Black Black Lotus

After transferring to Fuyou Girls School, Renna crosses paths with Kyouko, an enigmatic and beautiful student revered by her peers as the "Black Rose." To Renna's surprise, Kyouko seems to know her intimately, confessing that it was Renna's captivating voice that drew her in years ago—so much so that she intervened to save Renna during their elementary school days. This revelation shatters a mental barrier within Renna, forcing her to confront a deeply buried trauma: the true reason she was forced to relocate to a remote town four years prior, a memory she had suppressed entirely for her own psychological survival. The fragile peace of Renna's new life collapses when she discovers a devastating truth—the Black Rose is dead, having been murdered on the very day they were supposed to reunite. Overwhelmed by grief and guilt, Renna's nightmare deepens when she receives a mysterious black card inviting her to "Black Black Lotus," a clandestine website dedicated to arranging murders. As she navigates this dark underworld, Renna uncovers a horrifying revelation: someone using her name is responsible for killing Kyouko. Now, she must unravel the identity of this imposter before the deadly game consumes her as well.
