Soo...is there news about the reason or duration of this hiatus? I really miss this story.
The Manga is probably going to come back within the next 2 months (Maximum levels of copium).
On a more serious note, Yuusha Shoukan's manga was voted Best For Beginners on MAL. Therefore, with the new attention to the series, a continuation of the manga seems far more likely, especially considering that Shinkigensha, the publisher of YuuShou, will notice that there is an interest in the series' continuation. Thus, they may consider continuing it. The official monthly Comp Ace hasn't come out yet, as far as I know, and therefore, there's a slim chance.
