Introduction 

Midoriya Kou is main character of my Boku no Hero Academia fanfiction named Abyss. From the name most can already guess that she is relative of protagonist from BnHA - more precisely she is his twin sister. As such they are the same age and until the end of Primary school they were always together. Before starting Junior High she moved away to their grandparent’s house and started to attend different school than her twin. However, she came back to live with her mother and twin once she finished her Junior High school.

The meaning of the name Kou I use in this fanfiction is ‘light’ and I actually do have a reason why I used this meaning (I actually have more than one, but that would spoil more than I am okay with). It is supposed to represent that in her second life she was given chance to live in ‘light’ while most of her past life was spent in ‘dark'. If she actually takes this chance fully and stays in light or if she gazed into abyss for too long to be able to stay, remains a mystery for now~.

Past life

Kou is reincarnated OC and remembers most of her past life, but as she never saw anime or read manga, she doesn’t know that she was reincarnated into anime world. 

There is not much to say about her past family as she was unplanned/unwanted child and her parents didn’t really like her, but they at least took care of her basic necessities. Though they, along with other people she sometimes interacted with, cut all ties with her after she ended up in prison.

When she was 10 years old, she met Theo. Who, after short while, became her best friend and at the same time the most important person to her. She spent her next eight years pulling him out of troubles that he got himself into because of his kind and virtuous personality. However, few weeks after she turned eighteen, Theo died in her arms. Losing all her reason, she tried to kill the one responsible, only to end in jail. 

Once she got out, she firstly gathered money, experience and information, moving around in darker side of the world. Once she was sure she was prepared enough, she successfully killed the person responsible for Theo’s death and then... well she just did whatever. Not really happy about living, but not wanting to die either. She worked as courier, transporting various things that are best not to be specified.

Then, she died when she was thirty after making a novice mistake and ended up being reborn. Her second chance as Midoriya Kou started!

Appearance

Because she is twin of Izuku, she is very similar to him in appearance. However, there are several differences between this pair of twins.

The first being their hair. While Kou’s hair is very curled, it isn’t to the point where it can’t be tamed. She usually makes one or two braids out of it, because she doesn’t have patience with long hair (she only let her hair grow because her mother liked it that way), but when she does let it free, it is just ‘curly’ and it doesn’t stand into all directions like her brother’s tends to. However when she combs it... she ends up resembling a poodle (she is still unaware that all she has to do, to not resemble this dog, is not comb her hair, thus she stays with braiding). Anyway, her hair is lighter than her brother’s but not by much. I’d say the color would be something like this. That’s probably all for hair. (If you can’t visualize how she looks with braids, this is pretty close to my image).

The next is that while Izuku has few freckles under his eyes, Kou’s cheeks and nose are completely sprayed with them. Her mother thinks it look cute and Kou is like ‘Meh’. 

She is taller than Izuku by quite a lot in their early teen years, but by the time of High school the difference evens up a little, because of his growth spurt, however she is still taller than him by few inches. 

Their face shapes and eyes are similar, though Kou looks more ‘harsh’, probably because of her ever present scowl and glare. 

Personality

Calling Kou antisocial would be an understatement of a millennium. She doesn’t do ‘friendly’ stuff and for most cases she doesn’t even do ‘civil’ stuff. But to not be so harsh on her, if she is in a good mood and if the person in question didn’t offend her in any way, she can be fairly mild towards them.

However, mostly, she is just rude person who glares at everyone that aren’t part of her ‘okay group’ - into which is nearly impossible to get as that person either had to be very persistent or they have to strike her weak points (one of them being sweets).

Thus she is considered unapproachable and ‘run on sight’ person. The rumors that circulate around, labeling her as delinquent certainly don’t help with this image. She does nothing about them as; 1) she doesn’t care and 2) they are kind of true... She can’t help that she likes to fight, okay??

Her bad points don’t end here, too. She can be easily angered and is very hot-tempered when It comes to her brother. Her morals are also a little screwed because of her past life. And she sometimes seems to think very lowly of herself even if she denies such a fact. 

But, in the core, she isn’t a bad person. If she sees someone in need and it won’t bring her much trouble, she is willing to help them. She would never kill a person without reason. And when she considers somebody family or friend, if someone hurts him/her, they’ll have her hot on their heels, roaring and fuming for revenge. 

She can also be quite reasonable and is able to think things through if situation calls for it (and if the situation in question doesn’t involve her brother). Her realist part sometimes brings her more trouble than anything as she is easily confused when someone behaves in a way she wasn’t expecting and can even freak out if the situation suddenly goes beyond her understanding and control.

She has soft spots for animals and sometimes for kids, if they aren’t annoying brats and can do killing puppy-dog eyes.

Kou can also be pretty stubborn when she sets her mind onto something - it can be viewed as good trait in some cases.

Relationships

Family Her family consists of her, her twin brother and mother. Father isn’t around for most of time because of ‘mysterious reasons’. After twins reached one year this little family was extended after their grandparents were introduced. Her mother is supposed to have an older sister, but her aunty still didn’t make an appearance. 

Midoriya Izuku (Kou either calls him Izuku or otouto) She has best relationship with her brother as she decided early on that he will be her most important person in this new life. However, still remembering what happened to Theo (and seeing so much of him in Izuku), she ended up doting on her brother and being very protective of him. To the point where it was unbearable for him and he ended up ‘blowing up’ after bottling everything for some time. Even if she decided to move away for Junior High, their relationship didn’t worsen and she is still in ‘doting’ mode whenever they call/text each other. She tries to restrain herself a bit, however. 

Midoriya Inko (called mom) Her relationship with her mom is very easy-going and pleasant. She loves her mother very much, but while she does see Inko as her mother, she can’t bring herself to depend on her the way child should, because she is mentally older than her. Inko is aware that the older of twins is different in many ways, but is very understanding and doesn’t force her to behave like normal kid, instead she accepts that her daughter is just special. She is sometimes sad that she isn’t depended on more, but all the more she treasures those rare times she can help her with something (for example how to use quirk).

Midoriya Aihi (called granny) Their start was pretty rocky as granny was mean to Inko and that wasn’t something Kou could stand. In the end, it turns out that Aihi is even more socially inept than Kou (and that’s quite a feat). Their relationship now is quite good as they share their love for drawing and as fellow unsociable individual, Aihi could be quite understanding at times. However Kou’s grandma is also very traditional woman and is easily displeased when Kou behaves ’unlady-like’. She started to teach proper manners to Kou from very young age to nurture a proper lady out of her, but as of now she gave up. Instead she changed her lessons as is now trying to make a good housewife out of Kou.

Midoriya Manabu (called grandpa) Not much I can really say about their relationship as he spends most of time with Izuku (he always wanted a son). He is kind to her and doesn’t ignore her and when they talk with each other it’s enjoyable for both, but they don’t have any need to seek each other all the time when they are in the same house. 

Midoriya Hisashi (called father) He dosn’t spent a lot of time with his family as his work is pretty time consuming and also if his relation to them were to be known, they could be put into danger. Kou has neutral feelings towards him (though she is pretty peeved that he left his wife like that) as she can’t really guess his reason for not being with his family (and still sending money). She always have near her bed the cat keychain he gave her (Izuku got one, too), though. 

Friends As I said before, Kou isn’t very friendly individual. One can even wonder why would someone want to be her friend, but surprisingly she has quite a lot of friends??? As of now, her friends include: Akaguro Chizome, Bakugo Katsuki, Ashido Mina, Shiozaki Ibara. And next chapter one other person will appear...

Akaguro Chizome (usually rudely called ‘Chizome’) More known to readers as ‘Stain’. Yes, I did this. Anyway what I want people to know first, is the fact that they met each other when Chizome was still very young and ‘unstained’ (heh... unstained... stain... get it?) by killing. In canon he would have already started to train his body few months before his parents died and their deaths would only cement the idea of killing (at least I am going with this reasoning, his past is very vague). But, he is different in this FF. He met Kou and while some may see what she did for him as ‘small things’, even those small things could make big differences. Anyway, so, he sees her like weird little girl that he can’t help but to be fond of and I suppose he sees her sorta like his little sister. And Kou? Well she is just like ‘Meh, I suppose now it’s too late to erase him completely from my life. He is here to stay I guess.’ But secretly she totally likes him (not in romantic way, mind you).

Bakugo Katsuki (nicknamed ‘shorty’ by Kou, sometimes called Katsuki) Hah. I personally very enjoy their relationship. They started as enemies/rivals/nemesis whatever you want to call them. They fought each other every time they met and Izuku was just standing there, in the middle (as Katsuki’s best friend and Kou’s twin), slowly developing a ‘totally done with your sh*t’ attitude. As time went, they somehow became friends and the number of fights lessened (mainly because Katsuki interacted with too much damn brats in kindergarten and she would never go near those kinds of crowds. Never again). As Kou took it upon her to reduce Katsuki’s ego every time she met him, he grew up to be different from canon. He is more closer to Izuku than he was in anime/manga and he is also a lot calmer (though with Kou being away from three years, he will probably become a little wild). He is more like the Katsuki in later chapters of manga. More serious, mature and well... certainly not a bully. Doesn’t mean he isn’t loud, arrogant, swearing brat, though - I don’t want to take this from him, he is very interesting character in canon, if he just wasn’t such a bully... Well anyway. Some people (read most) think that just because Kou won’t be here for a while, he will start to bully Izuku and be overall shit he was in canon. Nope. Not happening. I love Katsuki I made in my fanfiction, thank you very much. He will become even more violent and loud, though... 

Ashido Mina (called Mina) The newest addition into a gang and simultaneously the strangest one. She abruptly appeared, confused the hell out of our poor Kou, somehow managed to push her into socializing and then squeezed out a promise of meeting everyday during lunch break out of Kou. All of this in only few minutes. Scary girl. Even I, as an author, was surprised by her sudden appearance. She just pushed herself into my fanfiction. Very scary girl indeed. Ah well, anyway, her actions remains a mystery to all residents of Earth. She is future BFF of Kou.

Shiozaki Ibara (called Ibara) I needed someone to pair up with Kou for school things in Primary school and also for Kou to not look so unsociable... heh. And well, Ibara just happened to be that person. I don’t have their relationship fleshed enough as I came over the primary days pretty fast. I can only say that while they are sort of friends, they aren’t close... The both have more important friends.

Kirishima Eijiro (called Eijiro) Their relationship is difficult to explain as she doesn’t want to do anything with him as she thinks of him as ‘weird’ and all he wants is to be friends with this ‘girl with manly heart’. Also he kind of has a small crush on her which creeps Kou out even more and makes Mina laugh her ass off. 

Love interests  Ah well, this is added because I know some will want to know this in the future (or already want). So just saying this now: This fanfiction will probably be without any romance. I can make small ‘teases’ or crack pairings and probably some fluff, but there will be no actual romance. The thing is, I see Kou as aromantic person as while she can have platonic feelings. she can’t be romantically interested in anyone. There is also this thing that she is mostly 30+ years older than her peers (or at least her mind is) and is very much aware of it. So yeah, probably no romance.

Special traits 

Quirk Kou inherited her mom’s quirk - attraction. However while Inko can only attract smaller, lighter object, Kou is capable to attract heavier objects. As long as they are lighter than her she is able to attract them towards her (though heavier object are harder to attract). Also, when the object is heavier than her, she is instead the one pulled towards it, though the landing is very uncomfortable and she has problems landing on her legs. Kou likes to experiment with her quirk, so she is capable to do a lot of things with it now - she can attract things to her so fast untrained eye can’t catch it or on the other side she can make it go to her so slowly that it nearly looks like it isn’t moving. She can also pull people towards her, but only if they are lighter than her (it’s the reason why she makes sure to weight more than Izuku - she wants to always have the possibility of having him near her). She never tried to attract towards heavier people - the collision would surely be painful. She also likes to attract pointy things to her randomly - certainly doesn’t help her image, as anyone can guess.

Fighting style In her past life Kou used to fight a lot and she still retails memories of her fighting style, though she had to alter it a little because her current body doesn’t have and probably would never have, as much strength as her past had. She usually hits the most vulnerable and painful areas to quickly immobilize the person she fights, using her smaller and usually more flexible body to attack from directions other party isn’t expecting. This style requires her to know human body quite well - she doesn’t regret all those long weeks spent on remembering each part of a body, it was quite satisfying to know more about one subject than most people. She is currently trying to incorporate her quirk into her style, too, and it is going quite well - others don’t expect things to fly at them from different directions when they fight someone. She also doesn’t mind playing dirty - spitting, biting, targeting crotch isn’t above her. Both Katsuki and Chizome were unfortunate enough to learn this first hand. While she was quite skilled in using knifes in past - she didn’t really had any chance to use knife in her new life as for her, using knife means she wants to kill the other person. She, however, always has pocket knife on her. Just in case.

Likes & Dislikes & Hobbies

Likes She likes to eat sweet things. A lot. It’s practically the only thing she spends her pocket money on. Strawberry flavored ones are best, but others are cool, too. She likes every person in her ‘okay group’, her family and her cat named ‘Miss Cat’ (Did I already mentioned that she has the worst naming sense? No? Well then, I am saying it now). Her new homeroom teacher is okay. Every type of vehicle is cool to her, but cars and motorcycles the most. She enjoys driving, but altering them and rummaging through them is fun too. Her favorite subjects in school are English, Physical Education, Art and Physic. She surprisingly finds Math okay in this life, maybe because she never paid proper attention to it in past life. She likes to wear comfortable clothes, that don't restrict her movements.

Dislikes She dislikes vegetables, but she eats them without protesting. Though she very much refuses to even touch broccoli. She doesn’t like practically everyone that aren’t in her ‘okay group’. But there are some specific groups of people she very much dislike with all her being. Those being bullies, people who annoy her deliberately, people who make fun of her brother and... her Primary homeroom teacher - she deserves her own group. Her most hated school subjects are Japanese language, Biology (only because of her Primary homeroom teacher), History and Geography. And school in general is a pain in the ass for her.  She refuses to wear frilly clothes and hates school uniforms with passion.   Her biggest fears are angering granny and bugs.  Also she isn’t a biggest fan of Grandma’s lessons.
