It is the group's first album that does not feature all six members, as Jin Akanishi had taken a sabbatical to study overseas six months prior to recording the songs.

The last performance at Tokyo Dome was filmed and released on DVD entitled "Tour 2007 Cartoon KAT-TUN II You" on November 21, 2007.

Yoji Kubota, a prolific lyricist for many of Japan's contemporary pop artists, wrote "Movin on..." with arranger Nao Tanaka and also penned "Heartbreak Club".

The fourteenth track, "You", was not officially released as a single but a music video was shot marking Jin Akanishi's return to the group.

[6] In its first week of release, Cartoon KAT-TUN II You sold 270,976 copies in Japan, a sharp drop from the first-week sales of their debut album.
