Izuku the prince of the devils

The horrors of Serafall pt1

Izuku and co made it to the Leviathan mansion, where Serafall lives. He remembered the last time he was here and oh boy he hated it.

Flashback:

It was morning and young Izuku was there because of the fact that Serafall took a bit of his training. He was having a good dream of were his mother had given him the best Katsudon in the world before his door was thrown across the room.

"it's time to get up!" Serafall ran into the room and shouted with joy as she jumped through the doorway.

"ramen is not as good as Katsudon" Izuku spoke in his dream while Serafall grew a tick mark and pouted.

"you have five seconds to get up or else I will do something I will regret" she spoke while Izuku didn't hear a thing.

She slowly counted down hoping that he would but in the end he didn't. She then did something she did not want to do but it would engrave itself in his memory.

She jumped in the air but then somehow lost her balance (anime logic) and came crashing down on Izuku as he woke up to see Serafall behind hit his face. She was not wearing panties.

Flashback end:

Izuku shivered remembering the beat down he got from her after she thought he was a perv. His mum was not happy.

"here we are! Were Ser-tan lives!" Sirzechs was clearly excited about his visit while Izuku quietly hoped she was not in. He knocked on the door.

"She is scary. Very scary" Izuku thought to himself about that only the training and then they heard her.

"I'll be there soon!" Serafall shouted before opening the door and seeing them all "welcome to my mansion!" She shouted with lots of joy.

"Well we will be here to train, so Izuku you're coming with me and the rest go with Ser-tan" Sirzechs said while walking inside.

"I am going to regret coming here" Izuku said while being dragged inside by his dad.

"Don't he silly! Today we will have the best father and son training!" Sirzechs shouted with joy and Izuku rolled his eyes.

"Dad your definition of fun is annoying Micheal"

"We both enjoy doing it, don't lie" Sirzechs told him and Izuku sighed in defeat "anyway todays training will be super cool. I will teach you more ways to destruction magic"

"Why isn't mum here to teach me ice magic?" The red- sliver heard boy asked.

"I just wanted some father and son time"

"Wait does that mean we get to do what we want!"

"Your thinking what I am thinking?"

"Let's by a bunch of rabbit statues/cat statues!" They both looked at each other before Sirzechs smiled proudly.

"I see, you are a devil of culture as well" the red heads then brought around about two hundred statues of what they wanted, to say Grayfia was pissed is a understatement.

Timeskip:
Location: Underworld, Leviathan mansion:

It was now the second day of training and he got to train with Serafall. Currently we find our main character in a military ground with Serafall.

"If you even stop for a second, I will break every bone in your body!" The only female king ordered Izuku with a stern voice.

"I swear you and Aizawa are some sort of secret siblings!" He screamed out, while a candy cane haired boy suddenly felt he was missing out on some quality theories.

"I don't know who this Aizawa is but he sounds like a nice guy" she said with a question mark appearing above her head "is he single?"

"What!?"

"Nothing" she whistled innocently and Izuku sighed, still having to do five more laps around the whole course, that looked like a whole military base itself.

Izuku finally finished and fell down, exhausted because of the crazy devil. Serafall walked over and smiled "most people can't do that, well done. Your girls must get exhausted before you"

"Why do you say these things?"

"Because I am Serafall, you shall respect me in every way" Izuku got up and looked at her before sighing.

"Can I go?" He asked and she pouted.

"Do you already want to leave your aunt Serafall?" She said with puppy dog eyes and he gave a smirk.

"I'm a cat person"

"Well then you have to run sixteen times around this field before you leave!" She said in a commanding voice.

"Hey aunt do you know that there is a crazy drunk fat man with a gun fighting a gorilla in Australia right now"

"You think I am going to fall for that?"

"I am honest"

"Fine but if you lie then so help Lucifer that you live"

"I am right here though"

"I mean the actual Lucifer. Lucifer Morningstar"

"Oh" she teleported away and Izuku waited for her return.

Timeskip: a few hours later:

Serafall returned and looked at Izuku "it was real and sadly it was the most interesting thing I have seen in years"

"What happened?"

"The gorilla grabbed the gun and shot the man, but it was deflected because of his fatness and shot the gorilla, and then he jumped onto the poor thing, causing forest fires" she told him and he looked shocked.

"Your telling me twenty twenty had forest fires because of a fat man jumping!?" He screamed and Serafall nodded "I'm going to sleep after lunch"

"No you still have magic training"

"Fuck you"

"We can do that"

"What?"

"What?"

"No"

"I think yes"

"I don't like we're this is going"

"I do"

Timeskip:

"It's way to big!" Serafall shouted.

"Well if you stop moving this can be more easy!" Izuku shouted at her.

"But it won't work, it's way to big!" Sirzechs opened the door and saw Izuku trying to put a life sized bear statue threw a portal Serafall made.

He looked on and sighed "need help?"

"No this statue will get through!" Izuku shouted before straight up punching the statue, destroying it.

"You have to pay for that" the two devil kings told him and he gained a depressed arua.

Timeskip:

"Izuku!" Akeno shouted, entering the room "can we have some fun~?" She asked him, seeing Izuku right next to a cat statue with his dad next to a rabbit statue.

"Listen son and listen carefully. Once you have a favourite animal, it stays forever!" Sirzechs said with tears, wiping them away. Izuku was confused by his words and shrugged before seeing his dad with a guitar.

"No" Izuku said in disbelief as his dad started.

Enjoy this for now...
