Review Detail of IslandFlare in World End: The Successor's Contract

I like the story the premise is great but the first few chapters need to be reread for grammar errors and there are times where a better use of word choice is best. Character’s are suddenly introduced and there are quite a few in the first few chapters. Interacts are great and fights are descriptive. But I can’t really visualize them well enough. The world had many things I want to know and would wish they were described in more detail. Possibly describe the village, city, buildings, ground, and air.
