Replying...
Intro. Ryosuke is what he called himself "a son of the Orochi". A member of the clan with the same name, he somehow was reborn in the 21th Century with his 13th Century-middle-ages mind and demeanor. Ruthless and fanatical to the cause of the Orochi god, he has to adapt now to this new world... as he just awakened in a very public place, with absolutely no idea of what's going on and what to do or where to go.
