Izuku harshly trained his new students with many unorthodox methods. The most notable one being pushing them all off a cliff into ice cold water.

He was forcing their lungs to expand by consistently making them breathe in a certain way. If you broke the concentration he would wack them with a stick. His one rule was no quirks.

"Hey kid! I'm here for a rematch!"

He turned to feel a familiar presence "Not now bunny! I am training my students!" He shouted at miruko pissing her off. "I ain't taking no for an answer!" She shouted launching an attack at him.

Izuku used his stick to redirect her kick to the ground and made her fall on to her back. "I said not now bunny." He stated as he watched his students run.

They were improving, but he could see that some could not keep up. He took note about it to fix their schedule.

Miruko got up pissed at herself that she was on the ground so fast. Her licence was suspended for fighting a civilian. So she went to nezu to get a partial license as a trainer and hero.

"So what are you exactly training?" She asked him sitting up. "Them!" He said pointing at his students. "Lunch told me to train them so that's what I am doing! Fuckin small fries!" He shouted as they ran faster trying not to piss him off.

He turned to her "Want to join?" He asked "I am already at my peak training will only keep me at that peak not higher." She stated.

"Wrong dumb bunny."

"The fuck you just call me?!" She said gritting her teeth. "When we fought I could tell that you still had lots to grow." He answered ignoring her question.

"W-Wait really!?" Miruko asked him "I want a good rematch so I need you to be stronger. So do you want to be stronger?" He asked sticking his hand out.

She took his hand and with a crazy smile "Fuck yeah! When do I start!!!!" She asked "Right now!!! Three hundred laps go!!! No slowing down full sprinting!!!!" He shouted as she took off with great speeds.

Izuku took off his mask to see her lap the entire class. He looked at his hand and stuck it out to the sun. It burned away almost instantly. "Fuck the sun! I am damn king of the flaming forest!" He shouted regrowing his hand.

Once the class finished their laps he walked them up a near by mountain that he made the night before with his giant serpent mode. He personally filled it with trap.

They stayed till nightfall with izuku watching them. "Um midoriya why are we up here and last time I checked U.A. didn't have a mountain yesterday." Kaminari spoke up.

"You all have till dawn to get down from this mountain or your training gets tripled. No working together." He stated running down the mountain.

"That's it! This is going to be easy!" Sero said excitedly. He began running down not even a couple seconds later he fell into a pit.

"This deku we are talking about so he trapped this entire mountain." Katsuki says taking a step forward then leaning back dodging rocks. "Can't be that many!" Mineta shouted getting pelted with rocks. "I haven't even moved!!!"

Izuku ran back to see that miruko finished the laps. Her legs were shaking badly "What's next...." She said tiredly. She collapsed so izuku picked her up.

He went to the dorms and placed her on the couch. Izuku then went up the stairs to himiko's room. There he stayed waiting for her to awaken. Eri laid in her bed hugging her as she slept as well.

"Big bro I have to show you this!" Kota shouted bringing him his sword. Izuku examined the blade he had given him back at them camp. "What's wrong with it?" Izuku asked kota.

"Nothing! But look at this!" Kota said excitedly. He took off the hilt shape like a flame. To reveal a roll off paper paper that looked old. Izuku unrolled the paper to see an array of moves that seemed like a dance.

"Dance of the fire god?" Izuku read on the paper. "Uh huh! I looked at it! It looks like your flame breathing, but more refined!" Kota shouted performing the dance as izuku watched.

It was as if he was watching a spirit dance as kota did the moves accurately. He smiled as kota finished "I think you should use this big bro! It would make you better than you already are!" Kota stated.

Izuku rolled up the paper and placed it back in the secret compartment. Then readded the flame hilt. "It's not mine to use kota. I gave you the blade so whatever was in it is yours to use not mine." Izuku stated giving kota back the blade.

"But.....I want you to be the strongest." He says looking down "You will be stronger than me one day so use this to get there faster." Izuku said patting his head. "What about me papa?" A now awake eri asked him. "You too will be stronger than me. Which ever of you is stronger is up to you two to decide that."

Then he heard both of their stomachs rumble. "Looks you two are hungry so lets eat." Izuku said smiling picking them up. He took one final look at himiko and shut the door.

'Wake up soon himiko. I will be waiting for my one of my top disciples.' Izuku thought as he made soon grilled meat for the kids.

"Eat the meat! You need it to be strong!" Izuku yelled as the two dug in. Eri was getting better with her quirk because of her training with izuku. He used himself as the test subject to show her that he fully trusted her.

Kota was rapidly getting better at wielding a blade. Much to izuku's excitement and eri was picking it up as well just as fast.

"Papa, will I get a mama soon?" Eri asked him "Is that a food?" Izuku asked her. Kota kept his mouth shut for the fact he knew she was asking for. Lets say pixi-bob didn't really keep it pg around him. Much to his aunty's disapproval.

"Mama! Like a wife for you!" Eri said excitedly. Izuku thought about it as many women that have capture his attention for being strong and feisty appeared into his mind. His nose began to bleed as he thought about their faces.

"Again!" He said to himself wiping his nose. He didn't understand why it kept happening to him. "Eri maybe one day soon." Kota answered her as she nodded.

Eri looked at the drop of blood that fell from izuku's nose. She dipped her finger in and tasted it before kota could stop her. "Blegh papa why do you drink blood it tastes nasty." Eri said sticking her tongue out.

Once they were finished they sat on the couch watching tv. Izuku held kota and eri close as they fell asleep. He smiled as they clung to him. "Can't wait to see you two grow up." He muttered imagining the future he wants for them. To be ruling the world with an absolutely no chance of beating them.

That was the future he wanted for his perfect heirs. The door from the dorm house opened wide to reveal a very dirty and bruised kyoka jiro.

"I m-made it!" She says collapsing on the couch next to izuku. "Where are the others?" Izuku asked her. "Half way to the end." She gasped for air. The mountain had thin air, that alone made it hard to breath. It made sure that you breathed correctly or you would pass out.

It also helped that jiro was the fastest one he has taught surpassing himiko's top speed.

Jiro peered at him and smiled "You know you're a good dad to eri." She said patting his head feeling his fluffy hair.

The moment she touched his head his nose began to bleed then promptly passed out. Shocking her "Ok looks like contact with girls knocks out the mighty king." She muttered getting up and grabbing a blanket and napkin.

She wiped his nose and wrapped them in a large blanket. She snuggled close to him and shut her eyes. Eri opened her eye to watch her. 'Potential mama! Gotta make sure she's nice with papa!' Eri thought shutting her eye and falling asleep.

Katsuki got up with multiple rocks pelting his back. "This is nothing! I will be the best! I will become the number one hero!" He shouted destroying an incoming log.

The rest of the class weren't fairing any better for the fact it was getting hard to breath. Needless to say some were thinking of quitting. Though there were of few learning and quickly adapting to the situation.
