"Across the Warring States Period: Imagawa Continuing" is a Japanese Warring States time travel novel with Imagawa Yoshimoto as the protagonist. The timeline begins with the Hanakura Rebellion (1536). The author who loves the Imagawa family has wanted to write this book for a long time.
This work is a brand new independent story and protagonist. If you have not read the previous work, it will not affect your reading at all (just like each part of Jojo is independent). Of course, old book friends who have read the previous work can find some Easter eggs as a bonus!
