Art might not be the greatest but it doesn't disappoint when needed. Overall a unique really complex and well written story, that'll make you wonder what decisions may be made after any regression, or if certain characters could be saved in the future. Good characters, interactions, and development. It's enjoyable, not that great, or ground breaking but still accomplishes it's goals. Start may be a bit slow, but seeing this character evolve and become stronger with the new knowledge he (And the reader) gains feels really good. You should really give it a try, you may actually end up liking it and binging 140 chapters at oncelike I did.
