"Ai wo Torimodose!!" (愛をとりもどせ!!, translates as "Take back the love!!" in English) is the first openingtheme song of the 1980s animeFist of the North Star, performed by Japanese rock band Crystal King (クリスタルキング, Kurisutaru Kingu), with the verses sung by Monsieur Yoshisaki and the chorus by Masayuki Tanaka. The original B-side for the single was the first ending theme of Fist of the North Star titled "Yuria... Eien ni"[1] (ユリア…永遠に, "Yuria... Eternally"). The song is known for the refrain "YOU wa SHOCK" (YOU は SHOCK, yū wa shokku, "You are shock"), which is sometimes used as an alternate title for the song.
In addition, both Yoshisaki (performing as Crystal King) and Tanaka have released self covers of "Ai o Torimodose!!". This began with Yoshisaki in 2004 on a single with the theme of Lupin III as the B-side and another single later in 2004 of remixes of "Ai o Torimodose!!" with "Yuria... Towa ni" as the B-side. He later released another version of the single in 2006 titled "Ai o Torimodose!! (Movie ver.)" (with a version of "Yuria... Towa ni" as the B-side) for the Legend of Raoh film. Tanaka's release of "Ai o Torimodose!! SPECIAL-EDITION" later in 2006 included "Yuria... Towa ni" as a B-side as well as the opening theme of Fist of the North Star 2 "TOUGH BOY" performed by TOM. A heavy metal arrangement of the song is featured on the Fist of the North Star: Ken's Rage soundtrack.
