Mayumi Yamamoto

Mayumi Yamamoto (山本 真弓 Yamamoto Mayumi) is the younger sister of Nanako Yamamoto who works as a part-time assistant for a manga publisher and deals with a manga artist named Hanamaru, who has a crush on her. She is rather mischievous at times when it comes to her sister, but the two are very close. She knows that her sister is very airheaded when it comes to matters of love. She is also aware that Naozumi Tsuchida has a crush on her sister, and sympathizes with him, knowing that he'll have a hard time trying to get through to her. She is similarly obtuse when it comes to people's affections aimed at herself (Hanamaru-sensei in particular).
