Takizawa Bakin appears within the narrative as an elderly, blind writer and grandfather to Meido, an aspiring author documenting events surrounding the fuse. His character embodies the historical novelist Kyokutei Bakin, creator of the foundational epic *Nansō Satomi Hakkenden*, which directly inspires the story's world and the concept of the fuse beings.

Portrayed during his later years, his blindness integrates into the narrative through Meido’s support as she transcribes his stories, mirroring the historical assistance Bakin received from his daughter-in-law. His presence underscores the thematic exploration of storytelling and the fluid boundary between fiction and reality, as Meido’s documented events draw influence from his own literary legacy.

Takizawa Bakin’s role remains ancillary, contextualizing the origin of the fuse mythology and reinforcing the film’s literary connections via his relationship with Meido, without detailed narrative arcs, specific actions, or dialogue.
