I don't have any specific information about "Sky Angel Vol. 79" as it could refer to various things, such as a manga volume, a music album, or another type of media. Without more context, I can only provide some general information:

1. If it's a manga: Sky Angel is a Japanese manga series written and illustrated by Toshihisa Kuboki. The series has multiple volumes, so this could be referring to the 79th volume in the series.

2. If it's a music album: There doesn't seem to be a widely known music album with this exact title.

3. If it's part of another series: It could potentially be related to other media that I'm not aware of.

To get accurate information about this specific volume or item, you would need to provide more context or specify the exact nature of what you're asking about (e.g., which series, format, etc.). If you have additional details, I'd be happy to try to help further.
