And Neku, who wouldn't have a prayer of finding his way into another world by legitimate means, has been dragged here by some other power. Another Angel; it has to be. He's starting to wonder if Joshua's failure to return is due to something other than the limitations of another District.]

Sounds like the same story I recall. Good seein' ya, Phones... though I've gotta say, the situation's a little weird.
