The story got only 2 points because it litteraly is without story... mostly. The storyline begins with a promise between 2 childhood friends when they were still at elementary school that when they get to highschool they will become heroes of justice! The rest of the story is random stuff like Gintama or Daily Lives of HIghschool Boys.
I loved the Art because it was so detailed and even the effects were nicely done. This mastered art made this manga more interesting to read since you could stare at the pictures even after finishing the text.
Each Character has different personality and each main charracter has a hidden side too which made them outshine other characters (well there are only those 3 :P). They'r mood can change in a blink of an eye and this benefits the story since it made the characters unpredictable and therefore you will never get bored of them.
Overall, Go read this, worth it and by the way figure out the way of reading before you go to next page (vertically from right to left).
