Synopsis
After losing her life in an accident, Emi is reincarnated as a young noble girl named Remilia Rose Graupner.
Remilia is the most feared villainess in a certain otome game, and Emi’s beloved “fave”.
Moved by the loneliness that once left the original Remilia with nothing but resentment toward the world, Emi resolves to make her happy with her own hands. Through tireless effort and her natural kindness, she gradually brings to those around her.
However, the game’s “original” heroine will not allow it.
“I’m sorry I couldn’t make you happy… Remilia… -tan…”
Betrayed by those she trusted and unable to escape the game’s inevitable condemnation event, Emi—within Remilia—loses consciousness in the depths of despair.
But at that moment—.
“I will never forgive you.”
Rising with a quiet fury is Remilia, who has regained control of her body for the first time in 11 years.
Having first learned the meaning of “love” through Emi’s kindness and having watched Emi struggle tirelessly for her sake, Remilia now vows revenge against those who hurt her.
The curtain rises on a fierce and elegant revenge drama, led by the "true" villainess herself.
“Everything is for the sake of the world (you) I love—.”
Within the Villainess will premiere in 2027
