Detruire Zankoku

Note: This is an original character made by me, Not Luke, minus the artwork and other references.

Detruire Zankoku is an original/custom character made for the Demon Slayer verse. He lived his human life 500 years ago during the Sengoku Era (the Golden Age of Demon Slayers) but later turned into a demon. He is the creator of Singularity Breathing and is an ancestor of the one who made the Trou Noir AI system in the future.

Appearance
Detruire is a tall, somewhat muscular man with short black hair with a red streak on the left. Detruire's body is slimmer with his overall body shape being in the middle of feminine and masculine, though he only makes himself look life this to hide his strength. Det's Demon Slayer Mark is unique, as it appeared as a streak of red on the left side of his hair.

Detruire wears a tattered black shirt with white tattered ribbons flowing around his neck. He has a dark grey robe tied around his waist with a black belt and usually wears tattered black pants and shin guards, along with grey sandals. When attending a formal event, he wears a dark grey Yukata with a dark red belt that appears to be bloodstained.
