Not family friendly at all.
In the nitty, gritty world of Santa Destroy, the chaos and unpredictability of everything makes nothing certain in the future. No More Heroes is a game that takes this to heart by turning the music on its head and surrounding the entire story in leitmotifs. While each track defines the character it represents, laying them in order will not tell you a thing about the story at all. With the multitude of different styles incorporated into the game, the world is ill-defined with no means of properly calling it any style at all. From the beginning to the gore filled end, the only thing we know is that the game lives in the moment.
