Schema, a sentient artificial intelligence, has transformed Earth into a structured game-like system where every human wields status screens, acquired powers, and unique abilities. What appears as humanity's greatest gift—the chance to grow stronger through leveling—becomes an intoxicating escape for most. But for Daniel, this new reality is far more sinister. Interdimensional rifts tear through reality, releasing nightmarish creatures from the abyss into the world. Schema converts these breaches into dungeons, turning catastrophic invasions into organized battlefields where humanity can mount a defense. Trapped within one such dungeon, Daniel uncovers a haunting truth: escape demands a price only he can pay. As mystery deepens and survival hangs by a thread, Daniel must navigate a system designed to empower—or consume him.
