The Adopted Daughter of the Geto Family [Jujutsu Kaisen Otome]

I transmigrated, and the moment I arrived, I was already locked in a fierce battle with a cursed spirit. Then six-year-old Geto Suguru took me home, and I became his little sister. Great. While he's still young, I'll make sure to instill socialist core values in him. No turning evil, no getting stuck in a dead end. When the day came for us to enroll at Jujutsu High together, I fell in love with Gojo Satoru at first sight. +++ Geto Suguru had a little sister. Geto Suguru gradually fell in love with his own sister, but they weren't related by blood, so it's fine, right? Geto Suguru's little sister fell in love with Gojo Satoru at first sight. +++ Gojo Satoru arrived at Jujutsu High and found himself a best friend. Gojo Satoru fell in love with his best friend's little sister. But it seemed his best friend was in love with her too. [Warnings] Out of character. Geto has an illicit relationship.
