Momo Belia Deviluke is Nana's twin, as well as Lala's younger sister. As Gid's daughter, she holds the title of "Third Princess of Deviluke" as she is the youngest out of his three daughters. 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 Kurosaki Mea, whom she hangs out with more often, Momo becomes more attached to Rito and focuses on expanding "The Harem Plan" she has for him. Momo has short pink hair and purple eyes. In the To LOVE-Ru manga, Momo's hair was frizzy, but in the beginning of To LOVE-Ru Darkness she straightened her hair out in hopes that Rito would see her as more mature. She also has two small flowers on her hair. 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 left side while Momo's is on her right side. Her pupils also become thinner and pointed. According to the official databook, Momo's measurements were B78-W54-H78 in the original manga. In To LOVE-Ru: Darkness, the Venus Momo Club members estimated her measurements to be B80-W54-H79. 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 much, with the exception of 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. Sometimes, whenever Momo gets caught up in the moment of imagining an ecchi situation with Rito and some other girl, she has a tendency to drool. 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. She is essentially the complete polar opposite of Rito Yuuki. She seems to enjoy physical pleasure so much that it's difficult to determine whether or not she is mistaking lust for love. One of the main reasons that she fell in love with Rito is because she loves his unintentional lustful tendencies which he shows when asleep. She doesn't care if she is not Rito's favorite lover, and is perfectly satisfied being one of many partners, and hopes that Rito's other love interests are also as willing to compromise and share their love for Rito. She even tempted Rito with an offer of his own "flower garden of girls". Nonetheless, whatever way she interprets love, she at least takes it seriously. She is not willing to show her lustful side to anyone or be groped by anyone except Rito. She turned down the chance to be accidentally kissed by Rito in his sleep, wanting to receive a kiss from him only when he wants to. However, after her mother visits her and questions her if her heart is fine with her plan, Momo begins to see her own Harem Plan in a more logical perspective. While she convinces herself that she would be perfectly content with being a part of Rito's harem, she is now showing obvious signs of reluctance and doubting if she would be truly happy with sharing Rito with all of the other girls. She is very caring towards plants, due to her ability to communicate with them, and treats them as her friends and should the situation be fit to their abilities, her tools and weapons. In fact she notes one of the reasons she fell for Rito was his kindness towards Celine and the plants in his garden, after which she only progressively falls deeper in love with him, which gradually goes from teasing him, to sleeping in his bed, to conducting the Harem Plan all to secure her place beside 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 they do. She also shows a darker and more sinister side of herself whenever her friends are in trouble, and she becomes more mischievous and hostile. Some examples of this are when Nana and Yami were in trouble on Planet Mistletoe, when the VMC planned to beat up Rito, and when Yami, Mikan and Rito were threatened by Azenda. People have generally stated that Momo becomes very scary when this occurs. Momo calls this her battle state, a state which Yami and Mea have noted that she has 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. Many of her perverted antics, while also being for her own enjoyment, are more often than not done to titillate and arouse Rito out of love and lust at the same time. 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, and threatening the VMC to let Rito go and apologize to him after beating him up and promising to do worse. Momo occasionally fiddles with her hair when thinking over important situations concerning either Nemesis or her Harem plan, which she would seem very serious about. Like Rito, she also has an interest in playing video games, most notably when buying love sim games for ideas for her "harem plan".
