In a world where only a fraction of humanity can wield mana, power decides everything. Nations are governed by Hero Associations, and only registered heroes stand between civilization and extinction. Rank defines status, wealth, and survival—yet even the strongest barely reach the highest tiers of S-Rank.

Tatsuga is an anomaly.

A quiet student living an ordinary life, he possesses abilities that shouldn’t exist—superhuman strength, flight, and a combat instinct that feels almost unnatural. Even more disturbing, he can reproduce techniques after seeing them just once. Despite this, he keeps his abilities carefully restrained, avoiding attention as he rises through the Hero Association’s system.

But something about him doesn’t register correctly.

During his official evaluation, the system begins to malfunction. Readings distort. Classifications fail. What should have been a simple ranking test turns into a situation the Association refuses to make public.

Special trials are arranged.

From combat simulations designed for elite heroes to classified environments meant to test the limits of humanity, Tatsuga is quietly observed at the highest levels. Every test produces the same result: he doesn’t fit within any known category.

And the more the world tries to understand him, the more unstable the system around him becomes.

Because something about Tatsuga shouldn’t exist within the rules of this world.

And the rules are starting to break.
