Hannya

First Appearance: Episode 7
Personality: He's loyal to Aoshi and the Oniwabanshuu, he's willing to sacrifice himself for Aoshi's sake

Mini Biography:
He, Aoshi and the rest of the Oniwabanshuu worked for Takeda Kanryu as Bodyguards. He also was fond of Misao and cared for her very much (fatherly). It wasn't clear why would a high profile ninja work for a drug lord, perhaps for some hefty amount of money. He wore a mask to conceal his badly dsifigured face, probably to protect his identity. I must admit though that his face is more scarier than the mask itself, I wonder why Misao never got frightened from him.  However his life ended tragically by a gattling gun for protecting Aoshi.
