Себас Тьян

The butler of the Tenth floor of Nazarick, who specializes in unarmed combat, with power comparable with the other Floor Guardians. He has the appearance of an elderly gentleman with a neat beard, but is actually of a species known as Dragonoids. He has a strong sense of justice, like his creator. Thus, he dislikes when the other Guardians kill humans needlessly. Because of their opposite personalities, he and Demiurge don't get along.
