Participants

At the end of the auditions, 4 girls passed through to join Up Up Girls (2). The ranking played no part in did not influence their passing/failure.

Additions & Aftermath
Although a 5th member, Nakaoki Rin, was added shortly after the announcement of the first 4, she was not part of the audition process. She was not included in any SHOWROOM or twitter accounts prior to her official addition. Since she did not have to audition to join the group, she is not included on this page nor in the successful participants page. Besides Nakaoki Rin, two additional members were added to the group in April of 2018 on the groups 1st anniversary. Both girls were chosen during the initial auditions to be trainees. After their training was completed, they joined the group.

Mayuhokki, Aoyama Mayu, was not chosen but participated in a Hokkaidou based event with Up Up Girls (Kari). For a period of time she was being promoted by YUM Entertainment and Up Up Girls (Kari). She was given the job of reporting on Kikkawa Yuu and Up Up Girls (Kari) while they were in Taiwan. It appeared as if they were training her to join Up Up Girls (Kari) or (2), which lead to many fans being shocked by the announcement of the addition two members. It appears as if she no longer has plans to join UUG (K) as she hasn't mentioned her intent in over 3 months. Since reporting in Taiwan, she was joined several SHOWROOM events, such as Tanaka Reina's program and a chance at voicing an anime character. Her current status is unknown. She is currently on rotation as host of Shimokita FM's Idol Live.
