Shun Imai

Shun Imai is a 24-year-old who works shifts at a nightclub while passionately supporting his favorite idol, Rui Nikaido of 'Mysterious Kiss.' His life takes a dramatic turn when, during an ordinary taxi ride, he casually asks driver Kotokawa for a lucky number — a spontaneous question that leads him to win a staggering one billion yen jackpot. Despite his newfound wealth, Shun remains humble and grounded, continuing to cheer for his idol as always. However, the enormous sum draws the attention of dangerous criminal organizations, pulling him into a web of threats and underworld schemes he never anticipated.
