Daniel or now known as Yuuki Wakura pondering about his future considering that he had chosen a random world to seek a good change only to be dumped into a world where females dominate over men. The world he was in was called Mato Seihei No Slave and had read the manga a long time ago but died before it had a chance to be finished.
The reason as to why he knows the world is due to the fact that his name was the same as the protagonist meaning he had taken over his places.
It was not a problem and frankly makes this convenient since he recalls that his elder sister was brocon and likely ended part of his harem for he ever had one.
Fortunately as Viltrumite this won't be an issue since his physiology is different than a human and likely seperate himself from his parents. He was incredibly glad that he wanted something that would be instantly integrated upon birth and didn't need to wait for 5 years since as Viltrumite he matured faster than normal and the intellect of Luther was slowly adapting into his physiology.
Even though the downgraded version still gave him an incredible level of intellect, he planned on making several tools to help him grow and run his own business. Yuuki understands that he also gains Luther's cunningness in business and will greatly benefit him in building an enterprise.
For a couple of months of being born, he already started to crawl and walk as well talk where his parents labeled him a prodigy even though Yuuki doesn't take pride in it since what he recieve is cheat and didn't work to gain it.
Regardless, Yuuki didn't act like a normal child and his new family was quite gullible thinking it was a miracle. Within a span of a year, Yuuki had memories and learned every language along with attaining a body similar to a 3 year old.
He also learned more about the world and how society functions. Several decades ago, mysterious gates suddenly appeared around Tokyo leading to the demonic metropolis dubbed Mato, where the Shuuki, ferocious monsters that inhabit Mato, and the Peaches, fruit which grants women alone special abilities and enhancements, are located. It soon led to the formation of the Anti-Demon Corps in order to prevent the Shuuki from entering through the gates and killing innocent people.
The Anti-Demon Corps is split into units, numbered one through ten (excluding the unlucky fourth cause Japan). All units reside inside dorms built inside of Mato itself and are protected by a barrier, which keeps Shuuki from invading. These dorms are located at nine different sections of Mato where gates leading into the real world exist, including the central location.
'I wonder if I ate the fruit knowing that I'm not completely human and not from here will I gain an ability. There's no harm in trying' ( Yuuki)
He thought of himself reading more about the peaches. The Peaches are special and unique fruits, which are grown in Mato itself and became the main source for the Anti-Demon Corps to expand their members.
Once eaten, the eater attains unique powers and has been theorized to be based on the background and emotions meaning that even if two people ate a peach, then their powers wouldn't be the same if their temperaments are different. It has also been stated that women cannot eat more than one peach.
For some reason, unlike women, men don't receive unique powers or enhancements after eating a peach causing the balance in power between both genders to crumble leaving women as being superior. This soon led to the men being left as either menial workers or even servants to women; even in a high school setting, male students are forced to clean the schools before the girls arrived at school (most of which all arrived late without punishment).
This is also apparent, as men and women have separate train carts, whereas the former is packed full of people, while the latter isn't.
Although there are rare cases, if a woman eats a peach, the blessing granted to them can at times run rampant in their bodies, resulting in a mutation that turns them into something akin to the Shuuki, while also maintaining their human minds.
These women who're turned into humanoids are able to devour more than one peach casually with no after effects. A humanoid such as his sister in the future, Aoba Wakura, who has shown to be as strong or stronger than a Unit Chief.
'I wonder if I should let my sister become a humanoid shuuki…'
Yuuki is yet to feel attached to her but couldn't deny that she was growing on him since he had been quite doting. He decided to let it happen believing that it will be a better outcome since he will make sure to get her back. Having Luther intellect will do its job later.
He might be doing something akin to letting events play out exactly as in the past but this will greatly affect the future if he interferes and trusts that his sister will be safe.
Yuuki also concentrated on building his body focusing on his stamina and calisthenics since weight lifting ruined his normal growth. He noticed that his system has still had yet given all the potential of Viltrumite since he struggles in some parts of his training but makes it a lot better and fun.
His parents only saw that he was an energetic boy and let her be while his sister encouraged him to ensure he'll become big and strong.
Yuuki growth was certainly noticeable when he reached the age of 4 and had a body similar to a 10 year old where he had long wild hair and spiky teeth where he was reminded of Rokuro from twin star exorcists.
"How long are you going to lock yourself in there, brother!? Today is your birthday!"
A female was heard as she opened the door to see his brother working on something and decided to play a prank sneaking closer until she tickled Yuuki who pretended to be caught by surprise.
"Ahahaha Nee-san. Hahaha stop it!"
"No, that's for getting distracted! What are you doing anyway?"
Her sister Aoba looked at the paper where it had a complex schematic and couldn't understand any of it. She knows her brother was a genius who already had passed college level lessons. As a sister, she was worried that his brother might find it hard to fit in with other people and tried her best to help him.
"Oh, I was trying to research on making a limitless and safe way to harness energy. I call it the Arc reactor. Though, it's still a theory but I'm confident this will be great in the near future."
"Alright, as long as you're happy."
Aoba didn't question any further and told him to head down stairs where he followed to find his parents had begun celebrating his birthday where Yuuki smiled appreciating their effort viewing his parents as important people and noted that it was best if they didn't get involved with in the future.
He is unsure if they will end up dead like his last parent and decided to at least give them a chance. Though Yuuki decided to make them work overseas, giving him some free time and peace of mind, they'll be safe.
Though, he likes to fight and troublesome personality has his integrity repaying his parents to at least live. He finished the birthday party and headed to his room where it was finally time he gained what he needed.
'Open system' he thought to himself. The same screen he recalled from five years ago popped up in front of him, except it now showed that he had three deliveries in his inbox. Before Alex could open them though, the image of an angelic woman popped up in his system. He pondered why everything seemed similar to that story he had read a long time ago.
'Who the hell are you!?'
[ Good morning, and happy birthday. I'm your watcher, an angel if you will. I'm here to watch over you, and assist you while you grow. Everyone part of this game has one of us with them. My name is Ivory. ]
Yuuki noted her name and suddenly felt a burden upon his body being lifted and he soon found himself floating in the air. He smirked seeing himself fly and was grateful that he concentrated on training his center of gravity and acrobatics to allow him to easily control his flight.
'Great! I can finally utilize everything!'
He could feel his intellect skyrocketed, easily understand any subject and solved the missing parts of his Arc reactor. Yuuki decided to begin his plan for a company investment and also hacking information that will help him in the future.
'Right, can I ask you some questions?'
[ Depends on the question but I will do my best to answer all of them. ]
'Well, I'm not human and wonder if it will be possible for me to consume the peach and gain powers.'
[ I don't have the answer, however, I believe the result will be vastly different from a normal human male. ]
Yuuki nodded, finding the answer to be useful as she didn't say no rather was unsure and clearly knew that it would have different results.
'Alright, the next one is simple, can I inform my parents when I leave this world?'
[ It's up to you since either way it will not affect us. ]
Yuuki nodded and checked his status, satisfied what it displayed.
[ Name: Yuuki Wakura
Age: 4
Race: Viltrumite
Lvl: 0
[ Abilities ]
Garou's Martial Art Talent
Downgraded Lex Luther's intellect
Viltrumite Physiology ]
He decided to call it a day since he had a long day of training. Yuuki aims to replicate martial arts from One punch man and other series since he was obsessed with martial arts.
Yuuki is unable to perform them since they are too unrealistic to be replicated but now everything is different. Having the raw talent of Garou means he can easily master and learn martial arts.
He did memorize their background and how to use them, having a lot of techniques that he tried but was unable to use in the real world. Yuuki imagines himself mastering Water Stream Rock Smashing Fist, Whirlwind Iron Cutting Fist, Cross Fang Dragon Slayer Fist, Exploding Heart Release Fist and Roaring Aura Sky Ripping Fist.
If possible he can learn Divine Heavenly Destruction Technique and Gathering of Ten thousand shadows from Gosu and Return of the Northern blade.
==========
The next 4 years, Yuuki had been studying his newfound powers in the mountains when he had a chance since he did go to school not because of academic purposes but for social purposes since he was already better than his peers but his parents wanted to socialize.
He can still remember when he complained telling them his sister is enough making her incredibly happy but they didn't like him growing up alone and in the end he let it go.
Yuuki grew up as that near perfect student where he was smart and physically fit but did often act like a savage beast having beaten those who bully others even though he did it because he was annoyed at them and eventually became a star to his school.
As for his usage of his intellect, he had already gotten a multi-million dollar business called [ Star Nova Industry ] who distributes military technology and investment in the Anti demon corp under an alias having someone work for him that acts like the CEO.
No one would believe that an 8 year old had more money than the entire country of Japan since he is a worldwide company. He did this under 2 years while doing other stuff like training his martial art.
He tried to gain control over his rapidly increasing strength since unlike Invincible from the Invincible series was full blooded Viltrumite meaning he has the highest and purest genes of a Viltrumite.
Fortunately, Martial art helps in these areas and his parents tried making join a martial art tournament but were against it since he was literally fighting a bunch of inexperienced kids.
In his previous life, he mastered Muay Thai, Karate, kung fu, kenpo, Aikido, Kali, Systema but he doesn't like using guns and learned it for the sake of removing guns from opponents, CQC and among other things.
He was training in learning Whirlwind Iron Cutting Fist finding Garou martial art talent seemed to have given him muscle memories, slowly learning them and applying them into his martial arts, slowly developing the Monster Calamity God Slayer First.
Yuuki decided to concentrate on improving his hand to hand combat before trying his hands on swordsmanship if possible.
At the current moment, Yuuki stood half naked showing his physique that was incredibly ripped for his age having appearances of a 12 year old similar to Killua. He had long hair tied in a man bun and his pointy tail appeared like a tail.
"Alright time to gain experience…"
Yuuki panting and covered in sweat as he walked away from his spot where behind him was the side of a small mountain having been utterly devastated from his fist showing how terrifying his power was.
If anyone witnessed what he had accomplished then they would be dumbfounded to learn he was only 8 years old and had yet to reach maturity. The older a Viltrumite gets the stronger they become and less they age.
