I didn't really know what to expect from the manga, and especially its main character.
The story itself is your typical shounen story with the villains that escalate in power with a modern delinquent aesthetic. Its the case where the characters make the story as an experience better than it actually is.
Hayato is probably the most endearing loud mouths I've seen in a while. He's very much a thug, but you can tell he means well and will do anything to fix his errors and is very considerate about how others feel. His interactions with the various characters are dynamic and especially entertaining.
The art is very well done. I just have a love for the quasi-realistic style for this story. The designs are pretty damn diverse in terms of fashion like cornrows, mohawks, dread locks, dyed hair, afros and the like.
One of its downfalls is that the female characters aren't as detailed as the male characters and suffer the most from the dreaded "same face syndrome" which unfortunately affect some of the male characters near the last quarter of the manga's run. There was a weird point of the manga where the backgrounds are clearly black & white photos which is nothing shy of off putting to me.
The action is pretty disappointing. There wasn't any real choreography for most of the fights. Just a war of attrition of punches, kicks, an occasion back kick or headbutt. I know these are street fights but you can be a lot more creative where the environment is practically a weapon. And there's a weird trend where most of the thugs' main choice of weaponry is a police baton.
The story is rather simple and easy to follow, but it gets really repetitive near the end from the story beats to the dialogue. It probably knew it was losing steam and ended which has my respect because there wasn't much left to show off without turning into a broken record like some shounen tend to be.
This is a good shounen manga worth your time for the characters and how they bounce off each other.
