How Is This The Best Explanation I've Seen Of Hagakure's Quirk, Like Genuinely.

How is this the best explanation I've seen of Hagakure's quirk, like genuinely.

And it's for a rewrite, like no that is just how I'm going want her quirk to work now, it makes so much sense.

Quirk Analysis #1

As promised, this post is for the quirk analysis of the following three students!

Kirishima Eijirou, Ashido Mina, Hagakure Tooru will be discussed in this post and in that order.

Kirishima Eijirou:

Fatty and oily foods make Eijirou's skin harder, and Izuku hypothesises that it's due to the carbon content. While carbon is often associated with gases or coal, it's in food too, with the content being higher in oily or fatty foods. Eijirou manipulates the carbon in his skin by rearranging the carbon molecules to make it denser, to the point that his mohs level of hardness is equivalent to corrundum (level 9, one level below diamond).

Because of this, eating food containing high levels of carbon makes it so that there's more carbon to push between his skin cells.

While ordinary humans cannot properly digest high levels of carbon, Eijirou's body is able to, not just handle it, but properly digest it. As such, he starts eating activated charcoal, (which is safe to eat in small dosages, though Eijirou can have more), which increases his time limit, and can help him harden his entire body for longer periods of time.

It's also theorised that his teeth are sharp so that he can bite into coal.

Ashido Mina:

The most obvious contender for what her acid is made of is stomach acid, however, if she transported her stomach acid to her skin, it would make her either incredibly ill or she wouldn't be able to digest things, as she subconciously produces acid.

As such, it's much more likely that she's using carbon dioxide. It's usually pointed out as a gas, but it can exist in a liquid form. Carbon dioxide naturally exists in all humans, though typically as a gas that our body filters out through breathing. Mina is absorbing carbon dioxide as opposed to breathing it out and changing it to a liquid form.

She can alter the pH levels, though it's naturally low, around pH level 3, which leads to accidentally dissolving her bed and floor and waking up in the flat/apartment below. Don't ask. She can make the pH levels go up to about 7, which is safe to drink, though it's not recommended, and this allows her to use her acid to slip around the ground.

While she could theoretically try breathing less to increase carbon dioxide intake, but that's very dangerous without proper training. Instead, she takes sodium bicarbonate or sodium citrate pills, which increase the level of carbon dioxide in the body.

Her appearance is not connected to her quirk.

Hagakure Tooru:

Now, if Tooru were truly invisible, she would not be able to see, as the way we see is by light hitting our retinas, which bounces the light to the photoreceptors behind them which send the electrical signal to our brains. If the light passes through you, the light can't hit the retinas, meaning that no information would be sent to your brain, leaving you blind.

As such, reflecting light also cannot be her quirk, as this would lead to the same results, and would make her continuously shine.

Her quirk is actually absorbing and manipulating radiation across her skin. She doesn't feel hot or cold, as seen by her steaming lunch and how she can run around naked without a single shiver, and this is due to manipulating the thermal energy, which is a form of radiation.

Light is also a form of radiation, which is why she can produce flashes from her skin.

This could also mean that she cannot become irradiated by things such as chemical energy, though it's far too dangerous to test out.

Additionally, because of this, it's possible that she can manipulated energy across things made of her DNA, which is proven true when she gets her costume and appear invisible after she wears it.

...

So that's Izuku's analysis of Eijirou, Mina, and Tooru's quirks!

I'm not a master of science, so if there's something that doesn't seem quite right, chalk it up to psuedo-science, please. I did not take A-Levels for science. My knowledge comes from my own research, mainly due to Momo's quirk.

Thanks for tuning in!
