Aya Shachou and P/A - Same Artist?

I've thought this was so for quite some time, due to the very similar art styles used by aya shachou and p/a.

Just a short while ago, I uploaded post #693169. Not long thereafter, a variation (post #693243; apologies if the subject matter offends) was uploaded, parented to 693169.

Following the link to the pixiv page of 693243 shows it to be uploaded on P/A's profile.

I think a single minute is definitely insufficient for a user to have found the image, modified it, and then uploaded the new version.

Based on this, I think p/a probably ought to be aliased to aya shachou.

It would seem they're the same. There's also a Youmu dakimakura-type image on both, with the nude version on p/a.

Done.
