The young, blonde woman looked up at UA High School with a smile as she pulled out her phone and started texting.

I'm here, Uncle Might!

Putting her phone away, she waited patiently for the retired hero to arrive. She didn't have to wait for very long as she spied the tall, lanky man quickly making his way towards the school gate.

"M-Melissa! Why didn't you call when you arrived in Japan? I would have come to pick you up at the airport!" stated All Might as he tried to regain his breath.

She could only let out a giggle. "I know, Uncle Might, but I wanted to surprise you and everyone else!"

The retired hero merely shook his head in amusement. "Well what's done is done. Are you ready for a tour of UA?"

"Not yet. I was hoping to see Izuku first," replied Melissa, a smile coming to her face as she thought of her friend.

Returning the smile, All Might nodded. "Very well then. Follow me."

Turning around, All Might headed towards the Class 1-A dorms with Melissa close behind.

-:-

"Okay, Eri. Which of these items is on the card?"

Confused red eyes looked at the three objects (an apple, an orange, and a banana) before her and then looked at the card in her Papa's hand that said "apple" in English.

Yes, Izuku was currently trying to teach Eri how to speak and read English; something Kyouka agreed would come in handy in the future.

"Come on, sweetie. I know you can do it," said Kyouka, encouraging the little one sitting on her lap.

Looking back at the card and then the fruits, Eri smiled as she reached for one of them.

"Apple!" squeaked the child as she held up her favorite treat for all to see.

One could not describe how proud Izuku and Kyouka were in that moment.

As the shy couple congratulated their daughter, some of the other members of Class 1-A watched on.

"So why are they doing this again?" questioned Kaminari, trying to be quiet enough so Kyouka couldn't hear him. "Why not just have Mic-sensei teach Eri? He is an English teacher after all."

"He is also a Pro Hero and is currently out on patrol now that the school day is done," stated Tokoyami, crossing his arms.

"Okay…but what about that Pony girl from Class 1-B? English is her native language," said the electric boy.

"They would have," started Momo, a worried look on her face. "But they knew if they did then there would be a high chance of Monoma harassing her for helping anyone from the "evil" Class 1-A."

"Besides, I think it's cute that Deku-kun and Kyouka want to be the ones to teach Eri-chan!" chirped a giddy Ochaco.

"Plus, Midoriya and Jirou are the top two students in our English class," added Shouto. "It only makes sense that they would want to teach Eri."

They watched as the shy couple continued with the next flash card for Eri's lesson. There was then a knock at the door, to which Ochaco stood up to go answer it. When she opened the door she was greeted by All Might and…

"Melissa?!" exclaimed Ochaco, shocked and happy to see the American girl. This also caught the others' attention. "What are you doing here?!"

The blonde gave off a smile. "I came to visit Uncle Might, Izuku, and everyone else. I hope that's okay."

"O-Of course that's okay!" said Izuku as he made his way over. "B-But why didn't you call beforehand?"

"Like I told Uncle Might, I wanted it to be a surprise," replied Melissa with a giggle as she and All Might entered the dorm.

"Oh, it was definitely a surprise," stated Kyouka with a slight laugh as she and the others came over to greet the older girl.

Another giggle came from Melissa before something caught her eye. A little girl was hiding behind Kyouka's legs, looking at her with trepidation. Before she could question whom the child was, the child looked over towards Izuku.

"P-Papa? Wh-Who is this lady?"

Melissa had a blank look on her face. Did she hear the child right?

"This is Melissa Shield, Eri, and she's a friend of mine," replied the greenie with a reassuring smile. "Why don't you say hello?"

Stepping out from her hiding spot, Eri gave a small bow. "H-Hello. My name is Eri."

"H-Hello, Eri," replied Melissa, still trying to comprehend what she heard. She then turned to Izuku. "Wh-Why did she call you "Papa"?"

The fluffy-haired boy rubbed the back of his head. "W-Well, that's because she's my daughter. I adopted her."

It took a moment for the information to set in and when it did, Melissa's reaction was unexpected to the UA students.

Teary-eyed, she started to tremble. "I'm an auntie now?"

'Wait, what?' thought the students, minus Izuku and Kyouka.

With speed that they didn't think was possible from the Quirkless girl, Melissa scooped up the child and held her close.

"Ah, you're just so cute!" exclaimed Melissa as she nuzzled Eri, causing the little girl to giggle. She then cast a glare towards All Might, making him flinch. "Uncle Might! Why didn't you tell me that there was a new baby in the family?!"

The retired hero gave off a nervous cough. "It never came up?"

Rolling her eyes at the answer, Melissa turned back to Eri and smiled. "No matter. I know now and as your auntie I'm going to spoil you rotten!"

As Melissa continued to dote on her newfound niece, the UA students were discussing about what the hell just happened.

"Hold up, why is she claiming herself as the unicorn's aunt?" questioned a confused Kaminari. "That doesn't make any sense!"

"Of course it makes sense, Jamming Yay," replied Kyouka, rolling her eyes. "Melissa has always seen All Might as her uncle and we all know All Might and Izuku-kun have a father son relationship…"

"I still standby the theory that Midoriya is All Might's secret lovechild," stated Shouto, only to let out a soft grunt when Momo gave him a light elbow jab to the ribs.

"Putting those two facts together, it's not surprising that Izuku-kun and Melissa would have a sibling-like relationship," continued Kyouka, ignoring Shouto's remark. She then stepped forward and took Eri from Melissa's arms. "That being said though, please refrain from spoiling Eri. Bad enough Yaomomo keeps trying to."

While Momo pouted at the dig, Melissa was confused as to why Kyouka would care about whether or not she spoiled Eri. She was about to ask when Eri asked a question of her own.

"Mama, what does spoil mean?" asked Eri, looking up at Kyouka.

"It's not a good thing, sweetie," replied Kyouka, holding her daughter close. "Someone who is spoiled is the exact opposite of your Papa, who worked hard to get where he is and wasn't just handed everything to him."

"I want to be like Papa when I grow up then!"

Kyouka smiled as she hugged her little one. "I know you will, sweetie."

Melissa could only stare at Kyouka and Eri before she turned to the blushing greenie with a narrowed look.

"Explain. Now!"

Izuku's blush became a bit more prominent. "K-Kyouka happens to be m-my g-girlfriend and Eri's m-mom."

"…And you didn't tell me any of this at any point why?"

"…It never came up?" replied Izuku nervously, using the same excuse as All Might.

The blonde gave her "little brother" an admonishing glare.

Not wanting his boy to get the third degree, All Might decided to step in. "Ah, Melissa! How about a tour of UA?"

Of course Melissa could see right through the diversion. "Sure, but this isn't over, Izuku!"

The greenie could only let out a groan as Kyouka gave him a reassuring pat on the arm.

-:-

The tour went well as Izuku, Kyouka, and All Might showed Melissa around the campus. The American girl had met plenty of the UA teachers and staff and Melissa definitely had a few opinions on them.

"Mr. Mic seemed really nice. At least much nicer than Mr. Aizawa anyway," stated the blonde with a giggle.

"Yeah, but there are times when Mic-sensei can be too much," replied Kyouka with a sigh, before muttering about there were too many annoying and/or embarrassing blonds in her life as she thought of not only her mentor but also her father and a certain electric idiot.

"I do have to wonder about Miss Midnight though," continued Melissa with a frown. She then glanced down at Eri, who was holding Kyouka's hand. "She doesn't act like that around Eri, does she?"

Izuku answered this one. "Midnight-sensei, despite how she portrays herself, actually knows when to stop and be serious. Much more respectable as a hero than say Mt. Lady or Uwabami."

The little one looked up at her Papa in confusion. "Oobammy?"

"Uwabami, sweetie," replied Kyouka with a slight laugh, getting Eri's attention. "She was very mean to your Momo-obachan."

Eri's eyes widened slightly before she frowned. "I don't like Oobammy."

"Neither does your Momo-obachan."

All Might had also frowned as he listened in on the conversation. What did Uwabami do to young Yaoyorozu? He would have to talk with Nezu and Aizawa and see if they knew anything about this. In the meantime, they had arrived to their next stop on the tour.

Entering the Development Studio, the small tour group was greeted by the eccentric inventor of Class 1-H.

"Midoriya! Are you here to help test out more of my babies?!" exclaimed Hatsume excitedly as she pounced the fluffy boy.

"H-Hatsume!" squeaked out Izuku, blushing brightly as she pressed against him.

Luckily, Izuku was saved when an earphone jack snaked its way into Hatsume's ear and pumped out a few sound waves.

"Gah!" cried out Hatsume as she let go of Izuku and dropped to the floor.

"You were warned last time, Hatsume," ground out Kyouka, glaring at the twitching pink-haired inventor. Eri was currently hiding behind her Mama's legs, afraid of what else this strange lady could do.

Melissa could only stare wide-eyed, wondering what she just witnessed with this new girl. A nearby sigh caught her attention and she turned to find a very short man (who looked to be the exact same height as Kyouka) in an excavator-like helmet making his way over to them.

"Seriously, Hatsume," said the man with another sigh. "What did you do this time?"

"She still hasn't learned about personal space," answered Kyouka as she continued to glare at Hatsume, who was picking herself off the floor.

The man could only shake his head before turning to the retired hero. "Hey, All Might. So brings you to my neck of the woods?"

"Nothing much, Power Loader. Just showing my niece around UA," stated All Might as he introduced Melissa to the Excavation Hero. "Her father was the one who made all my previous gear and costumes and she plans on becoming an inventor as well."

"Oh yeah?" questioned Power Loader turning to Melissa and giving her a friendly grin. "Well you've definitely come to the right place! Feel free to look around. Maybe you'll be able to find some inspiration."

"Ah, thank you very much, Mr. Power Loader!" replied Melissa, returning the grin.

Hearing this, Hatsume frowned as she looked back and forth between Midoriya and the new girl before turning to Midoriya with a pout.

"Midoriya! What's the big idea?! I thought I was the one who would be making your support gear?!"

This caused Izuku to stammer out incoherent sentences while Kyouka could only roll her eyes. Luckily, Melissa took the opportunity to intervene.

"Oh! You must be the one Izuku is always talking about!"

The pink-haired inventor blinked in confusion, turning to the older blonde. "Huh?"

Melissa let out a giggle as she explained. "Izuku speaks highly of your work. He's said he wouldn't have been able to beat half of the villains he's faced if it weren't for the support gear you made for him."

A grin of pride spread across Hatsume's face. "That's because my babies are the best!"

As the two science girls conversed, with Hatsume showing off some of her inventions to Melissa and a curious Eri, Kyouka turned to her boyfriend with her arms crossed.

"So, you've told Melissa about Hatsume?" she questioned with a raised eyebrow.

Blushing slightly, he answered. "W-Well, I figured since Melissa-nee was also in Support that she would be interested to know about Hatsume. Y-You have to admit that she can't be beat when it comes to support gear."

"…Yeah, you're right about that," replied Kyouka with a sigh as she leaned into her man. "Those wrist mounted amplifiers she made for me have been very helpful."

A chuckle escaped Izuku as he wrapped an arm around Kyouka's shoulders and held her close. "See? I know Hatsume can be a bit…eccentric, but it just goes to show how passionate she is about inventing stuff. You and I should both know what it means to be passionate about something."

Kyouka could only smile at that. He was right; with her passion for music and his passion for Quirk analysis, they did know. That's probably why they were some of the VERY few people who could tolerate Hatsume more than others could. She was pretty sure Iida and Ochaco still didn't care for Hatsume that much.

That of course didn't mean she wouldn't pump a few sound waves into the inventor's ear if she kept invading personal spaces in the future.

-:-

The sun was now setting and the small group had returned to the dorms, which was where Melissa would be staying for her duration here in Japan.

"Are you sure, Melissa? You're more than welcome to stay in my guest room," offered All Might as he looked at his niece.

"I appreciate the offer, Uncle Might, but I was hoping to hang out with Izuku and the others and maybe get to know Eri a little more. I-If that's alright with you," replied Melissa, not wanting to upset her uncle.

But her worries were for naught as All Might just smiled and patted her on the head. "Of course it's alright, my dear. I'm just glad that you're making friends and I know your father would feel the same."

"Thank you, Uncle Might!" she replied with a beaming smile.

The retired hero then turned to Kyouka. "Young Jirou, would be willing to show Melissa to one of the spare rooms?"

"Sure thing, All Might," said the purplette. She then looked down at her daughter. "Come on, Eri. Let's show your Melissa-obachan where she'll be sleeping."

"Okay!" chirped the beaming child as she and her mother led Melissa towards the elevator.

Once they were gone, All Might let out a sigh. "I can only imagine David's reaction once Melissa tells him about Eri."

Izuku turned to his mentor and father figure. "His reaction? What about my mom's? You know she's wanted to meet Melissa since you told her about her. She's not going to be happy when she finds out that Melissa's here and no one told her."

All Might grimaced at that. Inko would definitely be upset that she might miss out on meeting Melissa.

"…You'll have to excuse me, my boy. I need to make a quick phone call," stated the tall blond as he turned and left the dorms.

Izuku could only sigh as he preparations for the high possibility of his mother visiting tomorrow.

FIN

-:-

And thus Melissa has met the little one. Now imagine a completion between Melissa and Momo for position of favorite auntie.

There was originally going to be a scene where Melissa meets the Big 3 (as well as Inko), but I figured I could use that for its own one-shot. That's pretty much why the ending is a little open-ended, so there can be sequel/part two where Melissa continues her days at UA.
