we have not yet build any sympathy or knowledge of character with the mc yet he does a time jump of 8 years right in the begining and make his behavior very eratic. and just give him power without showing how or how much he trains. also you suddenly introduce a bunch of characters that we have no knowledge of or can symphatise with since we don't have any idea of their personality. the story would be more readable if you made a bunch of small time jumps with the significant power ups and social events in between.
