Garnet

Garnet (ガーネット) is a guild member of Ainz Ooal Gown and regarded as one of the Forty-One Supreme Beings by the NPCs of the Great Tomb of Nazarick. He is the creator of CZ2128 Delta, one of the members of the Pleiades.

Main Equipment

 * Ring of Ainz Ooal Gown: It allows the user to freely teleport between every room inside Nazarick. Every member of Ainz Ooal Gown was required to wear this ring.

Momonga
His friend Momonga is willing to mass produce the "1 yen sticker" he created to help out his NPC, Shizu, when she does not have any much of them left after using it.

CZ2128 Delta
He specially made the "1 yen sticker" for Shizu, so she could paste one on the things that are to her liking.

Trivia

 * Garnet appears to have the nickname "Professor", since Shizu calls him like that.
