Hato no Senki tells the story of a young man named Hato Yokoyama that plays a game called DDS-NET in which players can fight against demons. He encounters a Pixie being attacked by other demons and protects her. When the game prompts him to kill her to receive an item, he refuses and discovers a strange symbol has appeared on his hand. This symbol teleports him to an area where he meets a young girl that Hato assumes to be an NPC. Cu Chulainn appears addressing the girl as princess and assumes Hato is another demon.
