Re: [Lepus]
I only remember three. The human world, the digital world, and the dark ocean. I think we only knew about those three, but Koushirou thought there might be more around. He was worried one of the enemies we were fighting was breaking the barriers that kept them apart.
The Digital World looks a lot like this. Kind of -- there's also deserts and oceans and mountains that kind of stuff. I don't remember much about the human world, besides the city I lived in there.
