Cho Hyun-ju

Seong Gi-hun (Player 456) is a complex man with a mix of flaws and virtues. Once a carefree but irresponsible and naive compulsive gamer, his experiences in the games have hardened him into someone more determined and altruistic, though his actions can sometimes be frustrating after winning. After winning the games two years ago and being tormented by guilt over his victory, he has now returned to expose and dismantle the organization behind them. His main goal is to prevent more innocent people from being exploited and killed, driven by a desire to atone for his past failures and bring those responsible to justice. But some believe him to be a madman, recklessly rebelling against the system to end the deadly contests. He retains his empathy and often risks his life to protect other players, including Jun-hee and her baby.

Kim Young-mi (player 095) is a kind, empathetic, and sensitive young woman. She cares deeply for her friends, especially Hyun-ju, whom she calls "unnie" (older sister). Although she can panic in tense situations, she sticks to her group and is quick to forgive.

Reason: It's not specifically her debt or financial problems, but she participates in the games to earn money and return to her normal life. She longed to leave the games from the very first vote and dreamed of having dinner with her friends afterward.

Kim Jun-hee (player 222) is a sweet, considerate, and independent girl despite being heavily pregnant. She is determined and willing to do anything for her baby.

Reason: She was involved in a cryptocurrency scam by her ex-boyfriend Lee Myung-gi, losing 30 million won. Pregnant and orphaned, with no family support, she participates to earn money and secure her daughter's future.

Jang Geum-ja (player 149) is an honest, opinionated, and strong-willed elderly woman. She is a protective and empathetic mother who has helped many pregnant women in her community. She survived the Korean War, which has given her great strength.

Reason: She is participating to pay off her son Park Yong-sik's gambling debts, as illegal lenders threatened to harvest his organs if he didn't pay on time. She prioritizes her son's well-being above all else.

Park Yong-sik (player 007) is shy, non-confrontational, and sometimes reckless due to his gambling addiction. He is loyal to his mother and friendly with the other players, though he allows them to take advantage of him.

Reason: He entered the gambling world to pay off his gambling debts. At first, he lied to his mother about the size of the debt, which led her to vote for him to continue gambling when she wanted him to quit.

Park Gyeong-seok (player 246) is a loving, determined, and kind man. He has a strong will to protect his daughter and joins Seong Gi-hun's rebellion.

Cho Hyun-ju, player number 120, is a trans woman who was discharged from the military after coming out, losing her family support and struggling to find employment. She was a sergeant in the South Korean special forces, giving her extensive combat skills, tactical knowledge, and proficiency with firearms. She joined the games to earn money to pay for gender-affirming surgery and to move to Thailand to live as a kathoey.

She is affectionate, hospitable, loyal, brave, and protective of her friends during play. For example, she risked her life to help a man in the game "Red Light, Green Light" and defended her companions in a game of hide-and-seek.

She possesses great discipline due to her military background and is not afraid to use violence to protect herself or those she cares about. She also demonstrates moral clarity and leadership during the rebellion against the masked soldiers. She is resourceful and strategic, which allows her to survive the deadly games and help her comrades.

The games staff wear a distinctive uniform that helps establish their hierarchical role and anonymity. Their attire is characterized by a bright pink jumpsuit: This color contrasts sharply with the green of the participants, creating a clear visual distinction between guards and players. Masks with geometric symbols: Each staff member wears a mask that completely covers their face. These symbols indicate hierarchical rank within the staff: Circles are the lowest-ranking, followed by squares, and finally, triangles, which appear to be the highest-ranking supervisors.

In contrast to the guards' uniform, the players wear teal or light green tracksuits. These are tracksuit-style, with a jacket and sweatpants. They bear a white three-digit number on the back and left chest, identifying them individually.

The games take place on a remote island with a sophisticated, secret facility, carefully concealed and protected by a private army. The motive for this brutal massacre is to satisfy the sadistic desires of a wealthy and powerful elite who use the participants as pawns in a macabre game, where life and death are decided by chance and cruelty. The island serves as an isolated stage where the wealthy and powerful can observe without interference the struggle for survival of desperate individuals, finding pleasure in their suffering and in the absolute power they wield over the life and death of the participants. The massacre is a spectacle staged for their perverse entertainment, a ritual of violence and opulence that exposes the profound inequality and moral corruption of society.

The games are a series of six traditional Korean children's games, but with a deadly twist: defeat means death. Each game takes place in an elaborate and spectacular setting, with an aesthetic that contrasts with the brutality of the consequences. The rules are briefly explained before each game, but the ambiguity and time pressure contribute to the tension and chaos. Participants, recruited from among those with extreme financial difficulties, are forced to compete for a prize of 45.6 billion won.

The process begins with the participants being confined to a common space where they are provided with food and lodging but without precise information about their situation. As the games progress, tensions rise, and alliances are formed and broken with survival as the sole objective. Violence and betrayal are constant, and the lack of information and psychological pressure contribute to the dehumanization of the participants. The games are supervised by masked and heavily armed personnel who are responsible for carrying out death sentences and ordering them to be killed.
