According to the artist, she was planning to release a R18 Gloria x Marnie doujin for Comiket 102. However, after August 31, she hasn't returned to any of her social media accounts. For the time being, only sketches from her FANBOX and a low resolution image from her Twitter account (page 36) are the only evidence left for this planned book. Since her Skeb (https://skeb.jp/@pukupuku_tr) and Skima (https://skima.jp/profile?id=126584) accounts are still open/active, there's still hope she will come back someday.
