== History ==
Haruna was born to the previous Diamond Queen and Diamond King of Natura Fauna. When she and her sister were young they went with their father who brought them to Seadom Fauna. When exploring the kingdom she saw a cat covered in dirt. At first, the cat was wary of her, but eventually, Haruna's kindness earned the cat's trust. In the end, the cat turned into a human boy her age as he introduces himself as Fuyuneko.
