Blue Field (ブルー・フィールド)

"Blue Field" (ブルー・フィールド) is the first ending theme for the 2013 television anime Arpeggio of Blue Steel: Ars Nova (Aoki Hagane no Arpeggio: Ars Nova), which SANZIGEN animated. Mai Fuchigami, Manami Numakura, and Hibiki Yamamura perform the song, and it was released in Japan as a CD single on October 30, 2013.

The track is shaped as polished J-Pop, with a bright pulse, a clean melodic line, and a trio vocal blend that keeps the performance smooth rather than forceful. corin's arrangement gives it steady forward motion, while Heart's Cry wrote both the lyrics and the music.

As ED 1, "Blue Field" closes the series on a lighter surface than its oceanic warfare suggests, yet its controlled momentum still suits a story driven by tension, movement, and fragile alliances at sea. The single, catalog number VTCL-35167, also includes the coupling song "Innocent Blue" and instrumental versions of both tracks.
