Meet Yoiyami Kuroha, a black-haired beauty blessed with luck. While most people would associate luck with happiness, it lead Kuroha down the path of despair. Seeing her luck as nothing but a curse, she gets captured in the underground world of the yakuza. As she struggles to escape her accursed luck, she meets a boy riddled with misfortune.

Note:
The "sequel" is just a slight title change as the series was originally intended to end at one volume. It follows up the events of this volume.
