After this recent chapter? It's very clear that Raiden is so unbelievaby ******. This dude is just dodging attacks that shouldn't be physically possible to dodge repeatedly, ascending to the sky by using particles of dust as footholds, slowing his perception to the point where everything seems stopped around him and he can't feel pain, see colors, or experience anything else that would obstruct his fighting, running simulations of years of practice in an instant to get so used to swinging a sword that he gains a huge aoe that cuts space and creates a vacuum, and so on.
And all of that is while being reduced to a kid and while not having his two swords, the weaker of which conceptually cuts the "point" or idea behind something.
