Now, that's a proper boss room.

Biologically speaking i guess the red lighting somehow someway makes the nervous impulse stronger so its faster?

But who cares asides nerds

I'm a nerd and I don't care. It's fantasy, not science fiction. It's a win for me if the author tries to put a bit of science in it, even if it's not entirely correct, since the "it's magic" explanation is kind of a cliche.

Okay, so contrary to popular belief, impulses on nerve cells CAN go somewhat faster than normal. But it's not by hastening the info transfer, since it's impossible to surpass lightspeed. Instead, you could just make the information go through a shorter pathway, like giving it a shortcut.

This is doable because the impulse between different parts of the body are 'policed' by a kind of nerve cell called the glial cells. When certain connections happen a lot, these connections tend to be stronger, or even sometimes redirected so they can form shorter pathways; in contrast, connections that don't get stimulated a lot get pruned. This is why we remember and forget things—some connections grow stronger or shorter, while others get pruned or become longer.

Since Tohru had to hone his battle instincts to begin with (given how he deals with basically weapons slung and mobilized with a portable railgun), he relies mostly on muscle memory, but his own combat awareness would force him to still rely on cognitive work processed by the brain. Muscle memory are just connections to movement parts that get strengthened and shortened, making them doable and repeatable even without conscious control.

I assume that his ability means he just jumped these connections to their shortest possible paths, basically using his muscle memory entirely to move. Skipping the brain also means that all his motions are reflexive and respond the fastest to stimulus. Theoretically, he could surpass human limits of processing and motion this way.

Realistically, though, the difference from that limit would be negligible for the most part, because info travels at lightspeed, and the human body is too tiny for the distance that information traverses to matter much. But it's a cool ability, so I don't care. Just very happy to see him work around his demerits to unleash his true powers!

Uh. How did using electrical spells to control his body somehow also improve the processing and reaction time of his brain? That makes absolutely no sense. He was not [described as] outsourcing the processing and casting of magic (to control the body) to some magical CPU, so the brain should still have been as slow as ever in both reacting and in casting spells.
And this is before even considering that the latency-reduction of skipping sending signals through his nervous system is only half of the signals taking its time going through it, as the signals from his senses also have to travel through it to his brain before it can even begin to process stuff.

This sounds like you are trying to imply the nervous system sends signals at light speed (or at least the neurons inside the brain)? If so, just want to mention that this is not the case. We are not made out of fiber-optics - hell, we are not even truly cybernetic machines with copper wiring. Signals in the nervous system (and brain) is more of a chemical reaction than an electrical impulse in electrically conducting wires.

And what do you mean "contrary to popular belief"? Popular belief is exactly that the signals can go faster. Because popular belief is that the human nervous system is a slow (relative to machines and computers) chemical system. It is exactly why the thing mc was doing in this chapter [bypassing the central nervous system for faster reactions], is a common trope.

Hmm, sounds indeed like you are referencing specifically the neurons/brain. So no, it is still generally considered slow, and absolutely not happening at light speed. But the rest seems entirely correct (the parts about why muscle-memory and reflexes are considered so much faster and capable than conscious movement). The issue here is that even with muscle-memory, that only works to make the movement itself faster. But does not impact the [speed of the] choice to use the movement to begin with at all.

Remember, we are all wetware. Unless you are an AGI or GAI. Or maybe a LLM or generative AI. Then odds are that you aren't wetware, and the assumption of near-lightspeed signals ends up correct.

I assume he just made the muscles contract/expand faster with electric stimulus, fast enough to completely catch up with a trained mind's quick processing ability. Like, I myself can imagine doing a flurry of attacks in a span of a second, but there's no chance in hell of actually doing them, my arms aren't fast enough.
Plus he seems to be able to control the rings as a separate entity, so he probably can latch onto them and use the pieces to rapidly change directions, ignore inertia and pull himself when even his enhanced body isn't quick enough (which is what he seemed to do to escape the trap on page 13).

This feat is achieved by sending the red lightning's impulses straight to the body, skipping the brain entirely.

I love me some fantasy settings, but this is just pure bullshit.
He still has to first think about sending those impulses and then use red lightning to send them. The brain isn't skipped at all, this fool actually just adds unnecessary steps, when he could've simply moved instantly after thinking about it.
