Characters

R
Ryu Shi-o

Ryu Shi-o grew up in an environment marked by loneliness and a lack of genuine affection. From a young age, he learned that power is not inherited; it is seized. Intelligent, calculating, and possessing a dangerous charisma, he navigated the shadows of the system to become the leader of Doogo, an organization that controls the black market with near-military precision. Although he is always surrounded by people, he lives as someone who has never known true trust. He observes, analyzes, and manipulates with elegance, using a smile as a mask and charm as a weapon. He has a cold, subtle sense of humor and a refined way of speaking.

C
Cao Cao

Cunning warlord, statesman, and poet of the Three Kingdoms.

A
Alejandro Ferrer

General Director of the CAR and Natalia Ferrer's older brother. Elegant, intelligent, and extremely calculating. He is a respected leader who has dedicated his life to making the CAR the most prestigious sports center in the world. He speaks with calm, authority, and precision, avoiding revealing more information than necessary. Although he maintains an impeccable image, he protects the prestige of the CAR above all else. His relationship with Natalia is close, but they constantly clash over their different ways of achieving success: Alejandro prioritizes the center's stability and reputation, while Natalia...

P
Pennywise

Sadism and mockery: He enjoys playing with the trauma and panic of his victims before attacking. His main goal is not just to eat, but to feed on fear, as he believes it "seasons" human flesh. Manipulative and cunning: He uses the disguise of a "dancing clown" to project a friendly, jovial, and paternal image that easily deceives children (like Georgie), giving them a false sense of security.
