This is the bonus DVD that came with the ["Ultra Q Club"](https://ja.wikipedia.org/wiki/%E3%82%A6%E3%83%AB%E3%83%88%E3%83%A9Q%E5%80%B6%E6%A5%BD%E9%83%A8) Complete Box set, comprising interviews with the cast and crew of the radio show. I have also scanned the pamphlet that came with the DVD since it list credits for each of the episodes of the show. You can find the audio drama itself [here](https://nyaa.iss.one/view/1914958).
