I, Mobius's Younger Sister

I live in the Previous Era of Honkai. I'm Mobius's younger sister, named Sirin.

We're not blood sisters, but we're closer than if we were.

Big sister treats me very well and often gives me delicious food.

Then one day, I somehow awakened the power of a Herrscher and received a late golden finger.

From then on, their looks at me grew stranger and stranger.

This world also grew stranger and stranger.

"Elysia, save me! Big sister wants me to be a test subject again!"
