I feel myself going deeper inside you!
~ Hiro to Zero Two inside the Strelizia (of course, not that kind of deep).

Hiro (ヒロ Hiro) is the main protagonist of the DARLING in the FRANXX series. He was known as a prodigy Parasite with the codename "016" of Thirteenth Plantation, where he's partnered in a boy-girl pair to pilot a FRANXX.

He is voiced by Yuuto Uemura in the Japanese version of the anime, and by Matt Shipman in the English version of the anime.


Hiro has a standard "slim" male physique with black, shaggy hair and rich blue eyes. His checkered past has left him with an emphatic expression on his face, despite his personality.

As the story progresses, after he survives from three times to rides with Zero two, Hiro begins slowly develop his "Saurification" in episode 13 where his canines start to grow. In Episode 16, he begins to grow a tiny blue horn which becomes more visible until episode 23, where his eyes also change from dark blue-green into bright electric-blue just like Zero Two's red pupils.

In Episode 24, His horn now becomes longer like when Zero Two's as a child, and now develop his fang. Shortly after their success to defeat VIRM, Hiro who later fully a human-klaxo hybrid have blue skins and gray scleras like most of Klaxos-sapient in flashback and 001. 


A former star student of the academy, Hiro's inability to pilot FRANXX has left his hopes low, even to the point of choosing to leave Cerasus until his former partner Naomi encourages him to stay. His emotions are strong, but his heart keeps him from giving up.


Hiro came from the same orphanage as Naomi, Ichigo and Goro and later become Naomi's partner.

They failed the exam and Naomi was forced to leave Plantation 13. Hiro, however, was given special permission to stay, which he declined. Naomi's plane was attacked by a klaxosaur, but she survived.


Hiro's nickname may use some of the numeral's readings from his real name "Code:016": hi from 1 ( hito) and ro from 6 ( roku).


  • It is revealed in Episode 3 that Hiro has a chance of being a "special specimen", due to his inability to pilot a FRANXX except for Strelizia with Zero Two.
