His Majesty the Demon King's Housekeeper Vol. 5 (manga)

Sakura's been kidnapped from the Demon Realm and sold to the Sacred See! But ever the paragon of positivity, Sakura settles into her new role of scrubbing sage faster than she can roll up her sleeves. That is, until a young woman named Jerica appears - and some people are convinced that she's the real Housekeeping Saint! When a stubborn stain stumps Sakura, her reputation and trustworthiness end up being smudged and tarnished. That distrust is leading to rebellion.

Rebellion that may interfere with any rescue plans the Demon King might have!
