[5] Expressing interest in music since middle school and inspired by the Japanese pop/electronic group Perfume,[6] Avu-chan formed the band Queen Bee in 2009 with classmates in Kobe, Hyōgo Prefecture.
[7] The band made their first major concert appearance at the Fuji Rock Festival in July 2010,[8] where they performed as a part of the very selective "Rookie a Go-Go" section, sometimes called the "road to success" for new artists.
[12] Not long after signing a contract with Sony Music, Queen Bee found early success with their song "Desco", which was featured in the romantic comedy film Moteki (2011), where the band had also made a cameo.
After spending some time in the studio, the three were later joined by guitarist Ryosuke Nagaoka from Tokyo Jihen, whose presence Avu-chan described as "essential", as it gave a sense of unpredictability to the group.
[13] The newly formed supergroup, now known as Gokumontō Ikka, made their debut performance at the Rising Sun Rock Festival in August 2013.
[13] During the hiatus, Avu-chan also collaborated with singer Mariko Gotō for Pretty Guardian Sailor Moon: The 20th Anniversary Memorial Tribute in 2014, performing a cover of "Ai no Senshi".
In the same year, Avu-chan collaborated with a South Korean boyband Supernova, writing and performing on the leading track "Jesus", from their sub-unit Funky Galaxy's debut extended play.
[17] The packaging for the limited edition of the split single was styled to resemble PlayStation fighting games, with the cover art illustrated by Kinu Nishimura, whose work on the Darkstalkers series has been considered a longtime favorite by Avu-chan.
[25] In late 2020, Avu-chan produced the song "Ōkami Seinen" for an anonymous boyband called Honey Bee,[26] who were later revealed to be Hey!
