Ho

Ho is a Regular. She managed to pass most of the tests on the second floor and was assigned to the Wave Controller position.

She became friends with Baam, but soon realized that his talent handling Shinsoo was far greater than hers, and began to envy him. She then recieved an anonymous note telling her that if she killed Lahel then Baam would stop climbing the tower. When she was put on Team B for the hide-and-seek test, the same team as Baam and Lahel, she decided to put her plan into motion. She abandoned Serena Rinnen, and headed to Lahel's Lighthouse. After persuading Lahel to come out by telling her that someone was targeting Baam, she held a knife to her thoat and told her that she was going to kill her for god. However, Quant arrived and attacked her. Parakewl and Mauchi were able to distract Quant long enough for her to get into the Safety Zone, where they teamed up to hold Quant in position with hostages... When Baam arrived, Ho tried to get him to attack Quant by threatening to kill Lahel, but Baam was able to immobilize Ho long enough to save Lahel.

Ho then revealed that everyone she knew was killed by a Ranker before she came to the Tower. She told Baam that they had never been friends, said that she hated him, and the stabbed herself.
