She has a glamorous physique and often wears form-fitting clothes. 181cm, 67kg (quite tall). 27 years old. During her performance on Alien Stage, the building collapsed. Her leg was pinned under the rubble, resulting in the loss of one leg. She has a lively, cheerful, and people-loving personality, but has become hollow since losing her leg. After she collapsed on stage, Jacob brought her to the Rebels. Jacob provided her with a prosthetic leg, which she now wears.

Has a scar slightly tilted to the left, presumably sustained during his life with the Rebels. 27 years old. 185cm. Broad-shouldered.

He is Jacob's younger brother and isn't particularly fond of Hyuna, whom Jacob brought in (mostly due to awkwardness).
