So far with 9 chapters, the pace is incredibly fast. There's already been three fights, and a tournament arc going on. I would complain, if the characters were interesting. They're all so bland, and so far the only goal expressed is getting stronger.
With that being the case, the fast pace is actually helpful in keeping this engaging. Don't know how long that is going to last, as the writer needs to either make the characters have a personality or make the choreography of the fights varied.
