Collaboration: Melocure 3d592j

Melocure was a Japanese pop duo consisting of Okazaki Ritsuko. They were signed to Columbia Music Entertainment. The duo's name is based on a pun on the term melodic hardcore.

Melocure formed in April 2002 and debuted with the song Itoshii Kakera (My Better Half), which was used as the anime series UFO Ultramaiden Valkyrie's opening theme song. More of Melocure's work was used as insert songs and themes for subsequent seasons of the show, as well as in the soundtracks of Stratos 4 and Okusama wa Mahou Shoujo. Melocure also had a weekly internet radio talk show. They released their album Melodic Hard Cure in March 2004. Less than two months later, Okazaki died suddenly at the age of 44 from septic shock as a result of septicemia. Melocure's final song, Home & Away, was finished by Hinata after Okazaki's death and released more than a year later.

Although Okazaki has died, Hinata has said on her radio show that she will continue Melocure for the rest of her life, singing Melocure songs at her live shows in Okazaki's memory.
