"Ai o Torimodose!!" (愛をとりもどせ!!) is the first opening theme song of the anime Fist of the North Star. The song's title literally translates as "Take back the love!!" in English and is performed by the rock band Crystal King (クリスタルキング Kurisutaru Kingu). The verses are 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... Towa ni" (ユリア…永遠に, "Yuria... Eternally"). The song is known for the refrain "YOU wa SHOCK" (YOU は SHOCK yū wa shokku, lit. "You're in shock"), which is sometimes used as an alternate title for the song.
