Let's say I bring in Sora and he makes friends with Demyx for example, and going home becomes available... if he brings Demyx home to visit the Kumo shrine, then is the world just empty? Because it would be very in character for him to introduce his new friend to his brothers and to Nishiki. So does that get handwaved? Or is the world just weirdly empty? Or is there something else I am missing?
