Mihoshi was in the prime of her life. She managed to land a side kick position at the Ground Zero agency. Dynamight /himself/ had scouted her and said the control of

To everyone's relief to say the support floor 'collapsed' was an overstatement. It had been severely damaged by the explosion though. They were all lucky the agency was in no danger of falling. A number of support techs had been injured, a few criticality. No deaths so far.

Mihoshi and the other sidekicks were set to crowd control and organization efforts. Every time the heroes pulled someone out from the mess a cheer went out among their coworkers.

Dynamight and Red Riot led the charge in digging people. The broad shouldered men moved

Destroyed walls and equipment with ease.

"Is that everyone?" His raspy voice demanded of one of the supervisors when he took a break to rehydrate.

Said supervisor was looking down a checklist. Muttering as he checked off names, "Yorabi and Desnoa are on vacation...Saynama was in the lobby...Midoriya had a mandatory free day--"

"Midoriya-san was in his office!" One of the intern techs interrupted. Dust clung to her pale face. "He stopped by for some notes he forgot!"

Everyone froze. There was no green haired man standing with the others or being tended to by parametrics.

That oddly still mask descended for a moment over Dynamight's face. Then without warning his face twisted into horrid scowl. He spun on his heel, practically running back into the building, Red Riot on his tail.

It took what seemed like hours to dig out Midoriya. As soon as Dynamight had him, the mess of blood and green was rushed to am ambulance before anyone could get a good look at him.

Clean up of the scene went on throughout the week. Many of those injured were already on the mend demanding they help. The news reported that Midoriya was in a coma.

Mihoshi wondered if that was true. She'd heard hushed whispers that the explosion had come from Midoriya's office. Theories flew across the media once someone leaked that to the press.

Some said it had to be a villain attack and accused the agency of being unable to protect the public if they couldn't protect themselves.

A rather dry debate had one side claim it was a building flaw and the other said it was a targeted attack on the one quirkless employee.

The leading theory was that there was an equipment malfunction. Dynamight's agency was full of heroes with volatile quirks. What would happen if one of Dynamight's gauntlets overloaded near combustible materials or could Pinky's acid have ruptured a gas line?

Mihoshi sat with the other sidekicks on the edge of her seat hearing muffled shouts from the conference room. A few members of the hero commission had arrived to evaluate the nastier rumors about a lack of security in the building.

Mihoshi scoffed at that idea. Her /parents/ had to pass a background check before she was allowed past any public sections of the agency. She had a few theories of her own. Midoriya's workshop had been a mess, likely a forgotten project exploded and caused a chain reaction.

A darker thought crossed her mind. Had Midoriya caused it himself? It seemed awfully convenient that it happened so soon after she confronted him. Did he snap and try to kill himself? Or was it a ploy to get Dynamight's attention? She rolled her eyes wondering if he'd

Wake up with 'amnesiac'.

Immediately she felt guilt hit her in the chest. She was a hero and she was being snarky about someone's potential suicide attempt! She needed to get it together!

So Mihoshi put on her big girl panties and decided she'd go apologize to Midoriya. Maybe offer to get him some help as a peace offering.

Ages in bios please. Imma start out right blocking people who follow/comment but have no age in their bio!

/**/

It'd been frighteningly easy to slip around hospital security—though the literal flower store's worth of deliveries and Hero Shouto arguing with the front desk certainly helped.

The modest bouquet of chrysanthemums in Mihoshi's hands would be a more reasonable present.

She decided she might gently suggest that Deku go on a date with Shouto, the greenette might not realize that the two toned hero was pursuing him. They'd make a cute couple...awkward but cute.

She found Deku's room easily enough, peeking at a nurse assignment board.

Dynamight's growling voice echoing through the ward was not something she expected. Mihoshi hid around a corner. She wanted to apologize to Deku, but not with her boss there!

Her hiding place happened to be close enough to hear what was being said.

“𝘠𝘰𝘶 𝘢𝘳𝘦 𝘪𝘯 𝘴𝘰𝘮𝘦 𝘥𝘦𝘦𝘱 𝘴𝘩𝘪𝘵 𝘯𝘰𝘸, 𝘋𝘦𝘬𝘶.”

“𝘐...𝘐 𝘬𝘯𝘰𝘸 𝘒𝘢𝘤𝘤𝘩𝘢𝘯. 𝘐'𝘮 𝘴𝘰𝘳𝘳𝘺.”

“𝘚𝘰𝘳𝘳𝘺? 𝘠𝘰𝘶'𝘳𝘦 '𝘴𝘰𝘳𝘳𝘺'! 𝘏𝘰𝘸 𝘮𝘢𝘯𝘺 𝘵𝘪𝘮𝘦𝘴 𝘩𝘢𝘷𝘦 𝘺𝘰𝘶 𝘴𝘢𝘪𝘥 𝘵𝘩𝘢𝘵?

𝘈𝘯𝘥 𝘩𝘰𝘸 𝘮𝘢𝘯𝘺 𝘵𝘪𝘮𝘦𝘴 𝘩𝘢𝘷𝘦 𝘺𝘰𝘶 𝘣𝘳𝘰𝘬𝘦𝘯 𝘵𝘩𝘦 𝘢𝘨𝘳𝘦𝘦𝘮𝘦𝘯𝘵?!”

“𝘉𝘶𝘵--”

“𝘕𝘰 𝘦𝘹𝘤𝘶𝘴𝘦𝘴. 𝘠𝘰𝘶'𝘳𝘦 𝘨𝘦𝘵𝘵𝘪𝘯' 𝘸𝘩𝘢𝘵 𝘺𝘰𝘶 𝘥𝘦𝘴𝘦𝘳𝘷𝘦 𝘰𝘯𝘤𝘦 𝘵𝘩𝘪𝘴 𝘴𝘩𝘪𝘵 𝘩𝘰𝘭𝘦 𝘳𝘦𝘭𝘦𝘢𝘴𝘦𝘴 𝘺𝘰𝘶.”

Mihoshi smiled to herself, proud of Dynamight for taking his power back. She didn't know if that meant legal action or not, but refusing the smaller man's demands was certainly a start.

A squawk from the room startled her out of thoughts. She'd obviously missed something.

“𝘠-𝘺𝘦𝘴! 𝘈𝘩-𝘐 𝘸𝘰𝘯'𝘵!”

“𝘎𝘰𝘰𝘥, 𝘐 𝘣𝘦𝘵𝘵𝘦𝘳 𝘯𝘰𝘵 𝘧𝘶𝘤𝘬𝘪𝘯' 𝘴𝘦𝘦 𝘺𝘰𝘶 𝘢𝘵 𝘵𝘩𝘦 𝘢𝘨𝘦𝘯𝘤𝘺.”

“𝘒𝘢𝘤𝘤𝘩𝘢𝘯!” 𝘛𝘩𝘢𝘵 𝘴𝘰𝘶𝘯𝘥𝘦𝘥 𝘭𝘪𝘬𝘦 𝘢 𝘴𝘰𝘣.

“𝘚𝘩𝘶𝘵 𝘪𝘵!”

A door slammed, and she held her breath as heavy boots trudged down the hall. She waited for the elevator doors to close before she approached the room. A quick glance, assured her no nurses were nearby. She knocked.

A small voice said, “Come in.”

Mihoshi braced herself before entering. Deku's red face looked taken aback to see her there. One of his arms was in a cast, and part of his curly head had been shaved for a bandage. She laid the bouquet down on the side table, next to the large vase of sunflowers.

“Hi, Midoriya-san...how are you doing?”

“He-hello Bombastic-kun.” He shifted a loud All Might themed blanket over his lap, “Well, uh, I've been better. Didn't expect my office to well...explode.”

“What's the damage?” She asked.

“Um, just a broken arm now. This hospital has a doctor with a healing quirk that amplifies calcium growth, so he healed the skull fracture yesterday. It's such an amazing quirk, and--!” He trailed off, “Sorry, I got excited...”

She decided to cut to the chase. “Dynamight-san was here?”

Deku went still, “...he was.”

Mihoshi sighed, and put on a gentle smile, “Did you think about what I'd said? It sucks that you got hurt...but this would be a good opportunity for you to...move on with your life.”

“Huh?”

“Well, Hero Shouto was in the lobby with I think an entire florist's stock. If you asked him for a job at his agency...”

“You're suggesting that I leave Kacchan's agency?” His jaw dropped open, absolutely aghast at the proposition.

“I think it'd be for the best.” She patted his knee. “I think you could live a full happy life away from Dynamight-san.” From what she'd read in that file, the two had always been near each other.

If Deku worked elsewhere, maybe he'd realize his blackmailing of Katsuki wasn't a way to live.

“...I see.” He then asked her, “Are they investigating what caused the explosion?”

Mihoshi blinked, “Um, yeah. I thought...do you not know what caused it?”

He shook his head, “No, I'd just sat at my desk and then...well 'boom'! I'm able to watch the news, so I know there's theories...”

“So you didn't do it yourself?” She smacked her hands over her mouth. How could she be so stupid to blurt that out like that?!

Deku's face lost all emotion. “I think I'm tired now. Please leave.”

“Midor—“

“Leave!”

She was quick to obey when she saw him reach for the call button. Maybe he had actually done it? In the elevator she shook her head, and sighed. The investigation would determine that.

Hopefully, he'd think about talking to Hero Shouto's agency.

/**/

Dynamight was too busy with the investigation and repairs to go on patrols with her. While bummed, she took it in stride. She worked with Pinky in that time, and knew she was in the close circle of Katsuki.

Patroling with Pinky, was a bit exhausting though—that woman was the definition of high energy!

She nearly fell asleep on the train home. That is until a few gasps went up among those around her. Phones pressed close to faces. An alert must have gone out.

Unfortunately, her phone had died before the end of her shift. She'd have to check the news when she got back to her apartment.

Mihoshi plugged in her phone the moment she got home. As soon as it hit 5% she turned it on, hoping to play some music as she cooked a late meal.

Ding!

Ding!

Ding! Ding! Ding! Ding! Ding! Ding! Ding! Ding! Ding! Ding! Ding! Ding!

“What?” She blinked down at her phone as alerts poured in.

Missed calls. Texts. News. Squeaks. Even the hero net had a BOLO streamed out. She clicked on the one from her mother first.

'ANSWER YOUR PHONE!!1'

'TELL US ITS NOT TRU11!!'

She'd sent a link to a HeroTube video. It opened to the serious looking anchor of HNN, “Breaking news straight from Dynamight's agency tonight. Investigators have now declared the explosion a murder attempt on the head analyst Midoriya made to look like an accident.

Investigators believe it may be due to his quirkless status that he'd been targeted.” Mihoshi gasped, how could someone do such a thing?!

“Security footage had been thought irretrievable due to a glitch caused by the explosion, but technical genius Hatsume Mei of Hatsu

Industries preformed the impossible and retrieved the following footage. Trace genetic markers left at the scene and compared to the national registry have confirmed this footage shows the suspect.”

The video switched away from the anchor to the footage.

'NO SOUND AVAILABLE' crawled across the bottom. Her blood went cold, and a kind of air crawled up her spine into her head. The footage showed someone hiding behind the shelves, hands pressing into the items there.

The video skipped forward, and showed that person interacting with Deku. Their hands resting on various things around the room...including flammable paper and equipment holding potentially combustible materials.

Mihoshi watched in horror as the video froze, and a square magnified around the person's face. A face she knew intimately. She couldn't get enough air. This-this couldn't be happening!

“Police and heroes are on the hunt for Rinya Mihoshi for attempted murder, and terrorism. She is a sidekick at Dynamight's agency, and her quirk is called 'timed bomb'. The explosive material she secretes can be later detonated at a time she deems.

Authorities warn civilians not to approach, and urge Bombastic to turn herself in.”

Her phone fell to the floor, shattering at her feet. “No-no-no-no-no-no-no!” She hissed out. She didn't do that! She had precise control of her quirk—she'd never—the room spun as she panicked.

What could she do? The news said her dna was found...she was set up! She had to have been.

Deku.

Deku must've framed her. He'd have had access to all the sidekick's gear, which often carried any emissions—like Katsuki's sweat.

She bit her nail. She'd been experimenting with her skin grease, that had to have been it. Deku used that. She just needed to tell the police and—

𝘽𝘼𝙈! 𝘽𝘼𝙈! 𝘽𝘼𝙈!

Someone was pounding on her apartment door.

Ugh I forgot about the lack of tweet chaining! Hopefully this update tides you all over while I'm busy with things IRL!

Mihoshi rushed to the door and opened it. It had to be the police. This was her opportunity to explain that it was all a mistake!

Before she could get a word out, a large body forced its way passed the threshold. Huge, hot hands grabbed her shoulders, and squeezed hard.

“Is it true?!”

She blinked up stupidly at Dynamight towering over her. A hat hung low over his forehead, beautiful red eyes blazing. A dark jacket strained over his arms, and she swore the v-neck shirt he wore had been painted on. Then she realized: he was in her home!

Her bedroom was only twenty feet away. She might just faint! “I-I—“

He shook her hard, “Use your goddamn words Bubbles! Did you try to kill Deku?!”

“No!” She quickly denied. “I'm a hero! I would never do such a thing!”

“You swear?”

She resolutely met his eye, “Sir, I swear on my life. It wasn't me. I think I'm being framed, and I know by who—“

“Not here!” He snapped a hand over her mouth. The sweet smell of nitroglycerin invaded her senses, she would never get enough of it.

“Listen to me. I got to get you out of here, somewhere safe.” Katsuki grabbed her wrist and dragged her out of the apartment. Luckily, no neighbors peeked out at them as they made their way to the parking lot.

He led her to a nondescript black sedan, nothing like the fancy cars he was known for driving. As soon as she sat down though she had to ask, “W-wait I have to call the police, and tell them my side!”

“Bubbles, that footage they scraped together is pretty damning.

They're gonna try and railroad into saying something stupid or confessing. The investigators won't even look at any other suspects or villains.” She couldn't appreciate the flex of his fingers on the steering wheel in the moment, too panicked by everything.

“They just want it wrapped up quick because Deku's quirkless and the press is breathin' down their necks.”

“I...” She tried to control her breathing. Mihoshi gripped at her hair, grounding herself with the pain. “What am I supposed to do?!”

The hero sped down side streets, moving further and further away from residential zones. She quickly lost track of where they were. “There's a detective I trust that's gonna take your statement—he's got a truth quirk. With him we'll be able to clear your name.”

Katsuki's voice came out clear and calm. She couldn't help but believe his surety. “Sir, I can't thank you enough.”

“Save your breath until we're done with this shit rookie.” Ahead, what looked like an old warehouse drew close. “We're here.”

Katsuki had a key for a heavy side door. He answered her unasked question. “It's a private gym. Shitty hair and I converted after the agency opened so we had a place to go all out at.”

She awkwardly chuckled, “I wish I was visiting under better circumstances.”

She imagined some one-on-one sparring...possibly pinned to the mat under the large man...their breaths intermingling, lips drawing close...

Lights were thrown on and momentarily blinded her. When her vision adjusted, she was able to take it all in. It looked like a normal gym with the addition of a concrete jungle on one half of the building.

There's what looks like a door to a small locker room near where they entered—a sink was running?

Katsuki leads her over to a chair set in the middle of the sparring area. There's also a small table there. “Sit down, he'll be here soon. Need a water?”

He pressed a cold bottle into her hands.

She nods, grateful, “Thank you.” No adrenaline left, Mihoshi fell back into the chair, feeling like a puppet with its strings cut. The water quenched the thirst she didn't realize she had.

Alone in the middle of nowhere with Katsuki sounded like a dream come true, but that dream didn't involve being a suspect in an attempted murder!

Her life was over!

𝘕𝘰, she shook herself, 𝘯𝘰, 𝘥𝘰𝘯'𝘵 𝘨𝘪𝘷𝘦 𝘶𝘱 𝘩𝘰𝘱𝘦! Katsuki knew she was innocent. He'd help her through this mess, just like she helped him get away from Deku's influence. Everything will be all right in the end. She just needed to have hope.

A squeaky wheel caught her attention. Katsuki pushed something to sit across the table from her which was oddly covered in black sheet.

Her brows furrowed, as she tried to understand. It moved—trembled really. Her eyes widened as she realized the thing was human shaped.

Why would Katsuki cover a person in a chair? This couldn't be the detective, right? Maybe it involved their quirk...

The blond hero smirked at her, and she swore her undies were immediately soaked. He grabbed the sheet, yanking it away. Her jaw dropped, she felt her face flush.

Dark orange ropes crisscrossed pale skin. A heaving chest, slick with sweat. Drool dripping down a chin from a ball gag. Red cheeks looked like plump strawberries with the freckles there. A tear-soaked blindfold hid what she knew to be musty green eyes. Headphones nestled on top

of green curls.

“What...” Her eyes trailed down to see a bean vibrator strapped to the straining cock between Deku's legs. “𝘞𝘩𝘢𝘵?!”

She started to stand, only for strong hands to yank her back down. Before she can react, she's cuffed to the chair

and something snapped around her neck. Her gaze landed on Katsuki looming over her, his face nothing but a still mask.

“Katsuki? What's going on? What—why the fuck do you have Midoriya like that?!” The hero had been hit by a quirk or-or it had to be an impostor!

She needed to get out of the cuffs, rescue the civilian and—cold stones settled into her stomach. Her quirk, her quirk wouldn't activate!

“Oh this?” He rumbled out a sardonic chuckle as he rounded the table back to the smaller man. Deku flinched when fingers traced his arm. “This is punishment for Deku. He broke the rules.”

The thing around her neck buzzed every time she tried to activate her quirk. “What rules? Who are you really?! Where's the real Dynamight?”

“Jesus fuck! Do you ever shut up?” The blond snapped. “You're worse than Pikachu after an icee! I am the only Dynamight!”

He reached up to yank down the ball gag. Deku gasped, swollen lips dripping spit, and whimpers now escaping. The Dynamight fake then pulled away one of the headphone cans. “Tell me Deku, what rules did you break?” The headphone was replaced before she could call out to him.

“I...I...” His voice came out breathy, “I worked—nnng, worked too much! And-and, ahn!” Deku writhed in the seat. “W-worked on my free day! A-ah!”

Katsuki gripped the curls at the back of Deku's head, cranking his neck back. The smaller man arched into the pull with a moan.

A vicious grin broke on the hero's face as he watched his victim writhe. “The rules are in place for Deku's own good. Little idiot would work himself to death otherwise. Fuck! He shouldn't have been in his office at all when that blast went off.”

Deku who could hear nothing moaned, “K-kacchan! Please, uhn!”

Her breath caught, “K-katsuki-san what...what do you mean?”

“What, got shit in your ears Bubbles? I'd planned that explosion so that it went off when dumbass here was at home.”

He easily hefted Deku from the chair, arms hooked under his knees—like Deku was some parcel. The buzzing vibrator strapped to his dick loud in the air. Katsuki kicked away the chair, attached to the seat is a monstrous dildo in Dynamight's colors glistening with lube.

“His punishment's just gettin' started.” Katsuki growled. When did he release his own cock? How was it bigger than the dildo?!

“But...” Her mind raced, thoughts couldn't form. “But it was Deku who did it...to set me up...”

Red eyes blinked at her once...twice...His drooling giant cock only an inch from Deku's gaping hole. “HAH?! You thought Deku did it? Deku who'd rather get hit by a bus than hurt a fly?”

He dropped Deku stomach first onto the table between them, and stared at her in wide-mouthed shock.

“Oof! I'm sorry! I'm sorry! I'll follow the rules, please daddy, please!”

Mihoshi cringed but soldiered on, she could have heard him wrong. Katsuki wasn't behind the explosion! “Sir stop lying for him! He wanted to get rid of me because I knew about the blackmail, and helped put a stop to it.”

“Blackmail...what fuckin' blackmail?” He scoffed, and absentmindedly slaps a sparking hand across Deku's ass.

“Deku blackmailing you into a job, and whatever sex thing is happening!” Mihoshi groaned.

“The anti-bullying campaign took away his leverage, he couldn't control you anymore. He framed me for the explosion because I was trying to convince him to stop blackmailing you!”

“Wait, hold the fucking phone—“

“You're free now Katsuki! You don't have to keep forcing yourself to be with Midoriya like this!” She'd be gesturing with her hands if they weren't cuffed to the chair. She could only hoped he listened and realized she was telling the truth.

Katsuki draped himself over Deku's back to lean toward her, hands smoking against the metal table. The bound man yelped at the sudden weight. A blond eyebrow crooked up, “You mean to tell me, that you thought Deku forced me to be with him. Not the other way around?

You weren't trying to 'save' Deku.” An ugly scowl now crossed his beautiful face, “All your little 𝘤𝘩𝘢𝘵𝘴 telling him to leave 𝘮𝘦 for his own good, you weren't trying to hop on Deku's dick...you wanted on mine.”

She blushed hard, this was a horrible way to confess, but no time like the present! “I-I've always admired you sir. You inspired me to become a hero! We work well together, and our quirks are complementary. I couldn't help but fall in love with you! I know I'm a bit younger but—“

She was cut off by braying laughter. Katsuki had thrown his head back, cackling. “You really thought I'd want you back?” Tears of shame burned her eyes. “There's only one hole I want to fuck, this one right here!”

“Ahn!” Deku's mouth flew open when Katsuki shoved his hips forward. “Kacchan!”

Her world was collapsing. How was this man a hero? “Then the explosion...you really...”

“Nng, I wanted you to back off what was mine, figured no one would look for your body if they thought you tried

to kill a poor quirkless freak.” He rolled his hips into a mewling analyst. “Hah, you made it—fuck—easier than I thought it'd be.”

“Oh, oh god...” She realized what he meant. The only reason she was privy to the disgusting show in front of her,

he didn't mean to let her leave alive. The man was insane. She squeezed her eyes shut before she could throw up.

It made the sounds worse. Skin slapping, gasping moans, and the entire table rattled from how hard Katsuki fucked the smaller man.

𝘽𝙤𝙤𝙢!

An explosion clapped through the air, and her eyes popped open again. Dynamight's eyes were on her, burning with mad delight. “Oi-oi-oi! No ignoring this now. You're gonna watch, and you're see why this tight little ass is the only one I'll ever touch with my dick!

You're gonna see how beautiful my Deku can be!”

“No! Please, I won't tell anyone just--”

He ripped Deku up from the table, again hooking his arms beneath his knees, and interlaced his fingers behind Deku's head in a full nelson.

The ropes strained against pale skin, firm and unyielding with the new position.
