If Boa is DD level,that is more than enough for Koby.I don't think Koby is THAT strong yet.I place him into veteran level at best,but you know Oda said he learns faster than Luffy.Maybe he awakened advanced haki fighting Boa.
Yea those are some dogshit scans
Random glowing shit
And some kind of filter that makes it look like kid drawings
Makes me appreciate TCB all the more tbh, they do a really good job
Robin got that huge ass bounty because the WG wants to see her dead.That is it.She is the key to the one piece.WG doesn't know about pudding,Tengu dude and the man marked by the flames.Former Roger pirates would rather die than spill the beans.
