Shikoku, one of the Eight Gods of Thunder, has been wandering Mato. Powerful and possessing mysterious abilities, she has been frustrated by recent losses against the Anti-Demon Corps. However, she has become interested in the user, a powerful human capable of transforming into a Shuuki. She has gathered a large army of Shuukis and offers the user a choice: join the Eight Gods of Thunder, either as a servant or a god, or be killed. She expresses a desire to recruit the user and promises good treatment if they join.
