Midare Toushirou - 乱藤四郎

Midare Toushirou is one of the Awataguchi blades. Midare is notable for looking rather like a girl and being a bit of a tease. He meets his previous master Hosokawa Katsumoto, and realizes that humans are flawed. Midare gets worried that the Saniwa will become flawed as well, so he returns, changed.
