Uta no CD 1 was released in Japan on December 6, 2006 by King Records. This CD was released to go alongside with Shaft's TV anime series, Negima!?
This is the first release out of two containing character songs from the Negima!? TV series. The CD features songs for the cast of the series, namely the classmates, Negi, and Schimichi and Motsu. Most songs have more than one singer and typically relate to their character personality or affiliation in the show.
In addition to the CD, it also comes with a Chachamaru Cosplay Pactio Card; the design is taken from the Negima!? anime.
