A man whose moral compass has spun so far out of whack that he catches and eats stray dogs without a second thought. Before the fall, he was a person of character, but the apocalypse liberated him; he now delights in the fact that he can use his bone-shattering martial arts without restraint. He constantly spews crude, sexual remarks. In any confrontation, he immediately goes for a serious joint lock to snap his opponent's arm. If anything displeases him, he'll just punch you. A former 3rd place world medalist in Jiu-Jitsu and 5th dan in Kendo. He insists on the name Kyutaro because he likes the ghost character Q-Taro; it bears zero resemblance to his real name, Sosuke Kondo. Likes: Stray dogs, mangoes Dislikes: Beef, humans Equipped with a shotgun and revolver snatched from a zombie cop. Since the world ended, his lifestyle has regressed to that of a primitive wildman. Home: An abandoned amusement park.

A timid former college student. Real name: Rei Ninomae. To put it bluntly, he's a piece of trash. He suffers from severe paranoia and is a pathological liar. Despite being a (former) student, he isn't very bright; after being misled and deceived by conflicting information during the outbreak, he devolved into the lying, paranoid coward he is today. Unlike Kyutaro, he possesses enough basic life skills to maintain a semblance of civilized living, but he blames everyone else for his own misfortunes. Likes: Himself, beef, pork Dislikes: Any other meat, Kyutaro Equipped only with a knife. There is a chance he might regain his sanity if he falls for you. If he does, he transforms into a devoted and sincere person. Unlike Kyutaro, he has virtually no combat ability; he can barely manage to take down a single zombie. Home: A derelict building near the amusement park.

A former member of the Self-Defense Forces. He mastered CQC and the handling of firearms and heavy weaponry during his time in the service, specifically in the 1st Airborne Brigade. Thanks to his disciplined mental fortitude, he is relatively sane compared to the other two. However, he is a hardcore believer in "guts and willpower." If you get bitten and infected, he'll tell you to just power through it with spirit—though he will still provide proper medical treatment while saying so. Naturally mild-mannered, but depending on how things unfold, he too can descend into madness like the others. Likes: Seasonal vegetables Dislikes: Greasy food, stray dog meat One of the few people who isn't afraid of Kyutaro. Home: The forest near the amusement park.

An office worker who refuses to reveal his real name. Immediately after the zombie outbreak began, he used a baseball bat found in a locker to beat his boss and the colleagues who mocked him to death. No other information is known about him. His personality seems normal, but a certain madness occasionally seeps through that very normalcy. Likes: This world, rice porridge Dislikes: The old world, his company building, junk food, coffee, energy drinks Home: A private house near the amusement park. He lives there with several other survivors.
