DON CORNEO'S MANSION
From the moment you meet him, he reeks of comic relief. Dressed in outlandish hues of bizarre rainbow colors and sporting a not-too-trendy mohawk hairstyle, one can hardly see how this man, of all men, should be running Wall Market's prostitution ring. Not to mention he's giganticly fat and short.
Perhaps that's part of the disguise, because he does actually keep a sizable private army of lackeys milling about to do his dirty work, and that's part of the reason he rules Wall Market with an iron fist. In fact, every new girl that enters the Wall Market has to appear before the Don, and entertain him...uhh privately.
During the game, Cloud and Aeris spot Tifa in this area and so they quickly run after her. You learn that she is interviewing with Don Corneo, the horny pimp man himself. He likes to have a woman with him every night so he interviews three at a time. Cloud has to dress up like a woman in order to get into the mansion (I love this part). Afterwards, as Cloud,
you find Tifa inside the basement. Tifa explains that she is there strictly for information because Mr. Corneo seems to be connected with Shinra and might know something about sector 7. Corneo takes Tifa into his bedroom for something very predictable but luckily she is rescued by Cloud. I'm sure Tifa would have been able to take care of herself anyway but
Cloud is always there to save the day. There are many different things that you can do to get Aeris or Cloud picked by the Don, but the simple way to get Tifa is by going to the dress shop after you learn where she is. The woman there will tell you need to find her father first, he is located in the bar. Then you have to go get in a wig by participating in a squatting competition in the gym.
