Harlequin

Harlequin is one of Les Dernier Quatre, being the Faceless Court Jester. Later, when Faceless is trapped in space, Harlequin tries to steal Eleonore and make her his wife, but his plans fail thanks to Narumi.

Initially, Harlequin seems like a goofy white demon who talks nonsense and has a stupid voice. However, he is one of Faceless's most loyal automatons. Harlequin is considered an idiot, but dangerous, due to his weather manipulation powers. He is also quite cruel, seen when he tried to drink a child's blood during his forced marriage to Eleonore.

It has been shown that Harlequin has a hidden side, which does not like to be mocked, seen when Pantalone started laughing at him when he said his goal of marrying Eleonore. At this point, Harlequin lost his composure and attacked Pantalone in fury.
