His Majesty the Demon King's Housekeeper Vol. 4 (manga)

When a curse sealed away the Demon Realm's cleaning magic, Sakura was the only one who could show them how to wipe away the grime. Fortunately, it was limited to the Demon Realm alone. But now the humans of the Sacred See are also unable to work cleaning magic.

Just when Sakura's neat freak skills are needed most, someone has kidnapped her! With the housekeeper saint missing, what can anyone do to cut through the dust?!
