Kazuhito's little sister, who calls him affectionally "Kazu-nii". She loves to cook curry. She has an intense brother complex and she hated Akiyama Shinobou for taking Kazu away from her, she also blames her for his death that she burns her books that Kazu owns. It was suggested that for her to know that the dog is her brother was probably based on her Japanese Shinto belief that the human souls can be reborn as an animal,

She has a bizarre weapon called "Tuna Eater", which has three forms: the default mode is a electric knife, "Genocide Mode" is a chainsaw and "Destroy Mode" is a cannon.
