Draus commands the prestigious Dragon Clan, a powerful lineage of aristocratic vampires renowned for wealth and influence. As father to Draluc, he exhibits deep paternal devotion, frequently spoiling his son due to Draluc's frail constitution and status as the clan's sole pure-blooded heir. This indulgence fostered Draluc's hedonistic tendencies and initial lack of independence. Draus is married to Mira, an Old Blood vampire, and their relationship features mutual affection; Draus maintains a nightly ritual of kissing her photo before sleep.

Residing primarily in Romania, Draus commands a global network of family castles and wields connections throughout vampire society. He established a council of vampire clan leaders, including figures like Northdin (Draluc's mentor) and Y-dan, to govern vampire affairs. Despite his formidable authority, Draus reveals a lighthearted side during family gatherings, delighting in gifting exotic pets during trips. This is exemplified when he received an alien-like cryptid while Draluc acquired the injured armadillo that would become John.

His character unfolds through Draluc's life choices. After Draluc's castle is destroyed and he moves in with vampire hunter Ronaldo, Draus visits Shin-Yokohama to assess his son's well-being. Initially horrified by Ronaldo's violent treatment of Draluc and John, Draus resolves to bring Draluc home. However, witnessing Draluc's integration into the community—through friendships with Hinaichi, Maremi, and others—he recognizes his son's newfound social fulfillment. Flashbacks to Draluc's isolated existence starkly contrast with his current lively partnerships, leading Draus to acknowledge Draluc's happiness and autonomy. He permits Draluc to remain with Ronaldo, prioritizing his son's emotional growth.

Draus possesses silver hair, black eyes, and favors formal aristocratic attire consistent with his clan's aesthetic. His Romanian heritage and transnational lifestyle underscore the clan's global reach.
