This episode was again full of ingenious plot twists. The borders of good and bad get thrown aside, even more than what happened in the previous episodes. Furthermore, we get some nice moral issues put in front of us.
Overall, I liked this episode. It is by no means the best Mushishi has ever delivered, but I still enjoyed this while watching. The view of immortality was also nicely executed, without making it seem too powerful. I was also really surprised at the desicion the guy made at the end. Any other character from any other anime would have made the other choice.
