Shirona is a League master and the Champion of the Sinnoh region in Pokémon Diamond and Pearl and Pokémon Platinum. Other than the player using a female character, she is the first known female Pokémon League champion in the video game series. Her japanese name means "Chosen by the gods"
She has blond hair and wears black clothing. She also has two hair clips that resemble Lucario's Aura Sensors somewhat, but with a yellow stripe instead of being all black. Shirona is from Celestic Town in the Sinnoh region. Apparently she made the training of Professor Rowan when she was young.

Quote from the Final Battle
"One look at you tells me many things about you. Together, you and your Pokémon overcame all the challenges you faced, however difficult. It means that you've triumphed over any personal weaknesses, too. The power you learned... I can feel it emanating from you. That's enough talking. Let's get on with why you're here. I, Cynthia, accept your challenge as the Pokémon League Champion! There won't be any letup from me!"
