Her Sister (Code Realize Various x Fem Reader)

(Y/N) Beckford is Cardia and Finis's older sister. She doesn't possess the poison like Cardia, but she has an even bigger power that many are not aware of. What exactly is that power? What will this loving sister think when she is the center of many people's love as well? I do not own plot, characters, or pictures. Plot and characters belong to Otomate.
