**Fia**, a girl who aims to be a knight despite being told she 'has no sword talent.' On the brink of death, she suddenly recalls her past life as the **'Great Saint'** with extraordinary cheat-level power.
The Great Saint's power revives too — but Fia remembers being threatened by the Demon Lord's right hand in her past life: 'If you're reborn as a saint, I'll kill you.' So she resolves to **hide** that power and live as a knight.
Aiming to be a knight while concealing the strongest power — an 'identity-hiding' fantasy where nail-biting suspense and exhilaration coexist. Airing from October 2026.
