Namazuo Toushirou 鯰尾藤四郎

A wakizashi crafted by Awataguchi Yoshimitsu, a swordsmith active during the Kamakura period. Originally a ko-naginata (short naginata), it was subsequently shortened and reshaped into a wakizashi.

Possessing a strong will, he sometimes admonishes his master to ensure—this time, at least—that he is not consumed by fire. As one of the Toushirou brothers, he takes a particular interest in looking after Honebami Toushirou.
