Caio Henrique, a.k.a. "Red Eyes", stands as a ISG icon and the deadliest serial killer and torturer in both the world and Brazil. He has taken an uncountable number of lives through acts of murder and torture. His crimes include killing his own family, "friends", and others who were considered innocent. Additionally, he is also known to lack hygienic habits, and he has tracked down and killed other criminals around the world as well. With the supergroups and their unstoppable rampages, their presences looms like shadows over society, evoking fear and disdain. The ISG embodies the cosmic duality of sex and violence, pleasure and hate—an unholy equilibrium where extremes meet. Their actions blur lines between ecstasy and brutality.
