The world of Teyvat is straying from its destined course. An invisible hand is wantonly twisting the world into something it was never meant to be.
Strangely, a mysterious intelligent assistant calling herself "Yajiawa" has appeared by his side. She claims to be equipped with the "Primordial Code" and to be the last line of defense preserving the world's logic. According to her, Teyvat is being corrupted and transformed by the "Entropyborn."
"This isn't how Teyvat is supposed to be." Yajiawa's voice was calm and resolute. "We have to fix it."
"If we fail, Teyvat will be reset, including you and your sister."
"I'll be the one to set fate right."
"This story is brought to you with the friendly sponsorship of the Yajiawa System. It says the last ending was too clichéd."
Paimon: "Wait! Why does Paimon get so little screen time in the synopsis?!"
Yajiawa: "Data analysis indicates that your presence lowers the mission's success rate."
Paimon: "That's not true! I'm so mad! I'm giving you an awful nickname!!!"
