From the introduction:
Welcome to Midgar, home to the cast of Final Fantasy 7, but not quite the same ones that you know and love. This is a much more perverse world based on several very lewd stories written by Damonisa, where the heroines have to fend for themselves in Midgar’s dark underbelly and often don’t quite manage it. Our heroine today is the lovely Tifa Lockhart, who’s just joined the Avalanche terrorist cell and finds it in rather dire straits. Avalanche is starting from nothing, with no outside support, no competent leadership, and no resources outside of a run-down bar. There’s also no sign of Cloud showing up to save her any time soon so Tifa’s going to have to do almost all of the heavy lifting all by herself if Avalanche is going to save the Planet from Shinra. But the odds are stacked rather heavily against her: between Tifa’s inexperience and naivete and the devious machinations of Shinra agents and crime bosses like Don Corneo it seems much more likely that she and the other heroines will only come to some sort of bad ending.
