Kohta

Hirano is short and overweight. His weight presumably hinders his endurance, which is why he tends to participate in long-distance shooting at a stationary position instead of defending himself via melee attacks or other high energy-expenditure methods of fighting. He has shoulder-length hairstyle that has bangs reaching down from the side of his temples stretching outwards and obscuring the sides of his face. Like Takashi, he is normally seen wearing the standard male student uniform of his school and is generally seen carrying an assortment of gun-based weaponry. His character may have been based on the mangaka of the same name as the two look similar. In addition to his school uniform Kohta wears a tactical vest with multiple pockets along with an additional ammo belt.

(Anime) * After they arrive at Saya Takagi's house Kohta appears in green coveralls, a white t-shirt, white gloves, and brown sandals.

Before the outbreak, Kohta's demeanor is one that is timid, carefree, and sanguine. Yet, at the same time he was constantly suppressing of his frustration he felt from the frequent bullying he suffered at school; all for the sake of having a "normal" life. As a result, when "they" started to emerge, Kohta was one of the few people who readily accepted to the change needed to ensure his and his comrades' survival, finally being able to unleash all the frustrations that he has accumulated so far. And while normally capable of maintaining a cool and level-headed demeanor (more so than Saya), Kohta has exhibited a sadistic and almost maniacal side of himself, to the point where he actually displays a slasher-style smile that shows whenever he kills "them" in cold blood. Saya once mentioned that Kohta and Takashi are the most likely to snap if things keep going the way they are. He has grown very attached to Alice Maresato and can often be found playing with her. He also seems to have crush on Saya, and is sometimes seen getting jealous when Saya gets close to Takashi.
