A kid with a sword and pure stubbornness versus demons that don't care about his heart. Tenmaru doesn't win because he's special, he wins because he refuses to stop, and that refusal becomes the whole reason to watch. This is 1983 adventure anime before it learned to apologize for sincerity, when a demon slayer could just be a demon slayer and that was enough to carry you through nineteen episodes without irony or exhaustion.

Tenmaru is a demon slayer, and the story follows his adventures as he takes on demons. The 1983 TV anime runs 19 episodes and mixes adventure with fantasy, built around a hero whose work is hunting down supernatural foes.
