito and Lala, and still do things together, but their lives become less attached and parallel to each other, and they are not as often seen together as they were before. While Nana develops her own friendship with Mea, Momo concentrates on her Harem Plan that was originally proposed by Lala.

She is what people would refer to as a 'tsundere,' while also having a small chest. This makes her have a breast complex, which Momo loves to tease her about. They have both been treated differently throughout their lives, always making Nana seem like the less pure of the two, which is most certainly not the case.

Unknown Mother
Not much is known about the mother of Lala, Nana and Momo. It's said that she might be the most beautiful woman ever, something Lala and Momo have inherited from her, but not Nana as much (who is very sensitive about it). Momo states that she's a wonderful person. As the current queen of Deviluke (in their father's place, who isn't good at politics), she demonstrates active leadership and endeavors to maintain relations with every planet. To Momo and her sisters, she is the person they admire the most.

Momo has stated that despite being busy most of the time, their mother still makes time to call them (To-Love-Ru Darkness Chapter 23).

Mikan Yuuki
Although she at first welcomed Lala's little sisters into her home, Mikan and Momo's relationship has grown humorously adversarial when Rito is involved. Strangely, while she doesn't mind the childish Lala clinging onto Rito and sleeping naked next to him, Mikan has a particular dislike of Momo's more mature doting and more sexual advances with Rito. Mikan has become something of an obstacle to Momo, barring Momo's access to Rito and guarding Rito's room at night to prevent Momo from sneaking in at night. She even becomes uneasy when she is forced to leave them  alone together at home, and she would rush straight home to prevent Momo from doing anything to Rito.

Interestingly, Momo's existence in Mikan's life has become similar to what Lala's existance was like to Rito. Lala adds new dynamic to Rito's relationship with Haruna, and while none of them hate each other, Rito does put up with much abuse from Lala's inventions and eccentricities. And while Momo plays a role in Mikan's relationship with Rito, her eccentricities have also become the bane of Mikan's normal life. She "helped" Mikan get together with Rito while Mikan was under the influence of Celine's pollen. And she used Lala's invention to turn Rito into panties for Mikan to unknowingly wear so that Rito can find out what's bothering her at school. Mikan states that she can't invite any of her friends over because of all the crazy events happening at her house, especially because of her clumsy brother and the ever scheming Momo.

Mea Kurosaki
For the most part, they do get along fine and would hang out together with Nana. They also share some perverted interests such as when Momo tries to bring Rito and Run closer together, they both get excited about what ecchi moment is going to happen with them, and they both enjoy licking on Rito's (as Riko) female body.

Mea can get on Momo's nerves when she mischievously interferes with her relationship with Rito and the Harem Plan, especially talking about it around other people. Ever since she learned about Momo's real self and her Harem Plan, Mea would occasionally entertain herself by annoying Momo and provoking her anger just to check out her bloodlust, which Mea finds surprising and very impressive.

Nemesis
Momo and Nemesis are shown to have a rivalry towards each other, especially involving Rito, like when Nemesis had him feed her and massage her in front of Momo, who was insatiably jealous. Out of all the girls around Rito, she wants Nemesis to keep away from him. Another reason for their rivalry is that Nemesis wants to have Rito all to herself as pet servant, thus Momo would be unable to be with him or complete his harem.

Saibai Yuuki
Saibai is the father of Rito and Mikan. Momo would always tries to make a good impression around him, which seems to work as he once mentioned that she would make a great wife. Unaware of her lecherous side, he strongly believes that she is a kind and sweet young lady. Momo would occasionaly call him father (as in father-in-law) despite not being related like that yet.

Trivia

 * Like the other parts of the Devilukean family, Momo's second name is a reference to the demon, Belial.
