A God Arrives - S1.E1

The protagonist, Kyouhei, moves out of his hometown to work in Tokyo. After drinking quite a bit one night, he and his friend Shiba find a dead body in an elevator. 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. It turns out Aki is responsible for the dead guy in the elevator, having broken free of his imprisonment at Kyouhei’s hometown to follow Kyouhei to Tokyo and wreak havoc.
