~ Let's Go To The Story ~

The first day at UA was stressful for the students of Class 1-A from their homeroom teacher almost expelling them to their Hero Studies teacher making them fight against each other. But their second day seemed a bit more relaxed as their day started with a reflection on quirk theory.

"As you all know, quirks began to spring up with the discovery of the 'glowing baby'. From then, quirks have only gotten more diverse and complex, but does anyone know of the quirk singularity theory?" Izuku lectured as a picture of the glowing baby and a few pictures of heroes using their quirks popped up on the board. "Fine, Izumi tell them."

"U-um, quirk singularity theory, right?" She asked as she was caught on her phone but Izuku nodded with a poker face the whole time. "It's a theory stating that quirks will become so complex that none will be alike through the mixing of quirks at birth."

"That's correct. For example, Todoroki's quirk is a mixture of fire and ice manipulation." He said once again as Shoto Todoroki looked uncomfortable. "But I've studied quirk development throughout my years at UA, which led me to my own theory: Quirk Reset."

"What?/Huh?" Were just some of the reactions to Izuku's theory.

"To put it simply, I believe that every 10 generations, all quirks will revert to a primal form. So the complexity of some quirks will be diminished, allowing someone like Katsuki to create explosions anywhere instead of just his palms."

"Sensei, what generation are we?" Momo asked with some concern in her voice.

"You are the tenth generation, so I believe an event will revert your quirks or your children's quirks will be reverted. But since these theories will be irrelevant in battle, let's go back to quirks." He said as the class woke up from the boring theory discussion.

"We were already taught about quirks in junior high." Complained Denki as he leaned in his chair.

"Then I'll talk about Quirk Development and Evolution." He said as some students perked up. "As you use your quirks, they will continue to get stronger like a muscle. But in some rare cases, quirks have evolved into different and stronger versions of themselves."

"Does that mean my quirk can evolve?" Asked Mina Ashido excitedly.

"It's possible, but I believe your quirk will adapt to your body more. Which would allow you to secrete acid from other sections of your body." He answered as the bell rang. "Well, I'll see you later, but get ready for some training later." Then he left the room to do who knows what.

But the other classes seemed quite similar to yesterday, with their teachers lecturing them on ordinary subjects like Mathematics and English. The only exciting thing was when Midnight fixed a collar onto Izuku during History and forced him to turn into a little girl whom Midnight hugged to death and carried while giving her lesson.

After all the normal classes and Homeroom, All Might came into the room without Izuku. "Afternoon, class! Today, we'll be doing training with Cementoss in Gym Gamma. Also, I believe Izuku is running from Midnight at the moment so we'll see him later." He said as everyone grabbed their suit before changing.

In Gym Gamma, everyone gathered in front of Cementoss who had All Might to his right and Izuku to his left. With everyone in their hero suit in front of the teachers, but Katsuki's mask was ruined and Shoto didn't surround his left side in ice.

"Welcome to Gym Gamma or as I call it, Training Dining Land." Said Cementoss as Tenya raised his hand.

"Sensei, why is it called Training Dining Land?"

"This gym is made of pure cement, allowing me to create an area for each student's different training methods." Answered Cementoss as most of the students understood. "Izuku will create a clone for each of you to train with on your own platform if you will."

So, Izuku created 20 clones of himself as the original ran when Midnight entered Gym Gamma. Either way, each student took a clone with them to one of the Gym's platforms before their area rose up and they started to train.

With Izumi, she was stopped from her training as the clone of Izuku had something to say. "Nii-san, what is it?" Izumi asked somewhat annoyed.

"I think you're ready for another quirk." He said simply as Izumi started to beam in joy. "Think of it as a reward for winning. But I have quite a few quirks at my disposal, so I'll let you choose a form of elemental manipulation."

Before answering, Izumi pondered what to choose with her Hyperspeed. "What choices do I have?" She asked to hopefully narrow down her options.

"Okay, I'll let you choose between Water, Fire, Air, Earth, and Electricity. But all of them are in the simple forms, you'll have to train to let them grow so you can control more." He answered.

After another minute of pondering and some muttering, Izumi finally made a decision. "I want the Water quirk." She answered as Izuku's clone pulled out a syringe filled with a clear, blue liquid.

So the clone injected Izumi with the quirk, but as she didn't feel any change she started to practice her Jiu-Jitsu stance and form. She practiced the stance and started to mix her quirk into it so she gained an element of surprise for those who knew the stance.

As for the original Izuku, Midnight somehow caught up with him counting the fact that he forgot to use his Hyperspeed or other quirks in pure fear. When she caught him, she attached the black collar and it somehow turned into a choker before she pulled out a remote.

"Where the hell did you get this thing?" Izuku whined as Nemuri made him shapeshift into a short, black-haired girl with a pair of fox ears and a fox tail, but somehow Izuku's clothes changed too from a green and red suit to a black and white suit with an oversized jacket and a plaid skirt instead of pants.

"Don't worry about that~!" She replied as she nuzzled Izuku's new form between her breasts, much to the jealousy of Minoru Mineta and Denki Kaminari. "Don't ever leave," She sighed out.

"Why shouldn't I?" Izuku asked as Nemuri petted his new ears which he refused to show how much he liked.

"Because you love me. *Izuku sighs*" She answered back as Izuku stopped struggling and let her pet him/her until the end of class where she actually let Izuku go home.

While Izumi went home safely, Izuku returned to his hero agency to get hug-tackled by his personal assistant who had a vampire quirk and loved to suck his blood. Although the author will probably get rid of her if readers don't like her.

"Izu-kun! You're back!" Shouted Mira as she took a bite from Izuku's neck before she drank some of his blood. "Ah~ I missed that taste~."

"Yeah, yeah, Mira so why did you call?" He asked as he picked her up and set her on her own two feet before she pouted.

"Well, we got some new intel from our spies in the red district, have a few press events, and a photo shoot with Uwabami."

"Let's talk about that intel privately."

~ Sorry! That's Private! ~

A/N: This chapter is a bit short, but I'm making three chapters at once so I can relax during a road trip. So after chapter 7 everything should be back to normal.
