The night in Shibuya has become endless: lights flicker amid smoke and screams as the city crumbles under waves of cursed energy; in the midst of the chaos, a first-degree practitioner wanders through streets filled with rubble and shattered hope, unaware that within him beats a seed of latent dominion capable of distorting time in a moment of desperation; when a curse pierces his technique and everything slows down, a geometric pattern awakens behind his eyes, and the creature shatters like glass, leaving the practitioner exhausted and scarred, with a hidden power that is now a whisper, a promise, and a curse in the night that never ends.
