The title of the song is taken from a Hawaiian proverb meaning “If it doesn’t rain, there will be no rainbow.”
The official YouTube channel for voice actress/singer Nana Mizuki has started streaming a 45-second preview for “No Rain, No Rainbow,” one of the two title songs in her double A-side 40th single “FIRE SCREAM / No Rain, No Rainbow,” to be released on October 7, 2020.
The upbeat tune will be featured as the new OP theme for the TV anime Duel Masters King from its next 23rd episode to be aired on October 4.
