Demon Lord

A Demon Lords is a being with great power who are the "greatest terror the Little Garden has ever known." They are of different Species. When a Demon Lord challenges someone to a Gift Game, they cannot refuse the challenge, though it is unknown how and why. Typically, Demon Lords are extremely powerful beings within Miniature Garden, who consider destroying a large community in a single night as child's play. The No Names were one such community that was destroyed by a Demon Lord.

The Demon Lord Shiroyasha is capable of creating gods, though it is unknown if this ability is shared with other demon lords.

All the demon lords shown so far in the anime are lolis.

Ranking
Demon Lords are rank in digits 1 to 6. It was said in volume 3 that a demon ranked 6 can be defeated if a group is made with enough power. A ranked 5 demon lord is strong enough to cover the world in darkness. The rank of the demon lord shows the rank of their community not how strong the demon lord is.

Divine Class - natural gods/ given divinity

Star Class/Celestial - beings superior to the Divine Class, being the group that are on the Giving end and all other inferior classes being on the Receiving end of their Gifts.
