This is the list of characters appearing in the Onegai My Melody anime series.
Born on November 19, Uta becomes My Melody's first human friend. She is the first person to fall victim to Kuromi's Melody Key. She has an older sister called Kanade who is a beautiful and popular student in senior high school and a younger sister Koto, who is a very happy girl. Uta is also very cheerful and energetic; and well known for her honey brown curled pigtails and big hazel eyes. She has a crush on Keichii. When she sings she can power up the Melody Tact by singing, just like how Jun and Keichii power up the Melody Key. In episode 4 of the first series, it is mentioned that her mother is a "Star in the Heavens", meaning she passes away long before the events of the series take place. In Onegai My Melody Sukkiri, she became Kogure's girlfriend. 3 Years later after Sukkiri, she is reunited with My Melody in the High School Arc to stop the Dokurobou. She has also been seen in Kirara★ in the last episode.
One of Uta's friends and Flat's human best friend. Kakeru has known her since they were little. He has a crush on Uta. He had bullied Uta when they were young and now regrets it, hoping the past will be put aside as he attempts to tell her how he feels. He confessed his love to Uta in Onegai My Melody Kurukuru Shuffle. His first kiss was accidentally taken by Keichii, his second by Jun, and his third by Baku. In Onegai My Melody Sukkiri, he became Uta's boyfriend. He has brown hair and eyes.
Uta's hard-working father who works as a travelogue writer. Whenever he approaches a room in the house, especially the kitchen, Uta would try to hide My Melody away and pretend that My Melo was a stuffed animal. He once trembled when he saw My Melody serving him coffee in front. Kuromi one time cast a spell on him, making Masahiko's time faster than normal Earth time. He at last befriended My Melody when her brother and grandfather freed him from the spell. He loves making jokes and puns, much to his daughters' dismay. He also dreams of eternal laughter in his house. When he discovers that Uta and Kogure were dating in Sukkiri, he is at first furious, but then accepts it.
A famous violinist and teen heartthrob, Keichii's violin playing supplies Kuromi's Melody Key with Dark Power in the first series being the apparent chosen of the Melody Bow. Though very popular around girls he is often secretly agitated or indifferent to ladies. He joins Kuromi's side to unleash the Dark Power seemingly out of boredom but soon is the de facto leader of Kuromi's group. He is not above subterfuge to further his goals and keep the knowledge he is working with My Melody's enemies a secret from the heroes though he interacts with them freely. In ~Kurukuru Shuffle!~, he transforms into Usamimi Kamen with My Melody's magic. Forced to become My Melo's super hero due to his actions in the first season, he absolutely hates becoming Usamimi Kamen, as he is often apathetic and unenergetic when My Melo summons him. He also has a butler called Sebastian.
