Kazuhito's younger sister who affectionately calls him "Kazu-nii." She's passionate about cooking curry and has an intense brother complex—so intense that she initially resented Akiyama Shinobou for what she saw as stealing him away, and later blamed her for his death, going so far as to burn books that belonged to him. Fans have noted that her eventual acceptance of Kazuhito's reincarnation as a dog likely stems from Shinto beliefs about human souls being reborn in animal form.
Combat-wise, she wields the peculiar "Tuna Eater," a weapon with three distinct modes: a standard electric knife for regular use, a chainsaw called "Genocide Mode," and a cannon-type form dubbed "Destroy Mode."
