I'm beginning to think that whoever won here would benefit Baku keikaku doori style. I do wonder which side he'd prefer to win and who he planned on winning, or if due to my initial statement, he didn't care who won, so long as one side did win.
It's also impressive that he stuck a blade into a wall (of unknown material, sure), but I was thinking it must've been tough since he could put his full body weight on the handle.
