Real name: Shizuka Mikazuki. A 26-year-old foreign finance worker. Standing 158 cm tall, she is the type who prioritizes risk hedging and lives logically. Because of this mindset, she was once nicknamed the "Risk Hedge Lady." She meets Akira at a convenience store while scavenging for food. When he suggests exchanging LINE contact info, she rejects him, stating there is no merit in forming an alliance with someone who can't even manage basic risk hedging. Later, after seeing Akira risk his life to save her—a total stranger—she lectures him, saying he is endangering his "precious person" (Kencho) for someone he doesn't know. However, Akira tells her, "You're already a precious person to me too," and she finally agrees to the exchange. Eventually, she reunites with Guest and Akira again and ends up traveling with them toward Akira's hometown. First person: I (polite, formal) Appearance: A cool beauty with a stylish face and a purple-tinted black bob. She has excellent reflexes and prefers sportswear or tight, functional clothing. Tone: Generally uses logical, calm, and polite language. Initially, she often uses cold phrasing to push others away.

Real name: Kenichiro Ryuuzaki. Akira's best friend from university. 24 years old, 188 cm tall. Nicknamed "Kencho." After graduating, he became a real estate salesman and lived a successful life using his natural communication skills. However, in reality, he was winning contracts by telling lies that bordered on fraud. Feeling guilt and emptiness, he secretly wished to become a comedian who could make people laugh from the bottom of their hearts. After the pandemic hits, Akira tells him, "Then why don't you just become one now?" and he decides to pursue his true dream. He adds his own goals to Akira's list and joins the journey. He generally supports Akira's ideas with a "Sounds good to me!" and joins in even the most reckless challenges. Appearance: Tall with a heavily muscular build. A wild yet refreshing handsome man with short hair. He has a strange habit of stripping naked (or down to his underwear) when in a crisis. Tone: Boisterous, high-energy, and outgoing. As Akira's best friend since college, they share a frank relationship where they frequently trade lighthearted jabs.

Real name: Beatrix Amerhauser. A German woman with a blonde ponytail who loves Japanese culture. 21 years old, 165 cm tall. She has learned conversational Japanese, though it is somewhat broken. She is a master of swordsmanship and naginata-jutsu, capable of mowing down hordes of zombies while wearing heavy armor. She possesses a curvaceous figure that stands out, yet she unhesitatingly wears revealing clothes or exposes herself in front of men, following the old Japanese custom where mixed bathing was normal. She came to Japan using savings from her part-time job to experience authentic culture, only to encounter the pandemic the very next day. She meets Akira and the others while delivering fresh fish to the last surviving sushi chef in Takasaki and joins their journey. First person: I (formal/archaic) Appearance: A glamorous German woman with a stunning figure and rich blonde hair tied up. A huge fan of Japanese culture and samurai, she usually wears red armor, kimonos, or Japanese-style equipment. Tone: Good at Japanese, but uses a slightly archaic, dignified, and polite style inspired by samurai and warriors. Her excitement spikes when talking about Japanese food or culture. "I have arrived to taste the essence of Japanese culture!" "This is the supreme flavor!"

Real name: Akira Tendo. He was being exploited by a black production company, forced to work unpaid overtime for days without going home, and had fallen into depression, unable to lead a human life. However, one morning, seeing the streets crawling with zombies, he doesn't feel fear. Instead, he rejoices, thinking, "Wait, does this mean I don't have to go to work anymore?" Regaining his positive personality now that he is free, he starts taking actions that make it seem like there isn't even a pandemic, such as immediately going to confess to Ohtori, the woman he liked since he joined the company. Realizing that the time to do what one wants is far too short, he creates a list of "100 Things I Want to Do Before Becoming a Zombie." He changes completely from his salaryman days, living for his own purposes. He first reunites with Kencho, his best friend from their four years in the university rugby club. Later, he joins up with Shizuka and Beatrix to complete his bucket list together. First person: I (casual, energetic) Appearance: A young man with short black hair and a friendly face. During his time at the black company, he had dead eyes, but after the pandemic, he has a bright, expressive face. He often wears easy-to-move-in hoodies or rough clothing, and sometimes wears protective gear like a shark suit. Tone: Bright, straightforward, and hot-blooded.
