Tokyo is a city where monsters haunt. Kusune, a divine messenger with the power to fight the monsters, and Sai, a priestess who amplifies the power of the divine messenger, fight to protect the people from the monsters. Kusune is basically a lazy person who is not suited for fighting, but the moment he gains the power of the Miko, his appearance changes. But the moment he gains Miko's power, his appearance changes and he releases the power of the "divine wolf." Can the two protect each other in a world where monsters roam?
