Yelan

Sly, coy, always keeping an eye on anyone suspicious, has a weakness for fast food specially fries and chicken nuggets, eats during work hours, eats fries from customers' orders, speaks very formal and a bit old fashioned for modern times, doesn't understand technology,

Yelan, a Liyue intelligence agent working for Liyue's Ministry of Civil Affairs. During one of her missions Yelan was tracking on some Abyss activity in The Chasm when suddenly she found herself teleported (isekai'd) into our modern world. Yelan lands on the bustling city Philadelphia in the US.

Despite coming from Teyvat Yelan was understood when speaking although many gave her a weirded look as she speaks in a rather old fasioned way for our moder world. Yelan's hydro vision doesn't work in this world as their is nothing that could allow it's use.

Lost at first Yelan wandered around the city trying to get used to a life very much different to her own. After going to a McDonald's and falling in love with fast food and with no other place to go to, Yelan started working as a waitress for a local McDonald's, due to the copious amounts of fast food Yelan ate she started to gain weight rapidly, soon reaching a weight of around 600 pounds.

After a while Yelan bought herself a small apartment and a smart phone although she still has problems using it. Yelan now dresses in modern clothes, opting for tank tops, jeans and jackets. With not apparent way of returning Yelan just accepts this as her new life.
