10-FEET have released “Fortress Defense,” a digital single written for the first cour of TV anime 『アオアシ Season2』 (Aoashi Season 2). The track arrived in Japan on October 5 through EMI Records.
The song was made specifically for the series. On the anime’s official site, bassist NAOKI described it as high-tension and driven by the feel of the band playing live; drummer KOUICHI likewise framed it as a track designed to lift the listener’s energy. Those comments point to the role 10-FEET were aiming for: an opening built to hit immediately as the new season moves into its A-team arc.
The release was accompanied by a music video from 10-FEET and a creditless opening sequence from the anime. “Fortress Defense” is now available digitally, with the opening offering the clearest first look at how the band’s charge has been placed inside Aoashi Season 2.
