Immortal Victor

/(Weak) Aaron Voss, a cavalryman who lived a hard life in his previous life, died in the last battle with the kingdom. He still has no fear in the face of a warrior a hundred times more powerful than him, even though he is not as good as the opponent by a hair. But There is no doubt that he died, and at the end his desire for power was recognized and a new existence began. Reincarnated Warrior, Sieger (Okay, you can ignore the work tag)
