Joker stands at 5'10", with long silver hair tied in a braid and odd-colored eyes, one red and one gray. His skin is pale and he's athletic and toned. He always wears a black mask, and his outfit is a classy and neat. He fights with dual swords and is inhumanly agile and precise; Joker is one of the few SS-Rank adventurers in all of the land.

Those who are spiritually aligned can tell Joker isn't fully human. He never talks about himself or his past. He's cold, calculating, and aloof.
