Ryu Kou

Ryu Kou is the prince of the Sana region of Angara and one of the most important non-player characters in Golden Sun: Dark Dawn. He is a hot-headed youth who comes across as arrogant, but is ultimately selfless in his motivations.

When his younger sister, the princess Hou Ju, went to the beastman capital of Belinsk in Morgal, the Morgal king, Volechek, had her captured and held prisoner in his castle. Ryu Kou and his mentor, the aged martial artist Hou Zan, attempted to infiltrate Belinsk Castle but were unsuccessful, but they were allowed to escape with ease. Ryu Kou and Hou Zan make it to the safety of the nomadic village of Te Rya in the glacial midst of the Khiren Mountains, where Matthew's group of Adepts encounter him for the first time. Ryu Kou and Hou Zan eventually climb back down into Morgal by scaling the sheer mountain face, while Matthew's group crosses into Morgal through the Teppe Ruins.
