Kotegawa Yui

Yui Kotegawa is the third female protagonist of To Love-Ru and is an uptight, high-strung girl 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", ironically despite this seems to secretly desire for Rito to do them to her (where in the OVA 5 she states "you can only do naughty things to me"). Her naughty 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 though 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 Rito. Though her inexperience with boys leaves her unable to understand her feelings and continually denies her feelings to herself.

When Rito usually asks what's wrong, she says the exact opposite of what she wants to say and then hurts 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 Rito asking her on a date.

A common gag is that newer characters cannot remember Kotegawa's family name, presumably due to the fact she is generally an unwilling participant in Lala's frequent schemes. Also she really likes cats – owning cat based books, having a stuffed cat, decorating her room with cat shaped things, shaping her chocolate into a cat's face, and even having a cat-themed floaty, something Rito seems to find cute about her. According to Mio Sawada, her measurements are B88, W59, H87.



Relationships with Other Characters
Rito Yuuki Throughout the series, Yui's love interest has developed. Originally thinking he was just a "Shameless," boy, she realized how she was wrong after seeing Rito's kindness around town. Later at a group picnic, Yui told Rito that she state that "I won't let you do shameless things with anyone else but me!!" Because she was under the influence of pollen that caused everyone who had been in contact with it to freely speak their minds. Yui also made chocolate for Valentines Day, even though she claimed to him it was just "Giri (Obligatory) Chocolate," but really it was only for him.

In To Love Ru: Darkness , While Momo is trying to further her Harem Plan, in which Rito will marry all of the women who love him, she influences the weather when Rito and Yui are walking home so that they go to Rito's house for shelter. Momo sets up a black out which causes Rito to fall on Yui. While Rito is on top of Yui on his bed, Momo thinks of a plan to create a good atmosphere as she thought it might go down as it always does, Yui screaming 'how shameless!' but before she could even think, Yui puts her arms around Rito's head and tells him how she hates shameless things. Then she tells him if he promises not to do any shameless things with anyone else but her then she would do 'it' with him (chapter 4 page 36 & chapter 20 page 18). Before they could even do it, Rito breaks it up and tells her it's all a misunderstanding. This however causes Yui to fall further in love with Rito as she sees his true nature and how he is different from what she perceived all boys to be. After a little longer she finally comes to realize that she loves him. this happens happen after she defends him from something momika says about him that she realizes he would never do. then start to think how he would act and thinks to her self that he is not like other boys he's special then stops and calls herself shameless.

Lala Satalin Deviluke While Yui is generally very uptight, and in some senses Lala's complete opposite, she still is her friend. However Lala's outgoingness with Rito often leads to Yui considering it as "Shameless," however that is the norm with her.

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, something she denies. Yuu is eager to see his sister grow to become more mature and acknowledge her first love in Rito.
