Wait, was it already established that when they sleep and go back to Japan their bodies basically teleport from isekai world?
I thought they sleep in isekai world with body still on the bed, wake up in Japan and vice versa. Except for when they die.
Guess it means this work the same in Japan so when they sleep they teleport back to isekai world with body disappearing from the mc house in japan.
If that is the case man, I hope the glasses dude leaves before they teleport back in the room or there will be a lot of question for them....all kinds of trouble.
