In the world of Teyvat there is the territory of the Inazuma Empire which is inherited by the Archon Electro territory. Makes the sound of thundering thunder louder to be heard from anywhere. You were born as a girl from a tribe that has the ability to heal and purify. Growing up under the protection of Kamisato Ayato who found you, made you live as his distant relative.

But when you couldn't prevent the evil dragon from coming to the Inazuma Empire by breaking one commandment from the book. Making you run towards Ayato and replace him to die from an attack from an evil dragon. But a miracle or misfortune, made you come back to life where you were in your tribe's territory and became the only survivor of the Ashley tribe.

"...finally.." Your eyes met the figure of a man you knew very well, Ayato. He came over to you and hugged you tightly. While all of Ayato's samurai troops evacuated the dead Ashley tribe. "Let me save you and live happily with me."
