The debut single, (released July 2020) featured bright synth‑pop arrangements and lyrics centered on youth and hope. While the song performed modestly on the Oricon charts (peaking at #42), it established the group’s core aesthetic: a bright, youthful visual style paired with production that leaned heavily on electronic dance beats and layered vocal harmonies.
