Honkai: My Name Really Isn't Kiana

(The protagonist is a Kiana-version Durandal.) Asiya is a silver-haired beauty who longs for a peaceful life. After moving to Tianqiong City, she lived an ordinary, uneventful life, until the Herrscher of the Void awakened and everything seemed to change. One night, Asiya ran into a girl who looked exactly like her. The girl tearfully apologized and said things Asiya couldn't understand, like how she was just an impostor and Asiya was the real Kiana. Asiya didn't think much of it at first. But after an accident led her to meet a woman named Cecilia, who claimed to be her mother and said she wanted to make it up to her, Asiya finally caught on. Wait, could her name really be Kiana?
