Catherine Astor is a character from the original net anime series Love Through a Prism. She is introduced as the aristocratic fiancée of Kit Church, a gifted and detached student at the prestigious Saint Thomas Art Academy in early 1900s London. As a member of what is implied to be a wealthy and traditional British family, Catherine is deeply entrenched in the social hierarchies of her time and place. Her background gives her a strong sense of pride in her noble bloodline, which she uses to assert her status over others. Personality-wise, Catherine is portrayed as sharp-tongued and passive-aggressive, often critiquing those she sees as beneath her while simultaneously hiding her own personal insecurities. This behavior is particularly evident in her interactions at the academy, where she navigates romantic rivalries and social competitions. Her primary motivation stems from her engagement to Kit, as she seeks to maintain her position as his betrothed and defend the exclusivity of her aristocratic circle. Within the story's narrative, Catherine serves as an initial antagonist and rival to the protagonist, Lili Ichijoin, a Japanese exchange student whose talent and growing closeness to Kit threaten the established social order. Her role is defined by her opposition to Lili, whom she mocks for her unconventional Eastern painting style, deeming it strange and unfashionable compared to Western techniques. Her key relationship is with Kit Church, to whom she is engaged, though the nature of their bond appears strained by his indifference and her jealousy. Her primary conflict is with Lili Ichijoin, whose sincerity and artistic ability challenge Catherine's sense of superiority and her claim to Kit's attention. While her full character development across the series is not detailed in available sources, her early actions demonstrate a clear arc of antagonism, as she uses her social influence and sharp wit to undermine a rival she perceives as a threat to her future. As a student at a prestigious art academy, Catherine possesses notable artistic abilities, specifically in oil painting, which is the focus of the school's curriculum. Her skills allow her to be a competitive peer within the rigorous academic environment. She also has an admiration for elegant fashion, with a particular appreciation for gowns such as the Silver Lily, reflecting her attention to aristocratic presentation and luxury.
