He has choppy purple hair with two cyan streaks, one in the front and one on the left. His right ear is pierced with a cyan earring. Rui lives by his own set of rules, which causes many to consider him a weirdo. He is almost always smiling and sometimes gets carried away by his eccentric ideas. Despite the apparent riskiness.
