Grail Knight

Rayan was an ordinary young man living a quiet, unremarkable life—until the day he was suddenly summoned by a mysterious witch to a strange, magical world. She told him the realm was on the brink of destruction, and though she meant to summon a great hero, fate chose Rayan instead.

Reluctant at first, Rayan soon discovered he had latent powers awakened by a magical crystal. With the help of unlikely allies—including a talking wolf—he faced monsters, dark sorcery, and a fallen hero who had once been summoned like him.
Through challenges and loss, Rayan grew into the role he never asked for. In the end, he defeated the darkness, restored peace, and chose to remain in the world he helped save—not as a summoned outsider, but as its true protector.
