**This oneshot has the reader with Multiple Personality Disorder (MPD) / Disassociative Identity Disorder (DID) . I am aware that the symptoms and presentation of the reader in this oneshot may not line up with how you (or someone you know) experiences MPD/DID so just bear this in mind as you read. MPD/DID is a very complex disorder and every individual presents differently.
This reader has one alter and is unaware that they have this headmate at first (I have named the alter and given a backstory, just for ease of writing) and I have written their switch to be more overt so that it is easier to tell when the alter has come out. Most headmates/alters switch without any to little outward sign- only a small percentage have overt switches.
Although it is unadvisable to diagnose someone with MPD/DID (such as Aizawa suspecting this to be the case) I would like to think that heroes in the BNHA world would have to have some level of counseling training as part of their job and so he [Aizawa] would be able to make an educated decisions within his scope of knowledge.
If you do have MPD/DID and have decided to read this oneshot then please be aware that this could cause a disassociative episode; one of your alters or headmates to switch in; or some other self protective maladaptive strategy to occur – so please read at your own risk.
If you are unsure of you have MPD, DID or any other disassociative personality disorder- but resonate with the things mentioned in this story- please seek the medical attention as soon as possible.
It had been ever since the accident, that he had noticed a marked change in your personality at times. Some of the other class members had noticed too but no one had said anything, they just thought you were really hyped whenever you changed into your hero costume.
He, your teacher- Aizawa, kept an eye on you though. He had an idea as to what was going on but he didn’t want to expose you in front of the class.
Naturally, you had attended counseling after the incident on patrol… or so Aizawa had thought. But your alter had already materialized and come out by then, and in his state you didn’t need counseling- you didn’t even remember the event so why go to counseling if nothing was wrong, right?
In class one afternoon, Aizawa called everyone’s attention to himself.
“We’re doing training this afternoon,” he said, his bored expression glossing over everyone there, but especially you, “in ground Beta, the building section.”
You stiffened when you heard him mention buildings… that’s where the incident had taken place.
As Aizawa continued to talk, your eyes fluttered closed as your alter started to fight for control of your body.
Aizawa saw and kept talking.
“We will be practicing saving people from jumping off buildings.”
Your body twitched and your altered state awoke, sitting you up straighter and assuming a power pose with legs spread open and a cool smirk on your face.
“Savin’s what I do,” your alter said loudly, thumbing your nose before running a hand through your hair to ruffle it a bit.
“They just switched,” Aizawa thought as he watched your whole demeanor change.
“That’s the idea, Y/N!” Kirishima said happily, feeling the manly vibes you were throwing out there.
You grinned back at him and threw him the backwards peace sign before looking back to Aizawa.
“Pay attention,” Aizawa said sharply, “go and change now and I will meet you on site.”
All students got up and started heading out to the change rooms and you walked to your locker to get your clothes and then walked off to get changed.
“Y/N get really into character don’t they?” Uraraka commented to Momo as they walked to the change room together to get dressed into their hero gear.
“They do,” Momo replied, “but it’s good to get into hero character when you go out to save people.”
“Yeah,” Uraraka replied, “it’s very plus ultra.”
They entered the room, finished up changing, then made their way out to the beta area.
“You’re always so ready to go!” Kirishima commented to your alter as they walked side by side out to ground Beta.
“It’s what a hero does,” your alter replied with a large grin.
“So you’re ok after… uh… what happened before?” Kaminari questioned you from the other side.
“Of course,” you snorted.
“Guys, leave Y/N alone you’re crowding them,” Jirou said from beside Kirishima, trying to get closer to you.
You all headed out onto the training grounds to where Aizawa was waiting for you all.
Y/N,” he called to you.
You looked at him.
“You’re up first,” he said calmly, watching you.
You didn’t flinch at all.
“I’m going to be up on the roof,” he said, turning and heading inside the building on site.
“Good luck, Y/N,” Kiri said, patting you on the back.
“Piece of cake,” you replied confidently as you strode towards the doors and started heading up inside the building.
You got to the top level and opened the door, the first thing you saw, was Aizawa standing on the edge of the building.
He was facing away from you, over the edge but he had his head turned a little so the he could observe your movements and reaction from the corner of his eye.
“A normal response would be to balk a little… this is a traumatic reawakening but Y/N seems completely unfazed.” His eyes watched you keenly, expecting some hesitancy but you walked straight out and talked Aizawa down from the edge very effectively and calmly.
He allowed you to get him back from the edge and followed your orders, then went back down to the rest of the group there.
Going through the rest of your classmates and their responses to him pretending he was going to jump from the roof , he could tell that it wasn’t truly you who had done that training exercise just then, so once everyone had finished the test, he let you all go back to the change rooms to change.
As you were getting out of your hero outfit you suddenly switched back and you stared down at yourself in confusion.
“What’s??… why am I getting changed?” You looked up around the empty room then back down again, “am I getting out of this or into this?”
Hesitantly you took it off and got back into your school uniform then walked back to class.
You had a headache and felt a little dizzy but these feelings had been occurring for a while now so you didn’t think much of it- although they had been happening more often now.
Entering the classroom, you sat down at your desk quietly and avoided eye contact with your classmates.
“Y/N! You were so amazing out there!” Kiri said to you as he walked over to fist bump you.
“I… I was?”
“Yeah! So manly!” Kiri gushed with pride.
“Oh… yeah,” you replied with a forced smile, “cool.”
Kiri was about to say something else but Aizawa walked in and demanded everyone sit down- which saved you from having to say anything else, then he continued with class.
“Y/N,” Aizawa said, calling on you, “please give us a brief overview of your actions today and what made you take that approach.”
“Ah shit,” you screeched internally, “I don’t remember anything, did we do a training exercise? Why don’t I remember??”
Aizawa saw the terror on your face and turned on Bakugou instead.
“Bakugou,” he said, “you need to work on your approach. You cannot threaten someone, who is about to commit suicide, with the promise of blasting them off the side of the building if they don’t hop down.”
“It worked, didn’t it?” Bakugou scowled with a grin.
At hearing the word ‘suicide’ you felt your body start to tear in two as you were pushed to the side and someone else took over and started talking on your behalf.
Your alter talked to Aizawa, explaining everything that they had done and your brain felt fuzzy.
This had been happening a lot lately and you looked at your watch to try and keep track of time. How long was this going to last? How much time had passed?
Slowly, that feeling faded, and you felt your body and mind connect in its true form again and you let your head fall into your hands.
“What’s happening to me?”
After class ended Aizawa asked you to stay back.
You did, and when everyone had left, you approached his desk.
“Y/N… may I ask a few questions about your personal life?” he asked in a low calming voice.
“Have you suffered any traumatic experience as a child?” he asked pointedly.
“My… Mum…” your eyes started to flutter a little and then you fell silent.
Aizawa placed a hand on your shoulder gently and you looked up at him.
“I’m going to make a call to a highly trained professional friend of mine,” he said softly.
“I dunno why you’re calling your friend,” you said, your speech changing slightly.
Aizawa nodded. “I have a feeling I know what’s happening and I’m here to help you.”
Aizawa and your alter didn’t see eye to eye because, as your protective alter, he didn’t see any need for you to be ‘protected’, ‘saved’ or ‘helped’ because he was doing that job just fine.
But finally, over the course of a few months, you got the treatment you needed and you (as the host) became aware of your alter- which you came to know his name as Bloke. Bloke split off from you when you were 3 years old when your mother committed suicide by jumping from your apartment balcony.
You had seen the whole thing- but Bloke had been there to protect you from mentally hurting too much, and since then had always stepped in whenever he felt like you were under stress. Bloke was great at hero work and once you became aware of him, you and he would work together as best you could, saving all kinds of people.
Aizawa kept an eye on you throughout your time at UA, and made sure you were ok during your treatment as well. He became an integral part of your life and you looked up to him like a father figure. Once you had graduated your studies, you started your own agency, working alongside him.
He really looked out for you, and Bloke grew to like him too. You felt comfortable around him and Bloke often came out to speak with Aizawa when you two were alone.
“Have you got work tonight?” Aizawa asked one afternoon as you entered his office.
You eyelids fluttered and you took a deep breath in.
“Sure do! Savin’ is what I do,” Bloke replied with a grin.
“Good,” Aizawa replied with a small smile, “go and save as many as you can.”
