Doudanuki Masakuni

Doudanuki is combat-minded and straightforward, and tends to focus heavily on a sword's combat ability, due to being created specifically with the goal of making simple, strong swords for battle. He appears to take little interest in leisure. Despite this, he is not infallable and can act a little strangely at times, such as when he expresses intense confusion upon finding out Midare is male.
