In order to master the mystery of Prince Navel's swordsmanship, Lagarde tried every means to get close to Navel and him to compete swordsmanship. They became closer to friendship in their relationship. When Navel was in danger, Lagarde stepped forward. Navel was so moved that he awarded Lagarde the title of knighthood and taught him the mysteries of swordsmanship. Count Gonzag, the Duke of Navel's cousin, is the sole heir to Navel's property. But the world is unpredictable. Navel fell in love with the Baron's daughter Blanche and gave birth to his daughter Auror, which caused Gonzag to lose his inheritance. Gonzag ruthlessly killed Navel, who entrusted his daughter to his friend the Knight of Lagarde before he died. Sixteen years later, the knights of Lagarde painstakingly brought up Aurore, not only recapturing the huge fortune seized by Gonzag, but also avenging Navel.
