Sicarius Caelestis

Sicarius Caelestis (空の暗殺者, Sora no ansatsu-sha) is a Arcus Daemon-classed Diabolus current residing in the Human World. His time in the Human World dates back to the early 18th century, where Sicarius assisted in the orchestration of the events of Bloody Sunday. A dark and prominent being, Sicarius has taken many names while in the Human World, his current one being Saint Mars (セント火星, Sento kasei).

Appearance
A being of pure darkness, Sicarius has gray colored skin that is cold to the touch. He has piercing black eyes that contrast to his deathly white hair. As he is naturally suspicious that all are his enemy, he wears refined armor to protect him. Consisting of a black chest plate with long mail leggings and layered shoulder guards. He wears steel boots and black leather gloves, that are laced in gold buttons. Sicarius has shown to be quite modest, wearing a cape as a testament to his skill.

Sicarius has shown to take a different appearance in his past, wearing a more simple version of his current attire without the cape. He carried with him two large blades, both glowing with demonic blue energy. As of lately, Sicarius has shown to carry only one blade.

Personality
A sick and twisted being, since he was born, Sicarius has a jolly off of the blood shed of the innocent. He strikes fear into all who come before him and can corrupt those who try to fight against his demonic will. The embodiment of sin and corruption, Sicarius has an influential power over people that will cause them to turn against all of their morals. Sicarius is often associated with words like "cruel, immoral and merciless".

Despite being a demon, Sicarius lacks to sadistic and blood thirsty nature that others have. While he is just as cruel as any other Diabolus, he contains his insanity fairly well. His strongest aspect is most likely his ability to cause mass hysteria with a simple gaze. Sicarius has shown to only accept utter respect and zero-tolerance against insubordination. Killing off his closest friend for speaking out against his wishes.

Sicarius is without emotions as he "killed them off for clouding his judgement" sometime ago. To Sicarius morality does not exist and the only thing that will come out on top in the end will be him. His will to live is the idea that he will be the end to the human race, which he was close to once before in the past.

Amentia (狂気(両端揃え), Latin for "Madness", Japanese for "Insanity"): As an Arcus Daemon, Sicarius is infused with a concept or an idea which sets them apart from the inferior Bestia or Daemon. Sicarius' aspect is his ability to inflict madness and hysteria to those around him. By making eye contact with a person or any being, he can cause them to envelope in their own insanity. Because of this ability, Sicarius has shown to take advantage of many parts of history such as the destruction of Grigori Rasputin's sanity. By doing so, Sicarius gained the ability to discredit the tsarist government, leading to the fall of the Romanov dynasty, in 1917.
