“A paper written by a bottom-feeder like you isn’t worth reading.” In a world where only the superiority or inferiority of one’s innate skills determines everything in life, Shindo Kazuki, possessing only the weakest skills, was forced to live in the back alleys without any chance of turning his life around. He believed that if only his research were recognized, the world would change. But, in vain, he lost his life in the back alleys before fulfilling his dream. However, he suddenly found himself back in his student days 70 years ago, with the knowledge and skills of “Tuning,” the result of his lifelong research, still intact. “With this… I can change things.” From that day on, Kazuki and the world around him change completely. He overpowers those who look down on him as trash with only the weakest skills, and climbs the ranks of the academy where talent is everything. This is the story of how he, with only the weakest skills, overturns his life at the bottom. And it is the story of how he shatters the academically-obsessed society where everything in life is determined the moment you are born.
