Came across this series online looking for horror anime. I guess the series i watched was the more recent of the 2. While I wouldn't classify it has horror exactly, it was definitely dark. The only real issue I had was the main male character was quite unintelligent for being so old. I would think an immortal would be a bit smarter than he was. Otherwise it was interesting and quite violent and bloody. Not gory, but very bloody. Showcases the worst of humanity when immortality is within reach. I enjoyed not having all the silly faces and over the top reactions like in many other animes I've seen. It's worth a watch.
