whoah thank you for the information
Not a problem! :D
Thanks for the info, even though your comment is from more than a year ago have you heard of any updates
not OP but ch 7 came out in OPERA vol 79 which was released march 30th this year

According to this tweet from Syundei, the 6th chapter for this sequel came out in the magazine OPERA in 2018. I didn't see anything about it being the last chapter but in OPERA I couldn't find this in any further issues than 63 (on the link in the next paragraph. This is strange because this tweet says chapter 6 comes out in vol. 70).

However I could only find it being published in the magazine (meaning no tankoubon or ebook for this series only could be found). I'm not very informed about how the sales of magazines work, but usually you cannot buy old issues (they may be available but usually I can't find them) (Maybe you can buy it here https://comic.k-manga.jp/search/detail)
Here is the twitter for OPERA @OPERA_edt in case you want to keep up with the latest works. As of their most recent issue released in May 2020, none of Syundei's works are there (so they were either dropped between 2018 and 2020 or finished. You can look through the tweets if you want).
I also tried to search the link on the credit page of the chapter uploaded on this website to see if the people were still working on the series but nothing showed up when I searched the link so I don't know what happened to them.
If someone wants to try and purchase the magazine or already owns the magazines and wants to upload them that's your only hope of getting updates. Or you can do your own further research to see if there are people who have already worked on it elsewhere.
