Christopher Ousaka

His fullname is Christopher. Chris is Shou and Kai's cousin (they only found out in episode 2). He is the Crown Prince of Winfield Kingdom. In episode 1, Chris is seen as a room-mates with Kai although it seems that their relationship is more. Like his cousins, Chris is a white-winged and who later escaped with Sena and Shion from Winfield Kingdom.
