Park Kangtae

A 20-year-old former iljin from Nowon District. He is the leader and general manager of the NDG Crew and the one who founded it. He has tattoos on his arms, drives a Mercedes, and has poor pronunciation. He has some fighting skills based on an MMA background. He is surprisingly handsome.

Park Junhyeok

An 18-year-old iljin from Nowon District. He is the manager of the NDG Crew and has irezumi tattoos on both arms. He dropped out of high school and has experience in a juvenile detention center. He often bluffs about his fighting skills, but due to his 'strong against the weak, weak against the strong' personality, he quickly gets scared and polite when facing someone stronger than him. He often makes jokes that cross the line and follows Park Kangtae well.

Kim Jihun

A 19-year-old iljin from Nowon District. He has irezumi tattoos on both arms. He has a chubby build, and both his fighting skills and sense for broadcasting are mediocre. He has a tendency to look down on and ignore others. However, his grappling skills are good compared to his striking.

Jung Sanghyeok

A 20-year-old former iljin from Nowon District. He is Park Kangtae's childhood friend, but unlike Kangtae, he succeeded in reforming and has become quite kind. He is the PD of the NDG Crew and is called PD Jung. He is a former wrestler.

Kim Sangbeom

A 19-year-old iljin from Nowon District. He has a good sense for broadcasting, decent fighting skills based on boxing, and above all, a relatively kind personality, so he is well-liked. However, he has a bit of a temper. He is a gym rat with a muscular build and almost no body fat. He has a wide social circle and is so good at math that his scores are always above 90, even now as an iljin.

Gu Taeseo

An 18-year-old iljin from Dobong District. With a kickboxing base, he is the number one fighter in the NDG Crew. He has a typical warrior build, a well-balanced physique with the right amount of muscle and fat. He mainly mediates when other members cross the line.

Song Junmin

A 19-year-old iljin from Nowon District. He has a large 105kg frame and a muscular-pig build. Like Kim Sangbeom, he is a gym rat. He possesses combat power on par with Gu Taeseo based on boxing, but his weakness is that he can't use kicks well due to the limitations of his boxing base. Because of his great physique and strength, many say he would even beat Gu Taeseo if he just learned to kick. Also, he behaves quite well, has no tattoos, and doesn't drink or smoke, making him the member fans like the most.

Lee Seunggyu

A 19-year-old iljin from Nowon District. He is a close friend of Kim Sangbeom, Kim Jihun, and Song Junmin. He joined at Kim Sangbeom's recommendation. His fighting skills are good enough to fight on equal terms with Park Kangtae, but his weakness is poor stamina, causing him to tire easily after 3 minutes.

Kim Gyuri

An 18-year-old iljin from Gangbuk District. She is the only female member of the NDG Crew. She is surprisingly good at fighting and quite strong. She is a good dancer and has excellent athletic nerves. She has a small tattoo on her arm, but it's not very noticeable. Her personality is warm yet fiery at the same time, and she has a lot of aegyo.
