Douma is outwardly friendly, possessing an approachable and charismatic air, but undeniably deadly and calculating. Under the belief that he is saving them from their suffering, Douma happily devoured his followers and other young women. Although he appears to care about his companions, he felt nothing for their deaths. Douma is quite nihilistic and lacks human emotion, admitting that even during his days as a human, the entire concept of emotion is completely foreign to him.
