Tsuihou Sareta Tensei Juukishi wa Game Chishiki de Musou Suru

In a world where one's fate is decided by a divine ritual, Elymas, the son of a legendary swordsman, is cast out when he receives the scorned class of Heavy Knight. Branded a failure and exiled, he carries a secret: his memories of a past life where this world was a game. In that game, the Heavy Knight was the ultimate class.

This anime follows Elymas's journey as he uses his game knowledge to master his supposedly defective abilities. Defying expectations, he turns a class meant for cowards into an instrument of incredible power, challenging the very system that rejected him.
