Everything in Nazarick is turning upside down! Shalltear tries to become smart, Mare (might be) interested in changing species, and the Ainz Ooal Gown Yggdrasil guild takes a break from high fantasy to go on a...class trip sleepover? But even if things are upside-down, inside out, back to front, or totally out of order, this is still the one and only Overlord: The Undead King Oh!
