From the Sekai to Teyvat

For eons, Asmoday-the Ruler of Space and Time-has watched the script of Teyvat play out. But after countless resets, she faces a terrifying truth: the Traveler alone is not enough. The Abyss inevitably swallows the Throne, and the story always ends in ruin.

Desperate to save her world, she breaks the one rule: she reaches across the Void for external help.

She finds a digital universe governed by song. She finds Her.

A deal is struck with the Administrator of the Sekais. Four souls are stolen from their reality to become the new variables Teyvat desperately needs to break the cycle:

The Unifier (Ichika Hoshino)
The Star (Tsukasa Tenma)
The Idol (Haruka Kiritani)
The Void (Mafuyu Asahina)

But Celestial Miku is not a benevolent god. She demands a tax for her assistance. For every light sent to save Teyvat, a shadow must be cast to ensure the game remains... entertaining.
While four heroes fall into the wind to save the world, one soul is sent to the Abyss to burn.
The stage is set. The actors are in place. But can they rewrite a script written by Gods?
