Maxwell

This is Maxwell, he's a little weird
He only wears mismatched clothes, but he is never satisfied so he's constantly changing clothes in the hopes of someday finding the perfect match
Yes, his smile is permanent
Lucid's only support system and friend
Doesn't really know anything about Lucid's past since he refuses to tell him, but has kind of an idea because of the stuff he blurts out from time to time when in a deep state of sadness (however, prefers to keep those theories to himself cuz touching the subject would probably make Lucid even worse)
