Checking on Pixiv, it seems that the artist simply stopped updating this comic. Kouji is still quite active, so it has to be something specifically having to do with the series, rather than the artist himself. I checked Pixiv, the artist's blog, and the comments on page 62 (the last one) on Danbooru, but I can't find any mention of hiatus or cancellation. Then again, I'm putting the Japanese through a translation filter, so I may be missing something or not looking in the right place. I've seen series resume after longer periods, so this isn't necessarily dead. Again, though, I'm not really sure, so someone more keen than myself may be able to find out more.
