Hiro is childhood friends with Ichigo (Code:015) and Goro (Code:056). He is partnered with Zero Two (Code:002) and pilots the FRANXX Strelizia.
Hiro (Code
016) was once known as the prodigy amongst the Children (Kodomo). He failed to synchronize with his partner Naomi (Code:703) time and again so now he is considered nothing but a failure as a pilot. As a result he does not know where he belongs to and is troubled by it. But everything changes when he meets the mysterious girl known as Zero Two (Code:002).
