Yamame Hatori

Yamame is a ninja and a relative of Mamoru. She remembers when Mamoru comforted her when she was little; however, she is quite disappointed after seeing the glasses-wearing person he is now. After Mamoru saves her from an animal man Chin Panji, and starts to like him, she apologizes to Mamoru. The next day, Yamame decided to enter his school.
