In a world where innate abilities dictate one's social standing, Shindo Kazuki was discarded as trash due to his bottom-tier skill. After a lifetime of misery and a lonely death in the slums, fate grants him a second chance. Kazuki awakens seventy years in the past, returning to his student days with a lethal secret: the complete mastery of 'Tuning,' a revolutionary magical research he spent his entire previous life perfecting. No longer the helpless victim, he now possesses the knowledge to dismantle the oppressive hierarchy of the elite academy. By weaponizing the very skill once mocked as useless, Kazuki begins a ruthless climb to the top, crushing those who once looked down on him. He is determined to rewrite his destiny and shatter a society that judges worth by birthright.
