Well, the raws are out there. It's a 20-page story. Attached are pages with more robots and the character names and... ages? I don't know if it's more or less creepy that they come right out and go "yes, these female characters are of legal age". Like, if Sailor Moon can have an official blood-type...? I dunno.
(On the other hand, there is also a bath scene. So.)
The last page also contains the date for the next issue of Young GanGan, which suggests there might be a second chapter.
