Anicca

“Anicca” is a J-Pop song performed by Hitomi Harada and used as the first opening theme for the 2013 television anime Machine-Doll wa Kizutsukanai (Unbreakable Machine-Doll; 機巧少女〈マシンドール〉は傷つかない), produced by Lerche. It was released on November 27, 2013 as Harada’s fifth single.

The track moves with brisk pop momentum, pushing forward on a tight rhythmic pulse before opening into a more urgent chorus. Harada’s vocal line stays clear and bright, but the refrain carries extra tension, giving the song a sharper edge than a purely buoyant idol-pop performance.

That balance of lift and pressure fits a series centered on combat, automatons, and rivalry at a school of Machinart. The single also included the B-side “Overdrive” and reached No. 39 on Oricon. Lyrics were written by Lyu:Lyu / Tomoyuki Nakano, with music by Tatsuya Kurauchi and arrangement by Butch Walker.
