Kanara Azekura

Azekura is the holder of the deviant blade Yoroi, which actually takes the shape of armor. He obtained the armor from a pirate band that killed his younger sister and took him to be their servant boy. He took the armor and exacted revenge on them, and then became the leader of a band of pirates himself.

He wanted to make Togame his woman because she resembles his dead sister.

[Spoiler] He is the first of the blade holders Shichika fights whom he does not kill. [/Spoiler]
