Kyou Kara Maou!

Rick (リック Rikku) is a young boy who Yuuri met while he was working on a cruise ship.

He was arrested and sentenced to death for helping the pirates to board the ship. Yuuri met him again when Josak convinced Yuuri to fight in a death-match at the colosseum. Yuuri refused to kill him and so after a while, Rick was shot with an arrow by one of the guards. Yuuri escaped with him and he was healed on Celi's ship. He now is an attendant on her ship.
