Erin Lisus was a villainess by reputation alone — publicly shamed, her life crushed by her stepmother's lies and abuse. After being killed, she reincarnates into two different worlds, living two full lives: one as a modern ordinary person, and another as a genius swordmaster. Now she's back in her original body before the worst of her suffering began, armed with skills and knowledge from both those lives. At Atenz Academy, everyone is shocked when the pampered noble suddenly moves like a top-tier warrior. But Erin isn't out to prove anything to her bullies. She has specific people to protect this time, and a stepmother who doesn't realize her prey just leveled up across multiple lifetimes.

The official synopsis mentions the regression, but what it doesn't tell you is that the storytelling is unusually structured: Erin has lived three distinct lives in total, not two. Her first life was the tragic original. The second (a modern-world detour) and third (as a swordmaster) both feed into her current timeline. This gives her a wider tactical and emotional range than most regression leads. The tone leans toward serious revenge drama with sword-fighting action, though romance readers will appreciate Second Prince Ferdin — a cursed man who can see truth, and who sees right through her villainess mask. The art is clean, the fight choreography solid, and the emotional beats hit hard. For fans of I Tamed My Ex-Husband's Mad Dog or The Villainess Lives Again, this one scratches the same itch of a calculating, deadly FL with nothing left to lose.
