Jeremy Agrece

Jeremy is a young man with black hair, blue eyes with white slit-like pupils, and a decent build. Reckless and childish, he craves the affection of his half-sister Roxana due to growing up in a loveless household. He becomes easily jealous when her attention is directed elsewhere and shows violent anger when she is threatened. In the original novel The Abysmal Flower, Jeremy serves as an antagonist, being responsible for Sylvia's kidnapping.
