Rachel goes by two names—Rachel (라헬) and Michelle Light (미쉘 라이트)—and is basically Bam's only real friend. She's the one person who actually bothered to visit him in his cave, which already says something about their bond. Her big thing is wanting to see the stars; it's tied to this fear of the dark she's got, and she sees reaching the top of the Tower as her way to finally make that happen. The stars are supposedly one of those legendary rewards waiting up there.
