“New Genesis” (新時代, shin jidai — “new era”) is the song of Uta, a world-famous singer in One Piece Film: Red (2022), voiced in song by Ado. Uta wants to create a new era: a world where no one suffers, where everyone can be free and happy, forever. The song is joyful and determined — though the film reveals the dark side of her dream.
The film was a huge success, and the song topped charts across Japan and Asia; Ado's powerful voice made it one of the defining anime songs of the year.
The Japanese is clearer and slower than her earlier songs, so it's B1. The vocabulary of dreams and change — new era, world, freedom, to change — is useful far beyond anime.
