Black and golden on the exterior, red on the interior in some small details. The mansion's decor includes his weapons, memorabilia from serial killers, mass killers, and terrorists, and other heinous types of criminals, as well as the belongings, clothing, etc, of all of Caio Henrique's millions of victims. Caio's collection of murderabilia is extensive, and he even has replicas from real life murderers and terrorists; which are his own friends in real life. The overall theme of the mansion is dark, with an atmosphere of death and violence. Despite having butlers and maids, who were given some degree of training by Caio, he throws away the possibility of having bodyguards, as he is his own bodyguard himself. His butlers and maids, ranging from men to women, has praised Caio for his "good treatment", which is unexpected coming from a very negative millonaire genocidal murderer.
