Shindou Sefiria no Gekokujou Program

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. She died and got isekai’d, watch her in this cute adventure where she does her best to master magic. 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 fifteen, 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?
