1. Shiryu enjoys Killing Prisoners
2. Koby promised to help Perona save Moria
3. Sword Squad can't Fight Titanic Captains
4. Garp can handle Multiple Commanders
So imo, Koby & few others will go to where Moria is Imprisoned
Garp will make sure No Titanic Captain follows them, so He will fight Vasco & Wolf
And since Garp is too Powerful, Pizarro will be forced to join in & thanks to his Island DF, They can survive a Short Fight against him
However, Shiryu can go Invisible & chase Koby & Co.
Something will happen near Moria Cell which will show where this Sub-Plot is heading
This is why i doubt Shiryu is gonna fight Garp
He is also a Sword User, i doubt Oda would draw Garp punching him, so it has to be a Clash & in that case, Shiryu needs Adv. CoC to do so
I doubt He has it, but even if He does, Oda ain't gonna reveal it now
Other Three however have Punchable Face & can suffer some De-Hype
