Touko: Nothing's wrong. 
  
  Azaka: Really? But what is with this weird feeling? Uhm, Touko-san?
  
  Touko: What is it? 
  
  Azaka: Is the Bounded Field around our office warped in some way?
  
  Touko: You've gotten sharp. 
  
  Azaka: It's not easily defined, but the air seems strange. Does that have to
  do with the distortion? . . . What's with the box?
  
  Touko: Oh no. You've seen it. It makes sense, as you're my disciple. 
  I guess I could say it's a long story . . . 
  
  (The box rustles, bangs, and moves.)
  
  Azaka: Touko-san, it's moving! 
  
  Touko: Damn it! 
  
  (The box explodes. Upbeat music plays.)
  
  Azaka: Touko-san, what on earth is this?
  
  Touko: It looks like I bought something troublesome again. 
  
  Azaka: What the heck is that box?
  
  Touko: It was something dug up that I found. It bent the Bounded Field because
  it has an alternate space inside. I was interested in the capacity of the space
  waves  inside, so to speak, and  . . .
  
  Azaka: So this was because of one of your impulses? It's not a long story at all!
  
  Touko: Don't put it like that.
