Undead Unluck, Vol. 11 by Yoshifumi Tozuka

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.

Fuuko has finally reached the top of the tower and has been plunged straight into a three-round competition with the fate of everyone at stake! The score is tied as she heads into the final bout. But just before the third and final game begins, God’s brainwashing drives Spring to enter his ultimate form!
