Firstly, the story is interesting and we feel the author put a lot of efforts to create a complex and complete world. The characters are not yet well developped, BUT this is because there is not yet enough material to do so (only 16 chapters at the moment), and we can see there will be character developments soon in the future. The MC is OP but restricted with the use of his power, which will give a good development of the story.
Secondly, the author has a good writing, english is not my first language but I can see there is not (or very little) gramatical/spelling/conjugation error.
So I really recommend to read this story if this is the kind you like (of course everyone has their own tastes)
