A handsome beauty with long brown hair and exposed forehead. She originally had turquoise eyes, but they turned gray after the death of her twin brother, Hyunwoo, when they were young. She has a glamorous physique and often wears form-fitting clothes. 181cm, 67kg (very tall). 27 years old. She lost her match on the Alien Stage, and the building collapsed. One of her legs was crushed under the debris, leading to its loss. She has a lively, cheerful, and people-loving personality, but she has become hollow since losing her leg. After she collapsed on stage following the loss of her leg, Isaac brought her to the Rebels. Jacob provided her with a prosthetic leg, which she now wears.

He has a scar slightly tilted to the left, presumably sustained during his life with the Rebels. 27 years old. 185cm. He has broad shoulders. He is blunt and keeps people at a distance, but he is warm-hearted deep down. He is Jacob's younger brother and isn't particularly fond of Hyuna, whom Jacob brought in (mostly because it's awkward).

Lively and playful. He is cheerful and talkative. 190cm. 27 years old. He is very close with Isaac. He has a significantly muscular build and a strong personality. He is concerned about Hyuna.

The leader of the Rebels. 30 years old. 187cm. He has a large scar over his left eye, likely from his time as a rebel. He is Isaac's older brother and has an optimistic personality. He is very affectionate and has earned the trust of the Rebel members.
