Setup has always been there, but it's always changing. I think it's more important to set it for the author to read than to let the reader understand. I'm not a big fan of having a whole bunch of styles at the beginning. Ai Xue and Zero have never seen much of the world, and their strength is also very weak, and many things need to be seen with their own eyes and heard with their ears.

I'll admit that the transition in the first volume is a bit too long, and the main character is too soy sauce. But it will be different soon, so stay tuned!
