Magic and powers are sealed! Train, level up, and win with your own body!
About
Worldview
A world where magic, special abilities, and superpowers are commonplace.
The setting is a co-ed, three-year meritocratic academy— 《Tenrei Practical High School》.
In this academy, all innate magic, special abilities, and superpowers are sealed without exception.
The philosophy upheld is:
"True strength is not the power you were born with, but the power you have forged yourself."
You cannot rely on abilities. It is an academy where you train, learn, compete, and win through your own strength.
⸻
Level and Growth
At enrollment, everyone starts from Lv 1.
However, just because everyone is Lv 1 doesn't mean their physical abilities are identical. Physical strength, martial arts techniques, and experience acquired before enrollment remain.
Level is a numerical value indicating growth after enrollment, centered on muscle strength but also including mental strength and intellect. There is no upper limit.
You grow through various experiences such as training, classes, exams, matches, actual combat, and overcoming hardships. Defeat also becomes experience, leading to the next stage of growth.
Note that victory or defeat is not determined by level alone. Reversals against higher-ranked opponents are entirely possible through technique, physique, tactics, compatibility, and experience.
In the story, the current level is displayed as:
【Current Lv: Number】
⸻
《The Covenant of Training》
All students enter into the 《Covenant of Training》 upon enrollment.
This covenant continues for life even after graduation, and anyone who commits an evil act to harm others with clear malice will become Lv 0.
Because of this, the mindset rooted in this academy is not insidious bullying or despicable sabotage, but rather:
"If you want to win, train head-on."
Official matches, training, agreed-upon mock battles, self-defense, and helping others are not included in evil acts.
⸻
School Atmosphere
Meritocratic. However, not toxic.
Rather—
It is an intensely hot-blooded, high-energy academy.
"If you're weak, train!" "If you lost, win next time!" "Surpass who you were yesterday!"
Rather than the strong oppressing the weak, it is considered good to compete, train, and grow together.
Effort, friendship, competition, and growth are emphasized, and evaluation standards are not divided by gender.
⸻
Ability Sealing and 《Healing Zones》
On school grounds, all supernatural powers such as magic, special abilities, superpowers, and physical enhancement via magic are completely sealed.
No matter how powerful the ability user, within the academy, they can only rely on body, technique, and experience.
However, the infirmary and medical wing are designated as 《Healing Zones》, where the use of abilities is permitted strictly for treatment purposes.
Recovery, detoxification, hemostasis, and body repair are possible, but use for attack, physical enhancement, or matches is prohibited.
⸻
《Sealing Barrier》
The entire academy is protected by a massive 《Sealing Barrier》 that serves both to seal abilities and provide external defense.
Every time a person who has made the "Covenant of Training" grows, a portion of that power is accumulated in the barrier.
Due to the growth accumulated by countless students since its founding, the current barrier is considered virtually indestructible by external attacks.
In other words—
The more the students train, the stronger the academy itself becomes.
⸻
School Life
Classes and events involve training muscle strength, endurance, reflexes, martial arts, and weaponry.
The content is diverse, including one-on-one matches, team battles, obstacle courses, long-distance marches, base captures, and teacher-surpassing exams.
There is a strength ranking within the school, but evaluation is a comprehensive assessment including exam grades, match results, techniques, and achievements, not just simple levels.
During off-campus field trips, the ability seal is lifted, and it is possible to use original magic and abilities.
By the time of graduation, students have grown into individuals who possess:
"A thoroughly forged body" + "Original supernatural abilities."
