In Xenoblade 2, I believe there was a monster called “The Infernal Guldo.” As the worlds approach each other, a Guldo that is in the Land of Morytha from ‘2’ is being projected to the opposite world; that’s the kind of phenomenon [occurring]. The Fog King, the black fog monsters, that’s what that’s all about. To put it simply, the two world have attached together partially, and the effect of that is a phenomenon in which you see the materialization of particles as a black fog. And when that is heightened, annihilation occurs. Quite a few of my staff might not know about this, either (laughs). And by the way, the woman on the ID card that the Guldo drops is from an ordinary woman. It’s not Galea
