Ayayamu (あややム) appeared in the fourth movie, Hamtaro: The Mysterious Ogre's Picture Book Tower. She was writing the classic story of "Sunflower Taro" and had to finish it before 8:06, so she enlisted the Ham-Hams to help her act out the story.
Due to her past unsavory experience with friends who mocked her for her boastful attitude, Ayayamu has since closed herself inside the library and stopped believing in friendship, until after Hamtaro helped her to come out of her shell and allow him and his friends to visit her tower at any time.
