demon giving an ear as a present to a girl

A folklore professor becomes unwittingly possessed by the ancient Japanese demons of Thunder and Lightning. But when The Bureau of Paranormal Research & Defense dispatches a team of agents to investigate, a cursed samurai sword sends Hellboy to a supernatural dimension of ghosts, monsters, and feudal mayhem. Now while pyrokinetic Liz Sherman and fishboy Abe Sapien battle one very pissed-off dragon, a lost and cranky Hellboy must find his way home.

Hellboy and a rookie BPRD agent get stranded in 1950s rural Appalachia. There, they discover a small community haunted by witches, led by a local devil with a troubling connection to Hellboy's past: the Crooked Man.
