Tomas, once a member of the Magic Law Association, defected to join the clandestine organization Ark. He sports gray hair trimmed to his ears, piercing black eyes, and jagged, sharpened teeth, often shrouded in a black hooded cloak. His demeanor blends ruthless cunning with sadistic tendencies, fueled by an obsessive compulsion to hoard objects of beauty through a demonic pact granting access to a pocket dimension. This fixation drove him to criminal acts even prior to dabbling in forbidden magic, a descent unnoticed by his closest ally, Page Klaus, until Tomas’s instability erupted.

Within Ark, Tomas focused his malice on Daranimaru Goryo, a rival executor, subjecting him to forbidden rituals that nearly transformed Goryo into a half-gast—a trauma that catalyzed the latter’s redemption. Tomas specializes in psychological manipulation, dismantling adversaries by weaponizing their deepest vulnerabilities.

His past reveals a pattern of targeting magical law enforcers, orchestrating schemes to dismantle rival factions and inflict lasting physical and mental scars. Though aligned with Ark, his actions are rooted not in ideology but a warped aesthetic obsession, prioritizing the acquisition of beauty over the organization’s broader ambitions.
