Leon, a former Japanese worker, was reincarnated into an “otome game” world, and despaired at how it was a world where females hold dominance over males. It was as if men were just livestock that served as stepping stones for females in this world. The only exceptions were the game’s romantic targets, a group of handsome men led by the crown prince.

In these bizarre circumstances, Leon held one weapon: his knowledge from his previous world, where his brazen sister had forced him to complete this game. Leon, who really just wants to to live as a shut-in in the countryside, uses that knowledge to raise a ferocious revolt against the women and handsome men.

Combining reality with a gaming world where ferocious beasts roam freely, filled with numerous mysteries and dungeons. In order to defend against the onslaught of these beasts, everyone undergoes class transfers and crazily levels up. On the day of his transfer, Lu Fan becomes a hidden class – Dragon Tamer.

Fortunately, he awakens the Super Treasure Map System. As Lu Fan, with his mighty dragon, sweeps through everything, the entire world trembles.
