Akira Tendo is a broken twenty-four-year-old corporate slave, utterly drained by his exploitative, soul-crushing advertising agency. Working relentless overtime under a tyrannical boss, he has lost all joy, passion, and ambition, resigning himself to a miserable daily grind. His bleak existence shatters overnight when a sudden
zombie apocalypse sweeps through Tokyo. Instead of panicking, Akira experiences a bizarre, euphoric sense of liberation; the outbreak means he no longer has to go to work.Realizing that society as he knew it is gone, Akira resolves to seize the day rather than merely survive. Inspired by a blank notebook, he drafts a "Bucket List of 100 Things to Do Before I Die," dedicated to reclaiming his humanity and living life to the fullest.His journey quickly introduces him to quirky companions who share his chaotic new reality. He reunites with his estranged college friend, Kenichiro "Keni" Ryuzaki, a former corporate executive who joins Akira to pursue his lifelong dream of becoming a comedian. Soon after, they cross paths with Shizuka Mikazuki, a hyper-pragmatic, risk-averse risk analyst obsessed with survival statistics. Initially appalled by Akira and Keni's reckless optimism and lack of survival preparation, Shizuka is gradually won over by Akira’s genuine selflessness and indomitable spirit, eventually completing the core trio.Together, the group embarks on a cross-country adventure across a delightfully absurd and dangerous post-apocalyptic Japan. Their exploits are driven by Akira’s wildly eclectic bucket list. They construct a makeshift RV complete with a big-screen TV, scuba dive in shark-infested waters using makeshift protective gear crafted from heavy-duty armor, and visit Akira's traditional hometown to reconnect with his anxious parents, whom Akira must save from a local cult operating in the disaster zone.Along the way, the characters confront their deepest personal traumas. Shizuka overcomes her emotionally abusive upbringing and learns to trust others, while Keni confronts his fear of failure. Akira proves that despite the horrific collapse of civilization,
human connection and personal fulfillment matter more than survival alone. The narrative balances high-octane action, slapstick comedy, and heartfelt emotional beats, illustrating that the true horror isn't the walking dead, but rather the modern cages we build for ourselves. Akira’s relentless pursuit of his dreams transforms him from a pathetic corporate zombie into a truly free individual, proving that even at the end of the world, it is never too late to start living.
