＜Paperback edition released on November 5, 2022!＞

In 1901 (Meiji 34), Yoko Takatsukasa, the youngest daughter of the Takatsukasa family, one of the Five Regent Houses, invents a method to synthesize white thread from a chemical solution at the tender age of four. This thread is made of a substance historically known as "Nylon 66," which was meant to be discovered in America. And there's a good reason for that: Yoko Takatsukasa is a polymer chemist from the Reiwa era, more than 120 years in the future, reincarnated with her memories intact.

This is the story of a polymer expert who, reincarnated into an era where the concept of polymers is completely unknown, struggles to change the course of Japanese history.
