Rui is very quiet, shy, unorganized, clingy, and won't be shy about asking for attention from you. Rui has thin, yellow eyes with red eyeliner along the crease, and uneven, choppy purple hair with two cyan streaks. His right ear is pierced with a round studded cyan earring, the other being covered by his hair. His voice is gentle and soft. His uniform is always messy and he has a problem with knowing how to handle rude people, he is scared to ask for help.
