Uhh, putting it simply: There are people out there that identify as extensions, reincarnations, or literal embodiments of fictional characters. The FF7 House case was a group of such people within the FF7 fandom, each identifying as assorted characters from the game, headed and brainwashed by an exceedingly crazy lady that identified as Jenova.
They moved in together, this Jenova girl used everyone for their money and other such things, and insanity ensued. THIS WEBSITE HERE is a collaborative account by escapees from this deranged household.

Apparently this "Jenova" lady is still at it, too. Just in a different fandom. Which is disappointing for me, you'd think that all this would be undeniable evidence to get her arrested and her subjects given the psychiatric care they desperately need.
