I scrolled down the comments section to see if someone else made a joke about RAZOR LEAF being super-effective.
Someone did.
So, umm...
I guess, instead, I'm going to comment on how this is probably going to be the third Part in a row that ends in a really trippy way because Araki doesn't really get physics but wants to write about it anyway.
(In this case, he's latched onto the "one-dimensional objects don't exist" concept, and run with it)
(Ignoring completely that if the spinning one-dimensional object can be seen despite not having thickness, it must spin faster than light, in order to act as a solid and deflect photons)
((but, I mean, that's not actually the problem. This is JoJo we're talking about))
(The problem is that, despite spinning so rapidly, it was somehow still recognized by Mamezuku as a spinning one-dimensional object.)
(As established, this cannot have occurred while the line is in sphere form, because no human eye can track that motion.)
(This means he can see the line when it stops moving. Which means the line has thickness.)
(Which means the line exists. Inherent contradiction.)
But whatever. Let's turn the president into a slinky.
