The story is very memorable. I pretty much recalled 90% of the plot, as I was watching. This story is very 2000s anime-like. It was clearly influenced by stuff like Elfen Lied, which was also roaring at the time, and perhaps even Kanon - with the whole "guy returns to his hometown and rekindles old friendships with nearly-forgotten people."
The most memorable plot-point to me, was the old lady with the animal and human sacrifice. I think that it's actually important to bring the topic out to daylight. Sacrifice used to be a thing across the board in human societies. It's not just the Vikings and peoples from Mesopotamia who practiced it. As time moved on, humanity abandoned this practice in favor of animal sacrifice, and that was pretty much abandoned too, eventually. But, enough with the history...
Yes, this old piece is still worth a watch, I'd say. It's an adaptation of a light novel of 6 chapters (or volumes, not sure about the source's accuracy). It's one of those stories that are short enough to be told over 13 anime episodes.
BUT
The light novel was never translated to English. So, for non-Japanese speaking people, this anime is the only source we've got. Most of the media files out there, are 2000s-quality rips. So, it's also pretty low quality. Nonetheless, if you want a short story *that actually ends like in the source material*, go delve into it.
