Kohta Hirano

Summary

 * A 16 -year old sophomore student who was often bullied in school, Kohta is a gun otaku (enthusiast) and knows the ins and outs of the firearms and any military-related equipment that the group may comes across. His skills as a marksman has proven to be an invaluable asset to keeping everyone alive. On a one-month trip to America he was trained by the US military contractor Blackwater USA which furthered his obsession over weapons.
 * At the beginning of the story he helped Saya Takagi escape danger, though he only did so by following her orders. His crush on Saya is one-sided as he on occasion tries to ask her out only to be rejected, but she has shown to care about him. His crush has ended since then and he has now developed deep feelings for police officer Asami Nakaoka in the most recent arc. With both parties holding mutual feelings, both expressed their love for the other, and Kohta managed to convince Asami to join the group in their escape. Before leaving the Takagi family mansion, Saya's father entrusted her safety to him and Takashi. Saya once mentioned that Kohta and Takashi are the most likely to snap if things keep going the way they are. He's grown very attached to Alice and will often be found playing with her. His character may have been based on the mangaka of the same name as the two look similar.
