SoundYou can imagine my surprise when I found out that the opening theme was by one of my favorite bands in one of my favorite genres. The song is called “Guardian Angel,” by Juno Reactor, and is part of a relatively narrow but surprisingly popular subgenre of techno called psytrance. As luck would have it, this aggressive, grungy, and metallic song is a perfect fit for the anime, and does an excellent job of setting the mood for the rest of the show. The rest of the O. One exception, however, happens in the beginning of the final episode, where a loud, obnoxious and utterly distorted guitar “song” assaults the viewers for a full 5 minutes.
Overall, the songs fit pretty much seamlessly into the show (and are excellent to listen to)
The nature of the anime doesn’t give voice actors a whole lot of room for emotion; if you’re the leader of an oppressive crime syndicate, for example, you’re pretty much expected to have ice in your blood.
