Sebas Tian

The butler who, along with the head maid, supports the daily lives of the "Supreme Beings" on the 9th and 10th floors of Nazarick. He is a dragonkin.

Although he is not strictly a guardian, his position is treated as equal to the other floor guardians, and he commands ten male servants, a butler assistant, and the battle maid squad "Pleiades" as his direct subordinates. He is one of the few in Nazarick with a personality inclined towards "good," resembling his creator, Touch Me, in being a person of integrity who believes in protecting and saving the weak. Ainz has remarked that he is similar to his creator even in being frightening when angry.

His appearance is that of a stereotypical elderly butler in a black tuxedo with white hair and a white beard, but his eyes are as sharp as those of a raptor. When revealing his true form, his combat abilities are the best in Nazarick overall, primarily engaging in unarmed combat. His skills include healing through qi techniques and extracting information through domination.

Despite his imposing and solemn appearance, he can sometimes act impulsively out of emotion, and his profile notes that his goodness is more "softness" than "kindness." His creator and Demiurge's creator were also at odds, and he does not get along with Demiurge, who enjoys toying with the weak. Although he maintains a polite facade, they frequently clash in opinions.
