I hope so. Or else it makes Brooke look kind of lame.
"Woah! That's my attack, except much stronger!"
"Amazing! I could never perfect that attack but he did!"
"I can't believe how much stronger his techniques are!"We'd end up seeing most of Brooke's moves and then there'd be nothing left besides his own weaker version of the attacks.
Well, I think Brooke told Ryuuma in an earlier chapter that when he does the Arrow Notch Strike, he doesn't do it correctly. So that would essentially be Brooke's trump card.
