Graveyard no Nejikureta Ie
There is a dead body town (Graveyard) where all corpses from around the world gather. On the outskirts of the city there is a stranger's dead body, the scholar Karon, and a laboratory with the motto of ghastly grave protection. A woman brings a tearing brother's dead body to the corpse street... and so a dark fantasy tale over the secret of a strange corpse begins.
