Akitsu continues to fend off Uzume while Kagari begins to lose control of his powers. Then, when Mikogami orders Mutsu to interfere in the fight between Akitsu and Uzume and capture Kagari, Izumi Higa's secretary, Kakizaki appears. Mutsu, realizing it would be useless to fight against Kakizaki and the other Sekireis he brought with him, retreats along with Mikogami and Akitsu.
