What happens when an unlucky girl meets an undead guy? Pure chaos! 
Tired of inadvertently killing people with her special ability Unluck, Fuuko Izumo sets out to end it all. But when she meets Andy, a man who longs for death but can't die, she finds a reason to live--and he finds someone capable of giving him the death he's been longing for. 
Andy and the others head off to rescue Fuuko and slay Spring. Amidst a fierce battle between the Union and Under, Fuuko reaches the top of the tower alone. There, she tries to talk things out with Spring, but the UMA, bound by the will of God, challenges her to a three-round competition to decide the fate of the world!
