Born in the Land of Sand, her name means "eternal beautiful child". Her father was a merchant who traded with the Land of Water, where he met her mother. At a young age it was discovered she had a basic ability to use wind, unlike most of her village, who used earth. So after her basic ninja training, she set off on her own to learn to better control her abilities. She ended up in the Land of Water, where she met her mother (she was raised by her father not her mother). She stayed in the Land of Water for about 6 months, learning a couple water techniques from her mother in the meantime. Afterwords, she left to roam the world again. She eventually wandered into the Safari Country, where she was taken in by a clan of rabbits after saving one of their elders from being trampled by a zebra. The rabbits trained her during the 3 years she spent with them, giving her the ability to travel at extreme speeds, summon rabbits, and even master her control over wind. After learning what she could from the rabbits, she set off in search of adventure...
Overall, Kumiko is very quiet and kind, but after she gets to know you she can be a bit less peaceful.......
