The group has increased with three female members since then, making them a sixtett. Asuka is currently on maternity leave, so she does not appear in the jacket picture, but participates on vocals.
This single will be published by Mikkamachi Saneikai, the country's first shopping district label, based in the hometown of one of the members, Hachinohe in Aomori Prefecture in the northernmost part of Honshu. The single contains three new songs, plus a re-recording of one song off their debut album, for a total of four tracks. The double A-sides are "Hayabusa wa Omoi wo Nosete" ("Hayabusa Carries My Love"), a song about hometowns created with the image of the Tohoku Shinkansen Hayabusa, and "Que Sera Sera", a message song to soothe the hearts of those who are worn down by daily life. "Que Sera Sera" is a message song for all those affected by the work and time constraints and the hecticness of daily life. This song makes a strong impression with the first line of the chorus: 花になって風に舞って、立ち止まって力抜いて (= Become a flower and dance on the breeze, stand still and relax), and makes good use of the mixed male/female vocals. "Hayabusa Carries My Love" is a heartful melody reminiscent of a pastoral song, using the Tohoku Shinkansen Hayabusa to convey the feelings of love for one's hometown from the people who come and go. Music and lyrics are by Saiki$STONE, who you will remember from their first album. They are a talented up-and-coming creator unit who have won many awards in various contests over the years and whose song "Jigsaw Puzzle" for Sonim charted at 9th on the Oricon charts in 2004.
