The Karate Wars Part One; In Japan, Ikano begins disciplining his wayward grandson, Kono; In The City, as Diana joins Hayashi to watch a video of one of his old White Ninja martial arts flicks, he tells her that he has Paul sharpening his fighting skills at the dojo run by old friend Jon Allen; There, Paul witnesses Jon and his students use their superior techniques to dissuade some thugs from a martial arts-oriented gang, who had clearly been pressuring Jon previously; However, after most of the students have left and Jon is locking up for the night, the thugs return, with their huge, Yakuza-style boss Onaka Matahachi. He has a bazooka-like weapon fired into the dojo, gutting the place, and then beats up Jon himself for "refusing [his] most generous offer" to buy him out; Jon's injuries prove to be minimal, but Kato doesn't like this new angle to the gangs, and he and the Green Hornet go out to intervene.
