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.

Sick of being targeted, Fuuko and Andy decide they would rather be the hunters than the hunted. So they set their sights on joining the ten-member Union. But to snag the second seat they need, they'll have to defeat their would-be assailant, Unchange!
