Description

Adds a single English quote from Brave Story by Miyuki Miyabe.

And now that I'm finally here, I understand. My journey through Vision wasn't to reach the Tower of Destiny at all. The journey itself was the point. It taught me that even if I relied on your power to change my destiny, it would only be this one time. I'm sure that I'll know many more happy times, and many more sad times. I can't avoid that. That's life. And I can't go asking to have my destiny changed every time something sad happens to me.
