AN: I used snippets of canon information from the anime, season 1 and 2, to justify this. No spoilers for anime season 3 or beyond, although I read too far into everything All for One says in the manga and it might be unintentionally referenced/taken out of proportion. I totally think this could be possible. Wishful thinking that Deku's dad is a villain. Anyway, enjoy! Disclaimer: I do not own My Hero Academia or any of the characters.

"In order to put minds of our students' parents at ease after the villain's appearance at the mall yesterday, we will be holding an open house of sorts in the form of bring your parents to school day." Aizawa began in a bored, yet stern tone. "As advised by principal Nedzu this will take place this upcoming Saturday, two days before we leave for our new summer break location."

That's only three days away, Izuku pondered. This must have been a really split second decision.

"Your parents will be allowed on campus from noon until four o'clock. During this time you will be responsible of escorting them around campus as well as making sure they are off school grounds by four. All members of U.A. faculty will be present to talk to your parents, or legal guardians, so if they have any questions for us after your first year here it will be a good opportunity to get them answered. Before you leave today I would like all of you to write down on this sheet the names of those who might attend so we are able to properly implement our security measures come Saturday. Make sure to let them know visitors must have some form of identification on them while on campus, such as an ID. While you should be with your parents at all times this will leave them the freedom of coming and going as needed. If you do not have anyone that wishes to attend please let me know that as well. That is all."

With that he handed the paper he was holding to Aoyama, and then wordlessly slipped into his telltale yellow sleeping bag. Barely a few seconds had passed before he was lying on the ground with his eyes closed, completely ignoring the excited chattering of his students.

"This is so exciting!" Mina squealed from where she sat behind a naturally sparkling Aoyama. Once he was done writing his parents' names down, she took the sheet with gusto. "My parents have been dying to get a tour of campus and meet the teachers since the day I got accepted. Oh, and they'll get to meet all of you guys too! I talk about you a lot, but now they'll get to put your names with faces."

"You talk about all of us?" Kaminari asked, flattered. Tsuyu signed the sheet next. "I really only talk to my parents about our foundational hero training class."

"Same," Sero added.

Mina frowned, her lower lip pulling forward into a pout as Iida quickly filled out the form before handing it back to a smiling Uraraka. "Really? And to think you two were part of the 'Bakusquad'. I bet Kirishima talks about his classmates."

Bakusquad? Izuku thought, confused for a moment. Oh, she must mean Kacchan, Kirishima, Sero, Kiminari, and herself.

The red-haired hero in training grinned broadly. "Of course I do! I tell them about nearly everything going on in my life. We're super close. Honestly, I can't wait to meet everyone else's parents. It'll be so cool to ask Bakugo's folks for pictures of him when he wasn't so angry."

Sato signed his parents' names next, handing it off to Koda who then handed it off to Kirishima only after Bakugo was done yelling at him.

"What did you say, shitty-hair? I'm not always angry. I just get annoyed when I'm surrounded by idiots or extras, which is almost always!"

From where Izuku sat behind his childhood friend, waiting patiently as the form he needed to fill out was passed to Kaminari, Ojiro, Shoji, Jiro, Sero and Tokoyami before settling on a quietly contemplating Todoroki's desk, he laughed. "Kirishima-kun, I'm not sure they carry around pictures of four year-old Kacchan anymore. His mom and dad will probably try and tell you some funny stories about him from when he was little though. As long as they are the ones to tell you Kacchan won't come after me for embarrassing him."

"Shut the hell up, Deku! Don't give these idiots stupid ideas! You're the one that needs to worry about your mom embarrassing you with all of the baby pictures she has in that purse of hers."

"Really?" Hagakure and Mina yelled excitedly.

"I bet baby Deku was so cute," Uraraka said thoughtfully.

To her surprise, Todoroki found himself humming in agreement from where he gazed intently at the paper on his desk. "I wonder if Aizawa-sensei can get me the proper paperwork for my mother to visit. There's no way I'm putting my father's name down. Not that he'd need my permission to visit these grounds anyway."

"I'm sure Aizawa-sensei will be able to figure something out," Izuku comforted. "Put your mother's name down anyway. It won't hurt."

Nodding at his optimism, Todoroki wrote his mother's name before finally giving the sheet to Yaoyorozu. She finished with it in a few seconds before passing it to Mineta.

"What about your father, Midoriya?"

"Huh?" The fire and ice user's question caught him off guard.

"Your father," he repeated, "will he be attending too? In the past year here I've only ever heard you mention your mother."

Izuku's smile slipped off his face faster than anyone had ever seen. "I highly doubt he'll attend, but I guess I'll put him on the list anyway. It'd be a pretty crazy first meeting if he did show up."

"What do you mean by first meeting?" Mineta asked as he gave his friend the form.

"Ah, well," Izuku sputtered as he swiftly wrote both Inko and Hisashi Midoriya onto the guest list, "I've actually never actually met my father? He didn't die or anything. It's just ever since I was born he's been away on business overseas, or at least that's what my mom has been telling me for fifteen years. We get checks in the mail to support us, so we know he's alive, but since I've never even seen or talked to him it sort of feels like he doesn't exist."

"Does your mother keep in contact with him?" Iida found himself inquiring. Bakugo begrudgingly filled out the form with before Hagakure finished it off and left it on Aizawa's desk for when he awoke.

"Yeah. She says he sends letters from time to time, but she misplaces them almost as soon as she gets them somehow. I never get a chance to read them myself. We don't have any pictures of him in the house either, so I don't even know what he looks like."

Yaoyorozu seemed confused at his statements. "Not even one picture? That seems a bit odd. What exactly is his profession again?"

"All Deku knows about his crappy old man is his name, that he breathes fire, and that he's a lame-ass business man who cares more about his job than his family." Bakugo cut off in a huff.

Izuku sighed. "Kacchan, I'm sure he has his reasons. He's still my father even if he's far away. Although now that you mention it Yaoyorozu-kun, I could ask my mother what he looks like. I hadn't really thought to ask when I was younger because I assumed he would come home to visit us at some point after my birth, but I guess he's got a lot going on."

His classmates noted the tinge of sadness as he spoke, obviously holding some bitterness against his father despite his forgiving and kind nature. Noticing this, Mineta helpfully changed topics as everyone started to get up and leave.

"Hey, Tsuyu," the grape-headed said obnoxiously, "is one of your parents a frog? If so, how does that work?"

"They both have amphibian-related quirks, ribbit. You know, Mineta, you'd better be on your best behavior during the open house. I'm pretty sure Jiro has been waiting for the chance to tell someone like your parents about your perverted thoughts and behavior."

"She would not!"

The girl in question stared at the short boy emotionlessly. "I totally would, so you'd better start acting decent."

Izuku smiled as his classmates slowly began making their way out of the classroom. Aoyama gushed to a silent Koda about his dazzling parents while Ojiro, Shoji, and Tokoyami talked about their own families. Sato mentioned to Hagakure how he was planning on bringing in a bunch of sweets for the event, to which the invisible girl was literally jumping up and down with joy. Even Bakugo was more or less in a good mood, not bothering to shove Kirishima, Sero, Mina, or Kaminari away from him as they made their way out of the room as a group. Todoroki and Yaoyorozu spoke to each other as Tsuyu, Jiro, and Mineta walked a few paces behind them. The One for All user smiled as he watched his friends and classmates appearing so content, nearly overlooking the fact Uraraka and Iida were patiently waiting for him by the door.

"Spaced out there for a second, huh?" Uraraka guessed as he quickly gathered up his things and bounded over to them.

Izuku rubbed the back of his neck sheepishly. "Maybe. I was just thinking how amazed my mom is going to be when she visits. I talk about literally everyone in class to her, so when she gets to meet all of you I'm sure she's bound to cry from happiness. She's really wanted to meet you guys for a while now."

Iida raised an eyebrow. "That seems like a strong reaction. Do you really talk us up that much, or is it because she's just excited to meet your friends?"

"More of the second thing. I've only ever mentioned Kacchan at home up until high school. He was my only friend until we were four or five, then, well, I sort of stopped talking about anyone at all. My mom's just happy I have so many people in my life to talk about now."

"Why didn't you have anybody else to talk about in elementary or middle school? Surely you had friends other than Bakugo even before your guy's falling out."

Izuku winced. "Um, not really? After I was diagnosed quirkless and Kacchan deemed me useless nobody wanted anything to do with me. If they hung out with me they would just get picked on or worse, so I was avoided. You two were the first friends I made since I was four."

For a moment the duo was silent, and Izuku worried that he'd revealed too much about his past. He didn't want to make them feel sad or anything. Sure some parts of his childhood sucked. Some moments were downright horrible. Still, he felt like it could have been much worse all things considered. He really didn't want them to feel sorry for him.

"I'll make sure she gets to meet Iida-kun and I first then," Uraraka said determinedly as they made their way down the hall to leave school. "We'll make sure she knows we're by your side at all times so she doesn't have to worry about you! After how you told us she reacted to the Shigaraki thing I'm sure it would help ease her mind to know we'll have your back."

"I agree," Iida said with a smile. "Not only am I the class rep, but I care about you as a dear friend too, Midoriya. Your mother can rest soundly knowing we'll keep an eye on you. A friend's happiness and safety is always top priority!"

Izuku and Uraraka found themselves giggling at how over the top Iida got with his charisma. With the silly poses he struck it would be hard to tell at first glance that he'd come out of a private school just a year ago.

"Thanks guys. It means a lot."

The smile Izuku shown could easily thaw even the coldest of hearts. Uraraka and Iida smiled in return, the trio chatting easily as they made their way home.

That night at dinner, Izuku's curiosity got the better of him.

"Hey, mom?" He mentioned offhandedly in between bites of katsudon. "Can I ask you a question about dad?"

She seemed a bit surprised at the topic change, but nodded nonetheless. "Of course, sweetie."

"Do you remember what he looks like? I just realized we don't have any pictures of him around the house. Is that because you only have a few and are keeping them stored away safely, or did you not have any to begin with?"

Inko frowned. "He never took pictures, now that you mention it. He also left before you were born, so all of the pictures hanging up are of the two of us, of Mitsuki and I from high school, or Katsuki and you from preschool. As for what he looks like, the last I saw him was roughly sixteen years ago. He probably looks vastly different nowadays since then."

"I know, but what did he look like when you married him? I take after you in terms of hair and eye color. Can you tell me if I have any of his features?"

Izuku waited patiently for his mother to respond, eating a couple bites of katsudon as he waited. When nearly two minutes passed without his mother responding he became worried.

"Mom?"

Inko didn't respond verbally, her forehead scrunching up as she seemed to pull herself deeper in thought. She broke into a sweat after nearly a minute of her beginning to mumble nonsense to herself. Izuku got up to stand at her side, bending down slightly so that his head was closer to her own.

"Mom, are you okay? What are you saying? Mom!"

"I can't remember," she whispered hoarsely. "What kind of wife can't remember what her husband looks like? I can't even recall the details of our marriage. We have a wedding certificate somewhere, I know, but all of the letters he sent are missing. Would I really misplace so many letters? Izuku, sweetie, I can't remember anything about Hisashi. Why? Why can't I remember your father?"

The more she spoke the more upset she became. As she grew more frantic her face paled significantly, and all of a sudden she was screwing her eyes shut and grabbing her head in pain.

"I don't feel good. My head is suddenly pounding like crazy. I'm going to lie down for a bit, okay? Don't worry about me; I think a little nap will help. I'll try to remember something once I'm feeling better, alright?"

"It's fine, mom. Really. I'll take care of putting the food away and cleaning up. Just take care of yourself," he instructed, his voice laced with concern.

She smiled at him softly. "Thank you, sweetie. You're always my little hero."

With that she made her way out of the kitchen and towards her room to rest, leaving Izuku to lose himself in his thoughts. Something was definitely fishy.

After putting the leftovers in the fridge and doing the dishes, Izuku picked up his phone and dialed All Might's number. Within three rings the number one hero picked up. Izuku immediately felt a little shy.

"Midoriya, my boy!" He greeted happily, making Izuku flush. "What seems to be the problem? It's a little late at night for you to be calling."

"Oh, um, I just had a question and a favor to ask if it's no trouble. If you're busy I understand and I'm prepared to wait or ask someone else I know it's sort of late in the evening and you probably have a life of your own and don't want to waste your time answering my questions when you might be in the middle of dinner and I hope I'm not interrupting anything I'd feel so bad if I—"

"Calm down, kid! Jeez, you're going to talk my ear off. I'm not busy at the moment and would be happy to answer your question. As for the favor, I'll see if it's possible."

Izuku breathed a sigh of relief. "Okay, All Might. Thank you. Um, the question I was going to ask was about quirks. I know there are all types of quirks, but have you heard of one that can erase or alter memories?"

For a moment the line was quiet. "I know they exist," All Might finally responded after a breath. "Short and long term memory erasers, alterers, and blockers have been seldom recorded since quirks first arose, yet they have been recorded. What brought you to ask me this question though? Did something happen?"

"Oh, well, it sort of has to do with my mom. I asked her about my father today, whom I've never met because he's been away on business overseas since before I was born, and Yaoyorozu brought up how weird it was that I didn't have any pictures of my father in the house and had never met him. The fact my mom kept losing the letters he's apparently sent is also suspicious. Anyway, when I asked her what he looked like today she became ill and her head started hurting. She said she can't remember anything having to do with my father. We know his name and quirk, but that's it. It made me wonder if maybe someone altered or erased her memories of him. Do you think that's possible?"

"Probably. What do you know about your father, my boy?"

Izuku told him what he knew, mentioning as it came to him the fact that their family doctor had his mother's family history records but nothing on his father or his father's relatives.

"If I text you the account number my father sends us money through as well as his name, do you think your investigator friend can tell me anything about him? Or at least let me know if he knows anyone that would be able to tell if my mother's memories have been altered? I'm sorry if that is too much to ask, but I'm worried about my mom. I also think something weird is going on with my father. I tried searching his name from my phone on the train ride back, but nothing came up."

"I understand and agree that your suspicious is warranted." All Might assured. "How about you text me the information and I'll forward it to Tsukauchi. We're good friends, so I don't think he'll mind this favor. He'll most likely get back to me tomorrow or the next day and I'll call you when I have something to tell you. Is that okay with you?"

"Of course! Thank you so much, All Might."

A laugh came from the other line. "It's no trouble at all, my boy. Anything to help my successor and student out. I hope your mother gets to feeling better soon, by the way. She's a sweet woman and I hate to know she's feeling anything less than well."

"Thank you," Izuku said again. "I guess I'll let you go then. Have a nice rest of your night."

"You do the same, Young Midoriya. Talk to you tomorrow."

"Uh-huh. Bye."

Izuku hung up, mind reeling despite being happy for All Might's help. What would Tsukauchi find tomorrow?
