[Musician] Yellowy

Hansung Yu's test assistant on Evankhell's Floor. When dealing with Regulars, she always has a pleasant smile on her face. However, there is a surprising side to this businesslike lady. She is a performer in her time off. As soon as she finishes her work, she transforms from a test assistant to a musician, fully unleashing the talent she has been keeping bottled up all day. She always carries her signature microphone and can sometimes be seen humming when others are not around.
