Rurouni Kenshin: Meiji Kenkaku Romantan - Tsuioku-hen, Dororo Recommendations
Mind you, I'm on the fourth episode of Dororo while writing this.
Although the OVAs of Rurouni are set right before the beginning of the Meiji era (mid 19th century) and Dororo during the Muromachi era (mid 14th to late 16th century), both are grim Jidai Geki that treat war as absolutely loathsome, showing how it scars (metaphorically AND literally) people and how violence and tragedy just breeds even more violence and tragedy.
-Both shows involve Samurai.
-Both shows are set in feudal Japan.
-The main character learns more about his emotions as the story goes on.
-Both are about war and the effects it leaves on people.
