Hachi

Hachi (ハチ, Hachi) is a character in Darling in the Franxx. He the commander of defense of APE Operational Headquarters. He is currently based on Plantation 13.

He is voiced in Japanese by Katsuyuki Konishi and in English by Eric Vale.

Appearance
Hachi appears to be a tall, young man. He has shaved, dark blue hair and usually appears either unemotional or frustrated. He wears the standard APE uniform.

In episode 18, during a flashback, he is shown to have chin length blue hair parted in the middle back when he was a parasite.

He gets a vertical scar over his right eye after the battle with the VIRM in episode 23.

Personality
Unlike Nana, Hachi acts coldly towards the children. He refers to them by their code numbers instead of their nicknames. He is rarely shown smiling and shows little sympathy towards the parasites, though he isn't cruel towards them. He seems to have had his emotions suppressed, explaining his cold attitude.

As the series progresses however, he begins to have some sense of morality. He showed concern when Kokoro and Mitsuru were taken away by APE after Squad 13 held a wedding for them. He lamented on how to comfort the children and wished Nana was there for them instead. In episode 22, he helped the children find ways to grow their crops and allowed the remaining 9's to aid Squad 13 in their battle against VIRM in space.

Etymology
八 (pronounced Hachi) means Eight in Japanese, possibly referring to Hachi's code. It is revealed in Episode 17 that he is a former Stamen, but his true code is still unknown.
