Boma

Mercenary. A mysterious and silent refugee who is searching for his missing sister Usagi, or Bunny. For punishment of a crime committed in his past, he was transformed into a "beast-human" hybrid - criminals who have committed a crime so grave as to warrant life in prison have beast heads grafted onto their bodies in order to make them regret their sin for the rest of their lives. Boma disguises his wolf-like features with a holographic device. He accepts one job for Clair Leonelli - to destroy J. However, he ends up refusing the job. He is a skilled swordsman and makes a deadly enemy (and later, a powerful ally) for Daisuke and J.
