This story has fine animation, video editing and sound editing. The original novels are lengthy, but the script writers have done a good job of condensing the story. The Chibi style inner thoughts add humor. The after-credits shorts are a hoot! The English voice actors are well known and quite good. You will recognize voices from series like Re:Zero and SAO. The story is family appropriate. If you don't like books, you may not feel the same excitement that book-lovers will find here. The author has done extensive research into the history of paper and printing and this series is genuinely educational.
The premise is the soul of a girl from modern Japan is reborn in the body of a dying little girl. The new girl is still sickly and could die at any moment. She has some memories of both lives, and she begins pushing her modern ideas onto those around her. She is constantly experimenting and creating inventions in a medieval world. She desperately wants books, so she invents paper, tools, ink, and printing technology. She also promotes cleanliness, new fashions, shampoo, and new cooking methods. In her old life in Japan, she was an isolated, self-involved book-lover. Now she is desperate to accomplish things before her soon expected death and her accomplishments far exceed her view of herself.
The story chronicles her rise from poor commoner toward greatness. She faces many challenges and dangers. Will she die of fever, will the nobles kill or kidnap her, will the rulers label her dangerous and execute her?
Season 3 should have been the most powerful season thus far, but the abbreviated season of only 10 episodes does not give the story the time it needs. Even so, you will be rewarded by an excellent season finale. If you want more, read the books by Miya Kazuki. English translations of fine quality are available for the first 20+ novels. Manga are also available. The initial web novels are available online in Japanese.
