After Shizuka is bitten by a zombie, Akira and the gang place their faith in the vaccine researcher Tsurumi. To save her, they will have to gamble on their trump card, Izuna, the girl immune to the infection. Later, a military-grade helicopter appears over the pharmaceutical plant that the gang is using as a vaccine lab and a special forces unit descends upon the building. What frightening secret could they be after?

After spending years slaving away for a soul-crushing company, Akira's life has lost its luster. But when a zombie apocalypse ravages his town, it gives him the push he needs to live for himself. Now Akira's on a mission to complete all 100 items on his bucket list before he...well, kicks the bucket.
