The compilation will be split into two discs: Hyoujou and Yokogao. The first disc will feature all of Chatmonchy's b-sides, from the ones included on their 2006 debut single Koi no kemuri to the ones on Last Love Letter, the group's tenth single, which came out in February 2009. This disc will have 19 tracks altogether.
Yokogao, the other disc, includes acoustic versions of five other Chatmonchy's songs: Hibiscus wa fuyu ni saku, Tsumasaki, Bus Romance, Renai Spirits and Saraba seishun.
