ข้อมูลอนิเมะTo LOVE-Ru OVA

As Saruyama tries to explain about boobs to Rito, the girls including Lala overhear the conversation. Lala asks for more facts about boobs and gets the idea that all men are interested in breasts. She makes an invention that will make her boobs the perfect size, but Rito flies out from a school window and crashes into the invention, turning him into a girl. After Lala and Mikan tease him with girl clothing, Rito runs out of the house. He gets bombarded by many men including Saruyama and the principal. Saki finds Rito (still as a girl) unconscious and brings him/her into Saki's mansion. Riko (Rito as a girl) begins to feel that being a girl may be better than being a boy. He/she gets turned back into boy by one of Lala's invention when she appears out of nowhere, and the episode ends when Saki delivers a painful beating upon Rito by punching him in the face with a baseball bat.

Rito is always spending time with Lala; he barely talks to Mikan and creates more work for Mikan to do. Mikan, tired of the situation, suddenly storms out of the house. While Rito and Lala go looking for Mikan, there are few flashbacks of Rito and Mikan in the past including building a snowman. As Rito and Lala look for Mikan, they are intercepted by Saki as she challenges Lala to a barbecue match. Yami comforts Mikan before Rito finds her thanks to Haruna. Mikan feels OK about the situation and teases Rito about Lala and Haruna. They find the same park where Rito and Mikan built a snowman in the past. Lala summons a snow machine to recreate the past event and wishes to see her siblings as well.

Haruna wins a south island resort trip for ten females. She invites Lala and Mikan to the vacation. Rito, thanks to the mess that Lala left behind, activates one of Lala's inventions and gets stuck inside Maron's (Haruna's dog) body. Mistaking it as a bag that Lala left behind (The invention turns Maron into a bag at first), Mikan brings the bag with her, not knowing that she has also brought Rito along with them.

Rito and the others got stuck inside a RPG game made by Lala's sisters, Nana and Momo. In order to exit from the game, Rito and the others must defeat the great demon lord and rescue Lala. Rito, thinking Lala is behind the entire game, makes progress through the game. He does not realize that the real intent of the game is for Nana and Momo to analyze Rito and find out his true feelings. At the climax of the game, the demon lord teleports Rito to her castle and forces him to admit his feelings to Lala. As Rito cannot bring out a definite answer and Lala covered him up, the angry demon lord tries to defeat all of the characters by modifying the game to give her all the powerups and erase their data. Nana and Momo join in by summoning a giant talking Marron and Celine in her plant form and defeat the demon lord.

Nana, one of Lala's sisters, question Momo why all girls including Lala are attracted to Rito. After observing one whole day with Rito, Nana concludes that everyone is mistaken about Rito. Lala, Mikan, and Rito invite Nana and Momo to Hanami, but Momo turns them down, hoping to use this event to prove her statement about Rito. During the event, Momo summons an alien plant that releases pollen which will bring out everyone's true feelings. The pollen affects everyone except Lala and Rito. Nana does not feel convinced and forces the alien plant to release more pollen. The plant becomes possessed by its own pollen and captures Nana and Momo and later Lala. The plant drops Nana and Rito comes to the rescue, changing Nana's impression on Rito.
