The girl was an accidental creation of lightning, yet shared the same origin as the gods of Inazuma. She became the younger sister of Raiden Ei and Raiden Makoto, and was named Raiden Xi. Ever since she was little, Raiden Xi had longed to see the world beyond, so when she grew older, she traveled far and wide, searching for a way to save Inazuma. Along the way, she made many friends and became a dear companion to them. But just as things were starting to get better, the Khaenri'ah war forced Raiden Xi to return to Inazuma to protect its people. In the end, she died in battle... Fortunately, Raiden Xi was reborn in the real world on Blue Star as Xu Mengxi, a girl who had just turned eighteen. By chance, the game Genshin Impact came out, and while playing it, Xu Mengxi unexpectedly grew fond of the protagonist Lumine, Raiden Ei, Raiden Makoto, and others. But one day, after an argument, Xu Mengxi ran out of the house. Distracted and distraught, she was struck and killed by a driver while crossing the road. Xu Mengxi then transmigrated from the real world into Genshin Impact once more, gaining System 001. By then, a very, very long time had passed in Teyvat... Yet as soon as Xu Mengxi arrived, she found herself falling from the sky and crashing into Lumine. As time went on, she realized that she had come to Teyvat more than once. The System required Xu Mengxi to write down the deeds of the saviors she encountered on her travels. They were, of course, all the same person. As she wrote, her memories gradually returned. So what kind of story awaits Xu Mengxi now that she has returned to Teyvat? It’s only a matter of time before her memories come back, and before long, Xu Mengxi will face her future.
