“Imagine falling in love with someone who was never supposed to exist.Now imagine waking up and realizing you weren’t supposed to exist either.” Ryu Takeda’s life was ordinary—until fifteen minutes went missing. One moment, he was standing in a parking lot; the next, he was mid-conversation with a mischievous girl named Lana—a girl he has no memory of meeting. A girl who seems to know everything about him. And then, reality shifts. Before Ryu can question what’s happening, Lana vanishes, leaving only a cryptic warning… and a school bus waiting for him. A school bus that shouldn’t be there. Against all logic, he boards it—and when the doors close behind him, the world he knew is gone. Ryu wakes up in Crescent Moon Academy, a school trapped between life and death, where forgotten souls linger and time doesn’t flow the way it should. Worse? He’s fifteen years old again, in a body that isn’t quite his own. The only clue to his past—and his future—is a girl who died decades before Ryu was even born. As Ryu struggles to understand why he’s here and why reality is unraveling around him, he’s left with an impossible question: Is he chasing a ghost… or was he never real to begin with?
