In "UNIVERSE TICKET" episode 8, trainees face new challenges as they battle in "UNIT STATION" and face promotions and dropouts.

In the 8th episode of "UNIVERSE TICKET" broadcast on January 3rd, the next battle "UNIT STATION" began. Trainees are divided into two units, Position Unit & New Song Unit, to perform on stage. In the Position Unit, there are promotions, and in the New Song Unit, there are dropouts. Also, it was revealed that the Position Unit's stage is divided into a total of 3 units, and only one trainee per position can be promoted. The episode started with the visual unit's practice scene featuring Nana (Japanese), O Yuna, Yona, and Kotoko (Japanese) from the girl group PRIKIL. Kotoko expressed confidence in her ability to perform well because she likes the song. Nana revealed that Kotoko is her rival because the song suits her. After discussion, Nana, Kotoko, and two Japanese trainees decided to challenge the killing part. In the mid-evaluation, Nana received 8 votes for promotion, and Kotoko received 9 votes. In the final performance, Kotoko performed "Catallena" by ORANGE CARAMEL and received high praise from the Unicorn members and producers. As a result, Kotoko was promoted from S rank to I rank. In the vocal unit consisting of Kim Sujin, Pan Yuna, Elysia, Lee Sonu, Lee Fran, Im Sowon, Zelidanca, and Jin Hyunjoo, an accident occurred when Im Sowon was infected with the flu during practice. She managed to recover and join the group for the recording, impressing the Unicorn members. As a result, Im Sowon was promoted from I rank to R rank. In the performance unit consisting of Ku Gyorion, Narumi (Japanese), Niji (Japanese), Pe Yeram, Pe Halam, Yuri (Japanese), Jeong Jin Young, and Jaela (Japanese), Narumi was unable to secure enough votes for promotion despite winning the solo dance part. In the final performance, the Unicorn members praised both Niji and Narumi. Narumi was promoted from S rank to I rank. In the tense result announcement, Narumi was announced to be promoted from S rank to I rank. Next week's broadcast on January 10th (Wednesday) will feature the final stage before the final stage, a battle over the new song "UNIT STATION." However, it was revealed that the dropout from the New Song Unit will be determined not only by the Unicorn's choice, but also by the participants from the other unit.
