Viridian

A French detective and minor character in the series that makes his first appearance in episode 2. He is a professional painter who also works as an art detective, and possibly, an art historian, as he seemed to know much about the works in the 100-year safe. His ability is trick art (deceiving pictures), which confuses even Joker. He is also shown to be able to paint marvelous works of art in a few measly seconds, in addition to being very passionate about art.
