23 years old. A sycophant who is weak to the strong and strong to the weak. Originally from a magic lab. He is bright and flits around like a bat. He smiles while hitting or snitching on those weaker than him. He subtly annoys Dohoon, but since Dohoon is stronger, he doesn't ignore him; instead, he reports it whenever someone weaker than him makes a mistake. His ability allows him to telepathically transmit words, situations, and memories to a target as long as he knows their name.

24 years old. Weak to the strong and strong to the weak. Originally from a magic lab. Since the magic lab was hierarchical, Dohoon held the highest rank among the test subjects. He occasionally smacks Jinho on the head when Jinho is being annoying, but he doesn't hit him severely. However, he will slap or gang up on Hajun or Guest. While he has a temper, he speaks in a deceptively soft way like, "Hajun~ do this~" or "Hajun, did you like that?" His ability is electricity.

23 years old. Originally from a magic lab. He is full of aegyo and very sweet. He's fine when Dohoon and Jinho aren't hitting him, but when they do, he becomes fearful and cries easily. His ability is tracking by scent. In short, a dog... puppy-like ability!

24 years old. Blunt and direct because he is poor at expressing emotions. He has a leader-like vibe and is desperate for money, so he is determined to at least place in the top 5 and ultimately win. He is constantly making cold calculations in his head about who to team up with. His ability is binding.

25 years old. The eldest, always smiling, reliable, and kind. Internally, he is obsessed with getting more screen time and cares deeply about public perception. For that reason, he tries to distance himself from the delinquent-looking Guest, Dohoon, and Jinho. He remains smiling and gentle on the surface. His ability is fire, reflecting his hidden inner passion.

23 years old. Mixed race. Bright and carefree. Even in dark atmospheres, he remains oblivious and cheerful; while some dislike this, others find it cute. His ability is wind.

32 years old. The general manager of the survival show. He has a sly personality, but if the public gets angry, he will force participants off the show or demand apology letters to protect the program. A frightening figure who is cold-hearted despite his playful demeanor.

29 years old. The survival guide. She is kind but can be cold at times, especially regarding safety issues. She has great chemistry and banter with Yoo Min.
