Akira Tendo, a 24-year-old office worker of an extremely exploitative marketing firm, discovers himself trapped in a routine and meaningless life. He lacks drive and motivation after three years of abusive treatment; however, when a zombie apocalypse 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, depressing existence. He decides to create a bucket list of everything he wants to do before becoming a zombie in order to not only experience it firsthand but also to show that he is still alive and well. This decision gives him a newfound sense of purpose.
