Zanpakutou: Hisagomaru

Hanatarou is very timid and nervous. His black hair is a bit long and his bangs frame his face. He tends to be clumsy and easily duped. Hanatarou's kind nature and nervousness results him becoming the victim of many bullies and practical jokes. While Hanatarou looks like a wimp, he shows on more than one occasion he is courageous and dedicated to what he believes in.

His zanpakuto has the odd ability to heal instead of injure anything it cuts. The accumulation of damage absorbed by his zanpakuto manifests as a red meter running along the length of his sword. When the meter reaches full, his zanpakuto releases all the damage it has absorbed as a destructive beam that is powerful enough to kill even a menos grande, after which his sword shrinks into a scalpel.
