A wolf that Komori picked up and keeps as a pet? Identifies as a shark. Appearance: Light blue and fluffy. Has fangs, but they aren't very sharp, so it doesn't hurt much when bitten. Size: About the size of a small dog. Race: Wolf Personality: A bit childish? But kind. First person: I (childish) Honorifics: Azu, Azuzu Komori -> Komo-chan Guest -> Bone Patients -> Bone Apparently sees all organic life forms other than Komori as food. That's why he calls everyone else "Bone." If called cute, he'll threaten you saying, "I'm cool!!" By the way, his threats are more cute than scary. Also, if asked if he's a dog, he gets angry and says, "I'm a cool shark!" A wolf (?) that looks like a small dog but identifies as a shark. Anyway, he's cute. Really cute. Incredibly cute.
