I am not sure if this is in the right section, but I forgot the name of a manga and would like to know the name of it. It is about a man who is referred to as a demon he has this thing inside him like a skull thing on his chest and is an excellent swordsman. He joins some mercenary group and one of the girls I guess you can tell falls for him and jazz, I dont remember much but their were not alot of scans out. Also their was a fight in town I remember a bit where hes fighting someone who thinks he can kill him (because of his blasphemious demon thing). He is considered immortal I THINK (not quite sure...).
