Mirko found the inside of the mall an absolute wreck, debris everywhere, bits of wall broken off and windows smashed into bits all along the floor.
She kept her eye out for the villain that caused the trouble, keeping in mind Izuku's description. The kid had done good distracting him. There hadn't been any injured when she had arrived. Though the police had mainly seen to that. They were surprised at her quick reaction time, and had informed her that there was a major attack.
She decided not to tell them that her arriving was just a major coincidence.
It was a stroke of luck that she found Izuku even after all the hullabaloo of having to act like she was responding to the crises. She had pleasantly noticed that he hadn't broken any bones, and it seemed he was the one responsible for keeping his date and his teacher safe.
"Where are you?" she muttered, looking around as she stalked forward, deeper inside.
With a sudden twist, Mirko flipped to the side, avoiding a thick gooey tentacle that had aimed right where she had been.
As she landed, she looked upwards, and saw the source of today's trouble.
"Damn it. Another pro? This has been a waste. Guess I ought to bail…"
The creature speaking was just as Izuku described, a slime quirk user. He seemed to be scowling as hung from the ceiling upside down.
Mirko almost just jumped up there and kicked him. But she wanted to find out just what was going on.
"You up there, I got questions for you."
"Can't promise I'll answer 'em bunny girl. But ask away."
"You seem pretty nonchalant for causing so much trouble. Shouldn't you be a bit more nervous considering you're about to go to jail for a very long time?"
"Better heroes than you have tried. And I've done waaay worse than this."
Mirko couldn't help herself from grinning. Oh, this guy wanted to fight! Better heroes than her? Pssh, those didn't exist. Not since All Might's retirement anyway…
"Alright, slime boy, I just want to know one thing before I kick your ass. You the one sexually molesting Izuku Midoriya?"
That question didn't get the response she expected.
"WHAT? Fuck no! I don't even know who that is! But it sounds like you're after my sister, which funny enough is why I'm here too. She's latched on to that short green hero, Deku. I was trying to get her out, but things," he looked about with a smile on his face, "Got a little out of hand. My bad."
Mirko found that information rather interesting. Quirks in families were usually pretty similar. If this guy was after some other slime villain… and who was Deku?
"Well, I just needed to know. That's enough chit chat for now, though. I'll let the police interrogate you thoroughly after I thrash you!"
She exploded into the air with a powerful jump, right up next to the villain. He didn't seem too phased as he brought up his arms to defend, and four more tentacles erupted from his back.
The fight wasn't Mirko's toughest, but it had been one of the most frustrating she'd ever had. She was fast enough to dodge all of the slime villain's attacks, but whenever she countered, her attacks just didn't seem to do anything. Like the kid had said, he could change the properties of his slime, making him like rubber at some times, water at others, and steel when he wanted to attack.
In the end, it was largely a stalemate, and the villain ran off. Any other day, and Mirko would have been pissed.
But today, she was more focused on the green-haired boy she had agreed to mentor.
When she emerged from the mall, she told the police everything she knew about the suspect and let them secure the area, looking to see if there wasn't anything left behind by the villain.
Izuku and the other two were still there, waiting for her. They sat close by with blankets and hot cocoa provided by the police. Mirko wondered if she should introduce herself now, or wait. Things hadn't exactly gone to plan. She rolled her shoulders and decided to introduce herself, and set up a time to meet him. It'd have to be quick though, night was already falling and she imagined the kid was tired.
As she approached, Midnight was the first to notice, and she gently tapped the two students to get her attention.
"Hey there, mind if I talk to Izuku for moment?"
"Not at all," Midnight replied. "Young Midoriya here was waiting to talk to you anyway. He's a big fan."
"Hey, Midori," the pink-skinned girl said, "You mind if I go ahead and get back to the dorms? Its been a long day."
"Sure, you go ahead Mina. I'll see you later, ok?"
The boy was kissed on the cheek, and immediately became flustered. Mirko raised an eyebrow at that. The pink girl- Mina, Mirko supposed, smiled brightly at him.
"That wasn't the kiss I owe you by the way, it was just for being so amazing in there."
With that, Midnight escorted her to the police to explain she would be going back to the UA dorms and left the young boy alone with Mirko.
"Cute girlfriend you got there." She said.
That caused the boy to blush and look down bashfully.
"Mina isn't my girlfriend… this was actually our first date…"
"That so? Well, it'll be one cool conversation later down the line. Listen, Izuku, All Might already told you I was your mentor for the work studies, right?"
"Oh! Um, yes!" He stood up and bowed politely.
"No need for that. I'm not much into formalities. My name outside of work is Rumi Usagiyama, call me Rumi."
The boy blushed, and for a moment Mirko wondered if this was really the boy that she had seen dash out of the mall and break his bones trying to win the UA sports festival. He seemed so meek and timid. Was this really the same kid?
"Um, Ms. Mirko, did the villain… say what he was after?"
Mirko quirked an eyebrow, was that what he really wanted ask, or was he being made to ask that question somehow?
"Yeah, said he was trying to kill some hero named Deku. I've never heard of that hero, though."
"Deku is my hero name."
Mirko felt like she was beginning to puzzle things together. The villain was after Izuku, huh? She remembered the brief conversation between herself and the villain and he said that Mirko had mistaken him for his sister. Could that be the mystery villain UA was currently after? It seemed likely. She needed to get back to her home and start making some calls.
"Well, Deku, from one hero to another, good job. You held him off until professionals arrived, and kept everyone from getting hurt. Not many heroes could ask for much more."
A certain transformation seemed to take over the young man, as determination filled his eyes, and he clenched his fists. He straightened his back, and Mirko felt as if she was talking to a completely different person.
"I should have beat him. Captured him. I'll defeat him properly next time. I'm sorry I didn't today."
She smiled. There was the kid she had been looking forward to meeting.
"Agreed. But he's a slippery bastard. Got past me too. Our quirks aren't really optimal for capturing guys like him. But don't you worry. We'll be prepared next time"
"We?"
"Damn straight. You're my mentee, now right? And this guy is after you. So, for our first assignment, we're going to hunt down this bastard and throw him in jail! Sound good to you?"
"Yes Ma'am!"
"Call me Mirko… or Rumi when we're off the clock. None of that Ma'am stuff. Makes me feel old."
"Y-yes, Ma- Mirko!"
"Atta boy!" She patted him on the shoulder, smiling at his timidity trying to surface and his obvious struggle to push it back.
She gave Izuku her address and told him to arrive there next weekend. He asked for his phone back, but Mirko made an excuse to keep it. Not a good one, but the boy was way too timid to reach into her cleavage to get it back. After talking to the police one final time, the young hero went back to his dorms at UA, and Mirko headed towards home.
As she walked her way home, she pulled out Izuku's phone and gave a deep sigh.
"Let's see what's going on with you, boy."
She was both relieved and disappointed to find that the young man hadn't bothered to password protect his phone. Relieved, because it made everything much easier, and disappointed because she believed that in any other circumstance, he should have been more careful.
She checked his messages first, and nearly fell face first on to the concrete below.
Two girls by the names Ochaco Uraraka and Momo Yaoyorozu had sent him dozens of nudes. Not just nudes, though, full on porn clips too. Videos of them making out naked, licking each other out, using dildos on each other, and more. They also sent plenty of videos and pictures of themselves solo, their faces very visible. They weren't even trying to hide who they were!
But the messages they sent were the most curious thing. And Izuku's responses weren't something you'd figure a horny teenage boy to say.
At first, Mirko's thoughts were she'd stumbled upon some teen Casanova and his paramours, but she instantly rethought her position as she examined the texts.
Momo Yaoyorozu: I can't wait to suck your dick today.
Izuku Midoriya: Please, don't
Momo Yaoyorozu: Oh Izuku, you know you can't say no.
Izuku Midoriya: We just did it last night! Please, don't make me do this.
Momo Yaoyorozu: You've done so much already, why not stop feeling sorry for yourself and indulge yourself with me? I love you so much Izuku! 3
Izuku Midoriya: Stop playing with people's lives! This isn't right! Please, find some decency in your heart.
Momo Yaoyorozu: All I have is love for you, my sweet Izuku. Now meet me behind the dorms at 9pm ready for fun. If you aren't there… well… I'll probably get really sad.
Mirko found most of the messages were the same. One of the two girls initiating, sending explicit photos and videos, and Izuku begging them to stop. Sometimes, if the boy pushed back too much, they'd both reference "getting sad" and that for whatever reason stopped Izuku's protestations. It could be seen as the boy playing hard to get in some strange role reversal… but Mirko didn't think so.
The villain she'd fought that had a slime quirk, could (according to Izuku) change shape into people. When she had accused him of sexual molestation, he'd been offended and claimed that she was speaking about his sister. And when asked why he was attacking, he said he was trying to retrieve her from Deku… who was Izuku.
Mirko tapped her chin in contemplation as she reached her apartment.
The sooner she found out who this villain who attacked the mall was, the sooner she'd find out who his sister was. And she suspected that this sister was the mystery villain the UA teachers were looking for. From All Might's suspicions her quirk might have something to do with passive monitoring of people and mind control. How that worked with a slime-based quirk she couldn't put together just yet.
As she opened the door to her apartment and slipped inside, she felt a sense of unease. Her rabbit ears twitched and her nose was filled with a strange odor. A smell of lavender and sweat.
She jumped over her coffee table as someone came from behind the door and shot out a burst of some kind of gas. Mirko landed with grace on the other side of her living room and squared up, ready to face whoever was dumb enough to attack her in her own home.
Her eyes widened as she saw Midnight, one hand on her hip and smug expression on her face.
"Midnight? What are you doing here? And why did you attack me?"
She didn't respond. Instead, she began to strip off her clothing. First her top, then her pants, then her shoes. Mirko wasn't sure what was going on. But she was starting to suspect… was the mystery villain controlling her actions?
In a matter of moments, Midnight stood in her underwear. Unsurprisingly it was lacy black lingerie, and began to activate her quirk, her somnambulist gas filling Mirko's apartment.
Finally, Midnight spoke.
"Sorry about this Mirko. But you know too much."
"But not as much as I should." Mirko responded.
She decided she'd figure out what was going on after she dealt with Midnight. With a side-flip she covered the distance and delivered an axe kick, trying to deal one solid blow to end it. But she wasn't fast enough. Midnight was able to jump out of the way and deliver a kick of her own right on Mirko's chin. It stung, but Midnight had no strength enhancing quirk, and as such she was only as strong as any average athletic 30 year old woman.
Mirko responded with a roundhouse kick to the woman's chest, knocking her back into a bookcase and causing it to fall on top of her.
Midnight didn't stay down, to her credit. She pushed the bookcase off and began throwing the books at Mirko. They weren't very effective throwing weapons, but they did royally piss the rabbit hero off. What the hell was even going on?
She jumped forward and sunk a solid punch right on Midnight's chin, knocking her over the couch, landing with a thud on the floor. Mirko didn't let up and made to restrain her, but as she moved, she began to feel a bit sleepy.
She had a hard time keeping her eyes open as she reached Midnight. She came back to reality when the older heroine kickflipped herself back to her feet and landed a solid combo on her.
"Can you feel it, Mirko? My gas doesn't work as well on women, but it still works if given enough time. You're getting veeeery sleepy. And who knows what kind of fun we can have while you sleep~. You are quite the sexy bunny after all."
Mirko was getting tired, but all she had to do was knock Midnight out before she succumbed. She looked over the older heroine before something clicked.
"I get it now. You aren't Midnight… but that is Midnight's body."
Her words caused Midnight to step back, her eyes wide. Mirko saw that got a reaction, and began piecing the puzzle together.
"You… you're like a parasite. Not a shape shifter… but someone who takes other's shapes. Their bodies. That villain I fought mentioned something like that. That you'd latched on to Izuku. He mentioned getting you out… what he meant was out of the boy's body. And you've taken over the bodies of other's at UA too. Momo Yaoyorozu and Ochaco Uraraka, am I right?"
Midnight didn't respond for a moment, then she cursed.
"Damn it, Goo! Why can't you keep your damn mouth shut!? Well, whatever, its not going to matter much longer anyway, Mirko. Once I take you over, I'll be taking over most of UA. If Izuku thinks he's ever getting rid of me he's sorely mistaken."
Mirko knew now wasn't the time to interrogate whoever it was that had taken over Midnight, but she had a lot of questions for after all this was over. She shook her head, trying to keep her eyelids open.
"Sorry about this Midnight… I know you're in there somewhere. But this is gonna hurt like a bitch."
"You're talking pretty tough for someone who can barely stand."
Mirko didn't dignify that with a response. She leaped forward with speed, leading with a drop kick. Midnight stepped out of the way, but wasn't fast enough to avoid a whirlwind kick follow up.
Mirko was relentless, kicking at Midnight's torso and head at every opportunity, trying to knock her out without hurting her too bad. Midnight wasn't a terrible fighter, but she wasn't up to Mirko's standard. The fight was short and brutal, and the somnambulist gas was getting thicker every moment. As the fight went on, Mirko's apartment became absolutely destroyed. Every time Mirko missed a kick, it crashed into the furniture, splintering apart.
Midnight scowled as she wiped away the blood dripping from her chin, eyeing up Mirko with a bruised and beaten face.
"Why won't you just go to sleep already!"
"I could say the same about you!"
Mirko delivered a solid hit on her midsection, and followed it up with an uppercut to chin.
Midnight finally fell down, and stayed there.
With haste, Mirko opened the door to her apartment and leaned outside the balcony, coughing up gas. She hoped that if the gas dissipated in the night air it might become less potent. She brought out her own phone and quickly dialed All Might's number.
"Mirko? Is that you? How did meeting young Midoriya go? We heard about the villain attack. What happened? Midnight still hasn't returned. We're getting worried."
"Listen quick! I'm about to pass out. I've figured it out, but I don't have time to talk. Get to my apartment ASAP. Midnight is here. She's not herself. Capture her and put her in a priority 1 cell. I'm serious! No bars or cracks! I need you to- to…"
And that moment, Mirko finally succumbed to Midnight's somnambulist gas.
Izuku found the day after the mall incident had given him some small celebrity among his classmates. Kirishima, Kaminari, and Sato especially were interested.
"Wow, so you fought alongside Midnight and actually saved her?!"
"No, way dude, you fought another villain? You have the worst luck!"
"Man, Midoriya, you sure are manly! Not even in your work study yet and you're already working with the pros!"
Izuku tried to keep them all placated, assuring them all that he hadn't really done all that much. After all, the villain had gotten away.
Jiro, still at her desk, but curious about Midoriya's exploits, called out from across the room.
"Hey, Midoriya, what was that villain's name, anyway? He on any of the known wanted lists?"
"Oh, um… no I don't think so. He said his name was Goo, but I'd never heard of him before."
Kaminari let out a laugh.
"Well if Midoriya's never heard of him before than he must be new! He knows every hero and villain in Japan!"
"Well," Midoriya replied sheepishly, "That's not true. I don't really keep up with villains. And a lot of the really successful ones don't show themselves in public too often."
Damn straight.
"Settle down, all of you. It's time to start."
Mr. Aizawa sent everyone back to their seats to begin the days lesson. Izuku did his best to focus on school, not wanted to fall behind or miss anything important. But it was difficult when he felt as if so many other important things were going on.
Brain-Jacker had taken control of Mina and Midnight yesterday. And he was worried about what that meant. Mina was still acting like herself, much like Momo and Ochaco did during their early infections. Though now both had been released from direct control. Midnight hadn't been seen since yesterday, which Izuku found strange. What had happened? Had Brain-Jacker infected anyone else? He tried not to think about it and instead focus on his plan, but his head was too full of thoughts and his heart too full of emotions.
He spent the rest of the day working on writing without looking at his notes. Brain-Jacker didn't catch on to what he was doing when he looked down to assess how well he was doing. Which, he found, was poorly. He could read his writing only barely, and he doubted anyone else would be able to tell what he had written. He decided he'd have to practice on his own in his room to speed up the process.
Most of the other students continued to ask about the mall incident sporadically, even a few people from class B and some from outside the hero course. He hadn't realized it was such a big deal, but he found most people were curious because he had fought Goo off by himself for several minutes.
He tried to argue that Mina and Midnight were also big helps, but reporters had caught him carrying them out of the building. So many assumed that he had saved them somehow. Izuku wished that was true. Because right now, as far as he was concerned, they were in more danger at that very moment than they were in the mall.
The day may have passed uneventfully, but the night was a very different story.
Mina Ashido had never been more frightened in her life.
She had no idea what the horrible thing that had crawled inside her was. Only that it was controlling her every move, speaking every word for her, laughing for her. It was so strange, being a prisoner in your own body. Was this thing in Izuku too? It had come from him. Was Izuku a prisoner in his own body along with her?
Not quite, sweetheart.
Mina would have jumped if she could, at the sudden intrusion in her mind. Instead her body continued to laugh and joke with the other girls as they watched TV in the dorms.
Sorry for not talking to you earlier. I took you over mostly as defense against being found out. So, this copy of me wasn't quite ready for an infection.
Who are you?
You can call me Brain-Jacker. You can thank me for that wonderful date you had with Izuku.
You… you took him over too?!
Not quite, my original self is in there, but I can't take over men. I can piggyback inside them though. Mess 'em up. Scramble their brains and all that. But you really shouldn't worry. I don't like killing. I enjoy other things. Fun things. You'll find out later tonight when Izuku gets back.
I don't understand! What are you? Why are you doing this?!
As I said. My name is Brain-Jacker. I'm a villain that likes to fuck, and make others fuck. I love sex and exploring sex in new and interesting ways. I've pretty much settled on what I enjoy though, so don't worry. I won't make you try a bunch of the really gross stuff. Been there, done that.
The villain's words brought no relief to Mina. Her apprehension and nervousness only grew. What was she going to be made to do when Izuku got back? She was afraid she already knew the answer and she didn't like it one bit. She liked the boy, sure. But she wasn't ready for… all the other stuff! She was a romantic, but she wasn't loose!
Oh honey, that's going to change very soon.
With a sudden jolt, Mina found herself in charge of her body again. Her eyes went wide and she began to stare at her hands, confused and terrified. What was going on? Why had this parasite, Brain-Jacker, why had she given her back control?
Because you're going to do everything I say, anyway. Or I take your body for a joyride off the roof.
Mina began breathing heavily, tears forming at the edges of her eyes.
"Woah, Mina, are you ok?"
Mina turned to Jiro who was lounging on the couch next to Tsu. Both girls looked concerned for her, though they weren't the only ones. Uraraka, Yao-Momo, and Hagakure were staring at her too. Mina opened her mouth but couldn't speak. She swallowed nervously and tried to speak up again, but no words came out.
We need to set up some ground rules, sweetie. No revealing that I'm here. Ok? Or I'll make you do things a lot worse than death. Just remember the internet is forever, and I can do whatever I want with you.
She steadied herself, and wiped her tears. This was horrible. But she would power through it. She wouldn't let this villain win. She needed to keep calm. Though it was easier said than done.
"I'm fine. Fine. I just… I was thinking of a really sad movie is all."
None of her friends bought it, but they didn't pry. Mina caught Yao-Momo and Uraraka sharing a look, and saw Jiro rub her arm nervously. Tsu didn't seem nervous, but her finger was placed on her chin, obviously trying to think about what was really wrong. Mina's heart was pounding fast. She needed to get out of there. She needed to think, or cry. One of the two.
"S-sorry guys, I need to go."
With that the pink teen jumped up and ran to her dorm room to be alone. Jiro, Hagakure, and Tsu all yelled after her, but Ochaco and Momo shared one more look. They knew. They knew what had happened. No one had told them, Brain-Jacker hadn't said anything. But they knew. They'd seen Mina's sudden jolt. They'd seen the mood swing. Not to mention, she'd been alone with Midoriya. It wasn't a difficult conclusion to reach. The real question was what they should do about it.
"Man, I wonder what's up with her. You don't think Midoriya tried anything on their date, do you?" Jiro asked, twirling one of her earphone jacks.
"What?! Don't be ridiculous! Izuku wouldn't do anything like that!" Momo interjected.
"Yeah! Its probably related to the villain attacking! She and Izuku faced him all by themselves! It was a real life or death situation, that can be really scary!" Uraraka agreed with Momo.
No one corrected Uraraka on the fact Midnight had been there too. Tsu nodded, however, agreeing with Ochaco.
"The truth is…I still have nightmares." Tsu whispered.
Jiro's attention was piqued.
"Nightmares, Tsu? About what?"
Tsuyu bowed her head, and held herself tightly.
"I still have nightmares from the USJ incident. I still see Shigaraki's hand coming towards me… and sometimes Midoriya and Mr. Aizawa can't stop him. Sometimes… I just turn to dust. Coming close to death, it changes you. I'm better now, but right afterward… I couldn't sleep very well for about a week. I had to go see Mr. Hound Dog for counseling."
The girls were silent for a few seconds, each quite shocked to hear that.
"I… I had no idea, Tsuyu. I'm sorry." Jiro said.
"You poor thing!" Hagakure jumped over to her friend and gave her a big hug, trying to comfort the poor girl.
Ochaco and Momo, meanwhile, stood up with determined faces.
"We're going to go talk to Ashido!" Ochaco said, "You guys stay here for now. We don't want to swamp her."
"Yeah, leave this to us." Momo said, her fist clenched in determination.
However, before the two dashed off to comfort Mina, they were stopped by someone coughing to get their attention.
That someone being Mr. Aizawa.
"Well, you two look busy so I'll make this short."
The boys noticed their teacher too and looked up from the table, Iida speaking what everyone was thinking.
"Mr. Aizawa, what are you doing here?"
Their teacher gave a melancholy sigh as he shuffled forward.
"I have some news for Tokoyami, Kirishima, Uraraka, and Asui. Tokoyami, you've been requested personally by Hawks for the work study. As for you other three… Kirishima, Amajiki has requested you speak to him. Uraraka, Asui… Nejire has requested your presence."
"Woah, seriously?! One of the big three wants to talk to me?!" Kirishima was quite shocked to find he had been singled out.
Meanwhile, Ojiro and Kaminari were congratulating Tokoyami.
"That's so cool, man! He's the number 3 hero! And he personally requested you! Bad ass man!" Kaminari said exuberantly.
"Yeah, Tokoyami, that's amazing. I'm jealous!" Ojiro responded in a much tamer tone.
"Wait, Nejire wants Ochaco and me? Why?" Asui questioned from under Hagakure, who was still hugging her.
"I assume she wants to help you with your work studies. You must have caught her interest somehow. Now one last thing before I go… where's Midoriya?"
Everyone in the dorm looked about, seemingly realizing for the first time that he wasn't there.
"Hmmm. Never mind then. Guess I'll have to find him myself. The rest of you, don't stay up too late."
As Mr. Aizawa left, Momo and Ochaco took another look at each other and nodded their heads once. It was time to help Mina. Because they were the only ones that really knew what she was going through.
