The Defective Who Controls Mana

Leon Ashen grew up knowing how cruel the world could be. After his mother was taken by the state and his family name erased, the academy was supposed to be his only chance to survive in a society ruled by mana. But when the evaluation came, Leon received the worst verdict possible—Defective, a human born without a mana core, destined to live as nothing more than disposable labor. Yet Leon carries a secret no one can know. Though he lacks a core, he discovered a forbidden way to manipulate mana through his own blood—a power that floods his mind with the emotions of others every time he uses it. When monsters and horrors descend upon the academy, Leon must decide how long he can remain a powerless Defective… before revealing the dangerous truth that could change everything.
