Undead Unluck. Volume 8: 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.
Shen's obsession with avenging his sister's death at the hands of Feng nearly causes him to lose sight of himself until Andy reminds him his purpose is to protect the person right in front of him-Mui. During their battle, Feng launches a devastating attack, and Fuuko and Mui are his targets! Shen and Andy manage to block the attack in time, but not without paying a tremendous price. Now it's up to Mui to find a way to turn the tide in their favor!
