Synopsis
I want you to pretend to be your dead brother for only one year. Misasagi City, where Isaiah Kuse landed, was a city for fighting the "beasts" that embody the seven deadly sins.

A "beast" that emerges from the singularity of the earth's vein, eats people, and overruns the city. Only the condemnation garment that imitates the miracle of God and the ninth ritual vessel Nowem in the shape of a girl can counter it.

With Nowem saying, "This city will love you," Isaiah will fight the "beast" in this city as his brother's fake.
