She quote retweeted this earlier this morning, It seems to be a trailer for a new video that will release in July (from what I can understand from the few comments and account digging). I don't think it'll be an explicit AV but I assume a softcore "gravure" version of the KATU Katsuo Butsusan/Mousozoku AVs that Maguro and Maglow makes due to the nature and bio of the account from which the tweet was posted. Here's the tweet and as well as the teaser put in a mirror in case you want to download it. (sorry if the format of this post is bad, i don't post often.)
