Karate Shoukoushi Kohinata Minoru/YMMV


 * Fan Disservice: Minoru's fight scene with Kevin. Minoru, a Bishonen, being shirtless would normally be a pretty good thing. Except he's getting the crap beat out of him by an equally shirtless, insane and rather Gonkish Kevin.
 * Jerkass Woobie: Kevin Norton, once you learn his backstory.
 * Ruined FOREVER: The fact that Pedro, initially a villain, becomes part of the Karate club and his assasults are Played for Laughs, is a sticking point for more than a few readers.
