Ahhem, "it might be a little bit of a stretch" is putting it mildly. The final resolution was out of this world, but I suppose the author chose not to drag the story for too long and have the characters going in circles. That, I can respect.
I suppose we will see glimpses of Kaeda, Tsubasa, and their friends in the next arc, too? So it's like a... uhhh... trauma party ensemble cast?
Oh boy.
