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.

Having been caught in a compromising position with another girl, Akira wants nothing more than to clear the air with Shizuka. But when zombies break free of the hold of their boat, the two of them fall overboard and are washed up on a deserted island. Akira is excited for the chance to knock another item off the bucket list, while Shizuka is anything but. Could this rough patch lead to a heartfelt discovery?
