Five days have passed since the crown game. Rachel requests that Khun lie to Bam that she was never here, to prevent both of them becoming each other's burdens, although Khun quickly sees that she doesn't really care about Bam and works to distance the both of them, fulfilling Rachel's request in the process. Anaak steals the Black March, but it refuses to listen to her. After Bam reawakens, Khun tells him about how Lero Ro assigned them all positions in their teams to start the fourth test: Fisherman (Close quarter combat), Spear Bearer (Attacking from distance), Lighthouse Bearer (Illuminating the tower and information gathering), Scout (observe the enemy's movement and assist the Fisherman), and Wave Controller (support and control the battle with Shinsu). Bam receives the Wave Controller position, a position that utilizes Shinsu to support team members. In order for Shinsu to be used above limits, contracts must be formed with the floor masters using their Pockets, but Bam is warned by the floor bearers that receiving the contract will only shackle him. Everyone works hard in order to pass in their classes. During mealtimes, Bam meets Endrosi Jahad, a Princess of Jahad in her own right who labels Anaak as an impostor. Khun later finds out that even though Anaak was supposedly made a Princess of Jahad after climbing the tower, she is currently in the midst of passing the tower's tests and records claim her to be deceased. As an enraged Anaak and Endrosi battle in their class, the current Anaak is revealed to be the real Princess's daughter whose parents were killed by the other Princesses, prompting her to enter the tower for revenge.
