The Highschool of the Dead hiatus will not end next month; however, there does appear to be something coming next month.
First of all, the official announcement for Triage X Volume 6 and for HOTD Full Color Editions 5 and 6 appeared in this month's Triage X chapter. TX Volume 6 will be out next month. There does not seem to be a specific date, though I would assume it is the 9th since they almost always come out on the same day as the magazine. The new FCEs are also apparently out next month. There is no date, but after some investigation on Amazon, I found that they will be released February 9. It seems strange that there wasn't more of a buildup.
Now, to elaborate on my cryptic opening sentence, there was a small announcement on the preview of next month's issue. I will include an image here and a full scan of the two-page spread with this month's Triage X raw. The preview focuses on Triage X (meaning it will likely be on the cover), but there is this little corner dedicated to HOTD:
From what I can make of it, it seems there will be a HOTD booklet with next month's issue celebrating (or promoting) the new FCE volumes. I'm not sure if this means there will be a color chapter or just illustrations, but I'm guessing I will be scanning whatever it is. I will update this post when I have more information. I doubt it is a new chapter, but we will see.
There's not much more to say about this issue. Triage X has a shortened chapter this month, which is no surprise considering everything Shouji Sato has coming out next month. I'll have the raws for it and Maken-Ki! posted sometime today or tomorrow. See you soon.
