Diabolo

Ren and Rai are drawn into a dark and mysterious world when they encounter the enigmatic Diabolo—a being whose true nature remains shrouded in secrecy. At the center of their story is a desperate attempt to protect someone precious to them, setting them on a collision course with forces beyond their understanding. As the Diabolo begins making tempting offers to students at their school, Ren and Rai find themselves caught in a web of supernatural bargains and sinister consequences. Each deal comes with a hidden price, and as their 18th birthdays approach, the true cost of these pacts threatens to unravel everything they hold dear.
