Review Detail of CRA112 in Reincarnated with Fairy Tail System! (DxD)

I personally enjoy this because the system gives pretty much 0 help or guidance so mc has to figure everything out himself though I would like to get a more in-depth look into the laws/rules the supernatural council has for example when the devils take a city and or town are the native supernatural creatures who lived there allowed to stay or will they be kicked out of said town But what is the update schedule??
