SEDO Sounder's music. It is passion. Grief. Sense of inferiority. A glimpse of light in a depressing world. A gaze that seems to have thrown everything away, but has not given up on anything. All of these have been boiled down, and made into a black "poison". If you listen to this piece, you'll be able to taste his world view in one bite. It includes the song "Shiritakunai", which won the jury prize "Kotoba Asobi Award" at the 16th MMD Cup. There are also several unreleased tracks that can only be heard in this album. Enjoy the melody of jet black and magenta that only SEDO Sounder can create.
