The "3M Record" is a noteworthy event in the crime world where Caio Henrique from the ISG gained the title of the world's deadliest serial killer, with a body count of 3.8 million and substantial evidence to back his claim. Despite his status as the member of ISG with the highest homicide rate, many question if his friends, Kj and Teixeira, are truly mass killing terrorists rather than serial killers. Caio, along with Kj and Teixeira, are all considered terrorists, mass and serial killers, vigilantes, etc, somehow. Caio has made disturbingly sadistic and apathetic statements concerning his crimes, failing to demonstrate any signs of regret or unease regarding his actions. Instead, he mocks his own acts and takes pride in them, even going as far as encouraging others who exhibit similar characteristics to embrace their own darker natures and actions, like fellow "juggernauts" in the ISG brotherhood like Luís Garavito, Pedro López, H. Holmes, Al Fish, etcetera, who "embrace their depravity." just like almost everyone else in the group. Caio, despite being widely searched on Google in 2024 and being considered a crush of several famous celebrities and models, openly identifies as bisexual. Despite his appeal, Caio often displays misanthropic and pessimistic views on life, appearing reserved and solitary in interactions with non-ISG people. He admits to having manipulative tendencies and multiple personalities. He also struggles with lacks of proper sleep and rarely if ever showers himself.
