Aku no Reijou to Juuni no Hitomi ~Saikyou Juusha-tachi to Densetsu no Akujo, Jinsei Nidome no Kareinaru Musouroku~

Lady Serena was betrayed by the crown prince, framed for a crime she didn't commit, and executed by poison. But instead of dying, she wakes up in the past with a second chance—and this time, she's not playing nice. After all, the so-called "murder" she was accused of was just a little misunderstanding! Looking back, Serena realizes her downfall wasn't due to poor scheming but a lack of competent underlings. Determined to rewrite her fate, she recruits a group of desperate orphans and puts them through ruthless training, forging them into the most lethal, fanatically loyal elite force the kingdom has ever seen. Armed with her deadly entourage and sharp wit, Serena is ready to crush anyone who stands in her way. In this thrilling, cutthroat adventure, a morally flexible villainess seizes her second chance—not for redemption, but for revenge. (Source: Seven Seas Entertainment)
