Ghost in the Shell is a 1995 adult animated neo-noir cyberpunk thriller film[8][9] directed by Mamoru Oshii and adapted by frequent Oshii collaborator Kazunori Itō. The film is based on the manga of the same name by Masamune Shirow.

Composer Kenji Kawai scored the film. For the main theme, Kawai tried to imagine the setting and convey the essence of that world in the music. He used classical Japanese in the opening theme “Making of a Cyborg”.[16] The composition is a mixture of Bulgarian harmony[21][22] and traditional Japanese notes; the haunting chorals are a wedding song sung to dispel all evil influences.
