Kotegawa Yui

Yui Kotegawa is a secondary female pervert of To Love-Ru and is an uptight, high-strung girl if ya know what i mean, who is in Rito's class during the second year. Yui has little to no tolerance for anything she does not consider to be "acceptable behavior". Her opinions, quick temper, and habit of speaking her mind often results in her vocally reprimanding classmates. Yui quickly grows annoyed and disgusted by eccentricities and bizarre actions, particularly with regards to Rito and Lala.

Unfortunately, almost every encounter with Rito usually ends up with her embarrassed, naked or groped, and although her nature prevents her from easing her behavior, she does slowly warm up to his usual antics. After Rito saves Yui from a group of delinquents, she develops feelings for him. Her inexperience with boys leaves her unable to understand her own feelings and continually denies them to herself.

When Rito usually asks what's wrong, she says the exact opposite of what she wants to say and then yells at him in some way (a typical Tsundere). It was only recently that she has realised that she is in love with Rito, a fact she is annoyed about given her opinion of him. She did however almost try to have sex with him after getting caught in the rain together (on the condition that he only ever sleep with her) and has been seen fantisizing about being together with him.

A common gag is that newer characters cannot remember Kotegawa's family name, presumably due to the fact that she is generally an unwilling participant in Lala's frequent schemes. She also really likes cats – owning cat based books, having a stuffed cat, decorating her room with cat shaped things, shaping her Valentine chocolate into a cat's face, and even having a cat-themed floaty, something Rito seems to find cute about her.

Appearance
Yui has long black hair and dark brown eyes, she is often seen with an angry face. According to Mio Sawada, her measurements are B88, W59, H87, an attractive figure compared to other students (something that other characters like Nana and Haruna feel jealous towards to), which is surprising and ironic considering her rejection of sex and courtship.

History


In her childhood Yui dispised all boys because of how violent, insensitive and above all shameless they can be and stated that they caused her much hardship as a class rep in 5th grade, because of this she thinks that any kind love and romance is shameless since it ment being close with a boy. Her view of this changes slightly when she initially first met Rito when she saw him willingly saving a cat from a tree, the same cat she was unable to save and no other boy she asked even cared (although it was a few years later during a deja vu that Yui remembered this event and Rito's being in it. Rito probebly isn't aware that Yui was that same girl he met, it's unknown if he still remembers her). Yui had the impression that all boys are bad but because of Rito's bravery and kind nature, her impression of this changes and realizes that not all boys are bad (but still finds most of them shameless, even Rito but understands very much that it's not really his intentions).

Relationships with Other Characters
Rito Yuuki Originally thinking he was just another "Shameless" boy, she realized how wrong she was. Her feelings for him began to change to move towards romance when Rito saved her from a group of delinquents. Throughout the series, Yui's love interest in Rito developed. Yui made chocolate for him on Valentine's Day, even though she claimed it was just "Giri (Obligatory) Chocolate," she really made chocolate only for him. In the OVA, at a group picnic, Yui told Rito "I won't let you do shameless things with anyone else but me!!" while she was under the influence of pollen that caused everyone to freely speak their minds.

In To Love Ru: Darkness, while Momo is trying to further her Harem Plan, she manipulated Yui and Rito into being alone together at Rito's house during what appeared to be a rain. During a black out, Rito falls onto Yui. While Rito is on top of her on his bed, Yui puts her arms around him and explains how she has learned to accept that it's normal for boys to be shameless, and that they are not all bad. She then offers herself to him if he agrees to do shameless things only to her (chapter 4). Rito breaks away and explains to her that although he is interested, he doesn't do shameless things on purpose. Yui falls further in love with Rito as she sees his innocent nature and how he is different from what she perceived all boys to be. She surprised herself with what she was doing and how far she went, and is grateful to Rito for not taking advantage of her.

After a little longer she comes to realize that she loves him. Although she still has to put up with a lot of his clumsiness, she knows most of all that he is not a boy who would intentionally disrespect girls or take advantage of them. When Momioka playfully and dishonestly explains her sexual experience with Rito, Yui knows immediately that it was not true, remembering Rito could have done it with her when they were in his bedroom but didn't, and thinks to herself that he is indeed different from other boys, and that he is special.

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. 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.

Lala Satalin Deviluke While Yui is generally very uptight, and in some senses Lala's complete opposite, she still is her friend. Lala's outgoingness with Rito often leads to Yui considering it "Shameless," however it has become a norm with her. Yui shows a slight jealousy towards how close she is with Rito, but strongly denies it herself.

While Lala likes to consider everyone to be her friends, Yui and Lala don't generally bond with each other personally.

Yuu Kotegawa
Yuu is Yui's older brother and a lady's man, which is something that Yui dislikes about him. Yuu is aware of Yui's love for Rito, which she denies. He is eager to see his sister grow to become more mature and acknowledge her first love in Rito.

Risa Momioka and Mio Sawada
There is little evidence that Yui is explicitly friends with Risa and Mio. Because they are always groping other girls, talking about sexual subjects, and just being "shameless", Yui would naturally reprimand them to stop being so shameless, which is clearly not well heard by them. It does not help that Yui has a surprisingly attractive figure, which they pointed out as having a pretty "shameless" body herself. They would occasionally grope her body as well, like they would to other girls.
