The Little Sister- Spy X Family

Basically, the normal Spy X Family in which Y/N is the youngest Dezmond but was sent to the orphanage at birth due to a lifelong sickness she had, because the Dezmonds didn't want the public to know that they had a weak and sick daughter. But she gets adopted by Twilight as Anya's sister, and, like Anya, she developed a psychotic ability, but of teleportation.
