I am thinking about starting USOGUI But I have some question/doubts about the story I will be grateful if someone can answer my questions.

  1. Is there any romance?
  2. Is it episodic or there are different arcs?
  3. Are there any good characters other than the mc?
  4. I have heard that the beggining of the series is lukewarm is there any specific point in the manga from where the story starts getting good or does it gets better gradually?

These are all the questions I want to ask . I know its a good manga , the reviews and ratings are overwhelmingly positive I just want to make sure that it suits my taste since there are more than 500 chs.
