As commanding officer of the UNCM 7th Regiment, Kiryu earned a high measure of loyalty from his subordinates, including Sergeant Hajime Saito, who was a long-time friend of Kiryu's family. Kiryu was gravely injured in an enemy attack against the 7th Regiment's garrison on the Moon in early 2199. He offered encouragement to Saito and the surviving members of the regiment as they awaited evacuation from their wrecked outpost. Despite Saito's attention, Kiryu succumbed to his injuries, not long before a rescue ship arrived.
Almost exactly at the moment of his death, the colonel's daughter, Mikage, passed overhead in the new battleship Yamato as it departed on its first mission (Space Battleship Yamato 2199: Odyssey of the Celestial Ark).
