I just find it funny he is all about purity in a fight but when he finds someone physically stronger than him he betrays his supposed principles.
It's said he was left at the Baikuran temple as a child. So his parents were immigrants or is there a chinesse ethic sector that it's brown?
It always seems weird to me that Retsu would be this hypocrite and have 4000 year old of double standards.
For people who don't know him, he's Yanagi teacher. He is also an assain and a weapons expert(Not Motobe nor Yanagi level), his abilities include the void palm in hand and feet. He can also use benda and stab with his nails. Meanwhile Gouki abilities I think we are all familiar. Now for the match up. I think it is very close. Firstly because we could say Gouki has the edge, since when he was defeated by Yanagi he only lost and eye in contrast to Kunimatau who lost a whole arm. However. Gouki couldnt grapple properly Kunitmasu since he doesn't have an arm and he has to be careful to not get touched by Kunimatasu nails so he doesn't get stabbed. Even thought Gouki it's faster. I would say it's 50/50 since if either of them connects it's over for the other, since both aren't as durable.
We all know Olivia vs Sukune rematch was basically Ali Jr 2.0, same with the Baki Rematch. Sure Olivia got stronger than Sukune was missing a lot of power and injured.
Now respective to Pickle, I think Pickle would cause some problems and leave him bleeding coz of the animal aspect of him but he isn't as intelligent as Jack, so Nomi could just catch him and break his jaw.
