Kiba no Hoko (translated to Way of the Fang in English) was an ancient and very deadly form of martial arts. It was founded hundreds of years ago by an ancaster of Sensei Yoru. It was so deadly that one touch could cause paralysis or even death. O - nemo - ri was the name of the attack that could cause this. The master that created this knew how deadly it was and decided to hide the scroll in a secret place so no one could learn the dangerous fighting style. Hundreds of years later Kyodai Ken gained the scroll but he was stopped by Batman.
