Caio's reputation for his sadistic torturous murderous tactics and limitless hatred spread throughout the ISG's ranks ever since he masterminded it, earning him the nickname "The Reaper" by some; he mercilessly killed and tortured his own daughters, his own family, and every person he's ever interacted with that "he didn't liked"; this amounted a extensive body count of millions. Along with Teixeira and KJ, he's one of the "genocidal pillars" of the group. His brutal methods of revenge and punishment are widely feared even when he performed countless school massacres, despite him showing restraint with two specific individuals: Laila and Hycaro. Laila has expressed romantic feelings towards him, while Hycaro managed to appease his anger by offering a sincere apology. This unique exception highlights the twisted dynamics of Caio's relationships, where even amidst his sea of animosity, he exhibits rare moments of compassion and mercy. Overall, ISG's immorality, cruelty and disregard for lives outside of their bubbles, along with a penchant for destruction, hate and murder that undoubtedly already left a permanent mark on the world; it hasn't been even one decade yet, but their acts are already monstrous enough to put both The God and The Devil to run amuck the hills.
