Tsuihou sareta Tensei Juukishi wa Game Chishiki de Musou suru

Born into a prestigious family of master swordsmen, Elymas Edvaughn’s future shatters when he awakens the so-called “defective” Heavy Knight class. Disowned and cast out, he regains memories of another life—and realizes this world mirrors a VR game he once mastered. Armed with knowledge no one else possesses, he sets out to rewrite his fate and prove the strength of the “weakest” class. (Source: Crunchyroll)
