However, he failed to synchronize with his partner Naomi and was considered nothing but a failure as a pilot. As a result, he did not know where he belonged and struggled to find his place in the world. However, upon being partnered and piloting with Zero Two, he became an official Parasite and found a new reason to live. Hiro and Zero Two were the newest members of the 13th Plantation, piloting a FRANXX called Strelizia.
