3x12Room ~A Maiden's Feelings~ Episode Summary Aired: Saturday December 29, 2012
Momo plays through several dating sims and takes notes hoping to aid her harem plan. As Momo completes another pathway, she wonders how she can use these concepts to solve the main issue: Rito. Momo wonders when she fell in love with Rito and remembers how Rito shared many interests with her such as plants. As Momo thinks of Rito more, she slowly starts to masturbate. Momo's romantic fantasies of Rito continue throughout school.
At school, a group of boys who share a love interest with Momo form a fanclub titled "Venus Momo Club". As members, the club will dedicate themselves into helping Momo out. At first, Momo appreciates the help such as accepting all her duties, cleaning her furniture, and acting as bodygaurds but as time goes on, the club distances Momo from Rito more, making her unable to spend time with Rito. Momo sees Lala spending personal time with Rito and Rito making accidental gestures with other girls, making her feel left out. Momo's depression reaches the critical point and devises a way to spend personal time with Rito. During P.E., Momo cuts class and wanders off.
Momo's club waits outside the locker room for Momo and learns about her biggest threat: Rito. Because Rito is frequently discussed by the morals committee and Momo lives with him, Momo will not be safe from Rito. Later, Rito receives a message from Momo to meet her in the storage shed. When Rito enters the storage shed, Momo locks the door and tackles him. She feels aroused over Rito and asks Rito how he feels being alone. Momo deeply caresses him and daydreams Rito becoming sexually active with her. Momo continues to seduce Rito until Momo's club finds out thanks to Mea. The club attacks Rito for kidnapping Momo, but Momo blasts back and forces the club to apologize to Rito. In the end, Momo blames Mea for ruining the moment and wonders how she can successfully win Rito's heart. Rito also cannot understand Momo's true intents.
