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, blue hair and usually appears either unemotional or frustrated.

In episode 18, he is shown to have chin length blue hair in a flashback. He still did not show any major emotion when he was part of a squad.

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.

Nana
Nana is his fellow APE employee. 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.

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.
