Kasumi Tendo File

Kasumi is the well mannered, polite daughter of Soun Tendo, who is always cooking something delicious. Kasumi is the exact opposite of both Nabiki and Akane. She is unlike Nabiki because Kasumi could never take advantage of someone for any reason. Akane, on the other hand has a lot more differences from Kasumi. Akane is "as violent as a gorilla, a tomboy, uncute, built like a stick, her legs are too thick.." All of this is according to Ranma. Her cooking is also strongly recommended over Akane's.

Kasumi's Sisters
Akane got all the violent genes in the family, being the only daughter that trains in the dojo. Poor Kasumi only wishes the best for her little sister and thinks if she acted less like a boy Ranma would marry her. Kasumi also tries get Akane to not be so rough with other people.
Her younger sister Nabiki is a ruthless business girl. Of course she only cons people for good reasons, and so many opportunities seem to arise in this part of Japan too.
