You can't explain how 108 pound canon was stronger than an original 108 pound canon without admitting that Shusui at least 2x enhanced it..
You kind of dig your own grave there..
'' My Blade '' burns those '' It '' cuts..
And it doesn't mean because Kinemon's Blade allow him to cut fire effortlessly that you can't learn it..
Just like some blades like Shusui allow to coat CoA to air slashes effortlessly, doesn't mean you can't learn to coat CoA on your Air slashes, but it requires a higher Haki degree of mastery that was not explained yet with CoC..
How do explain that Hancock was able to Damage Luffy with her fruit when it has no effect in the first place on him..
It enhanced the effect, it did more than what Zoro wanted, Zoro comments that it is heavier and then uses the weight and power to deflect Oars attack, then launches the 108 pound canon. Then comments that there is too much pointless destruction around the cut. The attack power is higher but the blade is ill mannered and Zoro will have to learn to wield it, Zoro is not used to it.
Nobody is saying that swords dont have different grades, different properties. The problem is you implying that a sword gives random powerups that are not earned. You give Shusui to Brook and he wont be able to use it like Zoro.
The panel I posted literally says that Kinemons Foxfire style lets him cut with flames and also cut flames. Re-read, Kinemons Foxfire style. If it was dependent on Kinemons swords then Zoro should never be able to copy it. Zoro also already showed flame attacks by setting Ryuma on fire with Hiryu Kaen.
Where do you bring all the headcanon from that Shusui adds CoA to air slashes?
What higher haki degree, stop pulling things out of your ass.
Hancock DF and the conversation we are having are two very different things
Then, it's Wado's power, purification or something..
Headcanon
