Protagonist of DARLING in the FRANXX. Nickname is based on his designation as "Code:016".
Has blue eyes, black hair, and wears a school uniform that includes sock garters when not wearing his black bodysuit, which is also a pilot suit.
His younger self is most often depicted wearing a fur-trimmed coat with a parka, which is a grey coat that is also a winter coat. His boots are also fur-trimmed boots as well.
Hiro also grows a pair of blue horns later in the series, in episode 17. Because that last element of Hiro's character design is a spoiler in itself, pictures of Hiro with that late addition to his appearance must be tagged with spoilers.
