A dead-eyed 24-year-old stares at a zombie flick through the morning-after haze of another all-nighter at an exploitative marketing firm. Akira Tendo has clocked three years of soul-crushing overtime, unpaid wages, and a boss who uses his self-esteem as a punching bag. Even his office crush, Saori Ohtori, barely registers his existence. The apartment is a landfill of takeout containers and crushed beer cans, and Akira shuffles through it like one of the undead he's watching on screen—functional but completely hollow inside .

Then his landlord starts eating another tenant for lunch, and the entire city of Tokyo unravels into a feeding frenzy. Zombies swarm the streets, society collapses in the space of a single commute, and Akira Tendo—doormat, corporate drone, man who couldn't even mumble a confession to the accounting department—stands on a rooftop and screams something that changes everything: he never has to go to work again . The suffocating weight of his old life evaporates, replaced by a manic, technicolor clarity. Before he becomes a zombie, he will live. Really live. He scrawls a list of 100 things he's always wanted to do: clean his damn room, ride a motorcycle, give free hugs, become a superhero, travel Japan from coast to coast . Joined by his thrill-seeking college buddy Kencho and the razor-sharp survivor Shizuka, Akira tears across a zombie-infested Japan checking off dreams between near-death encounters. The question isn't whether the zombies will catch him. It's whether a man who spent years dead inside can cram a lifetime of joy into the apocalypse before the clock runs out.
