Here is a mixed rules fight between karate fighter Katsunori Kikuno and Yuichiro Nagashima which took place in the Dream organizations "Fight For Japan: Genki Desu Ka! New Year! 2011," event at the Saitama Super Arena, Saitama, Japan, on 12/31/11.
The first round was fought under K-1 kickboxing rules while the second was under Dream's MMA rules. As you will see, it was a pretty crazy scrap.
