The cousin of Hanajima.
Introvert and shy. Blames most things on himself, and has a hard time knowing how to handle things.
A black blooded thing that lives in his spine. Can harden itself to make a weapon and appears to be concious. It goes by Ragnarok.
Was raised with little to no love by a woman only using him for expirementations. He recently left her and is going to stay with Hanajima, his cousin, for now.
