I've sent in two change requests, but it doesn't appear to be going anywhere with that route so I'll post it here:

The last three chapters of Isuca are misnumbered on the release page. The release on 2/8 by Sacred Blade Scans was actually a special chapter, and is listed as 34.5 on their website. The release on 2/16 is actually chapter 35 according to their site (and Batoto). Up until yesterday afternoon, these listing were correct on the release page, and then at some point this was changed to chapters 35 and 36 respectively.

Now there's a new release today (2/17), which the scanlators and Batoto have listed as chapter 36, but the release page has as chapter 37, once again being out of sync with the scanlators.

As I said, I've sent in several change requests to get this corrected, but with no response from this site, so I hope that this is fixed, or at least we're given a reason for the discrepancy.

Yes, I changed the chapter numbering of Isuca to be in line with the actual chapter count of the author/tankoubon.

Chapter 34.5 is actually chapter 35, as indicated by the kanji in the release, however Sacred Blade Scans chose to change that as they did not regard 9 pages worthy of being a full chapter, hence the 34.5 and the subsequent deviation from MU chapter count and scanlator/Batoto count.

Well, that's going to cause some confusion.

So the scanlators and online sites (such as Batoto) have one numbering scheme, yet on Manga Updates they are using a different numbering. While you may be technically correct, it still will confuse people when they go to look up the latest chapter.

Maybe MU should do dual numbering for the chapters, like they often use for series like Nana to Kaoru to try to alleviate this.

The dual numbering for Nana to Kaoru is due to the restart of the series in another magazine though, thus it still complies with the magazine chapter count.

But I see where you are going with this. A solution as seen in Arifureta Shokugyou de Sekai Saikyou (Novel) (dual number + note in description) could be feasible to avoid further confusion.
Let's see if we can get some admin opinions...

(ㆁωㆁ*)

Yeah, that solution would probably work fine as well. As you said, hopefully an admin will chime in on this so we can settle the matter.

It's a shame that the scanlators just didn't number the chapters correctly, but there it is.

GhostWriter represents the MU staff in this matter as he is a Release Moderator

If that's the case, then GhostWriter can you make the changes you suggested?

I can't 😀

But I'll arrange for it to be done.

(ㆁωㆁ*)

That would be awesome, thanks! 🙂

It's been done. If the scanlator ever corrects their number, we'll get rid of the old numbering

Thanks for all the help, guys!

As the Bangaihen chapter of volume 6 was upgraded to to a regular chapter by Sacred Blade Scans, we are now - starting with c39 - in line with official numbering again. Hopefully it stays this way. 🤨

(ㆁωㆁ*)

LOL, what a cluster!

Anyway, considering the scan group plays fast and loose with the numbering, I wouldn't be surprised to see this issue pop up again! 😉
