“There are — how do you say — things in this world our philosophy cannot account for.”

“What I saw wasn't a ghost. It was simply--myself. I can never forget how terrified I was that night, and whenever I remember it, this thought always springs to mind: that the most frightening thing in the world is our own self. What do you think?”

“If people lived forever—if they never got any older—if they could just go on living in this world, never dying, always healthy—do you think they’d bother to think hard about things, the way were doing now? I mean, we think about its everything, more or less—philosophy, psychology, logic. Religion. Literature. I kinda think, if there were no such thing as death, the complicated thoughts and ideas like that would never come into the world.”

“In this world, there are things you can only do alone, and things you can only do with somebody else. It's important to combine the two in just the right amount.”

“No matter how deep and fatal the loss, no matter how important the thing that’s stolen from us - that’s snatched right out of our hands - even if we are left completely changed, with only the outer layer of skin from before, we continue to play out our lives this way, in silence.I dream. Sometimes I think that’s the only right thing to do. To dream, to live in the world of dreams - just as Sumire said. But it doesn’t last forever. Wakefulness always comes to take me back.”

“The most frightening thing in the world is our own self.”

“How much do you love me?' Midori asked.'Enough to melt all the tigers in the world to butter,' I said.”
