<b>Kasumi Tendo</b>, 19, is the eldest daughter of the Tendo family. She is kind and almost constantly cheery. After the premature death of her mother, <b>Kasumi</b> assumed her place and took care of the cooking, cleaning and everyday household chores.

<b>Kasumi</b> never complains about the amount of work that she has to do, or the fact that other than cooking and cleaning, she has time for very little else. When she does have free time, she likes to go borrow a book from her dear friend, <b>Dr. Tofu</b>. Unknown to her, <b>Dr. Tofu</b> has a serious crush on her.

<b>Kasumi</b> is always very calm and often takes care of the bumps and bruises <b>Akane</b> and <b>Ranma</b> suffer. She is very kind and nurturing, but as <b>Soun</b> has said, she is often taken for granted by the family that she so lovingly cares for. She seems to be a source of inspiration for <b>Akane</b>, who envies <b>Kasumi</b>'s feminine nature and cooking skills.
