My Melody, the main protagonist of the series, is a rabbit from the forest of Mari Land. 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, "[object name] Onegai?" ("[object name] Please?"). This causes the enchanted object's power to intensify, sometimes increasing its size. 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 scatterbrained and oblivious to things though. She also doesn't seem to have any affections for 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 Takt, 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 Takt 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.
Kaji is in the same grade as Ayu and Nina, and is also the school idol. He is considered cool and always has a nice smile. All his fans are constantly giving him presents, and he even has admirers from the 3rd grade. However, this is only his outer mask. Kaji is in reality a normal guy who hates being given presents by people he doesn't know. But he is working hard on his "nice person" persona because the girl he likes, Ayu, once told him that's the way she liked him. He becomes closer to Nina after she discovers his deception. He is an introverted person, and doesn't like giving away his real feelings or thoughts. Kaji belongs to the school's baseball club. His best friend is Tsujiai.
Tsujiai is a classmate of Kaji, Ayu and Nina. He is the head of the male tennis club and is a slightly extravagant person. Ayu seems to hate him because at the start, he always managed to destroy her chances with Kaji one way or another. Tsujiai introduces Nina to Doraemon (which she loves). His best friend is Kaji and he likes Nina which is shown more in the manga than in the anime. He has a cat name Shinnosuke and is the third person to know that Nina was a magic girl because he saw that Rio the cat transforms into a human.
Jean Henri Fabre first appears in the beginning of the first episode, when he attempts to steal the "Immortal Beloved." He rides a giant mechanical grasshopper and can control bees and other insects to use as weapons. Like the insects he studied, juvenile Fabres are shown moulting from one form to another, growing from child to adult in a few days. Two Fabres are shown in the series; the first Fabre apparently dies by crashing into a Tokyo office building, but actually moulted and escaped, taking the form of a child until he fights and is killed by Drake Anderson within the I-Jin base.
Toboe is the youngest of the group often acting more like a puppy. Toboe was raised by an elderly woman as a pet. She gave Toboe his silver bracelets. Although she died, Toboe has an affection for humans that none of the other wolves can understand (with the exception of Blue). Toboe looks up to Tsume and usually follows him when the group splits up. He also seems to have the best hearing out of all of them. Toboe seems to be a Red wolf in the series. (Source: Wikipedia) Toboe's name means "Howling" in Japanese.
