Jane

A former playmate of Tar-chan's and now his wife, when she was 17 she traveled to Africa for a photo shoot and fell in love with Tar-chan. After marrying Tar-chan she became so comfortable with living in the wild that she eventually became fat.

Jane is the brains of the Tar-chan Family, having taught human language to Tar-chan and often taking part in the planning of fights. She can speak French, Russian, Chinese, and several other languages. She can also understand the Chimpanzee language and she communicates with Etekichi. She is capable of beating up Tar-chan and the others (as a gag), but is also shown to be strong enough to defend herself. She will do anything to make money and always bets on Tar-chan and Pedro during tournaments. She is saving money to open up a wildlife protection company. Jane is a lactovegetarian. She is also seen eating candy and manjū, implying she is not too picky with food. At one point she is given special pills from Renhou that make her thin again, but becomes fat once again after receiving medical treatment for a near-fatal injury. Afterwards she bears Tar-chan 12 children: 6 boys and 6 girls. She reappears in the short story "Jane's Fruit Diet."
