Furofuki

Furofoki is a Konoha medical ninja examining Jofuku flower in Jofuku Forest on the mountain of the same name. When queried by Naruto about her decision to live and work all alone on the mountain, she told him that's what she decided and it wasn't his business. She has a great understanding of the flowers and seems to have gathered quite a few of them, indicating that she may have either fought off the flowers' defenses or discovered a way to safely harvest them, either one being testament to her ability.
