"Hello everyone, I am the Core of Zygarde. Yes, I am the core of Zygarde, the God of Order. However, the biggest difference between my core and the original work is that I can drive Gundam alone when necessary. I just crossed over and planned to find Xiaozhi, but I found myself in the hands of a yellow-haired girl. It turns out that this is Teyvat."
