Iron Fist

The style used by Kamogawa when he fought Anderson (Hajime no Ippo) causing your fists to become like iron and leave an imprint on your opponents body when hitting them

Kamogawa: "ATTACK!!!"
Kamogawa: *nails andersons liver with a left bodyblow leaving an imprint*
Audience: "THATS THE IRON FIST STYLE!!!!!!!"

I'm you.

This is a phrase Yuji Itadori from Jujutsu Kaisen said after beating Mahito in battle. The Phylosophical meaning behind this is as follows: Killing humans is as natural to Mahito as killing Curses is to Yuji. Basically that Yuji shouldn't assume he's "better" than Mahito since he's just as focused on killing. It's also dependent that Mahito said Yuji is him, because of the previously mentioned nature of killing. As Yuji said this sentence, he accepted the fact that he is no better then mahito, and simply, like him.

Yuji: "You're right Mahito, I'm you. I wanted to reject you. Convince myself that you were wrong. But that doesn't matter now. I'm gonna kill you. Even if you come back as another cuse... I'll kill you. Change your name. Change your form. I'll kill you again."

Mahito: *pissing his pants*
