The manga follows the infamous villainess Doronjo, the charismatic leader of the Dorombo Gang from the classic Time Bokan franchise and the arch-rival of the superhero Yatterman. After suffering a defeat at the hands of the Yatterman, Doronjo and her loyal but bumbling henchmen, Boyacky and Tonzura, suddenly awaken to find themselves transported to an unfamiliar fantasy world. Undeterred by this strange new environment or the chance for reform, Doronjo remains true to her nature. Rather than seeking redemption, she enthusiastically embraces her identity as a villainess and sets her sights on a new goal: to conquer this new realm and make the name of the Dorombo Gang feared once more.

The central conflict arises from the clash between Doronjos old-school, theatrical villainy and the conventions of a typical fantasy world. The narrative arc follows the gangs misadventures as they attempt to establish their criminal empire from scratch, likely encountering the worlds heroes, magical creatures, and political structures. The story is a comedic take on both the isekai and villainess genres, using Doronjos unapologetically wicked personality as the driving force. The manga began serialization in January 2024 on Mag Gardens web manga site MAGKAN and concluded its run in August 2025, with its chapters compiled into two volumes.
