Serving an expository function, the Narrator delivers contextual historical information at each episode's start. This narration grounds the story in Japan's Bakumatsu period from approximately 1861 onward, covering pivotal events like Ii Naosuke's death and the arrival of Commodore Perry's Black Ships. It details relevant folktales and technological developments such as clockwork doll origins. Consistently bridging fictional events with Japan's historical opening to Western influences and ensuing societal tensions, the narration never interacts with characters or influences the plot directly. No personal backstory, development, or involvement beyond providing this contextual framework is established.
