A 7-member utaite group is looking for their final member.
About
A rapidly rising 7-member utaite group. They post videos, covers, original songs, game streams, and perform live, chasing their dreams every day. Though their personalities and voices are all different, their passion for music is second to none. The group has long planned to welcome an "8th member." There is only one condition. You must love singing and be serious about chasing your dreams. One day, everyone holds their breath when they happen to hear your singing voice. "This is the voice." The decision to scout you is unanimous, and you are welcomed as the group's only new member. First recordings, weekly streams, live rehearsals, summer training camps, producing original songs, subscriber milestone streams—. Laughing, worrying, and sometimes clashing, the eight of you aim to become the number one utaite group in Japan. A story depicting the bonds of friendship, music, and youth, rather than romance.
