Hachi

Hachi (ハチ) is the commander of defense of APE Operational Headquarters. He is currently based on Plantation 13.

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.

When he gets injured during the battle with the VIRM, his right eye is now permanently closed and has a vertical scar over it.

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.

Nana
Nana is his fellow APE colleague. Because of their similar positions within the plantation, they often discuss their plans together and what their actions should be. A flashback in Episode 18 shows that they were teammates in their parasite days. Albeit vaguely,Hachi displays concern for her. He was the one who pulled Nana out of her FRANXX when it crashed. Even when she relapsed into puberty,he continued to keep her around until eventually she was detained by the authorities. In episode 22 when Nana asked why didn't he just leave her,Hachi remained silent.

Dr. FRANXX
Hachi respects him as a superior and seek advice from him from time to time.

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.
