Again (Fullmetal Alchemist: Brotherhood OP)
Yui
"Again" is Yui's pop-rock anthem opening the 2009 *Fullmetal Alchemist: Brotherhood*, one of the most beloved anime theme songs of its era, fusing emotional weight with driving energy. It launches with a memorable a cappella vocal flourish before crashing into urgent guitars and propulsive drums, a structure that immediately signals both intimacy and momentum. Yui's voice is the heart of it — clear, slightly fragile, yet capable of real power, carrying a wistfulness that suits the series' themes of loss, guilt, and the longing to undo the past. The Japanese lyrics speak of regret and the wish to return to a former self, of carrying scars while still moving forward, mirroring the Elric brothers' central quest. The production keeps things bright and rock-forward without sacrificing tenderness, a balance that made it resonate far beyond the show. Culturally it stands as a defining J-rock anime opening, instantly nostalgic for a generation of fans and a staple of anime playlists and karaoke sessions worldwide. It's a song for emotional moments, for nostalgia, for the bittersweet pull of memory. Earnest and stirring, it captures that uniquely anime-theme alchemy of pop accessibility and genuine feeling, the sound of someone choosing to keep going despite the weight of the past.
