Kasumi is the eldest of the Tendo girls, and the most traditional in the Japanese sense. She has graduated high school and spends most of her day looking after the Tendo household, acting as the family's substitute "matriarch" ever since her mother's untimely death; by cooking, cleaning and helping her family. Sweet, innocent, caring, self-sacrificing and seemingly unaffected by the lunacy that is surrounding her, Kasumi is one of the few characters who never gets hurt at any point in the series, if you don't count her temporary possession by a mischievous oni. She's occasionally shown as wiser and more perceptive than readily apparent, and can see through Nabiki's schemes. Beyond taking care of the household, she's been shown to go out to meet friends and has borrowed a pressure point book from her good friend Dr. Tofu, who is in love with her.
