Hologram was released in 2009 by Japanese rock band Nico Touches the Walls and served as the second opening theme for Fullmetal Alchemist Brotherhood, playing over episodes 15 to 26. Its anime sized version became inseparable from the series' second arc, when the story expands beyond Amestris and introduces new homunculi threats. Clips of the chorus spread through early AMV communities on video sharing sites and later on anime TikTok and YouTube edits, where the instantly recognisable hook still signals a classic shonen opening to fans worldwide today.
