I liked the beginning of kamen teacher. It was a good read at first and I was dieing for more, but then I got more... and I realized why the scanlators were being slow. The first part of Kamen teacher introduces us to a delinquent high school where the students have gotten completely out of hand. Araki Gota and kamen teacher are hired to deal with it as specialists. Well Araki sends all of his students to the gym and have a fight with "Kamen Teacher". Kamen Teacher drives around on a vespa and beats up all of the studentswith kick ass martial arts. Then he shaves them bald. I found this absolutely hilarious and I recommend you guys read it too.

Then it gets dull. All of a sudden kamen teacher wants to investigate what made the school rotten so he stops bullying his students, and starts talking to parents and such to find out what happened. I thought this was a betrayal of the reason I started reading the manga so I dropped it there.

My recommendation is simple, read the first 15 chapters maybe closer to 20 I don't remember, then drop the manga. When he starts his investigation it drops the comedy genre and goes into a slice of life genre... There was never much of a story to get into so you don't have to worry about getting hooked.
