Re: I Am

"Re: I Am" is the fifth single by Japanese singer Aimer, released on March 20, 2013 under Defstar Records. Written by Hiroyuki Sawano, the song was used as the theme song of episode 6 of the mecha anime OVA series Mobile Suit Gundam Unicorn, as well as the opening theme of episode 18 of the OVA's TV edit version Mobile Suit Gundam Unicorn RE:0096. The single peaked at No. 6 on the Oricon Singles Chart and No. 27 on the Billboard Japan Hot 100.

According to Sawano, he selected Aimer among a list of vocal candidates to record the song, as he was drawn by her husky voice. At the same time, he was concerned with her voice, which she injured in a vocal accident when she was 15. This was Aimer's first foray into rock-based music, as her prior releases were ballads. The song's title is an anagram of Aimer's name.

The song was written in English by Benjamin Anderson and mpi and re-recorded by Aimer in the 2014 SawanoHiroyuki[nZk] :Aimer collaboration album UnChild.
