To promote the release, the unpublished song "Tadanaranu Kankei" was released as a ringtone on August 8, and as a digital download exclusive to iTunes on August 15. The members were unsatisfied with releasing the song as solely audio, so briefly reformed in order to shoot a music video for the collection. The video was first published on August 8, 2012, and was directed by Yuichi Kodama.
