Sword Saint Story: Starting From Zero Attack Power ~After Being Abandoned by My Childhood Friend, the Princess, I Enrolls in a Magic School and Ends up Making a Contract With the Demon Lord~ (LN)

Wielding the Ultimate Swordsmanship and the Power of the Demon Lord

Born into a prestigious family of swordsmen, Eugene was branded a “defective swordsman”—his defense was unmatched, but he lacked any offensive power. Leaving his homeland behind, he enrolls in the continent’s most renowned magical academy.

There, Eugene is recognized as the only one immune to the miasma of the Sealed Prison, a dungeon teeming with mythical creatures. Tasked with reaching its very depths—a feat that even the most seasoned archmages have failed to accomplish—he ventures into the abyss.

At the very bottom, he encounters the legendary Demon Lord Erynyes, who once ruled over the continent. To his surprise, Eugene is the only one capable of forging a contract with her…!

Armed with the power of the Demon Lord, the once-failed swordsman embarks on a journey to become the strongest Sword Saint in this epic fantasy adventure!
