Lyric

Reiwa's strongest JK gravure queen "Miyuka Minami" (17 years old), who is making a big break nationwide with a super body full of transparency, such as decorating the cover of Young Magazine three times, and fashion magazine "Cuugal" model "Kokoro Nishino" (14 years old), "Misaki Yumeno" (16 years old) who decorates models for various magazines, and "Hiyori Momose" (16 years old) who has a reputation for singing ability, and was selected from her high potential in 8 months since her debut. A miracle teen influencer idol "O2" consisting of "Yuina Nohara" (15 years old).

Her long-awaited digital debut song "Blue Bird ~Adventurers~"
With the concept of their catchphrase, "One page of blue blue youth...with you...beyond the aqua blue...", they will travel around the world with their fans in search of the blue bird. A story condensed into one song. From the fantastic intro of Celtic folk music, to the refreshing track with the image of the sky and the sea, beautiful melody and powerful chorus full of uplifting feeling. And their singing voices full of youth are wonderfully fused. A one-of-a-kind fantasy song that lets you fully enjoy the feeling of running through the seven seas with them! !
