Writing Quality: Might want to rewrite chapters, but its alright
Stability of Updates: Nice! Maybe its because the author just started, but the updates are chapters every day or two.
Story Development: Well made and is quite interesting and entertaining, especially the conversation between the two people. Just need to fix the grammar part to be good.
Character Design: MC is very straightforward and at the same time the one who thinks before he acts
World Background: Not quite sure about this one, but things who have been better if things are explained a bit, like levels, techniques, and how the new world works and such. For the most part, its alright.
