Momoko Matsumoto/Relationship

Riku Tanaka
Momoko refers him as "Teacher". In Chapter 1, Momoko and Riku's relationship starts off on very shaky ground, as she was forced to live in the same room with him as a request from Aunt Ren. At the beginning of the story, Momoko would prefer to kill Riku than be forced to listen to someone who, in her words, has glasses, no athletic powers, and being her teacher. However, as the story progress, she gradually softens up to Riku and even begins to smile after witnessing his kindness and compassion towards others, including herself. In Chapter 3, she seems to be developing some feelings for Riku after he tutored her with English. As Momoko's teacher, it seems that Momoko harbours some romantic feelings for him, but she is too proud to admit it. As the focus of much of Riku's rude advances, she is quite happy to put him back into place with her fists. Although she can be hot headed, Momokos is a good friend and cares for those close to her.
