Review Detail of Semyasa in My Vampire System

from the 70-ish chapters I've read, the story is alright. The characters are ok, with only one of them being remotely interesting. the writing is slightly sub-par, as I seem to find mistakes in almost every single chapter... There is a definite need for a proof-reader. As for the world's background, the general Idea is there, but I feel it is too ambitious for the level of the author's writing. What attracts most readers I believe is the simply the concept of the story, and with the story being ok, it looks like a recipe for succes.
