Here's a small character update thanks to 1up's translation of the latest of Famitsu's Final Fantasy XIII features. It turns out we were right to be cautious about our previous translation of the long haired antagonist's name. Jill Nabato, the commander of PSICOM, has now been confirmed to be named Jihl Nabaat and we also have some new background information on her and Yaag too.
Nao Ikeda, the sub-character designer for Final Fantasy XIII told Famitsu that "After graduating first in her class, Nabaat exercised her skills effortlessly within PSICOM and advanced steadily through the ranks. She handles daily policy and takes strategic command of the military when called for, so PSICOM's soldiers are generally always following her orders."
Yaag Rosch who is her right-hand man in PSICOM puts the protection of Cocoon ahead of everything and sees Lightning and her party as a thread to his homeland. "Rosch graduated one position behind Nabaat after a long, painful time at the academy. "He is extremely talented, though not as much as Nabaat, and he's taken a similar elite-officer path through the PSICOM ranks. He often fights on the front lines himself, leading his forces at the forefront, and the scar down his forehead reflects the harsh training and fighting he's undertaken."
