Zero no Tsukaima - Volume 17 Chapter 9

Rules exist to be broken, and every loophole is a weapon. Trust no one, and annihilate those who deserve revenge.Granger Reiner never asked to be a champion, but fate chose him as the 101st contender for the goddess of Ascension—a deity mocked as the weakest among the pantheon, with 100 failed champions in just five months.Armed with a unique system and the ability to create barriers, Granger is thrust into Agrasia, a world teeming with treachery, to compete against other champions and conquer the Endless Dungeon.What he discovers is far worse than he could imagine: betrayal lurks at every corner, allies are fleeting, and the game is rigged.Learning the hard way that fairness has no place in a world built on lies, Granger transforms his weakness into his greatest strength. With vengeance as his driving force, he sets out to destroy the system, expose the truth, and turn the goddess’s mockery into triumph.In a world where everyone is an enemy, the 101st champion will stop at nothing—even if it means taking on the world itself.
