My Sister the Heroine,
and I the Villainess
by Satou Mato（佐藤真登）
Editing: Nacht & other boytoys
Upon meeting the girl who would become her adopted younger sister, the duke’s daughter Christina regained memories of her previous life. Through those memories, she learned that her new sister, Mishuly, played the role of a heroine in a certain story.
And though the story depicted a Christina who abused her in the story, the real Christina turned into a siscon who spoiled Mishuly to no end.
Unfortunately, one day, Christina realised something. The best future for Mishuly lay on that story’s endings. And by following that story, whether it was execution, suicide, or exile, nothing fortunate would await Christina.
Even knowing this, Christina would not waver.
It was all for the sake of her sister.
This is a story about a siscon girl who ignored her own destiny, to bring happiness to her sister.
