The beginning is kinda fun but somethings I found annoying many times during the story are:1. The MC is practically a country bumpkin even after around six months of arriving in Cregar2. He doesn't properly train his powers. He just uses the raw strength and speed he has without bothering with anything else3. The guy has an Uchiha complex. Like everytime he gets a power-up, he thinks he's the strong until something brutally breaks his pride into pieces(mostly his master)That's all I can think of, overall the story is pretty good for me
