Dr Chisaki & Monsterhaul x reader (Dr Jekyll and Mr Hyde AU) by IsabeauWolf
Fandoms: 僕のヒーローアカデミア | Boku no Hero Academia | My Hero Academia (Anime & Manga)
08 Oct 2025
Tags
Summary
No matter how godly Kai Chisaki, Overhaul thinks of himself, the true savior of mankind. He's still a man, a man with desires, needs, carnal and sinful, impure thoughts swimming in his head of you.
Locking his desires, his secret pleasures of watching you from afar. Telling himself he can't have you yet.
Little did he know, that by locking away the remaining fragments of his human heart left behind in the darkness; it would become his undoing.
Awakening and feeding his inner beast, his inner monster. The darker, animalistic, hungry, lustful, depraved and greedy, black hearted, twisted version of himself.
Monsterhaul.
The beast slept, deep inside of Kai Chisaki. The need to feel you in his arms grew and grew, the bitter jealousy and rage the monster felt whenever any male dares wonder too close to you, their chosen mate and female, their perfect pretty one.
Modern retelling, twist on the Classic "Dr Jekyll and Mr Hyde."

Summary
Kai Chisaki saw a chance to escape that shit hole of an orphanage and he took it. Using his quirk during room changes and ran, he ran and ran until his body gave out.
A she-wolf finds him and brings him home. She couldn't bare to leave him, this child. She doesn't even know his name and her inner beast has already claimed him as her own son.
The Bliche and The Shie Hassaikai clans have been allies for years. It makes sense for Lady Sara and Pops to arrange for Mary Bliche and Kai Chisaki to become married in the future. Two years fly before tragedy strikes the young Kai again. Losing his adoptive mother, and his betrothed is sent away from Japan until she becomes of age and returns to Japan.
Mary returns to Japan to fulfill her mothers promise to become Kai Chisaki's Wife. Not knowing that her life will change forever when two more men, two villains become obsessed with her as Kai. Tomura Shigaraki and Dabi. Can these villainous men handle Mary and her inner wolf? The Granddaughter of The Great General and Rival to All For One.
The push and pull, life and death, sanity and insanity, darkness and light; who says villains don't get happy endings?

Overhaul's guide to survive your three year old by 404_error_unknown_404

Summary
Kai was completely out of his depth in this. Surely Pops had to have known this right? He wasn't built for this, children were too confusing and he was not the right person to be taking care of a traumatised three year old.
Life is funny how it turns out though and healing is usually easier with someone by your side.or How Chisaki Kai warmed up to Eri

Summary
In a society of Hero’s one would believe everything was fair and just. However it was far from your utopia that was presented to the masses. For there were those like you who demeaned by the hero society to have the quirk of a Villain. Cast out by peers and by adults alike, you were going to prove them wrong. You were going to prove that even if people and the world judged you as a villain that you could still be a hero. On the way you’ll learn friendship, love, and the real price of being a hero.

Quiet by 404_error_unknown_404

Summary
Eri was a happy, normal enough child so when she was quiet Kai tended to become suspicious. He did enjoy the quiet but knew that if he didn’t nip this in the bud it could get catastrophic and lead to having to deal with a moody 4 year old for a possible week (surprisingly she could hold a grudge if she really wanted to, it would be impressive if it wasn’t him that had to deal with the outcomes).

Love as a Practical Matter (and Means of Escape) by AgronawithLove

02 Aug 2023
Tags
Summary
Grabbing her hands, you pressed your forehead to hers as well as you could with your long face and her horn in the way. “Eri, do not worry about me, okay? Don’t worry about anyone but you. Just focus on yourself and getting old enough to get out of here.”
“But, I love you,” the child pleaded. “I want you to come with me.”
You stilled. She loved you. You were a part of why she was rotting in this nightmare gang and she loved you. Why? Because you tried to do something for her once? Because you comforted her a little when you could?
(Or, heaven and hell are both found in other people. For you, in the embrace of two golden-eyed men.)

Summary
He breaks the silence first, hardly above a whisper, looking at you again like he could tell exactly what you were thinking. “Kai,” he offers. You almost miss it, lost again in thoughts of stitching a particularly horrid gash, cocking your head slightly to look up at him. He clears his throat. “Kai Chisaki.”
This time, you’re sure your smile travels all the way to your eyes, giving you away. You offer your name in return, barely above a whisper; a give and take, a pattern quickly forming between the two of you.Or, Kai Chisaki saves your life, and the universe insists on bringing you back to him.

Summary
Fantastic. Absolutely fantastic. Just their luck, she assumed. Of course, it would pick tonight of all nights to go out. The coldest night they’ve had so far this season and they don’t have heat. Ugh.
It was five in the morning and it was also so incredibly cold during these winter months. There was a chill that ran down her spine as she sat up and scratched at her head, stretching and shivering as she let out a huff, seeing her own breath, to which she grew annoyed. She hugged herself, rubbing her hands up and down her arms to try and get warm, to feel warm, though of course not even that worked.

It's Chisaki Kai's birthday! Or so...his simple minded lackeys think it is. They really wanted to do something special for their boss, and the present is untraditional, to say the least.
Or
Chisaki has a night with a sex worker, has unprotected sex for the first time, cums way too many times, and indulges in being touched

To Read Your Lips by BatBonez

Summary
“Kai, do you trust me?” He asks again, voice soft as if afraid to disturb some unknown force in the quiet of the room around them.
If he was to ask Kai that question several months previously, he would have said no immediately, but that’s no longer whatever their relationship has morphed into. Trust is hard for Kai to give, he’s given his trust to one to many people in the past that have used it against him, but with Dabi… with Dabi, their mutual understanding of one another has formed some twisted form of trust. He leans forward so their foreheads are pressed together.
“Probably more than I should allow myself.” He breathes against the other's lips, biting softly at them.
