actually... technically Izuku's quirk is also a form of hardening quirk here following in the other two's steps as his quirk specializes in durability even if it does give him more strength than the other two.

Did his uncle read Demon Slayer or a sword art that looks similar to the sword technique of the same name?

I feel sorry for Mei here, and at the reader stand point, I feel that you are one of those fanfic authors who just plain hates Mineta, doesn't give him any character development (flat character) AND exaggerates his perverted side.

Additional fact about him: According to Izuku (and Kohei), Mineta is the second smartest student in 1-A, which often confuses the readers because his shtick is that he's a massive pervert, which often overshadows his intelligence.
Another fact: In some MHA fanfics Mineta is given a chance to become a better person, which often tries to eliminate his pervertedness.
There was a fanfic where 1-A got isekaid into another earth (Earth Bet) and the famous healer of that earth "disarmed" his pervertedness by spitting facts about female hygiene and diseases.

If Izuku's quirk is meant to be the same as Doomsday's adaption ability then he should be able to adapt to mental effects

Isn't he meant to adapt even in hos un-transformed state if to a lesser extent, inst that sorta the whole point. Also i would like to point out the 24 hour thing, giving exact time frame on stuff like that just doesn't really make sense yeah you can generalize it but life isn't like a video game with actual timers/cool downs etc healing like that would be continuous and depend on the severity/type of injury.

Something i've noticed and i know i'm repeating myself but why do you never mention any other type of adaptions physical or otherwise i.e strength, i don't think you've ever at one point in the story actually shown us him growing/adapting… But overall the story's looking good

Dont worry about what people say buut also dont completely ignore or take offense with it, take it with a grainbof salt as even if some ideas may go against what you want (and if they say so rudely) a lot of the time such complaints do stem from an issue in writting not nessesarily what they are complaining but sometimes in compesition or world building up to ‘that’ thing their complainjng about that rubs them the wrong way.

Now the other thing i wanted to say is dont follow the original canon plot religously, use it as a guide a reference point to help you branch off and make your own story.
By expanding upon the universe itself either by clarifing/going indepth into certain aspects or changing them allows you to branch out and create your own world. One of the issues with fanfiction writers when making a more AU universe either by deviation from a certain point or from the beginning is that they havent developed any original groundwork foundation that they can expand upon so when they leave the original work they lose direction

This isnt to be mean or demand anything buut please dont have yanagi get one for all she just isnt a good fit for it and there are obvious better options.
I and most of us i think would still prefer Deku getting one for all but i can see your justification and reasoning behind not giving it in universe wise and story wiseBut if your going to use the government as a reason you REALLY need to showcase the power of the government maybe even the royal family, maybe something similar like in ‘The Dark Below’ wherethey have selectively bread powerful quirks to create truly unstoppable forces of nature that can compare to all for one etcbut they have their own interests

So speal done but yeah thats what i would recommend if you go with using the government as a reason. Making them a truly terrifing beast with other bigger concerns than heroics.
It would also have the nice added bonus of doing some nice world building

Having him heal or say he will heal completely in 24 hours is so weird and in no way is that how it would work.
If he has a healing factor that powerful where he can regenerate limbs in 24 hours then we should see in real time any damage he suffers being healed (if slowlythe more important thing though is in how binary exact they are being on how long it takes to heal, it should vary based on the injury, his evolutionary level etc.

Now enough about that is Deku going to develop in more ways beyond a basic stronger, more durable etc like doomsday which the power is based off his body would physically change more i.e bone claws, but he would also adapt in ways like energy absorption, heat control?

Why would the commission have problems with him expelling one student and say nothing about him potentially removing 20 the year before..?

Either he has the authority to expel regardless of how fucking stupid it is or he doesn’t.

You know maybe next time finish WIP before getting yourself in a dozen of new WIPs

This chapter was a disappointment, Bakugou should have been beaten to a pulp

any chance this is somewhere innthe update cycle? i know you have alot of storys and a life but this one is fun

a suit/costume that grows and changes along his own transformations COUNTS as gear

Ik its late for the paring probably but anything but 1A or 1B girls

whats going on is this dropped hope not i love this fic
