Nobody talks about TRIGGER's anniversary videos. That needs to stop. This one doesn't coast on nostalgia or franchise goodwill, it builds an actual narrative inside the song, where every lyric lands like a plot point and the animation moves with the music like they're the same thing. You watch it once for the visuals. You listen again because the song reveals something the images didn't show you the first time.

Hidden Region is a single music video for the song of the same name, performed by the group TRIGGER. The video was released to celebrate the franchise's seventh anniversary. It is the third entry in a run of lyric videos, with one put out for each of the group's anniversaries. The result is a short mystery-flavored music video.
