thistle (dungeon meshi)
AKA "the mad sorcerer" or "the lunatic magician", Thistle is the "master" of the dungeon in which most of Dungeon Meshi takes place. He's an androgynous dark skinned elf in the appearance of a long haired boy who has been keeping himself and his entire kingdom alive in a sort of suspended animation underground by way of a demon's magic for over 1000 years.
