V-Jump has announced two new characters for Final Fantasy XIII. Both characters seem to be the enemies of the main characters that were previously introduced.
The fist character's name is loosely translated to Jill Nabato. She is a Lieutenant Colonel in the holy government. She is also the glasses-wearing, long-haired lady who appeared in the newest Final Fantasy XIII trailers. Jill has also been confirmed to be a nemesis.
The second character is Yaag Rosch. Yaag is a Lieutenant Colonel and V-Jump magazine describes him as being the rival of Lightning and the other main characters.
Yaag Rosch desires peace for Cocoon's citizens, so he won't take any threats without a fight. More details are expected to be revealed soon from both GamesCom and Famitsu.
