Yaona is the prince of Atland and Princess Ririha's younger brother. He has short sand brown hair and olive green eyes. Possessing significant curiosity, especially about new people and events, Yaona acts on this impulse. When Kaina first arrives in Atland, Yaona deliberately skips his formal lessons, anticipating reprimand, solely to meet the visitor from the Canopy. This action shows his readiness to disregard protocol or expectations when driven by inquisitiveness. Details concerning Yaona's background story, development, or involvement in other official media beyond the television series remain undocumented.
