Kasumi Sumadera

Kasumi is the daughter of the struggling Sumadera family, and Kyrie's younger sister. Since Kyrie was the original heiress to the Sumadera family, Kasumi spent her life like a very spoiled princess. But since Kyrie cut all ties to her family when she married into the Ushiromiya family, Kasumi was forced to take up the responsibility as the Sumadera heiress. Kasumi thus blames Kyrie for all the pressures she must now face, and loathes everything about her, including her daughter Ange. She is much more open and charitable than Kyrie, though not even that can mask her malicious envy.
