Gekokujyo Program by a Child Prodigy SefiriaShindou Sefiria no Gekokujou Program; The Prodigy Sefiria's Overpowering Program; План захвата власти одаренной Сефилии; 神童セフィリアの下剋上プログラム

Meet Sefiria. She may be just a baby now, but she holds a dangerous secret — she has memories of her previous life as a Japanese salarywoman. Anyway, yadda yadda yadda, she died, got isekai’d, bada bing bada boom. Now for the meat and potatoes of things. After experiencing the hell of living in such a rigid society like Japan beforehand, Sefiria wants to avoid making that same mistake in her second life. That’s when she remembered a famous saying back in her previous life: “At ten years old, you can be a prodigy. At fifteen years old, you can be a genius. At twenty years old, you’ll just be a normal person.” While the new world she was born in considers adulthood to start at the age of 15, Sefiria has a repository of knowledge from her old life to help back her up. Can she become a prodigy at an early age, revolutionize her world, and ensure herself a slow life that any Japanese reader would love to self-insert into?
