I honestly can't follow the logic of this manga.
The story itself is nicely written but it went from lighthearted training montage to heroic defender of justice to just psychologically fucked up kid who beats anyone and everyone half to death for fun way too quickly and it seems the author just...
After finishing the series on another website I can only say that towards the end it got more and more repetitive with a ridiculous amount of "SIKE" moments that really got old after a while.
First manga I ever followed from start to the end. Thanks so much to the scanlators and the original author. Loved every bit of it and its def a 9/10 for me.
