Charles Brant is an oil painting professor at Saint Thomas Art Academy in the anime Love Through a Prism. He is the instructor who first receives Lili Ichijoin when she enrolls at the school, and he presides over the painting class attended by Lili, Kit Church, Dorothy Brown, and Peter Anthony. His teaching method centers on practical assignments and direct evaluation. On one occasion he instructs the students to paint the sky as it appears, and when the work is reviewed he places Kit first and Lili second. His assessment of Lili acknowledges her strong technical skills but compares her approach to that of a draftsman, revealing that he values expressive and personal artistry over flawless craftsmanship. Brant also extends practical help to his students beyond the studio. When Lili finds herself short of money, he provides her with paid work translating a book on ukiyo-e, an arrangement that allows her to remain at the academy. Within the story he functions as a mentor and a guardian of artistic standards, and his assignments and critiques influence the students' development and the competitive dynamics among them. He is a supporting character rather than a protagonist, and the narrative does not dwell on his personal history, private life, or inner conflicts. His notable abilities lie in his expertise in oil painting, his sharp eye for evaluating student work, and his capacity to push young artists toward a more personal and expressive style.
