Little Miss P by Ken Koyama is a young adult manga that follows the story of various women and their experiences with a period. The main message of this book is that periods are widely misunderstood, so this book guides you through some insight into what a woman's period is actually like. Little Miss P, the character representing a woman’s period is shown entering a girl's life throughout the book, whether it's a young teen who just started her period, a quick visit, or an elder woman experiencing her last menstruation, each story and character is unique. During each short story, the story presents itself as a new character along with its own set of problems, which represents realistic problems a woman might face during that time of the month. All while being humorous and silly. For example, Little Miss P is shown throughout the book giving girls “Period Punches” where Little Miss P dramatically gives a punch that would result in being thrown across the room. I rate this book a 5/5 because of the way the book humorously presents itself all while addressing the serious realities of having a period. I also liked how the book showed various perspectives and options on having a period. This book also showed other real-world problems outside of having a period, like having separated parents and other related issues. I recommend this book for teens who want to learn about periods and the life of a menstruator or for teens who just want something funny and relatable to read.
