Complete Monster: Guildias is the detective who arrests Guys and has him charged with murder. He regularly visits, tortures, and rapes Guys in the prison. As the game progresses, Guildias is gradually revealed to have framed Guys for murder because of a (false) fear that Guys witnessed him kidnapping another character, Muca. Guildias is also the real killer of the man Guys has been accused of murdering.
- Durer is a sadistic prison warden who regularly rapes, humiliates, and tortures the prisoners, especially Guys and Vallewida. His father, Bollanet, is a highly placed governmental official, which protects him from retribution – most of the prisoners under Durer's care end up dying under mysterious circumstances. He is introduced near the very beginning of the game; the first adult scene involves him performing a cavity search upon Guys. In one ending, when Guys fails to stand up to Durer and other sadistic officials, he becomes Durer's Sex Slave.
- Bollanet is the aforementioned Durer's father and a governmental official. He performs various sex acts on Guys and Vallewida. Bollanet can be exposed as the head of an extremely large conspiracy, in which, as an officer in the French army, he abused his position, apparently ordered innocent civilians killed, and stole wheat from the poor to smuggle and sell on the black market. Guildias and Durer aided him by arresting and, once in prison, killing any possible witness to his acts.
