The world had changed when the System arrived, alongside the Cataclysm that filled the world with monsters. The technology was gone, replaced by classes and skills that allowed the people to fight back. When Devon ended up as a Blacksmith, a class that didn’t grant Intelligence, he had to face the reality, that his old career that he loved - mathematical sociologist - was over. Instead, he had ended up as yet another discarded member of the production class, overshadowed by the existence of the System Shops to the point of total marginalization. But, what if all he needed was to reapply his scientific thinking to the System...

The protagonist is reborn in the world of the game he loved so much – [Dungeon Brave Souls]. However, he was reborn not as a hero who adventures with the heroine while flirting with her, but as a villain who steals the heroine and drives the world to extinction.

Why in the world should he be reborn as a villain who ruined his favorite game? The protagonist is in despair, but he still decides to live his second life freely, using his knowledge of the game. However, the reality is not as good as he expected. Events that should not have happened in the game, scenario changes happen one after another…!

The villainous character crushes both the demon king and the heroes. A heroic tale of evil supremacy!
