Touka Mimura is an ordinary, unpopular Japanese high school student who, alongside his entire class, is suddenly summoned to a
fantasy world by the arrogant Goddess Vicius. Tasked with becoming heroes to defeat the Evil Goddess of Despair, the students are evaluated based on their innate gift ranks. While his classmates receive powerful classes like Swordsman, Mage, and Paladin, Touka is branded a worthless "Abnormal" with an E-rank skill called "Paralyze." Viewing him as completely useless and a waste of resources, Vicius banishes Touka to the Disposal Ruins—a deadly abyss teeming with ravenous, high-level monsters designed to ensure his gruesome and immediate death.Left for dead in the pitch-black labyrinth, Touka is driven by an overwhelming, consuming desire for revenge against the Goddess and the classmates who abandoned him without a second thought. Instead of succumbing to despair, he uses his seemingly pathetic paralyzing magic in creative and ruthless ways. He discovers that his low-level spells, when chained strategically, can completely neutralize even the most ferocious monsters, turning his weakness into an invincible combat system. Through sheer grit, strategic cunning, and relentless training amidst the abyss's horrors, Touka slaughters countless beasts, rapidly leveling up and surviving against impossible mathematical odds.Upon finally escaping the ruins, Touka adopts a hardened, cynical persona and conceals his identity behind a menacing iron mask, calling himself "Egoist." His primary motivation shifts from simple survival to a meticulous long-term campaign of vengeance. Along his journey through the empire, he rescues a traumatized, beast-woman slave named Seras Ashrain, a former knight seeking her own retribution. Forming a powerful alliance based on mutual trust and shared grief, the duo navigates treacherous political landscapes, outwits the Goddess’s zealous holy knights, and uncovers the dark, manipulative underbelly of the kingdom that summoned them.Touka’s incredible journey transforms him from a bullied outcast into an apex predator who wields his low-level spells with terrifying God-like efficiency. As he systematically dismantles the obstacles in his path, he edges closer to his ultimate
confrontation with Vicius. Throughout the unfolding chaos, Touka remains coldly focused on his singular goal: to tear down the arrogant hierarchy of the gods and make everyone who wronged him pay the ultimate price. His ruthless evolution redefines the very limits of magic in a world that cast him aside, proving that even the lowest-ranked spell can annihilate creation itself.
