Akita Toushirou 秋田藤四郎

A tantou forged by Awataguchi Yoshimitsu. One of the Toushirou brothers.

Having been kept hidden away for so long, he is unfamiliar with the outside world and shows an interest in absolutely everything. He also enjoys gathering secrets, making full use of his special talent for playing hide-and-seek. As a result, he sometimes gets left behind—and even forgotten—by his brothers.
