My Melody (マイメロディ?)
* Seiyū: Rei Sakuma
My Melody, the main protagonist of the series. Is from the forest of Mari Land, and she is a rabbit. Throughout the show, she is shown wearing a pink hood that also covers her ears. With adequate cooking ability, My Melody is the one who prepares meals for Uta and her family. Her nickname is My Melo.
The magic that comes from her tact can only be used as an antidote to Kuromi’s spell. When she waves the tact, a small heart sticker attaches to an object and brings it to life. The animated object then helps to reverse the effects of Kuromi’s magic. Sometimes, the animated object won’t be able to perform the specific task it needs to. My Melo will then smile at it sweetly and say, “Onegai, [object name]?” (“Please, [object name]?”). This causes the enchanted object’s power to intensify. Surprisingly, even Kuromi has become one of the things Melody used her magic on which was seen in one episode.
As a very cheerful individual, My Melo is never seen angry. She can be a bit scatter-brained and oblivious to things though. She also doesn’t seem to have any affections on anybody the way Kuromi and Uta have for Keichi, although she is quite fond of Usamimi Kamen.
To travel from place to place, My Melo uses a pink umbrella which enables her to fly. This was until Kuromi stole and used it to go to Mari Land. Since then, she started sharing with Flat’s umbrella. She regains it back in the second season though.
She has two magical items. The first one is the Melody Tact, which she uses to cast magic by waving it like a maestro’s baton. In ~Kurukuru Shuffle!~, the Melody Tact was upgraded into the Hyper Melody Tact by the king, but in Sukkiri♪, it was destroyed in the final battle, making it useless, although it was repaired a short time later by the Melody Box. The second is the Heart and Star Pendant, which appeared in Onegai My Melody Kirara★, My Melody uses it to do magic along with Kirara.
* Seiyū: Kaori Miura
A blue mouse with a ribbon on his tail. He is the closest among My Melo’s animal friends. Whenever there’s trouble, especially a curse created by Kuromi’s magic, My Melo sometimes casts a spell on Flat to deal with it. There have also been hints that Flat may have a crush on My Melody, for example blushing when she hugs him in one episode.
Flat also has great social skills when it comes to interacting with the opposite gender. With these, he occasionally gives pointers to Kakeru when trying to contact Uta in certain situations.
* Seiyū: Junko Takeuchi
A bizarre replica of My Melody, Kuromi is her rival. She is also a rabbit and wears a black joker’s hat with a pink skull at the center of her forehead. The skull’s facial expression changes to match Kuromi’s mood. Wielding a magical artifact called the Melody Key, which is infused with dark dream-corrupting powers, Kuromi is trying to collect 100 Black Notes in order to resurrect the Spirit of Dark Power, in the hopes that it will destroy her enemies, especially My Melody. Her tail is a weak point wherein she would fall unconscious if someone were to step on it.
She is an escaped prisoner from Mari Land. It was later revealed that Kuromi committed crimes like stealing bread in order to feed Baku’s poor family. When Kuromi was on trial, Baku tried to convince the judge that he too was responsible. But Kuromi claimed that Baku was lying, so that her friend wouldn’t share a similar fate.
What started her grudge towards My Melo was an incident where My Melo unknowingly tore a page from her journal to wipe Piano the sheep’s nose. Since then, Kuromi has been writing down on it all the mishaps and unfavorable moments that My Melo has caused her (accidentally). More than 3,000 events written, Kuromi sometimes reads them in front of My Melo, but My Melo seems oblivious to why Kuromi’s so upset over them.
Kuromi is the leader of a biker gang known as “Kuromi’s 5.” Other members include a purple cat named Nyanmi, a pale orange dog named Wanmi, a white fox named Konmi, and a grey and white rat named Chumi. They all wear black and drive around in a menacing fashion.
Just like Uta, Kuromi has affections for Hiiragi. Her affections for him seem somewhat stronger than Uta’s however. In one episode, Kuromi used the power of the Melody Key to turn herself into a human being so she could dance with him, taking the pseudonym Kurumi Nui. Hiiragi actually seemed to be very attracted to Kurumi Nui, but, unfortunately, the spell had a Cinderella-esque effect: if Kuromi did not return to the spellcasting circle before all the magical candles blew out, she’d be turned into a tapir like Baku. Because of this, she had to run away in the middle of dancing with Hiiragi, but he kissed her hand in farewell. In the show’s opening theme prior to this episode, Kuromi is seen in the rain under a blue umbrella (Uta is usually in this part).
Besides being desperate, Kuromi also has a bit of a good side. On Christmas Eve, she first refused to accept the gift her parent’s gave because she was still displeased on why nobody, not even them, came to visit when she was imprisoned. But with it include a letter telling that her parents still cherished her and that they even tried to come inside the dungeon but weren’t permitted. Deeply touched by this, Kuromi accepted the present. She then returned to Uta whom she ignored to help earlier. Combined with My Melo’s magic with some from Santa Claus, Kuromi helped summoned the spirit of Uta’s deceased mother (how this person died isn’t known).
* Seiyū: Noboru Maeda
A purple tapir and Kuromi’s sidekick with the ability to fly. He, in some episodes, appears to have a crush on Kuromi, and is often victim to Kuromi’s anger. Kuromi is frequently very physically abusive to him, but regardless, she truly does love him, although despite the fact that they’re both animals, they have a master-pet relationship.
Like Kuromi, Baku has a journal where he writes down his moments with her. Hiiragi burns it in the middle of the first season, but he somehow retrieves it in the second season when they break out of jaio.
His birthday is confirmed to be on February 29. His name is a bit of a pun: in Japanese, baku could mean a tapir or a dream-eating creature of Japanese mythology. In one episode he has a crush on Uta. He does appear to have a conscience. On one occasion, he was seen delivering newspapers and giving rides to children. Baku has the ability to sniff out Black Notes, and whenever a new one is obtained, Kuromi skewers it with a magical stick and Baku eats it for safekeeping. Baku first met Kuromi at a beach in Mari Land. Baku usually says “Zona” at the end of his sentences, a lot like a catchphrase which is common of anime characters.
Uta Yumeno (夢野 歌?)
* Seiyū: Azusa Kataoka
My Melody’s human friend. She is the first person to fall victim to Kuromi’s Melody Key. She is very cheerful and energetic. Also has a crush on Hiiragi. When she sings she can power up the Melody Tact by singing, just like how Jun and Hiiragi power up the Melody Key. We discover in Episode 4 of the first series, 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 girl friend.
She appears in the last episode of Onegai My Melody Kirara★ in a cameo appearance along with old cast.
Kakeru Kogure (小暮 駆?)
* Seiyū: Miyuki Sawashiro
One of Uta’s friends. 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 kisses were accidentally taken by Hiiragi, his 2nd by Jun, and other by Baku. In Onegai My Melody Sukkiri, he became Uta’s boyfriend.
* Seiyū: Hiroshi Shimizu
Uta’s hard-working father. Whenever he approaches a room in the house, especially the kitchen, Uta would try to hide My Melody away. He once trembled when he saw My Melody serving him coffee in front. Kuromi one time cast a spell on him, making Masahiko the fastest man on earth. 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. When he discovers that Uta and Kogure were dating in Sukkiri, he is at first furious, but then accepts it.
Keiichi Hiiragi (柊 恵一?)
* Seiyū: Ryōtarō Okiayu
A famous violinst and teen heartthrob, Hiiragi supplies Kuromi’s Melody Key with Dark Power in the first series. Very popular around girls. 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.
