Yin

Meet Yin, a member of Hei's unique squad, known as a "Doll" for her emotionless vibe. This spirit medium has a cool ability to track and observe through water—pretty eerie, right? Huang jokingly points out that her "program" doesn’t let her feel or make choices, but she flips the script by choosing to stick around with Hei and the crew instead of bailing. There's a hint of her humanity peeking through! Originally named Kirsi, Yin hails from Finland and once studied with a famous pianist, Eelis, who developed a bit of a crush on her mom after her dad's tragic plane crash.
