At Advanced Nurturing High School, strength isn’t just about grades—it’s about survival. Beneath the academic façade lies a hidden battlefield: the Kengan Arena, where corporations, elites, and shadowy factions settle disputes through blood-soaked combat.

Kure Ragna, a first-year student in Class D, is no ordinary fighter. A direct descendant of the feared Kure Clan, he was raised to dominate the battlefield with overwhelming strength. But here, raw power means nothing without strategy. In a school ruled by manipulation, deception, and psychological warfare, Ragna must navigate a game where one wrong move could mean total defeat—both in the classroom and in the ring.

Yet something is off. The school’s ranking system is more than it seems, and unseen forces are watching his every step. As rival fighters emerge from the shadows and the true purpose of the academy comes to light, Ragna faces a brutal truth:

The Perfect Human of today vs. The Strongest Assassin in history.

To survive, he must outthink the masterminds and overpower the monsters.

Because in this world, intelligence is power—but strength is absolute.
