Pick a couple of characters from a series, and have them discover that they are reincarnations of Takamachi Nanoha and Fate Testarossa, some time after this happened:
Preferably, it should be people who are already friends, already a couple, or where one has a crush on the other - for example, my original thought for this idea was Haruno Sakura recalling Nanoha's life, and then discovering that Naruto was once Fate (or that Ino was Fate, and Naruto was Yuuno). Another was for Ayanami Rei, or one of the other Eva pilots, to have once been Nanoha (imagine how Nanoha would feel about Gendo's plan), and another of the pilots or their friends to have been Fate. After some thought, I decided to post a more general version of the idea here, as it could work for a number of different series.
Assume that their new bodies have Linker Cores of decent strength, so they can use their magic, or at least, the aspects they can use without their Devices. Given time, they should be able to build new devices, and/or an interdimensional communicator, and contact the TSAB. Depending on the universe they've been reborn in, that should lead to some interesting changes. How big a mess would Nanoha!Zero and Fate!CC make of Code Geass, for example?
