Several survivors from Heliopolis are brought on board the Archangel and Kira defends them from enemy attacks until they arrive in Alaska on Earth. Kira has strong reservations against fighting, fearing he may confront Athrun and that he may kill a person. After manipulation by Flay Allster, Kira gradually becomes more aggressive when defending the Archangel to the point where he could kill a person without hesitation. During one of the Archangel's battles against ZAFT, the Strike suffers multiple damages by Athrun and Kira is declared missing in action. He is found alive but injured by Reverend Malchio, who transports him to a space colony known as PLANT where most coordinators reside and is ZAFT's homebase. There, his wounds are treated by Lacus Clyne, a Coordinator who befriended Kira when she was taken aboard the Archangel and was used as a hostage.
