It's mostly fluffy SoL so far, but it does seem like there's going to be plot, possibly fairly serious as well.
It's somewhat saddening that there's been no sign of a third volume since June last year though.
Also, I found this somewhere, and people might like it:
@lingo said in Kita no Toride Nite // At the Northern Fort:
is it on hiatus?? 2 volume and no update since march 2016 , if so that's too bad it looks a good read really :/
It says 3 volumes at the link. Last release was November 2016 according to Amazon.
I can't find this book at Bookwalker. Is it available digitally? Doesn't seem so.
There are some other mascot type series out there with fuzzy (or slimy iguana like) characters, but not all of them are reincarnation.
