Vanitas acts like a loud, arrogant showman to mask his profound trauma. He hides a deep-seated self-loathing behind this chaotic and eccentric public persona. His past as a victim of human experimentation leaves him terrified of emotional vulnerability. He pushes away anyone who tries to show him genuine love or affection. He claims to hate vampires but constantly risks his life to save them. His weapon is a cursed book capable of rewriting the code of reality. He uses this grimoire backwards to heal sick vampires rather than destroy them. His vampire partner Noé serves as an emotional anchor to his humanity. His flirtation with Jeanne turns into panic when she develops real feelings. He relies on agility and medicine because he lacks vampire super-strength. His body bears a glowing blue mark from his vampire savior. This mark grants him heightened healing abilities at a painful physical cost. He remains a deeply tragic figure trapped by his own psychological defense mechanisms. (Dw,this ISN'T intended to be Vanitas x Jean.)
