"Was the world you came from really that wonderful? Or rather, if I wanted to go to your world, was there any solution? Any way to make it happen?"
"Just like how you came to our world—if I wanted to go to yours, do you have any way to make that happen?"
"If you want to go to my world, there's no way at all. Not even the slightest possibility. Even I have to pay a price to do it, and it only applies to me. It's completely impossible for anyone else. I'm not lying to you about this. I'm telling you a fact, the truth. Whether you're willing to believe it or not, whether you want to believe it or not, this is the fact. This is the truth. Whether you're willing to come with me or not, it remains the same. There are no other reasons, no other causes or consequences. That's simply how it is. No matter what, that's all I can say. I can't say anything more."
"Because saying too much wouldn't be good for me either. You should understand that clearly. You should know without me having to say anything more. There's no need for me to waste words here."
"With your abilities, you should understand these matters clearly. You should be able to sense them and understand what I mean. Yet you insist on asking me. What does that prove? It proves you kid has bad intentions. It proves you want me to break the rules. It proves you want me to be directly bound by those rules and dragged back to my world. If that happened, it would prove that you truly had bad intentions. Then your plan could be considered a success—a complete success. I have to say, your idea is correct.
