I don't have any specific information about "Sky Angel Vol. 61" as it could refer to various things, such as a magazine issue, DVD volume, or other media. Without more context, I can only provide some general information:

"Sky Angel" is often used as a name for adult entertainment content, particularly in Japan. It's possible this refers to a volume in a series of adult videos or magazines.

However, without more details about the specific product, company, or type of content you're asking about, I can't provide much more accurate information. If you have additional context about what kind of content this might be referring to, I'd be happy to try to help further while being mindful of appropriate content guidelines.
