However, Kyouhei can’t help thinking the way of death is a little familiar. When he gets home, he runs into his sister Utao, who has followed him to the city with her “Doll”. The Dolls are believed to be some sort of god that can fight for them. However, another acquaintance of Kyouhei’s named Aki appears with his own Doll.
