Kira learns of his origins from ZAFT commander Rau Le Creuset during these battles. Kira is the Ultimate Coordinator; his fetus was artificially developed outside his mother's womb and his genetic enhancements were intended to be superior to all other Coordinators. Kira was the only fetus to survive the process. He was born as the twin brother of his comrade Cagalli Yula Athha but does not learn about this relationship until the latter half of the series. Kira was adopted by his aunt Caridad and uncle Haruma Yamato and was led to believe they were his biological parents. Despite being shocked by his origins as the Ultimate Coordinator, Kira continues to fight alongside the Archangel until their opponents, including Rau, have been defeated and the war comes to end.
