not sure what the author or writer planned to do with the rest of the story afterwards but how it played out it doesn't feel like much of any of it had any meaning in the end. Could have elongated the plotline for the first 5 chapters into one condensed story, but otherwise it feel like the chapter beyond serve to only draw it out.
My theory of this manga is somehow the animal human born then they manipulated human to accept them into society and their main goal is just eating human
