Akira Tendo, a 24-year-old office worker of ZLM, discovers himself trapped in a routine and meaningless life. He lacks drive and motivation since he is disenchanted with his career; however, when a zombie apocalypse caused by experimental bio weaponry unexpectedly strikes Tokyo, everything is turned upside down. Instead of succumbing to dread, Akira sees this as an opportunity to experience life to the fullest rather than settle for his humdrum existence. He decides to create a bucket list of everything he wants to do before dying in order to not only experience it firsthand but also to show that he is still alive and well. This decision is made with a newfound sense of purpose.
With the happy company of his friend, Kencho, Akira embarks on a number of exciting and frequently bizarre excursions throughout the zombie-infested city. Their pranks range from simple pleasures like eating at expensive restaurants for free to more extravagant pursuits like going on roller coasters and visiting haunted houses. Akira and Kencho come across other survivors who have their own motivations for surviving as they make their way through the dangerous streets swarming with flesh-eating zombies. Along the journey, they forge odd alliances, face their own anxieties, and learn the importance of friendship and the human spirit’s ability to persevere in the face of difficulty.
