It was family day today! Everyone's family was able to come to UA to spend some time with their child at the school campus. And it was even more exciting for the 3rd years that were graduating soon. It was only a short time before the 3rd years would start their own careers including the four honorary aunt and uncles of the principal's son.

Hizashi's parents were chatting with Nemuri's parents while Tensei's family were off to the side with Tenya. Unfortunately, Aizawa's parents couldn't really make it because of their work, but his mother informed him to take lots of pictures for her.

Hizashi was busy with Tensei as they were checking up on Tenya who was excited to show Izuku his new puzzle book. Nemuri was pulled into a conversation with her parents to talk more about her social life to make sure no one was bringing her down. They approved of her friends, but her father was protective over her and didn't want anyone to hurt his little girl.

Aizawa was hanging out in the principal's office, watching as Izuku crawled around fast on the floor. He watched as Izuku stood up after picking up one of his toys before running to him to show it off.

"Ah, it has been a while since I've seen Mr. Sloth," Aizawa commented, ruffling Izuku's hair. Izuku laughed, showing off the little teeth inside his mouth.

He smiled as he thought back to the video Nemuri had sent them with Izuku's first steps. Hizashi is still bitter that he wasn't there to see it. But it was a happy memory nonetheless that they were all going to remember fondly especially since Nedzu had it all recorded from the security cameras in his office as well as Nemuri's video. He thinks she even took some pictures. Since then Izuku has been walking a little better each day. He wonders if Izuku will just disappear from sight if he takes his eyes off of him.

It felt like just yesterday he was saying his first words and now he is walking around. Ah, Aizawa was getting all sentimental. He looked down at the sloth toy as the office seems to grow quiet around him.

The office door opened slightly to reveal his three friends without their parents. Nemuri greeted, "Our parents all met each other and are chatting up a storm right now outside the cafeteria. How's it hanging with little Izuku?"

"Everything is good for once. He has been playing with his toys since I got here," Aizawa explained looking at his friends.

"Well, where is he?" Tensei asked receiving a confused look from Aizawa.

"What do you mean? He's right there," Aizawa said as he pointed to where he last saw Izuku. But his finger showed nothing but empty space and a forgotten toy lying on the ground.

"WHERE DID HE GO?" Hizashi called out loudly in confusion. The friends hurriedly looked around the office to see no sign of the green haired boy, not behind the desk, not next to his toys, not next to the wide open door—

"SON OF A.. HONEYBUN!" Aizawa yelled in frustration at seeing where Izuku might have gone. "Why did you leave the door open?"

"I thought I did!" Nemuri replied, "I didn't close it all the way, but I didn't leave it wide open like that."

"Oh dear, this is bad," Tensei said after he walked up to the empty doorway. "I don't see him in the hallway. Where did he walk off to?"

"Okay, Hizashi, go find where Nedzu is and see if Izuku is just trying to find him. Distract him if necessary. I'm going to head down the rooms of this hallway and stay in this area, so if he comes back I'll be here. Nemuri, you go walk around downstairs and see if you can find him anywhere. Tensei, head down to the parents and see if he shows up anywhere." Aizawa broke it down. The friends nodded in agreement before taking their job positions.

Meanwhile Izuku smiled from his favorite hiding spot in the office. He thinks it will be an exciting game of hide and seek! Izuku hid his giggle as he silently walked off toward where he heard other children. They must be far away, but he will find them and make friends!

"Hello," Nedzu greeted his student as Hizashi sped walked towards where he was.

"Ah! Hi! How're you doing? Is running an event like this calming or stressing?" Hizashi asked, hoping to get Nedzu on a big tangent of some kind.

"What ever do you mean? I like to have these events to show the extent of what UA has to offers. This event allows the family of students to visit and explore the school that their child is attending with little restrictions. It is basically like a tour through the school with the family able to talk to anyone and just have fun," Nedzu explained. "Ah, is this because you wish to pursue into becoming an entertainer as well?"

"Uhhh, yep! Yeah. I wanted to know more about this kind of being a host thing since I want to be a radio DJ. That's the only reason why," Hizashi rambled, trying his best to distract Nedzu. "Anyway, is there any advice you can give me?"

"Why of course! I think I have just the advice you need, but it might be a long explanation," Nedzu informed him.

Hizashi waved it off, "I have plenty of time! My parents are checking out outside with the Kayama family. Please, tell me everything."

"Haha, you might want to take notes," Nedzu added, leading him to a more open area near the cafeteria. Hizashi silently prayed that they find Izuku fast because he doesn't really know how long this Nedzu lecture is going to last. Well, at least he will get some helpful information about what to do in his future.

"Nii-Chan!" Tenya called out as he saw his brother make his way towards them.

"Hi, Tenya," Tensei greeted his brother with a friendly smile, "Hey, have any of you seen a green-haired kid around Tenya's travel near here?"

His mom furrowed her brows, "Is someone missing?"

"No, no! I might just think he is playing hide and seek or something with us," Tensei answered back. 'A game of hiding and seek that we have no idea we are playing!' He thought to himself.

Tensei looked down at his brother, squatting down to his level. "Anyway, I'm just out there looking for him. Do you want to help, Tenya? Izuku is playing hide and seek."

"Find a friend?" Tenya asked with his bright eyes sparkling at the chance to play with his older brother and his first friend.

"Yep! You wanna help your big brother out?" Tensei asked, stretching out a hand. Tenya excitedly grabbed his hand and walked with his brother through the outside. He kept his eye open as he slowly walked side by side with his brother.

It wasn't long before Tensei picked him up in his arms to avoid dragging his little brother behind him since his pace was a bit faster. Tenya settled in his arms quickly, scoping out the area to find his friend. Tenya spotted a head of green hair behind a bush. Izuku peered over the leaves and brought a finger to his lips. Tenya tilted his head at the action before repeating the action back. Izuku nodded back at him, slowly crawling out of his hiding spot to continue walking back into the school.

"Friend?"

"Yeah, we are looking for Izuku."

"Friend went in."

"Izuku went back inside?"

Tenya nodded back at his brother because he can't keep a secret from him.

"Okay, good," Tensei responded back, digging into his pocket to call Nemuri. "Nemuri? Yeah, it's me. Listen, Izuku should be on the first floor right now, more towards the east area of the school. Tenya saw him go in apparently. Yeah. I'm still outside. Alright, sounds good."

"Guess I can be out here for a little longer. Hey, do you want to play a game?" Tensei asked smiling at his brother while on the inside he was screaming.

Nemuri headed straight towards where Tensei told her that Izuku would be, surveying the surroundings to spot familiar green curls. She was about to look around the area for the third time when he heard the familiar giggle of Izuku coming from nearby. For a split second, she could see ahead of curls heading upstairs.

Her eyes widened and tried to follow him only to find out she lost him in the many people in the hallway passing through.

Nemuri texted Aizawa that Izuku just got past her and was heading upstairs. She ran her hand down her face. She hopes they find him soon, she was so worried that he might be hurt while he was running around. Or that they would be hurt for losing him in this big school.

Izuku stumbled his way inside his father's office to go back into his favorite hiding spot behind his papa's desk. Aizawa walked into the office, noticing how the office door was opened slightly more than before, hoping that it wasn't just a coincidence. He was just in the faculty room looking for Izuku for about the fifth time. He had already checked all the rooms on the floor except the office.

Aizawa's eyes swept over the room, notching practically nothing out of place since last time he checked. Meanwhile, under Nedzu's desk, Izuku was beginning to feel like he wanted to end the game already, but he was having fun with everyone playing hide and seek with him.

Aizawa breathed out heavily, sinking down to sit right in front of Nedzu's desk where Izuku was hiding.

He groaned with face in his hands. "Where is he? This never would have happened if it weren't for me. If I would have watched him better as I should have, this wouldn't have happened. But now I don't know where he is if he is hurt. I suck at being an uncle for Izuku." He said sadly looking at the ground. 'If I can't find one kid, how am I suppose to save people?' He thought to himself before glancing out of the corner of his eye to see Izuku peeking over the corner of Nedzu's desk

"Izuku," Aizawa sighed in relief.

"No!" Izuku called out from his spot. "No sad! Sorry!"

Aizawa got wrapped up in a hug by Izuku, who looked on the verge of tears. "Izuku? Are you okay? Did you get hurt?"

"I'm okay! Sorry," Izuku mumbled into his chest.

Aizawa rubbed his curls," next time you want to play hide and seek, let all of us know first. We were all worried about you."

Izuku tightened his grip on Aizawa's school jacket while Nemuri showed up at the office door to the scene before them. She was a bit worried since Aizawa hadn't responded in text yet. Hizashi appeared next with a tired look in his eyes and a notebook filled with helpful advice from Nedzu.

They all joined in on the hug in the ground of the office and listened to Izuku apologize for making them worried. They were all just happy that Izuku was safe now, and a little tired from the wild goose chase. Izuku sniffled softly as they all reassured him that they weren't mad only worried.

Soon, the four joined the pair of brothers playing catch.

"Izu-Chan!"

"Hi, Ten-Chan!"

"You guys, want to grab something to eat since Family Day is almost over?"

"Yes," Hizashi and Nemuri said in a tired unison.

Aizawa watched Izuku play with Tenya as the four friends ate with their parents. Tenya was happily showing Izuku his new book while the two snacked on sliced apples. He made sure to never take his eyes off of him for too long.

'They were a family after all.'

Nedzu sighed as he tucked Izuku goodnight. "You okay, Izuku? You have been looking quite down. Was it because of what happened today?"

Izuku nodded sadly to his dad from under his comfy blanket.

"Well, now cheer up! They were just worried for you, that means they care an awful lot about you." Nedzu explained while fixing up his pillows.

"Really?" Izuku perked up at hearing that maybe they didn't hate him because of the stunt he pulled. He was really worried that he might not play with them again.

"Yes, really. I consider them a part of your family. No matter if they are related to you or not. They will genuinely care for you and love you as I do." Nedzu kindly replied with a soft smile.

"Okay. Love you papa." Izuku tiredly retorted as his eyes drooped.

"Love you too, little mouse. Goodnight." Nedzu said placing a small kiss on his forehead before heading out of the room.

'He is growing up so fast.' Nedzu thought as he looked back at his son's room. 'Hopefully, he doesn't grow up too fast.'
