I've been laughing my ass off! seriously it's hilarious. Our main characters are really badass delinquents. There's the son of a yakuza and his number one enemy - tough but rather dumb Kuma. As I said it's a comedy, it's stuffed with jokes and funny situations. Don't take it seriously. To be honest the sense of humour is simple, so is the storyline and some of the characters... but somehow it works. Usually I can't stand this type of manga, dumb characters and simplicity just annoys me, but this one is just unique, it has something that makes me smile and relax.
In a way the plot is strong, the mangaka surely put some thought into it, there's something new in every chapter, many supporting characters and even some serious matters lay under the surface. There's growth of the characters, they have unique personalities and weird tastes, nothing is rushed. The idea of the whole universe that mangaka made is also interesting (and ridiculous but here's the charm). 2 volumes, long chapters but there's no room for boredom. I finished this manga in a blink of an eye. The only thing that repeats is hot graphic sex.
I like the art, it's expressive and messy, it suits the plot perfectly. I just love their glaring faces! Art is much better than the picture uploaded above so don't be mislead.
In short - I really had a good fun reading this stuff, so if you want to read something to cheer up, something light, funny and easy on the eyes go on and pick it up.
