Leon is a hardworking but seemingly talentless student at the Royal Academy who suffers from a massive inferiority complex toward his brilliant rival, the crown prince. Despite his struggles, Leon's unwavering righteousness unexpectedly earns him the loyalty of the Holy Sword Elcid—a legendary, sentient weapon originally fated for the prince. Armed with the overpowered sword, Leon must undergo grueling, brutal training to genuinely earn his new strength rather than cheesing his way through battles. Alongside his new party members, he sets out to prove himself as a true hero and save the world from a great evil. Written by McEnroe.
