Also, first pressings of the CD+DVD edition included a serial number to access a special website broadcasting making-of material of Ayumi Hamasaki Countdown Live 2010-2011 A: Do It Again.
Many netizens have wondered why this mini-album was named Five, if it was just because the album has only 5 tracks. On the Sweet interview, Hamasaki hinted that there is a hidden word in the title of the mini-album, 'H♡PE', which was figured out by her fans. They predicted that Five was released not only because it has 5 songs, it was also 5 months after the disastrous earthquake and tsunami that hit Japan in March. For the first time, Hamasaki undertook the artwork of the font design herself.
