I Transmigrated into Zygarde, and This Is Teyvat?

“Hello, everyone. I’m the Zygarde Core. That’s right, the core of Zygarde, the God of Order. But there’s one big difference between my core and the original: when necessary, I can pilot a Gundam all by myself.

I had just transmigrated and was planning to go find Ash, but then I realized I’d ended up in the hands of a blonde girl. Turns out this is Teyvat.”
