There is, it is just slow paced. Well, has relaxed pace I would rather say. The Light novel is already 11 volumes and ongoing. I personally really like the relaxed pace. I can see why it don't fit for everyone, but it does indeed have a plot, pretty serious one, but I don't believe the lighthearted tone of the story ever goes too dark.
It hints at lot of very real dark stuff (like with the undeads in the town and their actual origins), but it doesn't lean on it, it just acknowledges their existence and moves on.
