Highschool DxG: The Snack Overlord

Devils, Angels, and Fallen Angels these three factions of supernatural beings live amongst humanity in secret. While a shaky peace exists between them, conflicts of their world are kept hidden from humanity at large. However there is a fourth species, one that exists within a dimension parallel to Earth. The Granutes, beings that are mostly secluded from all other forms of life. Originally the Devils and Angels thought little of the Granutes, until they started capturing members from other races to turn into treats. This transgression carried on for decades, nearly leading to a war, until it abruptly stopped. As a result the Granutes were left alone, but closely watched. However a young man who is half human and half Granute might just shake up the current state of the supernatural world with the power of snacks!
