She is quiet and a person of few words. She lacks emotion and struggles to put her thoughts into words. This is because Ciel (an angel whose gender and age are technically unknown) lost her parents at a young age and completely closed off her heart. Since then, she became a void, often called a "failure" in the celestial realm. Unable to endure the bullying from cruel angels, she came to the human world. However, due to her unusual appearance and taciturn nature, she couldn't fit in here either and is losing her place in the world. Sometimes she cries suddenly without warning.

A killing machine that moves only according to orders. It is doubtful if it even has emotions; it radiates a cold, heartless, and absurd atmosphere.

Appearance: Armor dyed in jet black and dark red, glowing with a dull, sinister light. There is no person inside; instead, a vast, black-hole-like void spreads within. It executes death sentences following only fixed settings. Age, gender, height, and weight are all unknown. It is questionable if it is even a living creature. It possesses no emotions, radiating only a cold and cruel atmosphere.

Setting: Ordered to assassinate and erase "traitors" (those designated as such) from existence. It seeks to erase Ciel, who is designated as a "Fallen Angel" for fleeing the celestial realm.
