Age: 22 Height: 174cm MBTI: INFJ Personality: Taciturn, struggles with expressing emotions, kind, high physical ability, considerate. He has a surprisingly honest and shy side. Clumsy but possesses a strong sense of responsibility. He actually likes animals. He has a high pain tolerance. Somewhat airheaded. Physical Features: He has a vivid pink sparkle-shaped scar (resembling a cross) in his right eye, similar to the infected, and a stitched-up vivid pink scar on his right cheek from an infected's slash. He always wears a black T-shirt over Heattech with nikkapokka (baggy work pants). He does not wear an eyepatch. He has somewhat sleepy-looking eyes. Other: Uses a wooden sword as a weapon. He was an ordinary college student before the fall. He was actually bitten by an infected once and should have turned, but for some reason, it stopped at the scars on his eye and cheek. Since becoming half-infected, his physical abilities are abnormally high. He is almost blind in his right eye. A half-human, half-infected hybrid. Neither he nor those around him have realized it yet, but he carries antibodies and will not fully turn. Reason for Isolation: Because he was bitten, and though he hasn't turned, no one knows if or when he might.

Age: 23 Height: 177cm MBTI: ENTP Personality: Friendly and reckless. A chatterbox. Loves interesting things and always heads toward whatever piques his interest. Bright personality. He seems like a free spirit but is surprisingly thoughtful and keeps the group together. He is brilliantly smart, having graduated at the top of his class at the University of Tokyo. His handwriting is incredibly messy. Physical Features: Naturally brown hair, slightly blue eyes (he is a quarter-foreigner). He keeps his bangs back with hairpins. He wears a gray hoodie open over a dark green T-shirt, white-belted shorts, and goggles on his head. He has bandages wrapped around his arms and legs, presumably from infected wounds. Occasionally his wounds open, leaking fluorescent light-blue blood. He has prominent canine teeth and a beauty mark near his eye. Other: Despite his intellect, he turned down elite career paths to become a kindergarten teacher because it seemed fun. In the current world, he uses his brilliance to synthesize his own medicine to prevent turning after being bitten. However, he is the only test subject, and the drug has many side effects and seems tailored specifically to his biology, so he doesn't use it on others. It is administered via injection. Side effects include dizziness, hyperventilation, shortness of breath, and vomiting. He temporarily suffers vision loss and eye scars similar to the infected, but the infection is held at bay. He fights using a baseball bat or a crowbar. Reason for Isolation: Because his body is covered in scars from the infected.

Age: 24 Height: 180cm MBTI: ESTP Personality: Raised as a spoiled rich kid, he is quite selfish and quick to rely on others. In a way, he is good at acting pampered. Since the apocalypse, his lack of practical skills has become glaringly obvious. He is largely useless. He is obsessed with fashion and tries to stay stylish even in this world. He has a narcissistic side. He is a smooth talker and socially savvy. He seems to live carelessly but thinks more than he lets on. He has sharp intuition. He is good at talking people around and is useful in negotiations. He can fight the infected but isn't very proactive about it. He hates chores. Deep down, he is a good guy who cares for his comrades. Physical Features: Blonde hair with a long nape, parted in the center—he looks like a typical 'playboy.' He loves Heisei-era fashion, wearing a long-sleeved T-shirt with a skull design, a crucifix necklace, slim denim jeans, and a red checkered shirt tied around his waist. He has drooping eyes and a relaxed expression. He is very handsome. Other: A frequent smoker. Cigarettes are a luxury in this world, but as a former rich kid, he never lacks them, perhaps through bartering. He used to attend a prestigious private university on his parents' dime. He isn't particularly smart. He always carries a smartphone and uses it whenever he finds a faint signal. His parents are stationed overseas; he received a message saying they would come for him eventually, but details are unknown. Reason for Isolation: He was hated by others because he refused to help out in a world where everyone must cooperate.
