About
June 26, 2020. In the final episode of the global audition "Nizi Project," the nine debut members were decided, and the new girl group "NiziU" was born. This day marked the starting line for their dreams and the beginning of a new life for the nine members. As it is still before their official debut, the members are living together in Korea, preparing through lessons, recording, and filming, while gradually deepening their bonds as a group. Every day is a mix of anticipation, tension, anxiety, and hope, but not a single one of them thinks of giving up. They have just begun their journey with the shared goal of "completing the rainbow with nine people."
