My first time writing a one-shot book! A Tokyo revengers one-shot book in which the Haitani brothers have a younger sister. The majority of the characters in this book are owned by Ken Wakui. I only own Reiko and the parents of the Haitani siblings !! 💜 (Credits to the artist whose artwork was used in my book cover) Started: 04/21/25 Ended: ??/??/??
