What is this I don't even...
When you know the original song (Servant of evil from the vocaloid Kagamine Len, as sated in the opening), this suddenly creates a huge dissonance in conflict with the original story of the song. Simply because it is based on a horrendous translation (even though an effort was actually made to translate the song, either that, or an actual translation was purposely made to be corrupted) of the song, and thus thoroughly corrupted. The translation is severely wrong, and if anyone's looking for a proper translation and the actual story, go search youtube.
For those who have no idea about the song, you might find this somewhat interesting, though random, but it's nothing properly good.
Anyway, the graphics could be drawn better, and overall, it simply looks like some sort of slipshot work made in a few hours.
