Concept
The box set was created to look like a medicine case. As the set was composed of 8cm singles, Sheena thought back to the 1980s, the era of 8cm singles and thought of idol Hiroko Mita, who had appeared on many posters for medical products, acting as if her stomach or head hurt. So for the promotional posters, Sheena stood with her head or stomach in pain, with the Ze-Chyou Syuu case advertised on top, as if it were medicine. The set is composed of three 8cm CDs, each featuring a performance from a different band. Disc 1 features performances by Gyakutai Glykogen from Gekokujō Xstasy. Disc 2 is a collection of studio recordings with Tensai Präparat. Sheena intended for these to be live recordings from their Manabiya Tour, but as the sound quality was not what she wanted, she decided to re-record them. Disc 3 contains three songs from the Hatsuiku Status: Gokiritsu Japon tour. Two of the songs were given mojibake titles in the Ze-Chyou Syuu booklet: "Onaji Yoru" was written as, and "So Cold" as.
Promotion
"Yattsuke Shigoto" from given a music video to promote the release. It was shot on the day of the dress rehearsal of the one-night stand live Zazen Ecstasy performed at Kaho Theater of Iizuka-shi, Fukuoka in 2000. All extras playing spectators in the theater were her fans, and they were chosen from her fans who drew a blank in the lottery of the live ticket. The parody of the news report of the various countries in the worldat the beginning is used as the introduction part of the music of different arrangement recorded in her third album Kalk Samen Kuri no Hana. In 2006, "Yattsuke Shigoto" was covered by :ja:ケラリーノ・サンドロヴィッチ|Kera and the Synthesizers on their third album Tonari no Onna.
