While keeping the setting of "Town of Evening Calm" as is, the 2004 setting of "Country of Cherry Blossoms II" was moved to 2018, and the characters were also aged by 14 years.
The role of accompanying Nanami to Hiroshima in pursuit of Asahi was replaced by Fuko, Nagio and Toko's daughter, and Toko does not appear in this work because "Country of Cherry Blossoms I" was cut.
