Futaba helped form the girl band AZALEA in high school alongside Nanami Kuon and Ichika. Initially nameless, Futaba suggested naming them "AZALEA," inspired by the flower symbolizing "the joy of youth," a choice embraced by the group. They debuted at their school festival, pledging to continue after graduation. Moving to Tokyo, AZALEA faced obscurity and nearly quit music until producer Toshihiko Karasawa discovered them. He offered a contract with Key Time agency on the condition they abandon their rock style for a pop image, choreography, and costumes dictated by him. This shift conflicted with their original identity but propelled them to fame. During the "100,000 Likes" challenge, AZALEA served as rivals to Eiko Tsukimi's group. Witnessing Eiko and Kabetaijin's authentic street performances reignited AZALEA's passion for their initial rock sound. This prompted Nanami to renegotiate their contract with Karasawa, securing the freedom to retain their artistic integrity while maintaining their professional collaboration.
