“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.

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. When the doors close behind him, the world he knew is gone.

Ryu arrives in Crescent Moon Academy, where forgotten souls linger, monsters pass as humans, and mysteries lurk everywhere. Worse? He’s fifteen years old again, in a body that isn’t quite his own.

As Ryu struggles to understand why he’s here, he’s left with an impossible question:

Is he chasing a ghost… or was he never real to begin with?
