Mixed Bathing Vol. 7
I was just checking out the web site where Nagaharu Hibihana posts "Mixed Bathing" and see via the gobbledygook generator (AKA Google Translate) that the part posted on 03 Jan is the very final part. In other words the author has brought the series to a conclusion with the seventh volume. Now how long it will be before it it actually published in Japan I have no idea, but I would not be surprised if it was sometime in the second half of the year. I will be watching Over-Lap's blog to see when they schedule it.
As for why I think it will be July or later, there are a number of things that have to happen. First the author has to put it in manuscript form to send it to the publisher. Then the publisher has to arrange for cover and internal illustrations. The publisher may also want some text changes. All of that will affect when it gets inserted into the publication schedule. (There may be other things as well. I have no experience in the commercial publiahing world, but I do have experience pulling together project reports and technical reports to submit to a customer as part of a contract.)
There is also a comment about the author's new series with a link to it. According to the gobbledygook generator the new series has the title "Kazoku Gakuen's Wind Knight Committee Shooting stars are cut in the shadows"; I expect that the actual title is something more comprehensible. And for those who are interested, here is the link to the new series: (https://ncode.syosetu.com/n0908gs/)
