Movie
Description
Encountered by Yuta at Hotarugaoka Dam, the elderly "Old Man Hotaru" initially appears exhausted and accepts water from the boy. When a storm causes Yuta to fall from the dam, this same figure rescues him, triggering Yuta’s displacement thirty years into the past.
In 1977, he simultaneously exists as Tatsu, the younger shrine priest known as "Blue Tengu" (Aotengu). Aware of Yuta’s time displacement, Tatsu serves as his guide and explains the boy must remain for one month before returning. His actions center on the village’s impending dissolution due to dam construction, where he oversees preparations for the final summer festival—marking the community’s end.
He is revealed as Saeko’s grandfather, a familial link crucial to the narrative. Orchestrating the story’s resolution, he reappears in elderly form after Yuta returns to the present. There, he facilitates a reunion between adult Yuta and Saeko—previously presumed dead—resolving a core emotional conflict. This act confirms his transcendence of temporal boundaries, motivated by addressing unresolved grief tied to the village’s flooding and Saeko’s fate.
His existence across timelines embodies cyclical time and reconciliation, positioning him as a guardian of memory. He deliberately manipulates events to heal generational trauma, forging connections between past and present while facilitating closure for the village’s history and personal losses.
