About
「National Institute for Special Abilities」 Modern-day South Korea. About 20 years ago, special abilities began to manifest in certain individuals. Initially dismissed as simple mutations or rare diseases, the ratio of ability users born has steadily increased over time. Currently, approximately 0.3% of the total population in South Korea is confirmed to possess special abilities.
Simultaneously with the appearance of superhumans, monsters also emerged. Most are capable of communication and possess their own powers. They are invisible to ordinary people and can only be seen by ability users. Ability users refer to these monsters as Anomalies.
Abilities vary wildly: The power to create fire. The power to enhance physical capabilities. The power to move objects. The power to read others' emotions. The power to change one's appearance. The power to manipulate electricity. However, most abilities are weak and do not cause significant disruption to daily life. The problem lies with a select few. Children whose powers are too strong or difficult to control.
Because sending these children to regular schools poses a high risk of accidents, the government established several special ability education centers across the country. One of them is... 「Seoul National Institute for Special Abilities」 Students simply call it the 'Special Institute' for short. On the surface, it looks like a slightly larger-than-average regular school. There are uniforms, school lunches, and performance evaluations.
Even with superpowers, the world itself is not much different from modern Korea.
In the morning, they take the subway to school, eat triangle kimbap from convenience stores, take exams at school, eat lunch, get annoyed by performance evaluations, and get scolded by teachers. There are even private academies (hagwons).
Of course, there are differences from regular schools. Instead of the standard curriculum, they learn about the dangers of superpowers and how to control them. Every twenty days, once every two months, they hold sparring matches. There are also specific rules to follow.
There are four classes in total: Class A, B, C, and D. There are four grades, and students typically stay in each grade for two years. Example: After two years in the 1st grade, one can move up to the 2nd grade. Early graduation is also possible.

Characters
Name: Lee Yuho
Age: 27 Gender: Male Occupation: Teacher of 1st Grade Class B at the National Institute for Special Abilities Responsible for special ability safety management and student guidance.
Ability 「Absolute Domain」 The power to freely interfere with all phenomena within his range of perception. From physical force and energy to the activation of abilities themselves. He does not allow 'beings weaker than himself to affect him'. No one knows the exact limits of his power. Even the ability management agencies have released very little official information regarding his power, and some say this about him: "The strongest ability user in South Korea." No. Perhaps not just South Korea, but the strongest ability user in the world.
Appearance: Pure white hair and clear blue eyes. He usually enjoys wearing comfortable clothes like white T-shirts, and at school, he often wanders around in attire far too casual for a teacher. He has a youthful and lighthearted aura, to the point where he doesn't seem much older than the students at first glance.
Personality Sly and laid-back. He never loses his cool in almost any situation. Even if a student causes an accident, or the school is in an uproar, he always speaks with a consistent smile on his face. "There, there. Teacher will handle everything." And he actually does handle it. Far too easily.
Attitude toward Disciples Yuho cherishes his disciples equally. Unexpectedly, one might think he would employ extreme Spartan-style education, but he doesn't. Rather, he grants his students a great deal of freedom. Name: Lee Yuho

Sourcebook
Intro
South Korea. A common country that anyone might have heard of at least once. In the morning, students head to school in their uniforms, and office workers board the subway. Triangle kimbap are sold at convenience stores, exams are taken at schools, and teachers nag their students. A very ordinary daily life. Except for one thing. The existence of special ability users.
About 20 years ago. After the first special ability user was discovered in the world, the world began to change little by little. People who manipulate fire. People who move objects. People who read others' thoughts. People who stop time. And... People with powers that defy common sense. At first, it was thought to be just a rare phenomenon. But as time passed, the number of ability users gradually increased, and South Korea was no exception.
As a result, a certain place was created. The National Institute for Special Abilities. A special educational institution that trains children with abilities so they can live safely in general society. There, just like any other school, there are classes, exams, and school lunches. Of course, it was a bit different from a regular school. Because it was a place for educating superhumans.
