Ainz has a suggestion box and any NPC of Nazarick may anonymously put forth any suggestion they so wish into the box. All suggestion will be reviewed by Ainz and they can stretch form political reform of the newly founded Sorcerous Kingdom to simple quality of life improvements in Nazarick(like shrinking/expanding the territory of the Black Capsule).
What sort of wacky, fun or serious suggestion do you think Ainz will find or put in himself?
(You do not have to say whether or not Ainz will accept or use it. You do not have to say who might have put in the suggestion. You can, but you don't have to :)
