This is a new anime that I found on Youtube while searching for the voice actor for Cloud. The japense voice actor, he's done this anime anime about an oni eater (oni means ogre) and he's been sealed away only to be released by a young man with a sixth sense of seeing demons. Anyway, together they exorise demons from humans and watch not. During one episode they come across this girl who lives with this woman who has a demon within hey. The young girl first meets Haruka (AKA voice actor of Cloud Stife) when she is being harassed by some guys and he comes to her rescue (hint: Final Fantasy Tactics related?) and thus he is employed by his master (the boy who released him) as a bodyguard. You see where I'm getting with this? Anyways, I'll post the episode on here and everyone can check it outs.
