Sengoku Era
In a world governed by Kizo—an energy that determines one’s status, wealth, and future—Yuki Kinatarou is a "Zero." Ranked as a mere Acolyte, the lowest of the Gamma Ranks, he is viewed as nothing more than a glitch in the system of the elite Kyorin High.
But Yuki has a secret. He wasn't raised in the world of royals; he was forged in a prison of his room, punching steel until his knuckles bled.
While the elite students rely on fire, wind, and lightning, Yuki relies on the "Law of Physics." When he enters the prestigious Class 2-A, he doesn't just break the rules—he breaks the sensors. With a sarcastic AI named Kira in his bag and the school’s "Paragon Queen," Seri Kyorin, watching his every move with a mysterious smile, Yuki begins his ascent.
The "Star Pupils" call him a charity case. The teachers call him a mystery. But as the shadows of his true lineage—the Kinatarou name—begin to resurface, the world will realize that the era of peace of is ending.
The Sengoku Era has begun.
