In a normal bedroom, a 17-year-old male with black hair slept on his bed with a blissful expression on his face.
Knocks started to echo throughout the room without notice, but the young man wore big noise-canceling headphones. With such big headphones, it would make sense that he wouldn't be able to hear it, or so it may seem.
"Nghh…" Strangely, the male could hear the knock clearly, waking up because of it. He rubbed his sleepy eyes before getting up from the bed and replying, "Yes, I'm aw-"
Before he could finish his words, the door was opened. He saw the familiar figure that had always been waking him up every morning. She had long black hair that reached her waist, big black eyes, a small nose, as well as a pair of tantalizing lips. She wore a white shirt under a white suit, as well as a blue tie and a white miniskirt.
Those clothes made her charm more enchanting, accentuating her beautiful proportion even further. She could cook and even do house chores. That's right. She would be a perfect girl, if only she wasn't such a…
"Kai!" She threw herself towards him. He had gotten used to this, so he avoided her and let her crash into his bed.
He avoided her, but it didn't make her feel disappointed. Instead, she grabbed his pillow as she smiled. "Fufu, Kai's scent. Today, Kai will go to school with me… Ah, this is the best day ever."
Kai glanced at her before increasing his distance from her. That's right, she was indeed happy, but then she realized another matter, making her mood turn for the worse. She said with a dark tone, "That's right, what if Kai gets a girlfriend in school? Damn you, government. I should change this policy when I become one of the high-ranking people. Or should I..."
"No killing, please," Kai replied with an uninterested tone. He had gotten used to this side of her. Her name was Tasha Carter. She was his incurable bro-con sister… well, adopted sister. He and his parents were on vacation before they met her. She was abandoned after her parents died in an accident.
They decided to adopt her so that their son could have an older sister that could protect him. But because of a certain accident, she became like this.
Kai Carter shook his head helplessly at the thought. He glanced at the mark on her right hand. Everyone had a mark like this on their body. For him, he had an eighth-note symbol under his right ear. He looked at the lightning mark on her right hand.
At the end of the 21st century, a strange accident occurred on Earth.
The people on Earth suddenly felt their bodies becoming more energetic with every passing day. The government started researching the cause, and at that moment, they found a strange phenomenon.
A dog suddenly expanded in size, as if it was undergoing an evolution. It killed all the members of the research team, as well as the people around them. Unfortunately, it didn't stop there. Other animals also underwent their respective evolutions.
The situation became chaotic because animals throughout the globe started turning into beasts. In the present years, they were called 'Magical Beasts'. People who owned pets died on the first wave after their pets killed them.
The government tried to fight them, but it was obvious that killing those beasts would not be that easy. Numerous nations were ruined by these magical beasts. These beasts terrorized the entire Earth. Without any other choice left, the people around the world joined hands to fight them.
It was not-so-effective at first, so they could only retreat and create a superbase with allied countries. Three bases managed to survive this ordeal, with those bases being located in Japan, the US, and Europe. With Japan's strategic location, which was surrounded by water, the terrestrial magical beasts from afar couldn't harm them.
They managed to kill the magical beast through their territories. The people around them were also migrating to the country. Japan finally became a country that hosted various nationalities. China, Russia, and even those from Indonesia lived in this country. And so, Japan changed its name to United Asia.
Such was also the case for the US and European bases. Each of them also took in various nationalities into them. People who managed to survive this ordeal used these three bases as places for recuperation and started to slowly turn the tides against those magical beasts.
Until all of a sudden, they found that their children had something that they called a birthmark. It appeared on every child around the world. Strangely enough, they found out that their birthmarks could glow, and that the children could use strange powers.
Children with a fire mark on them could control or summon fire. It was the same for children with a water or wave-like mark on them. They could control or summon water. The people called these children 'Magicians'. His sister had a lightning mark, which made her a lightning magician. Well, she also had another power that made her famous.
With that, the people were finally able to fight back those magical beasts. The world continuously produced such children every time they birthed. It seemed that it was the same as the magical beast evolution. But in this case, it was their children.
After retaliating for more than two centuries, the situation had eventually stabilized. Unfortunately, because of this accident, the population on Earth was reduced to a meager 5% of its initial number. Even more so, after these fights, the number of males who participated in the front lines had been decreasing until finally, women started participating as well.
Even so, the damage was irreplaceable. The current population of males was only a third of the entire population. Yeah, the policy in her mouth was that a man could have multiple wives, AKA, their own harem. Some chose to have one, and some decided not to.
For this hardcore bro-con, it was a significant matter. Kai Carter didn't really care about it that much though. For him, he wanted to build his own relationship first before confirming their relationship. He didn't believe in such a thing as 'falling in love at first sight'.
He grasped his sister and threw her outside his room. He then closed the door so he could change his clothes. He soon grabbed his white uniform. It was the same white uniform as the one his sister wore, except that he had long white pants. He looked at the ID and grabbed it as well.
ID: 000004884395 (UNITED ASIA)
Name: Kai Carter
Education: Genesis Magic Academy First Year
That's right. He was living in the United Asia Base. Jobs related to magic were high-paying jobs in this world. Those who became a student at a Magical Academy would receive an honor unique to them. As for the ranks, in this world, there were seven ranks, from F to S.
They were classified based on ability and magical energy. Kai Carter was only your average guy. His ability and magical energy level weren't high, but they weren't low either. From other people's point of view, he was just an average guy with an average aptitude.
B-rank magicians were considered as special people while A-rank magicians were considered as Aces. As for people with S ranks, there were only a handful of people in the world who had that rank. It was a Special Rank only for those who fit the requirements for that, which included his sister.
After he changed his clothes, he opened the door and saw that his sister was still standing in front of his room this entire time.
"Kai, let's eat breakfast."
Kai nodded his head. Both of them went downstairs and saw their parents. Their father was sitting while reading news on his gadget. The gadget was a kind of smartphone, but it was a bit more technologically advanced. They lived in the 24th century, but due to the onslaught of the magical beasts, technology didn't progress that much.
His father was a middle-aged man with very short black hair. His personality was not strict. In fact, he was a fun father to have. Kai looked at their mother, who was preparing their breakfast. Even though she was considered a middle-aged woman, her beauty was still preserved. Maybe because of their magical energy, their aging process had slowed down.
He recalled that most women in this world were the same, but it was different for males. It seemed they didn't care that much about their appearance, especially for those who were married. That's why their father had the appearance of a man in their mid-thirties while their mother looked like she was in her prime, which was her early twenties.
"Oh, Kai. That's right. It's your first day attending high school. Well, have fun. I'm sure your sister will protect you."
"Yes! I will protect him. Especially from v*xens!" Tasha said with a guts pose.
"Yeah, yeah, I'll leave him to you. Just watch your words." Their father, James Carter, didn't really care since he had gotten used to this. In fact, the whole family had gotten used to her personality.
"Fufufu. Well, I don't really mind having a few more daughters-in-law, though." Their mother, Ayaka Carter, said while giggling as she put the dishes on the table. Their mother was a local Japanese. Their great grandfather was a tourist in Indonesia. He was an English man, but, because of that accident, he fled to United Asia and settled down.
"Mom! How can you say that? They just want to take advantage of Kai!" Tasha protested.
Kai only kept his silence, not bothering to correct them. He just let it be and watched them to see what would happen.
"Uh-huh. Whatever you say. I will be the one to judge them, not you." Their mother stated it like it was her authority, not Tasha's. But then again, she was using her joking tone.
After living together for two centuries, their cultures had mixed.
They ate their breakfast while joking with one other. After finishing their breakfast, it was time for Tasha and Kai to go to school.
They were reaching for their shoes when Tasha suddenly realized that something was off. Kai's tie was a bit crooked. Her eyes immediately flashed with a glint.
"Kai, your tie is crooked. Let me fix it for you." She moved closer towards Kai.
Seeing her come towards him, he immediately fixed his tie casually. "Yeah, you're right. Thanks, Sis."
She froze after seeing him fix his tie. "Kai, it's the time where I should be fixing your tie, you know. You should let me fix it for you. Are you even a man?"
"Yes." Kai simply nodded, ignoring all her words.
She pouted in response. After that, they put on their shoes. Tasha shouted soon after, "Mom, Dad, we're heading out."
"Yeah, have fun."
"Kai, don't forget to bring a daughter-in-law!"
"No! He won't!"
And with that, the two of them finally left the house.
