The offiicial website for the television anime adaptation of Tetsuro Kasahara's Atom the Beginning manga announced on Thursday that the musical duo After the Rain will perform the opening theme song "Kaidoku Funō" (Indecipherable). The song's single will ship in Japan on April 12.

The duo also announced on Thursday that they are performing the opening theme song "Anticlockwise" for the Clockwork Planet television anime series. That single will ship simultaneously with the "Kaidoku Funō" single.

The musical duo is composed of Soraru and Mafumafu. Soraru is in charge of vocals, mix, and mastering, while Mafumafu also performs vocals and composes music, writes lyrics, and arranges songs. The duo debuted with the album After Rain Quest in 2014. The musical unit released Kuro Crest Story in 2016, and the album attained the second spot on the Oricon weekly music chart. The pair performed the opening theme song "First End" for Reikenzan: Hoshikuzu-tachi no Utage last year.

Atom the Beginning's story takes place in Japan after a great calamity. There were two geniuses who dreamed of the future. One was Umatarō Tenma. The other was Hiroshi Ochanomizu.

The two labored day and night in robot research — Tenma to create a "god," and Ochanomizu to create a "friend." Thus a robot, A106, was born from their collaborative friendship. Would A106 really become a god, or a friend? The young brilliant duo glimpsed the impending future…
