Saijaku Shoku ga Zense no Chishiki de Sekai Saikyou

In a world where magic has withered into a shadow of its former glory, the legendary wizard Roy meets his end—only to open his eyes once more as Yuug, a young boy born into a future that has all but forgotten the arcane arts. What was once the pinnacle of power is now dismissed as a relic, and those who wield it are scorned as the weakest class in society. But Yuug is no ordinary mage; cradled within his youthful mind is the accumulated wisdom of his previous life, centuries of spellcraft and esoteric knowledge that the modern age has lost to time. Armed with this forbidden repository of ancient techniques and his own unparalleled raw talent, Yuug finds himself trapped between two worlds: the frail expectations of a society that sees him as worthless, and the staggering potential that only he knows he possesses. As he navigates the perils of his second childhood, every incantation and whispered chant draws him closer to the truth behind magic's decline. Determined to shatter the prejudices that confine him, Yuug sets out on a daring adventure to carve his own destiny—proving that the so-called weakest class may just hold the keys to reshaping the world itself.
