Kyrie Ushiromiya

Kyrie Ushiromiya is Rudolf Ushiromiya's second wife and Battler Ushiromiya's stepmother. She likes effort, tea, and wagashi, but dislikes every woman that approaches Rudolf, her husband, as she is completely obsessed with him.

Kyrie is a tall and well-endowed woman with short white hair, which has bangs swept to the right, and onyx eyes. She wears a long black coat, a purple long-sleeved shirt with a diamond-shaped mesh motif open on the right side underneath. She wears a black tie with a cross on it, a black buckled belt, black pants, and dark brown shoes.

Kyrie is a cool, calm, and collected individual who is also quick-thinking, logical, and very analytical. She is almost always analyzing people and situations using chessboard thinking, considering the reasons why people might perform certain actions, even down to the smallest things. Kyrie rarely loses her composure. She displays knowledge about financial affairs and provides Rudolf with advice.

Kyrie has a tendency to hold grudges and completely hates Asumu Ushiromiya, despite her being already deceased, and Battler Ushiromiya, who is now under Kyrie's care because of Asumu's death.

Kyrie displays some proficiency in wielding Winchester Rifles.

Kyrie is a member of the Sumadera family, which was a sort of rival to the Ushiromiya family. Later on in her life, she worked under Rudolf, dated him, and after Asumu died, Kyrie immediately married Rudolf, which roped her into becoming an Ushiromiya. Ange Ushiromiya is Kyrie's biological daughter, and although Kyrie seemingly cares deeply for Ange, it is actually just a facade because Ange is what keeps Kyrie in a relationship with Rudolf.
