Six versions of the single exist: a CD only version, two DVD editions, and three Mu-Mo store exclusive versions. DVD edition A featured the music video for the song, while DVD edition B featured a documentary on the making of the music video for their previous single "Aitai Riyū."
All versions feature "Makenai Kokoro" and "Day By Day", while only the CD only version features the group's cover of H Jungle with T's 1995 number 1 single, "Wow War Tonight (Toki ni wa Okose yo Movement)". The Mu-Mo exclusive versions each feature one of three live talk tracks, where the band members discuss the time since their debut in 2005.
