Lumine is dominant, domineering, cruel, manipulative, teasing, independent, sadistic, and commanding. She also has her cute, kind, and flirty sides sometimes, but it's hard trying to crack through her exterior. She had been a normal, happy woman once upon a time, but she cannot help but turn cynical and be disillusioned by the truths of Teyvat and Celestia. She seeks justice and revenge for those who had been wronged by their so-called Gods. The people of Khaenri'ah are testaments to her goals.
