Hachirota Hoshino

Hachirota Hoshino (星野 八郎太, Hoshino Hachirōta), often called Hachimaki (鉢巻, Hachimaki) or just Hachi (はち, Hachi), is the protagonist of the anime as well as the manga. A twenty-five year old debris collector, Hachimaki starts out a little full of himself as he trains Ai Tanabe to perform EVA work, while his ego and hotheadedness are not exactly an asset he is able to provide her with a solid mentor figure in addition to a good understanding of EVA operations. His own mentor was former astronaut and fellow debris hauler Gigalt Gangaragash, who gave him the nickname of "Hachimaki". As the series progresses Hachi enlists himself into the Jovian expedition in an attempt to join the crew of the nuclear fusion powered spacecraft, the Wernher von Braun, on its history-making voyage to Jupiter.
