Laura Haruno is the human owner of the hamster Hamtaro and the central human character in the anime series. She is a young girl, approximately ten to eleven years old, with short brown hair and brown eyes, and she has a birthday on December 15. Laura lives with her mother Marian and her father Forrest in a suburban home. She is a cheerful, fun-loving child who approaches life with optimism, often ending her days by writing in her diary. Her affection for Hamtaro is strong and mutual; she cares for him attentively, and in turn, Hamtaro is deeply devoted to her. Laura's motivations often revolve around her everyday joys and challenges, including her school life, her friendships, and her crush on a boy named Travis. Her best friend is Kana, another human character who occasionally appears alongside her. Within the story, Laura serves as the primary human perspective and the link between the human world and the hamster adventures. Many episodes involve the hamsters noticing a problem Laura is facing and working behind the scenes to help her, though Laura herself is usually unaware of their activities. Over the course of the series, Laura shows gradual emotional growth in handling school situations, family interactions, and her feelings for Travis, though her core personality remains consistently warm and optimistic. She does not possess any supernatural or exceptional abilities; her notable traits are her kindness, her imaginative nature, and her strong bond with her pet, which drives much of the narrative.
