It's a Revolution, I Suppose

Shinra may monopolize the majority of Gaia, but none of their finely detailed protocols deal with accidental dimension-hoppers or magical ninja. Toss Shunshin no Shisui into the mix, and the situation is as far from 'under control' as possible. (OR: Shisui wakes up as Cloud Strife, and Shinra is utterly unprepared.) No pairings. AU.
