Manga Adaptation of Juon: Owari no Hajimari and Ju-on: The Final

I'm honestly not sure if anyone here will have any ideas about this, but given that there's not really a Ju-On/the Grudge community around, it might be worth a shot.

I'm trying to track down this manga that supposedly came out in June of 2015. I can find no information about it save a single article by Crunchyroll. It would have been written by Eiko Komuro and published by Shogakukan. A Google image search just leads me back to the same article. Looking into Eiko Komuro, I still haven't found much of anything about this manga, save that it may exist? I'm not even sure I have a title for it (in theory it's called Ju-On: The Final, but I can't actually confirm this anywhere).

Any thoughts? Anyone hear about this?
