Summary
The blonde hero lets out a small laugh “I like this side of you, this awkward, nerdy and embarrassed shit is fun”
The singer whips out another cigarette from the box, dangling it in his lips as he looks for his lighter. “You don’t even know me enough to know what sides of me to like.” He looks up from searching to find Katsuki’s hands cupped below his cig. The blonde snaps his fingers, sparking and lighting the cigarette instantly. Deku lets out a small “Thank You” and resumes his smoking.
Katsuki’s leans down so close, hand resting just above Deku’s head.
“So let me get to know you”
Pro Hero Bakugou Katsuki finds himself slowly captivated by none other than Midoriya Izuku: A quirky, adorable, and frustratingly mysterious parapsychology major obsessed with music. -

moonflowers grow in the dark by Lulululucy09121

Summary
Izuku has many names. Izuku Midoriya, Izuku Shimura, Izuku Chisaki, Ghost, Deku and Moonflower.
Izuku Midoriya is a high school student. Izuku Shimura died in a car crash. Izuku Chisaki is the so called son of a Yakuza boss, Overhaul. Ghost is the second lieutenant of the Yakuza. Deku is a hero student in the analytics course, and Moonflower is Stain's protégé, a member of the LoV, and a vigilante who's been employed by the heroes.
The only problem is keeping all these identities separate. When you're working with villains, heroes, Yakuza, and the smartest person (?) in Japan, that becomes very hard. It's double especially hard when you're expected to be in four places at once, all with conflicting goals. It's triple especially hard when All for One is causing absolute chaos amongst everyone.
How long can Izuku keep up?

Midoriya Izuku didn’t stand out, not in looks, quirk or even exams. He was easily looked over, without a second glance. He could just disappear
Life would be easier for him if the yakuza stopped trying to involve themselves -

Summary
Kai picked up the other phone, wondering what to make of it all. During his short career cleaning other people's homes, he'd come across countless clues and pieced many untold stories of crimes and mishaps back together for none other but himself, but this felt different. Almost personal, in a way. None of his jobs ever had something to do with Pops. With his men, sure, but not with Pops himself.
------
Imagine an AU in which Kai Chisaki aka Overhaul was never adopted by the Yakuza, but discovered for his talent of cleaning (and removing evidence) many years later. He's called in for a new job, but this time, it's about finding evidence, not removing it. And also about a little girl being the key witness to a murder case, and a hero being the prime suspect.A murder mystery told from the view of a germaphobe with the emotional range of a very annoyed rock that I will keep beating with a stick until he feels something.

[Overhaul]
Take care of yourself.Izuku automatically looked at his text. A habit he’d make sure to get out of now that his stomach did flips at what he read. Gods, Izuku was criminally bad at reading tone through text. Anger? Disappointment? Resentment? He couldn’t tell and that part bothered him the most.
He clicked on the notification to open the secure line and hesitated, his thumb hovered over the reply button with no idea how to respond. He typed, deleted, retyped, deleted, and retyped again:

Summary
I just wanted to write something really fucked up okay?
Shigaraki has trust issues and Dabi is a dick, I apologize to anyone else who loves Dabi.
And Hawks.
And Shigaraki.
Magne doesn't die in this one BTW, she'll just be a background character I'll probably forget to write in.
Overhaul is surprisingly sweet and gentle in this but he may or may not have his mean moments. -

Summary
Merely days after getting attacked by a sludge villain, Izuku Midoriya is kidnapped by the Yakuza for his quirklessness. When the repercussion of not doing what he’s told is a little girl getting experimented on and tortured, Midoriya decides the only option is to obey regardless of consequences.
One of these long-term consequences somehow became seeing his kidnapper as a father figure and not knowing how to make it stop. Overhaul’s constant praise certainly isn’t helping!!

Summary
“Taking care of somebody else made me feel good. Like discovering you’re more than you thought you were. More even than you hoped to be.” - Bette Greene
In another world, Chisaki Kai is a ruthless, cruel man who stops at nothing to rid the world of quirks. In this one, however, he draws lines: one being Eri. He cares for her, treats her like his own daughter. And for his precious daughter, he needs somebody to help care for her, somebody who isn’t one of the Eight Bullets or a member of the Yakuza.
Enter one Midoriya Izuku: quirkless, protective, and the perfect candidate to be her babysitter. Now if only Chisaki could just stop worrying about the boy, too, that would be great. (No, Chronostasis, he does not have ‘paternal instincts,’ thank you very much!)
Or: Midoriya Izuku (accidentally) turns the Yakuza into the
goodmorally grey guys.Series

Summary
Tomura started streaming, give or take, a year ago.
Having his own community felt... cozy. In a way. Nice.
He had to find a job real soon, though. Babysitting for Chisaki mostly let him ogle the man, interact with Eri, and have a couple of snacks here and there, but Tomura needed a stable income.
Then one day a viewer suggested an unexpected job for him. Can he graduate another time? He'll have to actually interact with people this time around... Ew.

Summary
Deku felt like he was cursed. There was no other explanation for the destruction that followed him wherever he went or whatever he did. It didn’t matter how much he attempted to act with the best intentions for everyone's sake. He would always fail and cause others’ demise because that’s what he was; a useless quirkless good for nothing. Even Katsuki had told him so and now he has lost everything.
“And who might you be?”
He lifted his head from the soil it was buried in and looked at the masked man with golden eyes. He was on one knee and one of his hands was behind him like he was hiding something from him.
Deku sniffled as fresh tears streamed down his face, “I’m Deku.”
Or,
Ten-year-old Izuku is provided with a new home and grows up under Chisaki’s guidance.
