Kuroha Yoitsuji is known for having great luck but it seems like her fortune spreads to those around her. She was orphaned at a young age and is cared for by the leader of the Yakuza group "Hibauchi," who uses her as a weapon against his enemies. Feeling guilty about causing misfortune to others, Kuroha throws herself out of a window in desperation. However, before hitting the ground, she is rescued by Nijisuke Murokawa. Despite being the victim of numerous accidents in his life, Nijisuke refuses to believe in luck, attributing all events to mere coincidences. His strength serves as an inspiration to Kuroha as she tries to leave the city with Nijisuke and his companion Hokuto. She wonders if her savior is truly strong or if she is weak, and whether she can take control of her own fate and stop being used as a tool by others.
