The Scarlet Reversal System

When the Cataclysm descended, turning cities into monster-ridden ruins and granting humanity a brutal System, Yamada Toyoko, a quiet college student, awakened a seemingly useless ability: 'Scarlet Reversal'. It grants her the power to transform any disadvantage, curse, or even her own wounds into a potent, temporary boon. Haunted by the memory of failing to protect her younger brother years ago, Toyoko is initially hesitant to brave the monster-infested streets. But as the System's true, predatory nature unfolds, threatening to enslave what's left of humanity, Toyoko finds herself at the heart of a desperate struggle. She must master her unpredictable power and confront the monstrous forces, both human and otherworldly, that seek to dominate this shattered world, all while battling her own inner demons of guilt and inadequacy.
