Chapter Summary: As a new threat attacks San Fransokyo, Sora is forced to confront some familiar foes, and some new fears, as the search for the next Key continues.
As a stark contrast to the chaos that had beset the city and its residents earlier in the day, night seemed to have fallen peacefully over San Fransokyo. In light of their hard-won triumph over the Heartless, it was a sort of calm that the members of Big Hero 6, as well as Sora, Donald, and Goofy, certainly welcomed. With no rampaging monsters to distract them, the collective group was making their way back to the garage to plan out their next move when it came to finding the Key. A goal that the young heroes of Big Hero 6 were more than happy to assist the trio in accomplishing considering the invaluable help they’d offered them thus far. 
“So once you guys get all 13 of those Keys,” Hiro began, ever curious. “What exactly are you planning on doing with them?”
“That’s a… good question…” Sora exchanged a quizzical look with Donald and Goofy. Though all the pair had for him were a set of shared shrugs, an obvious sign that they were just as clueless about their endgame as he was. Not that they could really divulge that information if they did have it, especially when the matter of the world order came into account. “We don’t really know. But what we do know is that we need to get them all before Organization XIII can.”
“Organization XIII?” Go Go glanced back at the trio. “What’s that, some kind of gang?”
“A gang of villainous scoundrels, bent on complete and utter world domination!” Fred zealously spun around to walk backward. “Am I right, or am I right?”
“You’re… not too far off, actually,” Sora admitted. “Whenever somebody from the Organization shows up, they bring nothing but trouble with them.”
