Overlord: The Undead King Oh!, Vol. 10

Self-improvement is the name of the game in Nazarick—with the exception of Ainz-sama, who couldn’t possibly be more perfect than heal ready is! With the floor guardians shaping up their acts to wind back the time on Demiurge’s doomsday clock, Narberal practicing how not to insult every human she meets, and the Supreme Beings figuring out how to play mahjong from first principles, everyone’s trying their best to live their worst, evilest lives in another always-inspirational volume of Overlord: The Undead King Oh!
