Enter, Hadrian Antares Potter

XXXXX

This is a world of heroes and villains, those who enforce the rules are called heroes, while those who don't want to be restrained by the rules are called villains. A distorted world where the concept of a hero has been broken, the Hero who was once a nickname given to those who are willing to suffer so that others are happy, willing to cry so that others laugh, willing to be alone so that others are with their loved ones, willing to be sick so that the others are healthy. That's the definition of a true hero.

This world glorifies Quirks where those with strong Quirks are revered and those with weak Quirks or no Quirks are despised. Unfortunately, with the current world population consisting of 80% of people who have a Quirk and another 20% who don't have a Quirk, this creates various harassment for minorities.

Quirks are generally inherited from a child's parents, the child will get one of the parent's quirk types, those who do not get their parents' quirks are called blood-borne mutagens after several generations. The number of mutagens in the world is very small because the Quirk itself is created at the same time as the DNA of the child during the fertilization process occurs. In special cases, some children get both types of quirks from their parents, which are called G-Mutagens or Gold Mutagens. The G-Mutagens especially those who get Quirks of the opposite sex from their parents are considered special in Quirk research. Because many experiments have been carried out with the result not far from death.

There are many cases of parents wanting strong children by doing Quirk Marriage which is an illegal ritual because it can harm the child which unfortunately is still often done today, even many heroes who carry out this forbidden ritual.

Potter's Castle

"Haah... Haah... Haah..."

Hadrian Potter, who had just turned 15, woke up gasping for air, cold sweat running down his naked body. He felt a headache that he had never imagined before, he got memories from his previous life as Harry James Potter. His life was not easy, the betrayal of his friends and the wizarding world did not surprise him, he was not as stupid and naive as people imagined. He realized that he was manipulated from the start, therefore he had been prepared if anything untoward happened, he made sure to take all the assets he had since his third year at Hogwarts he realized that he not only inherited the Potter Wealth but also the 108 Families. others either through blood, magic, or inheritance from other wizards as thanks for defeating Voldemort.

His head throbbed when he realized that he had returned to his consciousness, he gathered the fact that he had been reborn in another world as Hadrian Antares Potter who is the first son of James Potter who is a 2nd Hero who has the nickname Transfiguration Hero because of his skill to change anything with her Quirk so that he can shift Endeavor who used to be ranked 2nd and Lilianna Potter nee Evanese who is a 5th Hero who is nicknamed Lady of The Pigeons because of her ability to control pigeons so she can use the pigeon's abilities and turn into a dove. He was surprised to find the fact that he had 36 younger siblings, James Potter was a playboy in this world, he married Lilianna Potter and 15 other concubines. He didn't mind, he always wanted to have a big family. His grandfather and grandmother Charlus Potter and Dorea Potter nee Black are still alive in this world, he has one uncle and one aunt named Aiden Potter who married Manami You and has a son named Shindou Potter. Her aunt is Roselia Potter who married a businessman named Midoriya Hisashi and has a son named Midoriya Izuku.

"Looks like I can't sleep anymore" Hadrian muttered as soon as he looked at the clock on the wall which showed 4 am, he immediately used a sleeveless shirt and boxer shorts to cover his naked body, he didn't know where Hadrian Antares Potter had that naked habit, maybe his father who also has a hobby of being naked while at home which makes him shake his head. Even though Hadrian also has a hobby of being naked, he never gets naked in front of his younger siblings in contrast to his father who doesn't care who sees him.

He then went to the training room owned by the Potter Family House, the Potter House is a traditional Japanese house in the form of a large and spacious castle. The Potter family is very rich in Japan, the Potter family controls more than 60% of the Japanese economy, the talents and strengths of each member of the Potter family make this family respected and feared by many people, especially the enemies of the Potter family.

Hadrian Antares Potter's Quirk is in the form of a Core containing magical power and knowledge called the Quirk Magical Core which allows Hadrian to know and use many different magics so Hadrian's Quirk is also dubbed the Multi-Functional Quirk which will only exist once in 100 years. Moreover, Hadrian has experience in real combat where life is at stake so that the practical ability of Hadrian's Quirk becomes stronger.

Hadrian ran around the 500-meter training room for approximately 1 hour long, he then did 100 Push-ups, Pull-Ups, Squat-jump and Sit-ups each, he didn't have time to exercise in his previous life, now he can do what he wants. Although he is 15 years old, his physique is fit and healthy, his face is handsome, his talents are many and his mind is intelligent, which makes many people admire him, he often goes back and forth into magazines and films as an artist and model. Therefore, even though he was only 15 years old, he already had his income which made the Potter Family name increase.

He will enroll in the school with the best hero major in Japan, namely UA in a few months. He wants to be the best hero to replace All Might, who is declared the best hero at this time, neither he nor the other Hadrians believe in and will never believe in All Might. According to them, no one is selfless in this world, neither is All Might. As a result, after a long search they found that All Might was responsible for the deaths of 213 children who were declared to be Quirkless, he was also often late for rescues, resulting in the deaths of 342 people. Innocent, Obviously this information is kept secret from the public so that only high-ranking officials in Japan know about All Might's sin.

He will make sure All Might and the corrupt Politicians pay for their sins by dragging them to hell, he doesn't want any more children to suffer. He had suffered enough that he would not let any children go through what he had. Like him, the owner of his body also thought the same thing considering he founded an orphanage as well as an educational institution for people, especially children who were grouped as Quirkless. He hates people who insult other people just because he has flaws, he doesn't understand why no one thinks that everyone has their strengths, of course, Quirkless also has advantages that those who have Quirks may not have.

"Haah... Haah... Haah..."

He was panting, his body covered in sweat. Hadrian glanced at the clock hanging on the wall of the training room, he saw that it was already 9 in the morning. Saturday and Sunday are holidays for Japanese workers and students, including Hadrian. Therefore, he did not need to rush to end his practice. The time he spent learning various magics after the 2nd wizarding world war with Voldemort was very valuable, until the betrayal he had expected came even though the betrayal happened later than he expected.

SYUUT

The sound of the door opening made him suddenly look at the door and find a small, disheveled red-haired boy looking at him with a smile that made him smile softly. "What are you doing here, little one?" asked Hadrian. The child was named Akashi Potter, one of Hadrian's half-brothers. Akashi has blood red hair, white skin, his body is also small, besides that, he was also diagnosed by doctors as a Quirkless, Akashi is also the reason why Hadrian Antares Potter founded an orphanage and educational institution for Quirkless. He wants his sister to live life without being hurt just because she doesn't have a Quirk, even though Akashi doesn't have a Quirk, he has a sharp mind that often helps Hadrian in puzzles that Hadrian sometimes fills in his spare time.

"Nothing, bro" Akashi replied hugging Hadrian, he inhaled the scent of Hadrian's sweaty body. Even if Hadrian knew, he didn't show it and let his dear brother hug him, he knew that Akashi had a hard time interacting with the other brothers because of his shortcomings. He wants to protect his brother, he is an older brother, it is the duty of an older brother to pamper, protect, and love his brother. He shook his head every time he read or watched the news about an older brother hurting his brother, he who used to live and suffer alone was angry with an older brother like that, he always wanted to have a younger brother to love and protect, but because circumstances that made his expectations impossible.

Hadrian lightly kissed his brother's forehead, he chuckled softly at the distaste in his brother's red eyes, he knew for sure that even though his brother was still small, he had tried to act mature which made him look even more adorable in Hadrian's eyes. Hadrian then carried Akashi with a small laugh, he brought the 8-year-old child to the dining room at the Potter residence.

Lord Potter's Room

Lord Potter's Room is the largest room in Potter's castle where Lord Potter and all his spouses sleep. The room had 10 King Size mattresses combined into one. The room has a mix of dark colors coupled with soundproof walls so that activities in the room are not heard until it comes out, there is only one lamp in the 100-meter wide room, and even then the lights are dim, The room is filled with candles that emit an aroma that stimulates the libido so that Lord Potter and his Beloved can enjoy each other's time without worrying about their appetites dropping.

Currently, Hadrian is being summoned by his father who is the current Lord Potter to report his progress, he doesn't mind reporting his progress, it's just that he prefers not to report his progress when his father is making love with all his girlfriends, he's sick of it. The pungent smell that couldn't help but stimulate his libido, he didn't want to smell his father's sweat and semen that filled the room.

"How was your training, Hadrian?" asked James Potter, all around him his wives and concubines touching his naked body without caring that their children might see what they were doing. "Fine" Hadrian answered coldly, he still hasn't forgiven his father for being rude to Akashi who was diagnosed as Quirkless. "Good, you know what it would be like if you tarnished the Potter family name, right? It won't be good for your brother," said James Potter, holding back a groan at the licks his concubine had given him on his dick and nipples.

"You don't have to worry about me, Dad! You better worry about yourself, it won't be good for you and all your mistresses if grandpa and grandma know what you're doing" replied Hadrian with a cold smile making James Potter and all his wives and concubines freeze. They clearly remember what happened when they made love outside the room and it is known by both James' parents, James and all his mistresses can't forget that day, they can't sit for up to 2 weeks long, no matter how much healing drugs and Healing Quirk users they use.

"GET OUT" shouted James Potter frightened which made Hadrian smile a little, he glanced at all the concubines and wives his father had with disdain, he couldn't believe they dared to do that in a place where his innocent younger siblings might see what they were doing. Hadrian's gaze made all of his father's wives and concubines break out in cold sweat, they knew that Hadrian would not hesitate to end their lives if he wanted to, they also knew that the only reason Hadrian had not done so was that they were the mother of his half-brothers whom Hadrian sincerely loved.

He couldn't help but admire his cousin, he had never seen anyone who could match his cousin's talent and intelligence.

Potter's Castle

Shindou Potter was panting heavily, his body was sweating, the sleeveless shirt he was wearing was clinging to his body showing how sticky his body was. Shindou has white skin, a slender and muscular body, his face is handsome because that is the hallmark of the Potter family who is always born with a handsome or beautiful appearance. In contrast to Hadrian and Izuku who are more academically oriented, Shindou has achievements that lead to artistic talent and sports. He has collected many trophies and certificates that he got from the arts and sports competitions that he participated in.

He admits that he is not as smart as his cousins Izuku and Hadrian, his Quirk is not as strong as his cousins' Quirk, but he wants to be a hero who can walk side by side with his cousins. His mother had given up on herself, leaving her alone with only her father for another man. He didn't know why his mother would choose to betray her father who was a Potter for another man whose wealth was not close to Potter's. It was only when he was 13 years old that he understood that his father did not fulfill his mother's sexual needs due to his busy schedule. But, according to him, it can't be used as an excuse for cheating and ignoring his obligations as a wife and also a mother.

Shindou is a Vibration Quirk user, initially, he could only use his Quirk on earth, but thanks to Hadrian and Izuku's support he was finally able to vibrate air and water. The maximum vibration that he can produce at this time is only 8.8 Hz, but according to Hadrian, it is more than enough because it can create a tsunami that is quite large because of the strong vibrations that it can produce. Shindo is not only able to create vibrations, but he can also control sound, the Potter family is indeed famous for its Quirks, only a few Potters are born with weak Quirks and even fewer Potters are born as Quirkless.
