Khun learns the truth from Hwaryun and decides to join Wangnan's team in the Workshop Battle. Meanwhile, Bam remains on Team FUG as Viole.

The Hand of Arlen is destroyed by FUG. Wangnan's team rescues Khun from the rubble, who explain that the long-haired man he saw is FUG Slayer Candidate Jue Viole Grace. While contemplating recent events, Khun encounters a familiar face...

Viole witnesses Kang Horyang's defeat and unleashes an incredible power. Meanwhile, Khun realizes he has been betrayed and rushes to save his teammates.

Kang Horyang leaves to look for Cassano alone. Unable to abandon their teammate, Viole and the others go after him.

Kang Horyang shares his past with his teammates and asks Viole about the source of his power.

Both Khun's team and the team of Wangnan and Viole continue to climb the tower, facing the necessary trials along the way. In the process, they discover a new tool: the increasingly popular chat AI, Emile.

The battle against Urek continues in Zygaena. In a deadly game between Urek and Viole, the stakes are Zygaena's flower. But then, everything takes an unexpected turn.

The team with Viole and Wangnan faces the next test on their journey to the top of the tower. But before that, they are evaluated by Viole's friends from FUG.

Khun continues to climb the tower, thinking of his best friend Bam. He has assembled a new team and is dragging along the sluggish Rachel. But there's much more going on behind the scenes.

In the test on the 20th floor, the examinees are supposed to form teams and capture rooms. However, trust is a rare resource in a world that rewards betrayal.

Viole refused to choose companions for the journey ahead. Therefore, another test is being conducted to resolve this issue.

Once all the successful candidates had gathered, the second test began. However, the Test Director makes a strange proposal to Viole, who passes the test with top marks.

On the twentieth level, there is another test to determine who may continue to climb the tower. Many who have failed and buried their dreams gather there. However, Ja Wangnan does not want to give up and puts everything on one last chance.
