Heller was once a fighter ranked in single digits. He was not the strongest. The strongest was Israel, and then Riccardo was the second.
The Great Sword is a trap in the author's mind. He told us about the existence of the War Continent and then disappeared. How is this possible? Therefore, the author wants to complete War on the Continent and the Last Descendants of the Dragon on the basis of fitting the setting of the original work as closely as possible.
Heller is the fifth-ranked warrior in the male period, and is also a character who does not appear in the comics. He is used to complete some things that Yagi did not draw.
So there is yy, but the main plot in Big Sword cannot be tampered with, and the fate of the protagonists cannot be changed. This is the first principle.
