Alone once more? -Giyuu-

The end of daily suffering? The daily suffering of Giyuu Tomioka in the hopes of making everyone happy if he had instead died. That's what he thought.

The demons inside him were slowly killing his mind. He had slain many demons before so why can't he kill the demons in his mind? Is he too weak to control his mind or is he giving them full power over his mind?

A weak mind if a mind controller would try to control his mind.
