This imho....even when he showed his "full power" not really his full. But even then he still was just making sport of them Imo. Could have killed them all in less than 60 seconds imho. The only one I give two minutes is Ohnoki. It was like Bruce Lee Vs four 5 yr olds and one 10 imho.
would make sense if he didn't basically say he was using PS just to break their spirit and not even kill them. He could have killed them with a sword if he needed, he just wanted to see how strong they were by seeing if they could counter strong techs. Everything he did was a game and playfighting. He could have killed them with mokuton, rinnegan, EMS whenever he felt like it. It was a stomp even though they cornered him at times.
I would say low-mid diff. Not no diff though. They were good enough to repel many of his powerful attacks and it took his most powerful move, the Perfect Susano to finally put them away.
