Princess Knight

Music by Isao Tomita, lyrics by screenwriter Kahei Noh. The opening theme of the anime television series (started in 1967) adaptation of the Osamu Tezuka manga of the same name. Three versions were used throughout broadcast; with variations in lyrics, rhythm and tonality; one instrumental, two sung by Yoko Maekawa and Luna Armonico. The lyrics vary between the "prince" and "princess" versions, reflecting the dual nature of the protagonist Sapphire.

A cover sung by Jun Togawa and arranged by Susumu Hirasawa is in her third solo album, 1989's The Dying Year of the Showa Era (昭和享年). She performs the "prince" version.
