Someday in deed I did some more digging and found that Akagi Asahito's first Wani TankobÅn does not contain the chapter, so we are gonna have to wait for an eventual second Tank to release.
In a perfect world they would know, otherwise I can always hope to see them one day at a convention. (That is more selfish of me since I know you are in Germany, but one day I am sure you will attend a US convention)
With every Shindou release I get more, and more excited for an eventual full physical Shindou Box release. Anime Expo is just a few months away, and I hope they have physicals ready by then. Would also be a big plus if they could bring Shindou to the convention to meet the fans.
Koppori Nama Beer Sensei has been producing H-Manga for Comic Kairakuten for a year now, with a standard release cycle of every other month. That is amazing, congratulations to Sensei, and hopefully with 7 chapters and 143 pages already printed, a book may not be too far off in the future.
