Aiko Kurozawa never believed in fate.
She believed in surviving.
a sudden, unexplained tragedy takes her parents, Aiko is left with no answers and no choice but to live under the roof of Risa, the cold and calculating woman who calls herself her sister. Aiko doesn't trust her. She doesn't trust anyone, really. Not since the funeral. Not since everything stopped making sense.
A week later, Aiko makes plans to run.
Instead, the sky fills with fireworks.
In the blink of an eye, the streets of Tokyo fall silent. The crowds vanish. The world empties. And Aiko wakes up in a version of the city that isn't hers where survival means clearing deadly games, and losing means disappearing for good. With only Heiya by her side, Aiko is thrown into the Borderlands, where trust can kill, emotions are weapons, and every heartbeat could be your last.
She didn't ask for this world but her goal is to escape.
