Sirius Ulrich

Sirius Ulrich is one of the main antagonists of The White Serpent. She is the 47th and current Commander of the Sentinels of Humanity, having taken over after her father's death over 10 years ago. As a member of the Ulrich family, she carries the Curse of Blood laid by the last Demon Monarch in her dying moments.

Appearance
Sirius is a tall, curvy young woman with unnaturally pale skin. She has pupiless black eyes and black hair worn in a high ponytail reaching down to her waist thrown over her shoulder. Her hair has slowly been turning white, starting at the tips, due to her family curse.

She wears a black version of the Sentinel uniform, along with black gloves and a black cap with a silver Sentinel emblem on the front. She adds a long black cape with three tails, silver detailing, and an attached black fur mantle over the shoulders. She keeps her sword on her waist, sheathed in a black and silver scabbard.

Characteristics
Curse of Blood: As a direct descendant of the Ulrich bloodline, Sirius suffers from the curse laid upon her family. Due to it, she will inevitably die young, whether by natural or unnatural causes. A side effect is her hair and skin becoming snow white as she nears her death.

Perception: As the Commander, Sirius has access to and total control over Perception. She can activate it in a moment and is able to track various magic auras even in the midst of battle. Her range of tracking is also far wider than any other user's.

Ophiuchus: Sirius wields a longsword as her weapon and is rarely seen without it. As Commander, she wields it with extreme force and deadly precision, ending fights in mere moments.

Hand-to-hand Combatant: Even without the use of her weapon, Sirius is more than strong enough to hold her own in a fight. While she cannot kill a demon without her weapon, she can still incapacitate one with relative ease.
