Issei is sleeping on his bed with his harem, which include Rias, Akeno, Assia, Xenovia and Koneko. One can say he was lucky, he has a strong power than can rival god itself and multiple beautiful women but that night something happened that will change his life forever. As we all know Issei is a massive perv, he has an ultimate move of making his oponent naked and one individual inside of him will disagree massively. That individual is the mighty red dragon emperor Ddraig. He was being made fun of by the other dragons due to his host, but thats not all, his rival Albion doesn't want to near him and even fight him. The fact that Issei was praised after the kokabeil attack and that fame got into his head made things even worse and that continued for a long time. Those events made the one powerful dragon which was feared by many something to be laughed at and he didn't like it at all, after a couple of months he just wanted to leave, so he created a plan, he was secretly gaining energy to escape and one night when Issei and his harem was at home he left sleeping.

Ddraig 'Finally I am out of this body, it was interesting knowing you Issei Hyoudou but I hope we never cross paths again' the green orb was then gone from Issei.

Izuku was a quirkless child with a simple dream, to save everyone with a smile like his idol. How naive of him you would say as the person which he looks up to is the number 1 hero All Might also known as Toshinori Yagi. The problem you see is that Izuku was mistreeted, why because in the eyes of Toshinori, Inko and his sister Izumi he was worthless even though Toshinory was quirkless. But as you know if life gives you lemons make lemonade, and you will see what I mean later on. As now we go a couple of years before Ddraig left Isseis body.

We go to Izuku, currently a 10 year old eating breakfast. Only his so called father was home that day in the morning. He was making breakfast as he was still resting from the mysterious car accident not allowing him to do his 'work', Toshinori was preparing breakfast for his princess. You might say hey he's a good parent but no, both of Izuku's and Izumi's parents kept forgetting that Izuku was there and he is their son. Izuku on the other hand knows that and looks after himself and that how he lived. Enough rambling now lets go see what is happening.

Toshinori "Izumi, I made breakfast."'my hours are going away, I need to find a successor soon'

Izumi "Thanks pops", Izumi a twin of Izuku and one of his school tormentors, she has a strong telecanetic quirk.

Izuku 'I think I could finish of some of the food that dad left' and so he ate it as there was no tomorrow but during this time he didn't realise that he accidentally ate something which was a peice of hair from All Might. Then he goes to school, the walk to school wasn't long but he wasn't happy about going their either way due to Katsuki and Izumi. (I hate writing about his middle/junior high so Ima time skip) The day was the same with his classmates bullying him but one thing made itself in his mind. The words that Izumi said, "if you really want a quirk, take a dive from the roof and hope in your next life you will get a quirk." That was something that broke him as why would a family member say that to him, luckily when he went home no one was there for the night as Izumi went over for a sleepover and his dad was with his mom. When Izuku made dinner for himself he was thinking over everything of what had happened in his life but then he heard some voices in his head. Izuku being a curious green bean wanted to talk back.

Voices inside his head "Hello Izuku Yagi, we are the voices of One For All"

Izuku "heh!!! I have a quirk?!?!"

"Yes you do but you need to escape this household"

"why though?"

"I think you need to listen to this first"

"okay......."

And so the past users told Izuku how the quirk was made and that his dad is All Might and the goal of the quirk, they also recommend that Izuku starts a new life as if All Might discovers it about the quirk bad things may happen. Izuku does make sense of this and so he started to pack his non-allmighty clothes and the money that he saved up, he also filled a bag with food and left. The 4th user told Izuku about his house in the mountains few towns over and so the adventour of Izuku Yagi starts.

The train rides, the walk up the forested mountain to get to a small cabin which looked something like this but with a water wheel:

Izuku "this is a nice place"

4th "Thank you, you can power up the water wheel to produce electricity then you can relax and we will all help you with this quirk and the problems that may occur"

"Thank you so much"

Izuku then powers up the water wheel and then unpacks and explores the surroundings. Later on the day Izuku asks the previous users of how will they train him.

7th (Nana) "Training will start tomorrow so you can actually use this quirk, in the meantime your education will be continued online so you have to go to the library. Additionally we will teach you how to survive"

Izuku "Thank you so much"

And so he does, he traines every day with the help of the users and the education is too going well. He goes to the library and actually learns without having his grades sabotaged and no bullying. He upgraded the house to help during the winter periods and he does help the people living in the small town and earns some money. All is going well, he can spread OFA around his body by his 4th month away being at 3% and continues to do his things. (I dont want to bore you with this training arc but there will be another training arc with a mythical being soon). After 2 years and gaining 40% of OFA the past users and having 3rd teach him martial arts he does look fit compared to any other 13 year old, but then he discovers that he can use other users abilities firstly being black whip, next is float, danger sense, smokescreen, fa jin and regeneration (2nd users quirk, I don't know what it is but it can heal any injuries but it is slow for example a broken bone in a day, a cut in a minut and so on) and those took an extra 3 years to master.

Now being a 16 year old having control of 60% of OFA and 6 other quirks under his bag and UA starting in just less than a year. When he was sleeping, he was in his mindscape where he usually meets the past users but this time he saw this:

Ddraig "HAHAHA so this is my new host, it is better than I expected."

Izuku "heh?!?! I have a freaking dragon in my mind scape?!?! what else devils will come after me?"

"Probably, but let my introduce to you I am Ddraig and you are my new host"

"ehh, okay. Hi Ddraig I am Izuku"

"Don't worrry child I saw your memories and the spirits of OFA are nice"

"So what will happen now?"

"Now my child I will teach you how to use the sacred gear and spells"

"What is a sacred gear and what do you mean by spells?"

"Oh yeah so sacred gear is similar to a quirk and spells happen when you put your energy and a magic circle appears and you can do multpile stuff"

"Nice but can we start in the morning?"

"Sounds nice partner" 'He is way better than my partner'
