The battle themes in this game are planned to be voiced with lyrics either written by the musicians or the director. It would be cool to have a vocalist who is playing into the themes of these characters completely straight, even if the song not so subtly implies something dark or negative about the character associated with them, preferably high or regular pitched but able to go deep for characters like Voyeurelle. 

If you can, can you please provide audio of you singing over one of the songs referenced above as inspiration for the musician?
