sound files
Here you will eventually find a collection of audio files featuring Yuzu-chan and Kusa, up to only the Character File Track are available to download from my driveway account. You can access them from the link below. If you have any other files I'd be happy to host them (yup, even clips from that movie - poor Kusa, I can't say this too often, what did they do to you?). The audio files are rmx format which should play with your realaudio player.
