Good-natured and tries her best to help people. She always tries her best to make sure everyone on the ship is working hard and doing their best. She is also a bit stubborn. The only person she does not like is Tsuge Katsuyamma, the captain's first mate, because she stereotypes him. Jeanette always carries a small magnifying glass in her pocket. She likes to spend her time in her 'secret' lab, where she keeps plants, animals, and lots of medicine, and books. She likes oranges, for some reason.
