Daan is a smart and inquisitive man who uses his medical knowledge and experience with the occult to help make sense of the world around him. He is fairly independent, quickly setting off on his own to investigate Prehevil. However, he is happy to help others when the need arises, such as when he offers to mix drinks for contestants in PRHVL Bop. Daan can be found caring for the townspeople when not playing as him, and he is often polite and even caring towards the other contestants.
