Kingdom Hearts lore is extensive, convoluted, and confusing. I don't mean that as a dig – I am a Metal Gear fan, after all – but even after playing every game in the series, I've still got to read a half-dozen wiki pages and watch a few lore videos before I start remembering the specifics of any given plot beat. That's why I'm so impressed that Tetsuya Nomura and the rest of the devs have managed to remember a small, but key detail about Heartless behavior in Kingdom Hearts 4.
The first Disney world announced for Kingdom Hearts 4 is Pixar's Coco, In the recent D23 trailer, we see a pair of Heartless emerge and start creeping toward the film's protagonist, Miguel, who is the only living person in the vicinity – they completely ignore the other denizens of the Land of the Dead.
