His Majesty the Demon King's Housekeeper Vol. 11

RUSTY STAINS AND RAGE-FILLED HEARTS

Sakura was called to the Saint King's home to deal with a mysterious rust that is spreading through the Sacred See. This rust doesn't just effect objects, but also human emotions and will--it's even made the Saint King act strangely. Sakura wants to act fast, but an anti-demon group thinks she's to blame for the curse. They kidnap her before she can even try to polish up the kingdom's metals. Now her demon friends have to find her before this hateful group can put her to death!
