Similar plot of haunted women who goes a lil bit crazy and both were intended to be "horror" movies, but since Koreans simply can't make horror, they ended up being good thrillers.

If you love school delinquents (and you know you do) fighting to reach the top for different reasons and finding meaningful friendships along the way, you'll love every Crows movie (based on very famous mangá series) just as much as KO One and the K.O. series.

Set on the same world of K.O. but not really a remake or side-story, K.O. One is a crazy school delinquent drama with tons of bizarre superpowers and even supernatural elements, and the three series are very fun to watch if you love school delinquent fighting for the top ranks and crazy stunts!

Though K.O. takes a (later) crazier approach on school fights and tons of bizarre unbelievable superpowers for the main delinquents, both series are very fun to watch if you love school delinquent fighting for the top ranks!

Both series are based on successful mangás of the same genre and have the same high spirits of delinquent students fighting to reach the top, each one for different reasons, and that leads to creating meaningful new friendships along the hard way.
