The Regressed Lowest-Ranked Wizard Overturns the Academy Hierarchy

"A paper written by a bottom-feeder like you isn't even worth reading." A world where the superiority or inferiority of innate skills determines everything in life. Kazuki Shindo, possessing only the weakest skill, fell into ruin with no chance of a turnaround and was forced to live in the back alleys. If only his research were recognized, the world would surely change. His hopes were in vain, and he lost his life in the back alleys halfway to his goal. However, when he came to, he had regressed 70 years back to his student days, retaining the knowledge and techniques of "Tuning"—the research achievement he staked his life on. "With this... I can change things." From that day forward, Kazuki and the world around him completely transform. Overpowering with true strength those who despise him as trash capable of only the weakest skill, he climbs the hierarchy of an academy where talent is everything. This is the story of someone with only the weakest skill overturning his rock-bottom life. And it is the story of him destroying an academic-centric society where everything in life is decided the moment one is born. (Source: Translated from LINE)
