KO One (2005)

It's the first of the series. You understand the story universe and characters better if you start with this one first.

IT'S better to watch it in order the X family is the 2nd season of KO ONE and then after watch KO3 an GUO it makes you understand the series much better.

Both are overtly comedic in their take on high school thugs and tough guys, and you can't help but love each and every unique character.

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!

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.
