* The ONA features a big selection of [[EarWorm catchy]] tracks of varying genres -- many of which are used as the EndingTheme of each episode. Standouts include "Purple My Ghost" by Drop's and "Body" by Lillies and Remains.

* "Ninja Shall Perish" plays throughout Ninja Slayer's climatic battle with Laomoto Khan, and it's nothing short of EPIC.

* "The Girl Awakens" acts as Koki Yamoto's theme, an upbeat but rocking track that fits her pretty well.

* "Swan Song Sung by a Faded Crow" begins with a melancholic piano & whistle combo, then shifts to a more triumphant guitar riff around the halfway mark while keeping an overall sense of sorrow. This is Silver Karasu's theme, powerfully conveying his lonely, desperate quest for redemption as he earns it in the final hours of his life.

* Laomoto Khan's presence is always accompanied by the dark, foreboding tune of "The Godfather of Soukaiya." It evokes that feeling of helplessness in the face of a nigh-unstoppable, oppressive force -- pretty much describing the man himself.
