Chapter 1

When is the sunlight the most glaring?

Of course, it's in the early morning!

With his arm blocking the bright rays of light filtering through the pleated blinds, the veins under his skin were clearly visible. However, no matter how much he blocked, a speck of light would still penetrate his eyelids, forming a scene that was both dark and shimmering in his optic nerve.

The tranquility of the room was broken in the next moment—

"Big Brother~!! It's time to get up and eat!~"

With a clear, sharp voice like an angry bird, the door to the room was opened, and a—

pale golden-haired beauty appeared at the door, standing with her hands on her hips. She looked like a noble princess from a fairy tale, with skin as white as fresh snow, eyes like emerald gems with a faint luster, and a mischievous smile that had nothing to do with elegance. She looked down at the boy on the bed with a leisurely gaze.

Then, her small body spun in the air, and her slender foot landed heavily on the boy's stomach—

"Oof!!"

In that instant, the boy's body arched, and he was instantly fully awake!

—

"Unbelievable! Suzune, can't you find a different way to wake me up? I'm going to die!"

The boy sat up as if nothing had happened, but of course, it wasn't that he was fine; he was just used to it!

Ever since he could remember, his cousin had always woken him up this way. The reason he slept for so long was because—

in his dreams, there was a figure he admired. Suzune's father told him that it was his father, who was sealed in a seven-colored crystal and couldn't come out. In his memory, he only knew his uncle, Kyouichi Seto, and his cousin, Suzune Seto, but had no recollection of his father or mother.

His uncle once had a sister, who seemed to be named—

Asuna Seto.

Was she his mother?

He had once asked his uncle, who said no, but that she was a person with a very close relationship to him.

His name was Arthur, but no one knew his real name. Neither his uncle nor Suzune knew, and the name Arthur was given to him by Suzune when she was reading a knight novel. His uncle didn't object, and thus his name was decided. A past not worth remembering!

(Sheep: Ah, I'm not serious about the first chapter having a place for a joke, laugh~)

"Big Brother! Today we're entering the Dimensional Tower, so you have to work hard. I'm counting on you for my future 'hug pillow'!~"

The girl named Suzune said, sticking out her tongue.

"But I have to see if I can earn the money first..."

Arthur put on his clothes and slippers and headed downstairs.

"Although I'm looking forward to it, I'm not yet fifteen. I really want to travel to those amazing dimensional worlds..."

Suzune looked expectantly at the tallest building in the city, the Academy City.

"Well, you'll have your day soon enough!"

Arthur ran downstairs, quickly washed up, and went into the kitchen—

to start cooking!

His uncle's company was busy, so he had always been responsible for making breakfast.

"Big Brother, I want an omelet today..."

Suzune lay on the table next to the kitchen, watching Arthur. Every day, watching her brother cook was one of her hobbies.

"Sure... then it will be an omelet (Western-style cheese omelet, also known as a rice omelet, where the rice is wrapped in eggs and topped with tomato sauce)..."

Arthur was very serious about cooking, cracking eggs, slicing onions, mushrooms, bell peppers, cilantro, and ham...

Living in this household, the only thing he thought he could do well was cooking and housework. He wanted to do something for the family that had taken care of him.

"..."

"Fresh cheese omelet..."

"I'm going to eat..."

Arthur and Suzune started eating the delicious breakfast, which stimulated their taste buds and appetite, and they ate quickly.

"I'm going out... the rest is up to you, Suzune. It's the first day at the Dimensional Academy, and I can't be late..."

Arthur looked at the clock on the wall, stuffed the breakfast into his mouth, and ran out.

"Ah...! Really, I have to wash the dishes again!"

Suzune pouted, displeased.

"..."

After leaving the house, Arthur quickly headed to one of the five top schools in Academy City, the Chou-Tenjou High School. This school was one of the best in the city for ability development.

Today was his first day of high school.

Although he wasn't a descendant of one of the seven royal families, he did have superhuman abilities, especially in terms of physical endurance (which was probably related to his little sister's morning training, the stomping wake-up method was really effective). He also had extensive knowledge and scored in the top ten on the written test.

In this world, every boy and girl who reached the age of fifteen had to enter a Dimensional Academy, which was different from ordinary schools. The purpose of these academies was to enter various dimensional worlds to fight and collect Dimensional Fragments.

Fifteen years ago, the seven kings who created the universe fell into a deep sleep due to a sudden event. After that, the entire universe began to collapse, and only Earth remained. If the seven kings did not awaken, Earth would also collapse. To prevent this, the world government began collecting Dimensional Fragments from the Dimensional Tower.

With enough Dimensional Fragments, Earth could continue to function, and the excess fragments could be used for the "Awakening of the Kings." As long as one of the seven kings was revived, the entire universe could be restored. Therefore, when entering the Dimensional Academy, students also chose which of the seven kings' armies they would join.

The first king to be revived would rule the world, and only one king was needed for the world to exist!

Thus, this was the "Great Chaos Era."

*

Arthur's home was located in the center of Academy City, where only prestigious families could live. After all, the Dimensional Tower and the headquarters of the seven kings' armies were in this city.

However, his family was not a prestigious one but an ordinary one. The reason they could live here was not because his uncle, Kyouichi Seto, was the president of a small game company, but because of a woman named Reika Shizuki, who had significant power and was the head of the logistics department of the Dimensional Tower.

This woman might be his uncle's friend, he had always guessed.

Chou-Tenjou High School was a co-ed school. Unlike Tokiwadai, which focused on comprehensive ability development, Chou-Tenjou considered students' special talents when accepting them. This was why Arthur joined this school; his physical test results were average, but his written test results were excellent.

Humans born on Earth and other life races would have a "King's Ability," which was divided into seven types:

Dragon, Witch, Demon, Elf, Nether, Sea, and Demon.

The seven King's Abilities determined future development directions, and each race had different potential.

For example, the Witch race had high physical defense, the Dragon race had high magical defense, the Demon race had high vitality, the Elf race had high speed, the Nether race had high mental strength, the Sea race had high water abilities, and the Demon race had high critical hit values.

Of course, these were just surface-level common knowledge.

The specific potential also depended on the individual, which led to the existence of the royal descendants. The royal descendants stood at the top of the pyramid of the seven races, inheriting the blood of the seven kings to varying degrees. They were the nobles of this world, with special privileges.

The school gates of Chou-Tenjou High School had automatic detection capabilities, as did the other top five schools.

"Beep..."

"Student ID: 15,007

ID: Arthur

Age: 15

King's Ability: Elf."

After the automatic detection of his personal information, Arthur entered the school. If the detection failed, he would be ejected by the school gate, which had a spatial barrier inscribed on it, preventing just anyone from entering.

The number 15 indicated that he was the 15th batch of students at Chou-Tenjou High School, and 007 indicated his ranking in the grade. Unlike ordinary schools, the numbers at high school academies represented their strength rankings.

The Elf race indicated that Arthur's talent was that of an Elf. Only the Dimensional Academy could detect the King's Ability, and this was the first time Arthur knew his King's Ability.

The moment he stepped through the gate, the campus he entered was not what it looked like from the outside but a long tunnel. Each grade could only enter their own level, preventing upperclassmen from fighting with underclassmen.

The school was different from ordinary streets; students' abilities could only be used in the Dimensional Tower and the school.

In other words, even if they had magical abilities, they could not use them in the city, only in the school, the Dimensional Tower, and other special areas.

"Ah, am I the last one? Sorry, I'm late..."

When Arthur entered the A-level special class, he found that all the students were already there, with only the seat number 007 empty.

Sitting shyly in his designated seat, Arthur waited with the other students for the teacher to arrive.

However, it wasn't until the morning classes were almost over that a woman who looked very scary walked in.

Her eyes, which made one's hair stand on end, were half-open, and she seemed to be in a state of darkness. She had a severe smell of decay!

Her pale complexion made her look like a zombie.

"Hello, I am Itsuwa Toshin. I will be your mentor for the next three years, but whether you can complete the three years is unknown. My previous class was wiped out in the Dimensional Tower after one month!

Before we start the course, you must sign this—

Dimensional Chaos Agreement.

Your life and death are under my control!

Of course, you can refuse to sign and transfer to another class. My course is the most difficult and dangerous, but it also has the highest rewards. Normally, it takes at least six months for a first-year student to obtain a Dimensional Fragment, but if you pass my test, you can get one in a month at most.

No one has taken more than a month, because those who did all died!"
