Hwa Ryun

''"As promised, everything we could possibly want, everything we desire is prepared up there." ''Hwa to Baam

Hwa Ryun is a Ranker of The Tower, and a Guide who was assigned to guide Rachel through the Tower. Evan Edrok seems to recognise her. She posed as a regular so she could guide Rachel without suspicion. She entered the tests on the Second Floor and teamed up with Yung Changsoo and Goon. She refused to ally with the other teams in the Crown Game, and wiped them all out until she was stopped by Androssi. She got past Androssi and attacked Lahel, and as a result was wounded severely in the face by Baam, not entirely purposefully though. She was then assigned the Wave Controller Position.

Throughout the story, she is thought to only have one eye, due to Baam's Shinsoo atacking her. She covered her face with a jeweled mask, until it was smashed by Baam, after which she only covered half her face. She fights using Shinsoo to enhance her strength and speed, and also uses a gold staff that can fly and attack using Shinsoo.

It ought to be noted that she encountered Evan, (a fellow Guide) who seemed surprised to see her, although they did not talk.

She appears to be heavily involved in the undeveloped conspiracy concerning Rachel. She congratulated her for killing Baam during the Submerged Fish Test, although she apparently knows Baam is still alive. She secretly left Rachel on her own, and is now helping Baam climb The Tower. She has been revealed to be a member of Baam's mysterious support group.
