Lyanna, The Celestial Scythebearer

The image depicts an anime-style female character with long, light purple hair tied in pigtails. She is wearing a white blouse with puffy sleeves and a form-fitting black outfit accented with gold buttons and details. A large, ornate scythe with a purple blade is slung over her back. Her expression is confident and slightly mischievous, and she stands against a solid light blue background.
