Hiya! It's Been A Bit Since I've Done Fic Prompts So Here Are A Few Today. These Are From Bungo Stray
Hiya! It's been a bit since I've done fic prompts so here are a few today. These are from Bungo Stray Dogs which is new ik. Also a fun fact yesterday was my birthday. I'm not liking the responsibility and expectations that come with this age lmao. Oh, some of these have probably already been done but 🤷
What if the ADA switches places with the Port Mafia?
Oda is killed by someone different who had a grudge against him. Maybe they have a time rewinding ability? Idk but Oda didn't kill them sadly.
And instead of making his dying wish for Dazai to be a good person he asks him to avenge him and his kids.
And Dazai agrees...
They all have practically the same personalities (and abilities) just the Mafia who are now ADA aren't straight up murderous.
Just imagine the ADA commiting crimes
Like Ranpo coming up with the strategies, Kunikida as an executive, Yosano as an executive, Fukuzawa being a mafia boss, Junichiro being an assassin who is always up for murder, Naomi being a secretary who knows how to fight but is severely underestimated, and KENJI BEING IN THE MAFIA
Oh, mori isn't a pedo bc I think if Chuuya got to be the good guy he wouldn't let that slide.
Yosano still has the same backstory but maybe mori was a bit better but still felt pressure from war and the higher ups and stuff idk
Beast!Atsushi kinda idk if it would be Beast!Dazai sooo
Beast!Akutagawa but Chuuya is his mentor and Higuchi is like his partner. Kinda like Kunikida and Dazai
Chuuya used to be in the Port Mafia
Idk how or why Fukuzawa became the mafia boss???
Gin is in the ADA too
I think Tachihara would still have to be in the mafia?? Or maybe bc the ADA is always bumping heads with mafia that it would still be a place where he can gather info. Maybe the ADA is also under suspicion for something??
Idk wtf Hirotsu or Kouyou would be doing at the ADA tbh
Chuuya and Ango still have beef
What if Nakajima Atsushi tried to run away from the orphanage? Way before he was kicked out. What if Oda Sakunosuke found him?
Oda would have Atsushi stay where the other orphans were living.
Atsushi would also have a job at that diner or whatever it is.
And then he would help babysit his fellow little orphans whenever they arrived.
Atsushi saved the kids but he got hurt and lost control of his ability. He killed some of the Mimic members before passing out to heal from the bullet wounds. The tiger has never had to heal from anything so severe before. So, as the tiger had control she made him hide until he healed.
Oda finds him though with the help of the kids.
Idk what else :/
X-Files Crossover
Dazai Osamu as Fox Mulder and Nakahara Chuuya as Dana Scully.
Kunikida Doppo can be one of Mulder’s alien hunter friends or maybe two Scullys??
Atsushi and Akutagawa could be newbie agents that were assigned to the X-Files
Katai would definitely be one of the alien hunter friends
I don't think abilities should exist but if you could spin it in a good way go for it
Yosano could be a doctor or former doctor turned dominatrix friend that Dazai has
Ranpo could join the X-Files bc normal cases are boring or he could be an alien hunter friend
Fyodor is an alien
Sigma was abducted by aliens and doesn't remember anything from before
Chuuya had been abducted by aliens as a child but doesn't remember it. And thinks he was kidnapped by regular old people and hit his head or trauma blocked it out
Ango and Oda can either be higher-ups or alien hunter friends
Higuchi is a fellow newbie
Gin is in college or something

Fic prompt three! Or I think it's three... Anywho, it's a short one lol
✨Yandere Besties✨
I just want a one-shot of La-Brava and Toga Himiko meeting
Or maybe even a long chaptered fic.
Either way, I want them to leave kill the toxic men in their lives.
Put them behind them and have fun together. Bond and heal over their shared trauma of what happened with their quirks and crushes.
I want La-Brava to take Toga under her wing and teach her how to hack.
I want La-Brava to use her hacking skills to make it easier for Toga to get blood.
I kinda want them to run an internet cat cafe together lol idk!
Maybe they become vigilantes and go after horrible men and abusers.
I just want these yanderes to be besties and that is all.
Thank you for coming to my Ted-talk.
Here's my first fic prompt, it is short lol ~ MHA/BNHA
Nezu's Private Class of Gremlins
This fic is about the private class of Nezu's personal students. These students also have to have more than just smarts to be chosen. Or even considered really.
All Gen Ed classes are taught by Nezu instead until heroics and lab time. Though some of them probably tested out of some classes.
The most personal students Nezu has had before was two at a time. Those being Mic and Aizawa. Ectoplasm, and Power Loader.
These students get guaranteed spots as teachers at UA after they graduate if they want them. Just like Aizawa, Mic, Ectoplasm, and Power Loader.
Ideas for said students: Midoriya (obviously lol), Shinsou, Hagakure, Kaminari, Hatsume, Monoma, Kurorio, Shishida, and Kaibara.
After heroics the herolings go with Eraser for more extensive underground or twilight hero training. If that's what they want. While Hatsume (if you pick her) is in the lab for another extra hour.
Ecto takes over some of Nezu's principal duties when he's teaching them.
Aldera is gutted and reformed. All staff are either arrested and permanently lose their license, lose their license and could be reformed into getting them back, or permanently losing their license. All staff is replaced and the new additions are handpicked by Nezu.
All Aldera students are put in mandatory extra reform/rehab classes, mandatory therapy, and/or some even have community service.
This could also happen to any of the other gremlins past schools.
Midoriya Inko is a good mom. A lawyer? A cop? Idk but the nurse thing is getting old.
maybe this could be a civil war au???
The HPSC when they hear about his private class: Haha, I'm in danger
They are all still involved in the villain attacks bc they have heroics with 1-A and 1-B
Obviously all of these gremlins use the vents.
Vlad is simultaneously exasperated and terrified of them lmao
Power Loader is the same but he also loves them lol
And that's all, folks!
aizawa and izuku love shit talking together actually.
After the very awkward transition from teacher and student to colleagues, sit around in the teachers lounge in mostly silence. they work in silence -- well, mostly silence, as Izuku mumbles to himself.
"Keji, in my class?" Izuku says after hours of silence. "The pink haired kid?"
"The one that blew up the bathroom sink? What about him?"
"He's been very-- He's--" Izuku hems and haws. "He's been kind of a cunt."
Aizawa looks up from his computer, torn between shock and awe. "Midoriya."
"Well-"
"You're right, but you shouldn't say it." Aizawa picks up his coffee, mostly to hide his smile behind the rim, "You just call kids like that problem children."
I'm coming to you with another au! I just watched this anime and I'm reading the manga rn! I loved it but I did not appreciate the sexualization of teenage girls whatsoever :/ cool concept tho




High-rise Invasion AU
A crossover with this would be great and so interesting! But either way this au would be cool!
Imagine a whole lot of different characters caught up in that world?!
Some antagonists could be ‘Those Closer To God’ while some could be Angels and a few of your faves could be redeemed!
Remember relationships, friendships, enemies, and other things can be changed in fanfics! It doesn't have to be close to the original source material!
**Oh! Also, young (usually) = teen.
I feel like mori or fyodor (BSD), Klaus (TVD Originals), tom riddle (HP), vox, Alastor, Seraphim, Adam (Hazbin Hotel), muzan (Demon Slayer), AFO (MHA), metatron or azazel (SPN) and/or Whispers/Milton (Sense8) would be perfect for being the evil of ‘Those Closer To God’.
For Kusakabe role (in order to the evil those closer to god role): (for mori's pick Kouyou, Elise, or Yosano), Nikolai (BSD), Rebekah or Marcel or Elijah (TVD Originals), Lucius or bellatrix or umbridge (HP), (vox's pick valentino or Velvette), Niffty, Adam, Lute (Hazbin Hotel), and Doma (Demon Slayer), shigaraki/Tenko (MHA), gadreel or Meg (SPN), and Jonas (Sense8).
Ideas for enemy Angels: Meg and any other antagonists on (SPN), Daki/Ume and Gyutaro or any of the demons really (Demon Slayer), Zatara and have Zatanna as one of the MCs- that is some angst potential right there (YJ), Toga, Mr. Compress (MHA), Raoul (Sense8), tyler and matt (TVD), the death eaters (HP), and idk for Hazbin Hotel?
I think Cas or Adam (SPN), Giyu or Kanao (Demon Slayer), Conner or Zatara (YJ), Sun, Wolfgang (Sense8), Enzo or Alaric (TVD), Husk or Arackniss/Salvatore (Hazbin Hotel), Young Aizawa, Hawks, Dabi, Shirakumo, Young Mic (MHA), or Dazai, Ranpo, Chuuya, Atsushi, Akutagawa (BSD) would be great for the Sniper Mask role. Whichever you choose, the others are good for the good masks.
For the MC’s brother or Rika role I would recommend a lot of BSD characters starting with Jun'ichiro, Young? Dazai, Akutagawa, or Atsushi. Now the other recs are Young Dean (SPN), Young Aizawa, Young Dabi, Young? Hawks or Young Present Mic (MHA), Young Chuuya (BSD), Tanjiro (Demon Slayer), Angel Dust/Anthony (Hazbin Hotel), Young Dick Grayson (DC), Young Sirius Black, any of the older Weasley brothers (HP), Wolfgang or Will (Sense8), Young Damon (TVD).
For the MC or Yuri role (I will go in order to match with the Rika role) Naomi, Atsushi, Gin, and Kyouka (BSD). Now the other recs are Young Sam (SPN), Midoriya, Young Fuyumi, Kaminari, Uraraka, (MHA), Nezuko (Demon Slayer), Charlie or Molly (Hazbin Hotel), Young Jason Todd (DC), Harry Potter, Ron Weasley, Young Felix or Young Nomi (Sense8), and Young Stefan (TVD).
For the Mayu Role (again I will try and go in order): idk who to do for Naomi, Akutagawa or Lucy, Higuchi, Kenji? (BSD), Young Eileen (SPN), (for Mido's pick Shinsou, Todoroki, Uraraka), Mirko, (for Kami’s pick Shinsou, Jirou, or Todoroki), Toga (MHA), idk for Nezuko, Vaggie, idk for Molly? (Hazbin Hotel), Roy Harper (DC), Ginny, Hermione (HP), idk who for Felix? But Young Amanita for Nomi (Sense8), and Young Lexi, Young Katherine, Young Valerie? or Caroline? (TVD).
The Kuon and/or Rikuya roles (no order and these characters are similar): Zenitsu (Demon Slayer), Neville (HP), Megan, Zatanna, or Starfire? (YJ/DC), Young Sir Pentious or Young Emily (Hazbin Hotel), Kaminari, Komori, Uraraka, Hado, Aoyama (MHA), Atsushi, Young Poe, Louisa (BSD), Young Charlie or Kevin (SPN), Kala or Lito (Sense8), and/or Elena, Jeremy Davina, Bonnie? (TVD)
For the Doctor role (no order again): Crowley (SPN), Kunikida? Or Yosano (BSD), vox or Alastor? (Hazbin Hotel), Monoma or endeawhore (MHA), Quirrell or pettigrew (HP), Tamayo with Yushiro as one of her Angels, Inosuke, or Genya (Demon Slayer), sportsmaster (he doesn't get redeemed but his Angels do) with Artemis and Jade as his Angels (YJ), metatron with gadreel and Tessa as his Angels (SPN), and Kol, Katherine, or Pearl (TVD).
Also do what you want ofc but I think having quirks, supernatural enhancements, etc would make the world a little too easy but I'm sure it could be done right!
I might even do individual posts with certain fandoms since I love this au! Maybe even crossovers but that's less likely to happen <3


My next prompt!
Let Me Entertain Youuu~!
Villains kidnap and force those of UA and some other heroes (staff, 1-A, 1-B, Shinsou, and Hatsume– doesn't have to be all of them) to watch each other's memories
Like the MHA-verse type fics they are kidnapped and held in a theater but in this they are watching each other's memories not their lives in other universes
The main villain is inspired by Harley Quinn, is obsessed with Present Mic, and has a memory projection quirk
Kinda like Ms. Joke obsessed with Eraser but worse, more demented, stalker-ish, and even more harassment
Memories are projected on screen (the memory holder can either be awake or not)
They are bound by quirk suppression cuffs (they work on mutations like Eraser's quirk, for example Ojiro's tail would lay limp and he wouldn't be able to move it, Shouji wouldn't be able to produce extra body parts, and Tsu can not use her tongue like she does all prehensile like)
Some of their worst memories are shown and some of their happiest are shown too
They see how they affect each other and what needs changed
This sets off a lot of events during and afterwards. Like Aldera being shut down, endeawhore being arrested, confessions being made, as well as rejections, all around secrets are outed, and just stuff like that
Maybe show the perspective of those who weren't kidnapped trying to find those who were??
Anyway... TRAUMA BONDING!! Lmao
Maybe 1-B can see what the USJ was like?? How everyone outside of class 1-A treats them bc the villain attacks?? idk
Seeing certain discrimination of others how they're treated, how they deal with it, and how it's affected them
I ran out of more ideas for this one...
