The winner of the Squid Game that took place three years ago, Gi-hun has decided to re-enter in an attempt to figure out who is still running it after the death of game creator Oh Il-nam and take them down. Gi-hun has become consumed by his grief and trauma over being the sole survivor of the last games and has spent the past three years using the blood-money prize he earned (45.6 billion in South Korean won) to try to track down the games again.

The current head of the Squid Game, following the death of game creator Oh Il-nam at the end of Season 1. In-ho has been working for the games since winning them himself years ago, leading the pink masked guards while wearing his own all-black uniform.

Spoiler alert: This year, In-ho decides to follow in Oh Il-nam’s footsteps and enter the games as Player 001, in order to teach a lesson to Gi-hun upon his return to the game. Gi-hun, who only ever encountered the Front Man when he was masked, has no idea that In-ho, who goes by the name Young-il during the games, is the man in charge.

A police officer who infiltrated the Squid Game in Season 1 in hopes of finding his lost brother In-ho, who has been missing since he entered the games. At the end of Season 1, Jun-ho finds his brother, In-ho, but it turns out he is now the Front Man in charge of the game. In-ho shoots Jun-ho off the top of a cliff, seemingly letting him fall to his death. Jun-ho recovers and is working as a traffic cop at the start of Season 2.

Returning from Season 1, this man is in charge of going out and recruiting down-on-their-luck people to participate in the games.

He recruited Gi-hun in Season 1.

A woman who works in an amusement park after escaping from North Korea to South Korea and having been separated from her infant daughter in the process. She pays investigators to look for her daughter with her small salary, but then takes a job as one of the masked pink guards at the games in exchange for an offer of help to find her child. While working as a guard in the games, she attempts to help some of the players, including Player 246, who she recognizes as a former co-worker whose young daughter is sick with cancer.

Mr. Kim (above right) and Woo-seok (above left) are two of the men employed by Gi-hun to look for The Recruiter who brings people into the Squid Game. Mr. Kim is a former loan shark of Gi-hun’s who trusts that something about Gi-hun’s story regarding the games must be true because he was able to repay him an enormous debt three years ago. Mr. Kim is Woo-seok’s boss and friend, and Woo-seok becomes as invested in helping Gi-hun find the people behind the games.

A long-time friend and former coworker of Gi-hun’s who was last seen gambling alongside Gi-hun at

In an interview with TV Guide, “Squid Game” creator Hwang Dong-hyuk explained his decision for the casting choice: “In the beginning we were doing our research, and I was thinking of doing an authentic casting of a trans actor. When we researched in Korea, there are close to no actors that are openly trans, let alone openly gay, because unfortunately in the Korean society currently the LGBTQ community is rather still marginalized and more neglected, which is heartbreaking.”
