Her Blue Sky (2019) Plot Summary

In Chichibu, 18-year-old Shinnosuke Kanamuro (nicknamed Shinno), who is an aspiring guitarist is dating Akane Aioi. Shinno is also friendly with Akane’s 3-year-old sister Aoi, and in turn the sisters support Shinno’s band. Akane plans to move to Tokyo with Shinno after graduation, where he’ll pursue a career in music. However, the girls’ parents are killed in a car accident and Akane changes her plans, choosing to stay in Chichibu to raise Aoi.

Thirteen years later, Aoi is an aspiring bassist who plans to move to Tokyo after high school, while Akane works for the city hall. Masamichi Nakamura (nicknamed Michinko), the drummer of Shinno’s former band, also works for the city hall. Michinko is planning to hold a music festival to boost the city’s tourism, and the main performer is the famous enka singer Dankichi Nitobe.

One afternoon, while practicing bass alone in the hall, Aoi encounters Shinno from thirteen years ago. Frightened, she runs home to Akane and awkwardly asks her about Shinno. Akane admits that she has not heard from Shinno since he left, and is not even sure if he is still alive. This leads Aoi to believe she had seen Shinno’s ghost. Later, the sisters reluctantly help Michinko in welcoming Dankichi Nitobe, and they are surprised to see a grown Shinnosuke as the guitarist of Nitobe’s backup band. Aoi then returns to the hall with her friend Tsugu (Michinko’s son), where they confirm that the young Shinno has a physical body but is unable to leave the hall. Tsugu hypothesizes that Shinno is an ikiryō (living ghost) born from Shinnosuke’s strong unresolved feelings. Shinno then asks Aoi to help bring Akane and Shinnosuke together, believing that doing so will return him to Shinnosuke’s body. However, this proves to be difficult as Shinnosuke is rude, arrogant, and does not get along with the Aioi sisters—a different person from the Shinno that they once knew.
