The story is a suspenseful action drama in which three good friends, Momoko, Kijiko, and Wanko, the "Ribon Detective Club," encounter bizarre cases involving monsters and supernatural creatures such as ogres, sea beasts, kappa, and wolf boys, and solve them with their brilliant deductions and courageous actions. The fashion depicted by Suzuki Mitsuaki, including heart-shaped hats, mini-skirts, and ribbons adorning the chest, is timeless and modern, and the dignified, cute, and beautiful girl characters are still favored by many readers today.
