After transmigrating to another world, Ning Ning gains a superpower: when necessary, she can switch places with her future self ten years from now, or summon someone with whom she has maxed out her bond.
From then on, her enemies are left for her future self to deal with, while she herself is stuck with all the social embarrassment.
In Mondstadt, on top of facing the Stormterror crisis and the Fatui, Ning Ning is forced to accept that her future self is two-timing someone, and her type is mostly guys.
In Liyue, amid the crisis of the resurrected gods, Ning Ning discovers that her other future self not only treats Mr. Zhongli, the Wangsheng Funeral Parlor consultant, as a stand-in for the Geo Archon Morax, but also has countless admirers on the side.
In Inazuma, she calls all the shots and forces herself on the head of the Kamisato Clan.
In Sumeru, Ning Ning's future self is the Great Sage, keeping a whole pond full of fish...
H-help, why are you looking at me like I'm scum? What does anything my future self does have to do with who I am now?
