The soundtrack's quite nice, being a combination of majestic, militaristic songs for the Kan-musume, then switching to a more ominous feel for the Abyssal's motifs, and making use of strings to really bring out the right mood for the more emotional pieces.

The soundtrack is so good that, truth be told, some of the pieces on the soundtrack could be used in a far more serious film, and they'd still work
