Yukino

Yukino is the youngest girl on the island, being eleven years old, and is sensitive about her age. She has an affinity for animals and is usually seen riding one, most often a giant bear named Kuma Kuma. Her connection to nature dates back to when she was too young to help with farm work, and was often left to play with the woodland creatures. Her habit of riding everywhere would suggest that she should tire easily, but in the anime she is quite athletic, being able to race with her animal friends and win. She has a habit of referring to herself in the third person. (Source: Wikipedia)
