Yuffie and Vincent
Here I will tell you how to get
secret characters Yuffie Kisaragi and Vincent Valentine.
Yuffie Kisaragi
Go to any forest in the world and
find and fight Yuffie or "Mystery Ninja". After you
beat her you'll find yourself in a place with a save point, don't
use the save point, and talk to her, then she will ask you a series
of questions. Answer the right ones and she will be under yourcommand
until Watui.
Y. Hey you spikey-headed jerk! One more time, let's go one more
time!
A. Not Interested.
Y. You're pretty scared of me, huh!?
A. ......petrified.
Y. I'm really gonna leave! REALLY!
A. Wait a second!
Y. You want me to go with you?
A. ......That's right.
Y. All right! I'll go with you!
A. ......Let's hurry on.
Vincent Valentine
Go to the Shinra Mansion in Nibelheim and go upstairs
to fight Lost Number inside the safe. To get in the safe, turn
the lock: Right 36, Left 10, Right 59, Right 97. You have less
than 30 seconds to do this. Beat the boss and get the key from
the safe, and go to the mansion basement. Go to the door-like
entrance and open the coffin to see Vincent. Talk to him about
your mission about Sephiroth and he'll return to sleep. Wake him
again and you'll be able to name him. He'll go to sleep again,
but when you walk out of the basement he will join the team.
