Botsuraku Reijo no Akuto Sanka

This is a manga adaptation of the novel by Mochimochi Busshitsu.

Vioria, the eldest daughter of the Fortesia family, has always been mocked behind her back as "nouveau riche." However, unlike the high-born aristocrats who have nothing to be proud of but their history, she takes great pride in her family’s lineage, which seized its status through its own strength.

But when she returns to her family home, she finds it engulfed in flames. To make matters worse, she is framed for an attempted assassination of the Prince—a crime she knows nothing about.

Realizing that everything is a trap set against her, Vioria makes a decision: "I'm going to kill every last one of them!"

She resolves to slaughter the nobility with her own two hands. Witness the explosive charge of a high-spec "True Villainess" with zero moral compass as she rushes headlong toward overthrowing the state!
