The leader and lead rapper of the group, Shinya Taniuchi, chose the songs to be placed on the album and conducted them to flow into each other.

[1] The album was released digitally on various streaming sites, including iTunes, Apple Music and Spotify.

Shinya also composed the tracks to where they would flow into each other, creating a non-stop mix by taking control as the album's DJ.

The album was a continuing factor in Lead's participation in Japan's "stay at home" order due to COVID-19 to bring entertainment to the country's residents.
