A paper written by trash like you isn't even worth reading."

In a world where the strength of your innate skills determines your entire future. Born with the weakest skill of all, Shindo Kazuki, was driven into the slums, never given a single chance to change his fate. He believed that if his research were ever acknowledged, it could change the world. But his hopes never came to fruition, and he died in those back alleys before he could achieve anything.

But when he opened his eyes again, he had returned 70 years into the past, to his days as a student. He still possessed every bit of knowledge and every technique behind "Tuning"—the culmination of the research he had devoted his entire life to.

"With this... I can change everything."

From that moment on, both Kazuki and the world around him began to change completely. Revealing the true power he had hidden all along, Kazuki crushes elites who mocked him as worthless for possessing the weakest skill, rising through the ranks of an academy where talent reigns supreme.

This is the story of a boy born with the weakest skill as he rises from the very bottom… and ultimately shatters the elitist society that judges your worth from the moment you’re born.
