I was wondering what Hikari's parents are like, since we don't know much about either of them. What I'm mainly interested in is what their personalities are like, and what are some of their notable traits. I'm asking since I want to do some more writing, but I'm also really curious about them.
formally introducing hikari's parents and a little more insight on why she's so well-known!
if any of the text above is hard to read, i put that plus some more extra info under the cut :^)
Hisako is the illegitimate child of retired pro hero Amaterasu, and super villain Necromancer. Her family, especially her mother and herself, was under fire for the shocking scandal between hero and villain. Although her younger half-sister Hikari had no blood relation to the villain, she ended up going to UA to protect their mother and Hisako. She met Hiroyuki through Hikari's internship, where they eventually fell in love. Because of her hardy and confident nature, Hisako often taunted and challenged those who wanted to try hurting her family, unafraid of death. She was involved in a bigger incident because of her blood relations, unfortunately getting others involved and others killed. The scandals surrounding their family have toned down in the recent years, especially after both Hikari and Hiroyuki aided in arresting Necromancer.
QUIRK: RESPAWN
Hisako’s quirk allows her to come back from the dead, waking up from the place she last died without any injuries or complications. She inherited one drawback from her father, though. The more often she respawns, the more her body will rot away. Because of several incidents in the past, her left arm and lefthand torso have been reduced to a skeleton’s. Doctors say that she isn’t immortal, and that she’ll just die a normal death at old age.
HIROYUKI KAMINO
Hiroyuki was born in Cairo to an Egyptian mother and a Japanese father, and they were immediately blessed upon his birth. Born with a quirk that framed him with the spitting image of the ancient sun god Ra, it was not hard for him to gain power and popularity with dreams to be Egypt’s number one hero. Both parents realized being in favor of the people might blind him, so they brought him to UA as a transfer student to humble him. This toned him down, but it didn’t change his boldness and self-assurance after graduating from Japan’s top hero school. He continued his dream and eventually became the rising hero ablaze, Ra. Years later, he took an intern from UA named Hikari and was infatuated by her older sister, Hisako. While courting her, he had to face her demons alongside their family and swore to help them regain their honor. Getting involved earned him a spot in the scandal, but he and his intern were able to capture Necromancer in exchange for losing his upper beak.
QUIRK: SUNFLAME
Hiroyuki’s quirk is manifested through the orbs of fire he can create, resembling a small sun with rays. Unlike fire, which is a type of hot gas, his suns are made up of a blazing combination of gases in the form of plasma. The plasma is a state of matter similar to gas, but with most of the particles ionized, and he can make these suns as small as a pinball or as big as a person. He’s only ever made one as big as a building once, but it takes a huge toll on him. Because of his quirk, he also has a complete and total resistance to fire and heat.
ive only realized now that I didnt exactly answer u correctly @skiduffle so let me just.....casually do bullet points HAHSGHJAHJS
hisako is very VERY strong personality-wise
she's very confident in herself to the point that she challenges people who are stronger than her or better than her
very cocky when it comes to those things, and is barely affected by anything bad against her 0% damage, she's used to it
would probably give the BEST GODDAMN PEP TALK TO ANYONE WHO IS A VICTIM OF BULLYING (watch the victim sock their bully in the face the next day after talking to her)
was the one who protected hikari the most, not wanting her to go through what she did
extremely honest and has unwavering optimism to the point that it's a bit scary how easily she can brush anything off
hiroyuki is also confident in himself and his abilities, but he's a much more toned down version of his vain self as a teenager
no one can stop him if he wants to do something or get something! he pursued hisako even if she kept ignoring him at first
definitely the one who spoiled hikari the most as a child, especially since he came from an upper class upbringing
total dad who thinks hes super cool no matter what he does, likes looking cool and hip while his wife looks formal
both of them still act like they're still high schoolers dating so its a bit embarrassing to watch them flirt
"you had a crush on me..? thats embarrassing...." "I know, im so embarrassed I think of kissing you everyday...." [literally married]
I would say theyre girlboss and malewife personality-wise, but hisako is actually a housewife and hiroyuki does the hero work
if you didnt know who they were (esp hiroyuki being a hero) one could easily assume hisako was the breadwinner
hiroyuki doesnt mind! he's absolutely in love with his wife and he loves having her in the spotlight and bringing his wife to formal events to absolutely wow everyone with how charismatic she is
hisako on the other hand was never the type to want any protection, so at first she always rejected hiroyuki's pursuits but eventually her husband is the only person she lets her guard down with
some context for each image and oc credits under read more:
These explanations won't be super in depth but I do think a bit of context is needed.
Image One:
Boni Mizumi (@flowersinorbs)
Tano Hoshizawa (@zedthebuggy)
The idea behind this one is Tano is one of the tallest students in 1-Y and the only one I can see accidently hitting the top of the door frame, with Boni being the shortest student in class 1-Y for comparison.
Image Two:
Yori Hayashi (@beetroot-bot)
Yori's quirk relies on her getting injured, so whenever she gets out of the nurse's office she is ready to sustain more injuries, saying the funny office quote (even though the context is COMPLETELY different to my knowledge)
Image Three:
Tokiya Iori (@skiduffle)
Tokiya's quirk actually requires a lot of math since he needs to keep track of all of the different variables that the stacking side effect of his quirk relies on. Because of this, Tokiya helps out some of his classmates with their math work as a bit of a tutor.

Kurumi Yamashita (@nightseeye)
Doku Kisa (@dokukisa)
This one was very much "who would do this?" and "who would enable this?" even though I'm not super sure how in character that is for some of the characters. I also tried to keep it even between the two classes as well.
(if you're cool with answering) how do i look in your minds eye?
one of the most guys ever. in this art style specifically is how I imagine you. you might have a mullet??? either that or your hair is a bit grown out. you're listening to some cursed music. you have a very comfy hoodie on. faint omori vibes. There is an absolutely batshit thought under that neutral face.
Alright so I got very bored so I am attempting to create another writing tool for anyone hoping to write for the bnha oc comeback.
This will go into detail explaining each of the students, and teachers' quirk types, and how each characters' physical form is effected by it.
If any of the original creator's of the characters find any details that need to be corrected please let me know.
Now without further adieu, the writings will be under the read more:
Quirk Types
There are three types of Quirks according to the My Hero Academia wiki, along with one known sub-type. I will be paraphrasing the explanations from the wiki, so if you are interested the full descriptions can be found here.
First there is the Emitter type. The Emitter type allows the user to control "emissions". These emissions are basically external elements that the quirk user can control, whether these elements are external or are created by the quirk user. Where the emissions come from is different depending on the quirk.
Second there is the Transformation type. The Transformation type is a type of quirk can alter the quirk users different features, sometimes enhancing features, sometimes removing or adding features. Transformation type quirks require a lot of concentration to stay active. It is also important to note that transformation types can only effect the user, and no external forces.
Third there is the Mutant type. The Mutant type is one of the few types that could have been awakened since the birth of the quirk user. How Mutant types work is that they give the user a more complex abilities. It is also the most common quirk type to be passed down due to it being caused by a change in genetics. The best example that I can use here is how Tokoyami has a bird like head, but it does not inherently effect how his quirk, Dark Shadow, works. Mutant types also can not be "turned off" or stopped in any way, being forced to always be active.
Then lastly, there is the only known sub-type as of writing this, the Accumulation type. I'm going to use the wiki definition for this type because it is short and simple, so I thought it fit well. "Accumulation-type Quirks are powers that, in order to function properly, require the user accumulate something ahead of time, such as power, energy, mass, or a particular resource. Some such Quirks are One For All, Stress, Rewind, Fa Jin, and Fat Absorption." Nobody in either class seems to have this quirk type, but it is important to bring up since it is one of the more impactful types in the show, since One for All falls into this category.
I will be using colored text to help show what each student and teacher's quirk type, but I will not be coloring the text for quirk types that do not corelate with the characters.
Class 1-X
Osamu Sato (@dantelionwishes)
First off we have Osamu Sato, Class 1-X's homeroom teacher. Sato has an Emitter type, because he is able to create the emission out of his own saliva that can work as a stimulant. But because of issues from Sato's past, he chooses to act as if he is quirkless.
Moa Fuwa (@you-may-call-me-meme)
Moa Fuwa has two quirks, one being her main quirk Pressure Control. According to Moa's bio, Pressure Control, which she inherited from her father, which allows her to move objects over a certain distance , solidify objects, and even strengthen an object's gravitational pull. This quirk can be classified as an Emitter since it does not rely on the user needing to be transformed or on any physical mutations. Next is the quirk that she inherited from her mother, giving her traits that would resemble a sheep. This quirk would be classified as a Mutant due to it inherently being a part of her physical appearance.
Hibiki Manami (@3080-manami-hibiki)
Hibiki's quirk is quite clearly a Mutant type due to it appearing to never be able to turn off, and significantly changing her physical appearance.
Burai Banzai (@buraibanzai)
Burai is actually almost threw me off, so I'm glad I've been reading over the character bios, but Burai actually has a Transformation type quirk. This is because Burai's quirk allows him to transfrom some of his cells into electricity, making it a Transformation type.
Amorette Calhoun (@napstennoji)
Amorette is another tough case, but I think she would be an Emitter type. This is because she is able to control an outside force, being able to increase her opponents dopamine or norepinephrine.
Akihiko Arakan (@captainbaeremy)
Okay, so it is common knowledge that Akihiko does not have a quirk, but I did want to point out that he is still very competent, being able to make it into the Hero Course and passing the practical exam, which for those unfamiliar consists of the possible hero course students of having to beat robots and gain points for the different robots they destroy. So even though Akihiko is quirkless, I would argue he is probably one of the strongest students between classes 1-X and 1-Y combined.
Michiko Watanabe (@residentquirksupport)
Michiko's quirk is an Emitter type, because it is an emission that boosts the quirks of others. Michiko also has a small Mutant being the suits under her eye that would change under her eye depending on how she is feeling.
Makoto Shiba (@dantelionwishes)
Makoto is a bit hard to place because of how it inherently works. I think it is safe to assume that it is not an Emitter type. It is hard to tell if Makoto is primarily a Transformation type or a Mutant type. Makoto is most certainly at least a Mutant type due to her... virtual appearance? I would also argue that their quirk can work as a Transformation type because she is able to transform to get into whatever piece of electronics she would need to get into.
Jiro Yukimura (@zer0-10)
Jiro is very simple to identify, being an Emitter type, due to being able to make the emissions of his slime from his mouth.
Taishiro Watanabe (@angrymemesandicecreams)
Taishiro is also pretty easy to identify, with him being primarily an Emitter type, due to his control over the way time effects someone. Taishiro also has a small Mutant type quirk, being his eyes. I'm not gonna count the black gradient on Taishiro's arms and legs as a part of the mutation, since it seems that it is more connected to the Emitter part of his quirk.
Jetsam Kisa (@jetsam-kisa)
Jetsam is an Emitter type, with the emission being the pollutants from his mouth. Jetsam also has a small Mutant type quirk being the purple pigment to his skin, but I am not 100% sure if this is a side effect from the Emitter part of his quirk or not.
Edit: Thanks to jetsam-kisa for telling me some of the details about Jetsam's Mutant type quirk. How it works is that Jetsam's eyes are able to see shapes in the fog, helping him get through it. Jetsam's mutation is also visually noticeable through the eyes, with Jetsam having a black sclera and an off-white iris and pupil.
Tsutsumi Natsumi (@glitchviper)
Tsutsumi is probably one of the most clear-cut answers. Tsutsumi is a Transformation type, having the whole concept be that she transforms to a form where she is a lot faster and stronger.
Edit: Thanks to glitchviper for pointing this out to me, but Tsutsumi actually also has a Mutant type quirk that overlaps with her Transformation type quirk. Tsutsumi's Mutant type quirk is visible in her "regular form", the mutation being her horns and her yellow eyes. Tsutsumi also has the ability to move through shadows. When Tsutsumi transforms her mutation becomes more prominent, and enhancing her abilities allowing her to manipulate shadows.
Aito Takao (@korissideblog)
Aito is another student that has two quirks because he had inherited both of her parents quirks, and they did not overlap with each other of fuse together, becoming two separate quirks for Aito. Aito's charm is an Emitter type due to it not impacting his physical appearance, and not requiring Aito to transform in order to activate. Aito also has a Mutant type quirk that she inherited from his mother, being her demon like horns and tail.
Edit: I mixed up the specific inheritance details so I fixed that.
Rin Tsukikage (@kamiart)
Rin is an Emitter type, because she absorbs energy from moonlight and uses it as she sees fit.
Edit: Thanks to the-heartbeat-hero for pointing out that Rin would also likely be an Accumulative type since she needs to accumulate the moonlight (which I also briefly brought up in the original version of the bio) in order to use it with her quirk.
Hiroharu Aki (@compoundhero)
Hiroharu is also a little tough to say, but I think his quirk would be identified as a Transformation type. The quirk type is a little hard to identify since Hiroharu does transform, but it could also be argued that the quirk uses emissions. But sense, from my general knowledge, Hiroharu would transform himself, I think it fits more as a Transformation type and not a Emitter type
Kiku Miyagawa (@cryptidanaphafsi)
Kiku's original lore page actually gives a lot of helpful details, making the designation of Kiku's quirk type to be very easy. Kiku's primary quirk, Grim Voice, is an Emitter type. Next is Kiku's smaller Mutant type being her grey skin, white hair, and piercing eyes.
Sumiye Gemu (@smol-hibiscus)
Sumiye is in a weird grey area when it comes to what her quirk type is. This is because she seems to have an Emitter type because she can transport items from games, but she also seems to be a Transformation type because her whole appearance changes each time she goes into a game, so it's hard to give a specific label to her quirk.
Tamashi Yoken (@eldritch-whispers)
Tamashi has an Emitter type quirk because she is able to use his quirk to read other people's emotions, and use their quirk in a way that could effect other's emotions.
Ayume Hikkido (@onibony)
Ayume has an Emitter type quirk, allowing her to convert glucose and blood sugar into special physical candies that can work as barriers or traps.
Edit: Thanks to the-heartbeat-hero for pointing out that Ayume would be an Accumulative type because she would need to accumulate the glucose in order to properly use it to create the barriers and traps.
Carlos Cordova (@pokeracer93)
Carlos has a Mutant type quirk, due to how he has permanent robot features and abilities, that he can not turn off due to how Mutant types commonly effect Mutant type quirk users..
Jimin Kim (@art-is-drawing)
Jimin's quirk type is actually listed in their bio, being a Mutant type quirk, which is shown by Jimin having a lizard-like appearance and abilities.
Class 1-Y
Pro Hero Miss Me (@dantelionwishes)
Ok this is going to need some explaining, but Miss Me is most certainly a Mutant type. I had to do a little bit of research, looking through Miss Me related posts to see how exactly her quirk works, and I think I have a good idea. But from information I learned here, it seems like Miss Me's quirk is actually just a mutation of the average persons instincts and reactions over injuries, allowing her to move fast enough to avoid any injuries that physically attack her.
Boni Mizumi (@flowersinorbs)
Boni is another character with two quirks. First is her primary quirk is an Emitter type, allowing her to create special orbs that can have a large variety of effects. Then is a small Mutant quirk that gives her some demon like features like small horns and a tail.
Momo Neko (@lintulady)
Momo has a small Mutant type quirk that gives her cat ears and a tail, as well as having a Transformation type Quirk that allows her to transform into a cat.
Mao Amai (@greyciees)
Mao has an Emitter type quirk that allows her to change the chemical composition of objects with her saliva.
Konekomaru Yoshino (@you-may-call-me-meme)
Konekomaru has a Mutant type quirk giving him the physical features and abilities of a cat.
Evan Satoru (@no1-horror-hero)
Evan has a Transformation type quirk, allowing him to transform his body into different eldritch-like ways.
Mitsumi Togan (@shinindiamond)
Mitsumi seems to have primarily a Transformation type quirk because of how she is able to transform her skin into a diamond-like substance, but she also appears to have a small Mutant Quirk causing her hair to constantly be made of this substance as well.
Ikuto Maekawa (@the-heartbeat-hero)
Edit: the-heartbeat-hero had brought up some details about Ikuto's quirk that I felt the need to redo his description, and since the-heartbeat-hero is still working out some of the details, I will likely edit this to be more accurate once the details are all set-in-stone. Ikuto has an Emitter type quirk that allows him to slowdown the heartbeat of others, but not himself.
Tokiya Iori (@skiduffle)
Tokiya has an Emitter type quirk due to how they are able to control how he and others are effected by the passage of time.
Yori Hayashi (@beetroot-bot)
Yori has an Emitter type quirk because she is able to transfer their injuries to others as well as transfer other's injuries to herself.
Edit: Alright thanks to beetroot-bot for pointing this out, but Yori stockpiles injuries, so that would make her an Accumulative type.
Kabane Higanbana (@imminent-soup)
Kabane has a Mutant type quirk because of the nature of his physical form being that of a zombie at all times.
Hina Mumei (@plutoeater)
Hina primarily has a Mutant type quirk that gives her physical features that resembles a moth, and an Emitter type that allows her to create a special dust from her wings that can cause dizziness, vomiting, hives, or even just a stuffy nose.
Kiyoko Hagane (@cosmic-goof)
Kiyoko is a Transformation type quirk, allowing her to transform parts of her body using metal she has consumed.
Jaye Rokuto (@zer0-10)
Ok, Jaye is probably the hardest to identify what his quirk type would be. I think the best fit for Jaye is an Emitter type, because although he does in a way "transform" by creating different clones, but because splitting apart while holding objects, living or not, also causes the duplication of those objects, by definition making it not a Transformation type.
Kurumi Yamashita (@nightseeye)
Kurumi is another character with two quirks that do not interact with each other. First is Kurumi's Emitter type quirk, allowing them to control and grow a variety of plants. Second is Kurumi's Mutant type quirk, giving them the look of a skeleton..
Doku Heiwa (@dokuheiwa)
Doku has an Emitter type quirk, which allows her to create poisonous gas and acidic saliva.
Tano Hoshizawa (@zedthebuggy)
Tano has an Emitter type quirk allowing him to create clouds of sparks in the air.
Naga Murasaki (@murasaki-naga)
Naga has a Mutant type quirk, making it so she can can stick to surfaces when activated and stretch parts of her body.
Murasaki Nendo (@genuinefauxthought)
Murasaki has a Mutant type quirk that causes her body to be consistently changing when experiencing pressure.
Hikari Kamino (@dantelionwishes)
Hikari has a Transformation type quirk, which activates when she "dies" changing into what I have been referring to as her Phoenix form, gaining the ability to create fire on her own.
Tsuki Hashimoto (@art-gally)
Tsuki has an Emitter type quirk along with a Mutant type quirk. Tsuki's Mutant type has it so her arms are separated from her body, being able to hover on their own, and these arms, along with her legs, are able to create the emission of strong blasts, like a rocket launcher.
ALRIGHT GAMERS! I wanted to make an au since making aus is fun and a lot of the other participants have had some really cool ideas.
I'm putting details under the read more since I put way to much thought into how this concept could work in the comeback timeline.
Alright if you couldn't tell from the drawing above I came up with a sort of zombie apocalypse AU.
Of course that isn't exactly the case, since the people that are infected are not exactly zombies.
First off, who is the most vulnerable to the virus?
It's actually people who have quirks, since the genes that allow a quirk to manifest usually leave people more effected by the virus.
Note that people who are quirkless are still able to get infected but they have better chances then people with quirks.
Second, how does the virus effect those infected?
The virus started in two "waves".
First was the wave that pretty much made everyone with an emitter or transformation type quirk lose the ability to use their quirks.
If you had a quirk related mutation, the mutation stayed, but any extra abilities other than physical changes to the quirk users body are unusable.
Then the second wave, the worse of the two.
That was when the infected started to pop up around the world.
The virus makes it so you lose a majority of the functions of your brain, like being able to think or feel, essentially just making you a walking corpse.
The virus doesn't make your body deteriorate, but the body is a lot more susceptible to injuries.
The virus also makes the eyes the same color as the sclera. This is mostly just so the there is a clear tell of who is infected and who is not.
I also wanted to point out some comeback characters who would probably be less susceptible to the virus, if not completely immune.
First off is Hibiki and Carlos. Since they are both heavily mechanical, they would probably have a hard time getting the virus since it is spread through the spreading of bacteria through things like saliva or blood (similar to some other zombie-apocalypse viruses)
Second I want to bring up Kurumi and Kabane. Since they are both undead they would probably not be as susceptible to the spreading of the virus.
Lastly I want to bring up Sumiye and Makoto. Since they are both at least partially made up of code makes them less susceptible to this type of virus.
The reason that the six students I brought up are likely less susceptible is because they are all biologically somewhat inhuman, even though they all are human in the sense that they have feelings are all are able to make their own conscious thoughts and decisions.
How and when did the virus start?
The virus started during a big break from school, at a time where most of the students had gone home to visit family. This is mostly so that the class could try and meet back up at UA or something like that, along with students who would likely not interact in a normal situation will interact since it is arguably the end of the world.
As for why the virus started, well I don't know.
Why the virus started isn't super important, its more of how will the students will survive in this sort of situation.
Alrighty so, this had started off as me drawing all of the currently revealed class 1-Y students (and their homeroom teacher, Miss Me) as memes, but that idea was abandoned quickly as I have not actually properly drawn any of the students other than Tokiya. So I drew mostly standing shots instead, with a few of the poses based on their character profiles. Nonetheless, I am very proud of all of these. Also, none of these are to scale to the actual characters' canon heights. It was probably obvious but I just wanted to say it anyways.
Anyway here is the list of OC Credits

What would a Hypothetical BNHA OC Comeback anime be like?
Hey y'all, Skiduffle here, and I'm about to over analyze details about the BNHA OC Comeback again.
Today I'm gonna be trying to figure out how an anime for the comeback would actually work.
Since this is gonna be long, my rambles will be under the read more.
Genre
Alright first (1) off we need to discuss what the genre this hypothetical show would be. There are two (2) possible answers that quickly come to mind for what the genre could be.
First (1) off there is shonen, just like base BNHA. Now I think this could work pretty well, but due to the large number of students with important roles, it would be hard to balance all of the characters without some characters overshadowing others.
Second (2) is probably the more obvious answer, but the genre would probably be a slice of life. Since a lot of slice of life shows have bigger casts. And even though some characters get more focus than others, they still give each member of their cast enough attention to be memorable (at least in most of the shows I've personally seen). A slice of life also just fits the chill vibe the comeback has.
Episode Format
I came up with two (2) separate formats to try help keep it so all of the characters have the same amount of time on screen as each other. These will be sticking with the slice of genre since
The first (1) episode format I came up with was pretty inspired from a different slice of life show that I'm a big fan of, that being Nichijou My Ordinary Life. I wanna preface this by saying I haven't watched Nichijou in forever so if I miss some details please let me know. For anyone unfamiliar, Nichijou is a slice of life anime based off of a manga with the same name, that was well known for its over the top comedy. Nichijou usually formatted its episodes with small, usually unrelated, situations using the shows absurd humor and over the top animation to create a comedic punchline. I think the hypothetical comeback anime could use a similar format, but likely not as dramatic as Nichijou, with different sections of the episodes focusing on different group or one on one dynamics.
The second (2) episode layout I came up with would lean more towards an episodic-style show. Each episode would probably focus on a different group of characters and the craziness they all experience throughout their day to day life as students at UA. The issue with this format is that it might be hard to have a character centric episode, due to the comeback having a large cast, with each student, along with the two teachers, being a protagonist in some sort of way, so that would likely mean the series would be 42 episodes, maybe 21 if we can split up the run time to have an A plot and a B plot, and that would take up a lot of the show's runtime, especially since not every anime gets 21 episode per season, many only getting 11 or 12. Even so, this is probably my preferred of the two options I personally came up with for episode format.
Overall Tone
For anyone unfamiliar, the tone of a story is the overall feeling the person hearing the story feels after the story is over. For example, Nichijou is mainly a comedy, so the overall tone of the show is lighthearted.
I think the best tone for the sort of direction the hypothetical comeback anime would be a more relaxed tone. This is because, even though the comeback does have its more meme-y moments, its more focused on character interactions. The relaxed tone might also help fitting some more angsty moments since if the anime was just comedy, a lot of characters would not be able to neatly develop, since the foundation is set up upon by jokes.
Final Thoughts
This section is mainly just to sum up all of the details I have brought up in the previous sections. First (1) off, the hypothetical BNHA OC Comeback anime (which probably needs a proper name) would be in the slice of life genre. The episode format would likely focus on the dynamics of multiple characters as they experience crazy misadventures in UA, with the occasional single character focus episode. Lastly the tone would likely be relaxed since the show is just a bunch of super powered high schoolers doing whatever, with the occasional sad or angsty moment.
