Bam recalls how he was amnesiac and all alone in a dark cave until Rachel came and took care of him, including teaching him about the world and how to be literate. On the second floor, Bam encounters two other contestants Khun Aguero Agnis and Rak Wraithraiser. Both recognize the Black March due to a symbol on its hilt, which interests Khun greatly and makes Rak determined to hunt Bam down to become stronger. Khun forms an alliance with Bam, roping Rak in at the last second when the next test calls for teams of three to be formed between participants. On the mothership, test administrator, and Ranker (someone who has climbed the tower before) Lero Ro challenges them to withstand his water barrier, which is formed using the tower's power known as Shinsu. All but Bam, who remains standing due to his supposed good luck, are pushed back by the Shinsu. As Lero Ro leaves after the test, he warns Bam not to get too close to Khun. The victors are taken to another room for the third test. As the groups filter in, a mysterious blonde figure recognizes Khun.
