There is a place after death that’s neither heaven nor hell. A bar that serves you one chance to win. You cannot leave until the game is over, and when it is, your life may be too.

16-year-old super-studier Nagi Umino, second-year student at the Megurogawa Academy high school, was switched at birth. On his way to a dinner to meet his birth parents, he accidentally meets the brash, outspoken, Erika Amano, who is determined to make Nagi her fake boyfriend as she never wants to actually marry. But once Nagi makes it to dinner, he finds his parents have decided to resolve the hospital switch by conveniently having him marry the daughter his birth parents raised...who turns out to be none other than Erika herself!

As an unexpected typhoon bears down on a small tropical island, a group of students trapped at school find themselves forced to put aside their personal issues and work together. Not only to save themselves, but possibly the lives of everyone on the planet!
