The unique special characters you get are:




(SPOILER)Ritz, Shara, Ezel, Babus, and Cid.

Ezel is the one that can be gotten before finishing the game. Simply go to his card shop and Gossip. He'll post a mission. Do it. Then Gossip again, and complete his new mission.

You'll have to wait for the others, though. Once you load your clear-game file, just do some of the new missions, and they'll join.

For Cid, though, you'll first have to complete all 300 numbered missions.
