The first single from the, then, upcoming album HIGH TO LOW ELECTRO. It was issued on CD and as a CD/DVD release. Both came with an obi and both editions had a different sleeve, although the differences are very minimal.

The version of たわいないトワイライト on this single was mixed slightly different when compared to the album version, i.e. some effects were sometimes used on the vocals which are not present in the final album mix.
