Akira is an office-worker who was reincarnated as a goblin. His new life as chief of the goblin village has been going smoothly...until a group of humans attack one day. But when Akira petitions Count Orleans to intervene, he discovers that the invaders can't be punished on legal grounds, since Goblins are considered monsters by human society. Can Akira find a way to protect his village before it's too late!?
