Izuku was meditating, one of his favorite things to do. It helps him keep a calm mind when things get out of control. Azar suggested this to him in controlling his emotions, and surprisingly it did work. The books that he read were about the history of Azarath society and how it functions as a peaceful race, wanting nothing to do with violence so they cast out evil and put it somewhere else. He also learned about the magic that has been here for centuries.
He was fascinated with magic and what he can do with it. Izuku visited Azar and went to her temple "Hello Azar" he spoke in a monotone voice "Hi Izuku how are you" she said he replied that he was good and asked "where is my mother" she replied by pointing at the house that was in a cliff. He was going to talk to his mother to see if she needed anything from him. Even though he could not show his emotion physically he could shown them mentally, without blowing something up by accident it always happened and whenever it did he always got Embarrassed,
"Hello Izuku" Inko said "Hello Mother how are you today" he asked she said she was good just doing chores in the house, now Izuku knew of quirks and how they came to be because of the one missing pinky joint in the toe, Izuku found this stupid since he questioned how a single pinky toe gave someone a Quirk, but whatever he theorized that was he was Quirkless, but it didn't really matter because of his unique bloodline. He knew he was human, but he suspected there was not all there was to it he was probably something else as well.
It's been 10 years since he was born and he learned all about his powers since then he learned he could manipulate emotions, shoot energy blast, create energy shields, light magic dark magic phase through objects and probably do more. He might have more powers to discover but one thing was for sure his mother always said that people only had one quirk. But it was obvious that he had multiple quirks and was something more than human.
But there was something that bothered him, whenever he asked who is father was she quickly dodge the question and put his focus on another thing, Izuku wasn't stupid he knew that his mother was hiding something, and knew that if he wanted answer he would need to get from the Library. So when got to the library, he looked through the library and after a few minutes of finding nothing, he found what he was looking for,
"Oh this is interesting" as he looked at the book for the answers he read about a demon who was named by Trigon, it was stated that this demon was a powerful entity. Once he was done he went back to training his powers, So he began to meditate for his training. Once he was done with that, he began to go to Azar and speak to her again.
"Hello Azar can you tell me, about the demon Trigon". Azar said shocked "how do you know that name". "I've read about it in one of the books that spoke about a Demon named Trigon". "That book is dangerous knowledge about the one who shall not be named. I recommend not touching that book because of the knowledge it holds".
There was something that Azar was holding back information. But let it go not wanting to upset Azar so he nodded and went back home to his mother. "Hello Izuku, how was your day?" Izuku told his mother. It was nothing special, just meditating while reading books. So he went to sleep. The next day Izuku wanted to know about his father so he went back to the library and read the book that had forbidden knowledge of the demon known as Trigon. He got the information that he needed and he did the ritual.
He copied the ritual as a circle with a star in it and some candles and lit it up. Once the ritual was the done, the sky turned red and red lightning shot out, What appeared horrified him to the core because what came out was four red glowing eyes and a silhouette that formed into a 58 feet tall red Demon that was intimidating to look at and had to be in Izuku's eyes as his father.
Everyone in Azarath was screaming and running away. While Inko looked up in shock and terrified for Izuku's life. Trigon looked at his son and smiled evilly at him and raise both his hands and red energy started to destroy everything and everyone, including Inko. Izuku was shocked and yelled out then something came out of him, his soul self manifested and looked like a Giant dark Raven but this soul self was dark purple and enclosed Trigon, he tried to everything in power to break free. but eventually the gem on Izuku's forehead came out and sealed him in it. When everything was said and done Azarath was destroyed by Izuku's father.
The gem that was in his forehead dropped down. Izuku picked it up and put it back in his forehead, Izuku laid there crying for minutes or hours. He didn't know how long he was crying. But he was there for a while. Once he was done he opened a portal and stepped through it into the city of Japan. He looked around and was in awe of the city before him, his mom always talked about her home in Japan and how beautiful it was and he is not disappointed in the slightest. He walked around Japan and there were people with odd features, which he assumed were their quirks.
There were pro heroes he recognized from when his mom read him books of the heroes in the world, he wasn't some hero fanboy who carried books about heroes and villains quirks or have all Might themed merchandise in his room. But he respect heroes. Izuku walked around for a bit until he found a flatscreen that showed all might saving civilians, standing on top of the bus with a big smile on his face. "It's fine now. why? Because I'm here!" Izuku stared blankly at the statement all Might said "what a cliche line all Might". He walked away when he heard a scream in an alleyway, he began to investigate and saw a girl in a ponytail and mugger holding a knife to her throat. saying something about money. Izuku eyes glowed white and chanted "Azarath Metrion Zinthos"
as dark energy shot out from his hands and shot the guy knocking him out. The girl looked at him as he walked away, until The girl shouted wait as he stopped and turned his head. "Thank you for helping me. What's your name". "Izuku Midoriya and You're welcome, what's yours" Momo Yaoyorozu" "see you Yaoyorozu". As he flew away.
