Kuromi (クロミ Kuromi?) is the rival of My Melody from the anime Onegai My Melody. She is a white rabbit or imp-like creature, wearing a black jester's hat with a pink skull on the front and a black "devil" tail in the place of a normal rabbit's tail. Kuromi's appearance also looks similar to that of classic cartoon characters from the 1920s and 1930s. Goods featuring Kuromi first appeared in Japan in 2005. She has three image songs all sung by her voice actress, Junko Takeuchi. Kuromi sometimes wears fuchsia pink skull cherries on her right ear.
Kuromi's birthday is October 31 (Halloween). Although Kuromi has a rowdy free spirit, she is actually quite girly on the inside and has a soft spot for cute and handsome guys. Kuromi enjoys keeping a diary and reading romance novels. Her favorite color is black and her favorite food is shallots.
