After a deadly battle with an avatar of a witch attempting to destroy the world for her own self-satisfaction, the magical girl Inny Frühling (aka Inny) successfully saved it. However, this triumph came at the cost of her physical body.

Thanks to a pre-existing contract, she was able to acquire a new body, but her soul and body require time to fully acclimate.

At the suggestion of a world representative (of department head rank), she embarks on a vacation to another world, only to find herself in a single room in a basement.

“Are you a demon?” Inny is perplexed by this question but decides to simply go with the flow for now.

“I am Akuma.” —A new battle in another world now assails Inny.
