Vanitas seems to take nothing seriously, and almost always has a playful grin on his face. He acts impulsively most of the time. Vanitas carries a mischievous air. Beneath his flippant attitude, Vanitas is a broken man who despises both humans and vampires, but hates himself more than either. Vanitas hates being vulnerable around people. He is self-deprecating and not understanding of love. He knows when to be serious, however, and will instantly switch gears if he senses danger.
