As soon as the show starts, the 82 contestants face Battle Week, where half of them will be eliminated. The first battle, 1-on-1 Battle, commences, and the girls are to pick their opponents and go up against each other. The low-ranking contestants unexpectedly put on amazing performances, surprising the judges. Who will make it to the next battle, and who will be eliminated? Stay tuned to find out!

After the 1-on-1 Battles are over, the girls are divided into winners and losers. The final battle of the Battle Week is revealed, and after the last battle, only 41 of them will survive. The final battle, the Revenge Battle, is a team battle between the winners and losers of the first battle. The winners get to choose their teammates, concepts, and songs, whereas the losers must follow everything decided by the winners and battle against them.

The Revenge Battles continue. Enchanting Winners show a disappointing performance, while Enchanting Challengers put on a surprisingly good performance. Pure Winners face a crisis as one of the members hits her limit. The pressure to win the battle grows bigger, and some of the contestants become overwhelmed. Which team will overcome the pressure and take a win?

Charismatic Winners present “DDU-DU DDU-DU,” while Charismatic Challengers perform to “FIRE.” The judges are torn as both groups do an excellent job. After the Revenge Battle, the 20 contestants advancing straight to Universe through Unicorn Ticketing is revealed. The rest must make it to the Universe through their fan voting. Who will be among the 41 contestants to advance to the Universe?
