In a quiet and mysterious town, life is as gentle as a gurgling stream, but it is rippled by a group of boys and girls.
Hang, who has a cheerful and energetic personality, meets Yui, who is gentle and has a secret in her heart. Their life is like the chirping of cicadas in summer, free and comfortable, but the ancient Tsukiyomi Festival in the shrine is like an invisible hand, pulling them into the whirlpool of fate.
With the exploration of the secrets of the Tsukiyomi Festival, the dusty past events are revealed one by one. The mysterious ancient paintings in the shrine, the inexplicable runes that appeared in the rituals, and the previous generation of witches who seemed to be inextricably linked to them, everything became confusing. In the process of restoring ancient paintings, Matsumoto Saki accidentally discovered the secret connection between the family and the shrine; Haruka used his scientific and technological talents to solve the mystery behind the shrine's mechanism; the participation of Nana's Taiko, Fujii Takuma and Miyazawa Midori also made this adventure more exciting.
In this small town full of Japanese characteristics, the seaside train shuttles between cherry blossom trees and shrines. The story of their youth is woven into a moving piece under the chirping of summer cicadas and the blowing of the lost wind. What kind of unexpected ending is waiting for them?
