アンチクロックワイズ (Anti-clockwise) is a pop track by After the Rain (そらる×まふまふ), a utaitou duo formed by vocalists Soraru and Mafumafu. The song was composed, arranged, and written by Mafumafu, with mixing handled by Soraru. It served as the ending theme for the 2017 anime series Clockwork Planet (クロックワーク・プラネット), whose clockwork-and-gear motif is directly reflected in the title, "Anti-clockwise" being the British English term for counterclockwise. The song was originally released as a single in 2017 and later made its rhythm-game debut in maimai MiLK PLUS on June 21, 2018, where it was included from the version's launch alongside a complete set of charts including a Re:Master difficulty. In Asian English releases of maimai, the title was romanized as "Anti-clockwise" and the artist label was simplified to "After the Rain". The song was removed from the game on March 21, 2024, making it unavailable in standard rotation. Two official music videos exist for the track, an animated version and a live-action version, with the live-action video being used as the in-game jacket and preview footage. The lyrics explore imagery of a broken clockwork world, faded skies, and rusting gears, weaving together the series' mechanical aesthetic with themes of lost time and yearning.
