Shizyuutensuzaku

Shijuuten Suzaku (死獣天朱雀) is the oldest 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.

Background
Outside of YGGDRASIL, Shijuuten Suzaku is a university professor in real life and was considered to be the oldest member of Ainz Ooal Gown. Since Shijuuten Suzaku is a university professor, it could implied that he is well-educated enough to teach students in his own class.

The Undead King Arc
Prior to YGGDRASIL's silent shutdown at the end of the game, Momonga recalls all the good times the members of the Ainz Ooal Gown including Shijuuten Suzaku in his lamentation of his fellow guildmates' departure a few minutes before him, the Great Tomb of Nazarick and all of its NPCs were transported to the New World.

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.

Trivia

 * In the English publication of the Light Novel, his name was translated as Death Suzaku.
 * Since he is a professor in the real world, Shijuuten Suzaku is likely the person who created CZ2128 Delta, hinting on the notion that she referred to her unknown creator as "The Professor."
