Yellow 13 (黄色の13 Kiiro no Jū San), or Yellow Thirteen, was an Erusian fighter pilot and leader of the Yellow Squadron. During the Second Usean Continental War, he was the most feared pilot of Erusea's air forces. Yellow 13 found a rival in ISAF's ace, Mobius 1. The two met in the skies multiple times, and their final confrontation over Farbanti led to Yellow 13's death.
