So in this world nails are treated like trash well not really like trash but they're treated less than females males are always treated like second class

So our main character had two sisters they were a little bit older than him also females are like taller than the males so pretty much they were treated terribly

In this universe the normal height of a female is well whenever they're fully an adult maybe 8 feet or a little bit more I know that sounds tall but my choice and usually the height of a male is like half of 8 feet which is like four and males are treated as breeding horses

So he was treated completely fine and well his sisters like grew up and looked way older than him because they grew taller faster than their brother because he's male obviously

And while they had a brother complex and they loved on how small and adorable he was so pretty much they sort of shared their brother what I mean by that is that well because of how small he is he can sort of fit underneath their clothing pretty much

Which for some reason it just helps them sleep better when he is next to one of them they switch off every other day

Then they went to check their quirks and Deku stayed home watching TV with a smile on his face also his foot he's friends with class 1a all of them and they do protect him from bullies

And his sisters quirk was this
Izumi: quirk enhanced telekinesis
Izuma: strength enhancement

So anyways so once his sisters and Mom Scott Home well they slowly started to ignore our main character they were like doing something or had something planned something

So our main character sort of fell asleep in his sister izumi shirt pretty much since like I said before he fits perfectly and they were watching TV and he was using his sisters chest as a pillow

So they sort of turned on TV and saw like how a Heroine was killed they looked at their adorable brother with concern and they know he wants to be a hero but is afraid of losing him so they talk to their friends about it and katsumi came up with the stupid idea of bullying him until he gave up

Which they were like saying I don't know if that's a good idea because he's going to get bullied enough as a male at school as it is then she said do you want him to die or not

His sister said no which and then she said that this is the only way which is totally wrong so they go to our main character and ask if he wants to be a hero still which he replied yes and then he was hit with a punch from one his sister switch it didn't really hurt for some reason little does he know that his body is different from others so after that he was just left there beaten up and he's smarter than anyone in his school he always has been and shows it but the teacher didn't like that so they just try and fail him or to the least of his class anyways

So after like two years of abuse he learned something special of him self so he was on his Waze somewhere because he had to do jobs of his self because he needs money and Well the hero tried to force her self on him much this was at night and she stabbed him in the eye with like a scalpel or something to try and knock him out or that there was actually make him angry so he pulled it out and stabbed her in the throat and while she was choking on her blood he pulled out the weapon and started to repeatedly doing it giggling and laughing because he enjoyed the suffering of others it took him two years to figure out he enjoys the suffering of others and he was six at the time he was still like probably 3 feet tall possibly sans The skeleton level height

Also he wasn't done after that happened he started to mutilate her body by like chopping chopping her head off for cutting it with just the scalp all alone which is very hard to do but he was able to do in less than a minute I just proved that he was made for this type of thing

But that's not work is even worse he took the hair home later that's what he's planning on doing but after that let's just say he also did awesome like surgery on her and started to open up her chest area and took her heart and started eating it because well his parents don't feed him at all so he needs to get food himself even if that resource to cannibalism

Not only that but he placed the head on something for anyone who walks by to see it
And he was starting to like devour parts of her as well because he was still hungry and his face was sort of covered in blood then he got up and started walking home after wiping off all the blood and that

And he came home with an evil grin although no one even paid attention to him but she was used to that and the day that that happened was Friday so whenever he woke up he heard the news and downstairs he started hearing on how his sisters said who would do this type of thing what monster would mutilate her and take her hair

Although he did also take her eye to replace the one he lost which for some reason it actually started to replace his I actually didn't do that that's when are you did realize he's a Being from just something else he's an entity and not a good one well he's good at what he does in his own way

So anyways after he heard that he smiled more but he obviously escaped because no one would think a male who is like 3 feet tall right now who would be able to do something like that

So anyways he got back home and saw his first kill and he smiled putting it somewhere and he kept something as a reminder of why he does it although his first skill was easy without any guilt because he's evil and yeah

So after a few days of this happening everyone is have been just trying to find out who she is nothing came to mind and let's just say the tormentors came up with a brilliant idea to try and capture him for fame and deku love/lust which Deku really don't like that even though you can easily kill them even if they were going to fight him because like he is physically stronger than anyone in his school even with his sisters strength quirk he has superhuman strength

Also apparently this is actually a Canon thing just so you know apparently he can warp reality and he can he has dimensional travel which would explain how he gets to places very quickly especially with his healing factor which is probably it's not that strong because it's like it took them a year to like regenerate and yeah but I don't know if that's because he was decapitated or what because he was definitely decapitated in the second movie but he still alive
