I am Möbius's sister.

In the pre-Honkai era, I was Mébius's younger sister, named Sirin. Although we weren't blood-related, we were closer than blood-related sisters. My older sister was very good to me and often gave me delicious food.
Until one day, I unwittingly awakened the Herrscher's abilities and even received a belated cheat code.
From then on, the way they looked at me became increasingly strange. And the world became increasingly strange too. "Alicia, save me! My sister's going to make me do experiments again!"
