Mushishi, Dororo Recommendations
Both protagonist are foreigners with unique vision who help the locals get rid of creatures. The era and the setting are also really similar. This series is like a darker and not so episodic version of Mushishi.
Both series have a comparable mysterious ambience to them, and kind of give off a similar vibe - especially with their somber art styles. Although they don't have the same plot, Dororo almost feels like a more action-packed Mushishi to me, dealing with strange 'out of this world' creatures. They also take place close to the same time period in Japan - Dororo being during the Sengoku period, and Mushishi between the Edo and Meiji periods.
-similar animation and a similar mood; quiet, suspenseful, mysterious, adventurous, and dark
-has a certain "spiritual" feel to it like Mushishi when it comes to the story and characters which brings in a good amount of emotion
-set in an older time of Japan; Sengoku period whereas Mushishi was around the Edo period
-both main characters set out to deal with supernatural entities
-man vs nature (sort of)
