Hajime no Ippo, Katekyo Hitman Reborn! Recommendations
You my think how are these two similar one has to due with boxing and extreme workout while the other also has to due with training but this one has powers. Well Hajime no Ippo and Katekyo Hitman Reborn are alike. Both main characters start as wimps like they are no good. The main characters work there way up from being weak to being strong and they never give up. They both go through extreme training and they may complain but in the end when they are in a tough spot they out of the blue find a way to win. Both are long running
Both main characters have a big way from "crying boy" to "Man!" .
