Ryofui made his King, Ei Sei pissed his pants during his first debut.
That's like the equivalent of Blackbeard making his captain, Whitebeard and Whitebeard's whole followers shitting their pants just by flexing and saying little words. Except that's never happened
P.s.
Blackbeard will get his ass kicked by Luffy. While Ryofui only fell thanks to Shoheikun's betrayal.
That's like Blackbeard would about to win if not thanks to Burgess' betrayal, except again we know it ain't happening
