During the oath ceremony, a monster suddenly appeared and attacked Luca, and he was driven to the brink of death without being able to offer anything. At that moment, a sealed, forbidden flame was born within the boy. Will this vow and flame bring hope to the Knights, or will it become a new disaster? A full-scale dark battle fantasy begins as the forbidden flame burns! [Original Webtoon](https://manga.line.me/product/periodic?id=S153994)
