Episode 4 really got me thinking more about the connection between the real world and the game world. What does this game actually mean to reality, and why is it so important? I hope the anime starts revealing more soon. Also, who is the floating girl that Tsukasa keeps seeing in that strange place? Is she connected to the girl who is unconscious in the real world? By the end, it seems like something is changing with her, but is that a good thing or a bad thing? This episode feels like one you really should not miss.
