Genshin Impact: Nahida, God of Concepts

(A slice-of-life story at first, then a yandere story later.)

A lucky person chosen by the System becomes Nahida and is tasked with saving Sumeru.

After a great deal of effort, she succeeds in saving Sumeru.

Then she travels between two worlds with many people from Teyvat, exploring and having fun.

But why are the girls from Teyvat looking at her more and more strangely?
