I, Sister of Mebius

In the pre-collapse era, it was Mebius' younger sister, named Sirin.Although she is not a real sister, she is closer than her own sister.My sister is very kind to me and often gives me delicious food.
Until one day, I awakened the Herrscher's ability in a confused way, and also got a belated golden finger.
The way they looked at me became more and more strange.The world is getting weirder. "Alicia save me! My sister wants me to experiment again!"!
