A modern high school girl, Sakura, who loves cleaning, suddenly is sent to a strange different world.

Sakura started cleaning without thinking too dirty, but he removed the dirt that he couldn't clean up.
In a strange different world, a high school girl who is a beautification committee is very active in cleaning! Can it really clean the Demon Castle and the Demon King ...!?!?
