Izuku, Uraraka, and Tenya all felt it was going to be an extraordinary day as the walked into there homeroom. Mr. Aizawa wasn't there yet but everyone else was. Kamanari, kirishima, and sero were messing around as usual. Todoroki was talking with tokoyami as mineta spied on the girl who were all in one corner. Kirishima recommended playing a prank on bakugo which threw him over the edge as he chased down all of them.

Everyone was being themselves and izuku loved seeing it. "Good Morning guys!" he called out to him and everyone turned to look at the three who walked in.

"Good morning!" They all yelled back, with the exception of bakugo.

"Die deku" was all he said menacingly causing izuku to jump behind tenya and hide.

Suddenly someone who looked much older than them walked into the room. She had long curly black hair and had sparkles in her eyes. Even thought she was pretty outstanding looking, no one knew who she was.

"Uh, hi. Who are you?" Tsuyu was the first to ask.

"Oh I'm sorry! Where are my manners? I'm your substitute for this morning. Mr. Aizawa had some…hero business to attend to. You can call me Ms. Eve." The woman said and smiled warmly at the students.

Seeing how not just anyone could walk into this school without being questioned, the students believed that she was really there substitute so everyone found there seats and waited for class to begin. Ms. Eve smiled devilishly as everyone sat, but only izuku noticed.

"Now, today's lesson is going to be very quick sweeties!" she said and clapped her hands. "Now can everyone repeat after me: Youth."

Everyone stared at Ms. Eve confused. Why was she here again? She clapped her hands again. "Come on, I know it's a little different and weird but trust me it's all worthwhile. Say it loud and clear: Youth."

Everyone (Except Bakugo) repeated the word loud and clear as she asked "Youth."

"I need everyone to say it together! You, spikey, say it!" she said pointing right at bakugo. Everyone giggled as he scowled.

"Okay! Okay! This is dumb." He gritted his teeth.

"Let's try it one more time children. Say, youth!"

"Youth!" this time everyone said it in perfect harmony all together.

"Okay that's enough of that." Ms. Eve say and she snaps her fingers and drops her positive smile. She walks over to the window and stares back at the students.

At first they all stare at her confused, but then they start to feel weird and are no longer focused on her, but on themselves. Izuku was the first to see it, he was getting…smaller! He seemed to be basically shrinking out of his close and he looked around realizing he wasn't the only one. Everyone in the room panicked…until they hit the point that they couldn't panic anymore…

That morning, All Might was a little late coming into work, but he still couldn't help but feel like it was going to be a good day. As he entered the school, he greeted one of the security guards that recently started.

"Good morning young lad!" All Might called out to him. He instantly stood up straighter and waved hard.

"G-Good morning, All Might sir!" It was beyond clear he was nervous to see All Might.

All Might laughs his mighty laugh before answering. "No need to be nervous friend! You'll do fine here!"

"T-Thank you sir!" the guard said and smiled warily "Oh by the way sir, someone was here to see you? She said she was Mr. Aizawa's substitute but I found that weird because I was informed that you'd cover for him. She said her name was Eve."

All Might turns to look at the guard before entering the elevator. "Eve? Where is she now?"

"I think she headed upstairs sir to your classroom. Sorry if I wasn't supposed to! I suck at this already." The guard started to mope.

"Cheer up friend! It's alright to make mistakes because we learn from them! Once again, you'll do great work here!" All Might said returning the smile to the gaurds face before letting the elevator doors close.

As the elevator went up, All Might thought about who this Eve person could be. The name sounded familiar he just didn't remember the face. But suddenly it came to him. He remembered dealing with someone years ago named eve. They were a villain! Realizing this, All Might's heart sped up as he took ou this phone and dialed Present Mic.

After a couple of rings, he answered. "YO!" he yelled into the phone with his screaming voice.

"Hizashi! No yelling right now! I need you to look up the villain by the name of Eve and tell me what you get, I'm in a hurry so I must go, please bring me info soon!" all might said quickly into the phone.

"You got it!" Present Mic responded and hung up. All Might had reached the floor of his class and he dashed to the room. When he made his way to the door, he was actually nervous to open it. What if something happened to the kids? Were they able to hold there own? Was this even the same Eve? Either way, All Might had no choice but to open the door.

However, when he did what he saw shocked him beyond belief. All of his students…were these tiny, little, babbling, drooling, crawling babies!

"Oh…my god." All Might said at the sight of them. So much for a good day. When he heard laughter he realized Eve was still in there, standing by the window. "Y-You!"

"That's right All Might! It is I! Eve! You remember a couple of years ago when you took me for a joke? Well look who's laughing now!" Eve said as he smiled menacingly. All Might walked towards her but she pointed to something in the corner. "Better not worry bout' me and more on these babies."

All Might looked to where she was pointing and his heart almost stopped. Baby Kaminari was on top of his desk sucking on one of his fingers. He spat and giggled as if everything was okay, but little did he know he was on the edge of his desk. If he were to lean back it could mean death for someone so young. The crazy part is that's exactly what he did. A fly had flown by kaminari and he was immediately fascinated by it. He reached his little chubby arms up which caused him to lean back.

Instantly, All Might was across the room, careful to avoid the other babies as he caught kaminari before he fell. Kaminari looked at All Might with a serious face for about five seconds before he started to clap and giggle again. All Might sighed but quickly tensed back up realizing that Eve was still a problem.

When he turned back around, Eve was gone. She must've gone threw one of the open windows and fled. This truly struck fear into All Might's heart. It wasn't that he didn't catch the villain just yet, but it was the fact that all of his beloved students could be stuck as babies for good. He looked all around at them as some giggled, some squealed, some napped, some figured out there quirks, and some just stared out into space.

"Oh boy…" was all All Might could mumble to himself.
