I Parry Everything

Ore wa Subete wo "Parry" suru: Gyaku Kanchigai no Sekai Saikyou wa Boukensha ni Naritai

Having freshly arrived at the royal capital after over a decade of rigorous, isolated training at his mountain home, Noor's dead set on achieving his childhood dream of becoming an adventurer, even if the only skills he possesses are useless ones. Sure, he can "Parry" thousands of swords in the span of a single breath, but everybody knows you need more than that if you want to be an adventurer! Our hero's road to making his dream come true will be long(?) and arduous(?)—but if there's one thing Noor's not afraid of, it's some good ol' fashioned hard work! (Source: J-Novel Club)
