She is a Japanese pony, who runs and owns her own Japanese themed restaurant, with her sister :3
She and her sister were born in a small fishing village, where her parents taught her how to capture and cook fish. One day during a really bad drought, she ventured out of her village, and went out to a bunch of different lakes to get enough fish to help feed the whole village, earning her her cutie mark. As of now she runs herself a very successful Japanese restaurant, in Canterlot, with her sister.
She is very brash and tomboyish, and she is often very easy to get annoyed, but she does care about providing for others, and she does take good pride in her restaurant and her cooking.
