Synopsis
Eugene was born into a prestigious swordsman family and branded defective — impenetrable defense, zero attack power. He enrolled in the continent's top magical academy and was identified as the only person immune to the miasma of the Sealed Prison, a dungeon that even archmages couldn't clear. He ventured to the bottom and found the Demon Lord Erynyes, sealed and legendary — and discovered he was the only one who could contract with her. Armed with her power, the failed swordsman set out to become the strongest Sword Saint alive.
