>Might as well keep reading until it makes sense, or pages run out. Maybe we'll learn how to time travel ourselves!
You continue reading. Byakuren goes to explain how she imagines you're probably confused at this point, explaining that she is currently using something connected to a 'Word'. This word being 'Understand'. It's given her, as the name suggests, the capability to understand a few things. As such, as she is writing this, she is capable of understanding the myouren shrine will be attacked and destroyed in a month or two.
You flips the page. She informs you she doesn't understand how the fight will end, or much else about why it was attacked. Past that, the only thing she understands is you will find this book, and someone will find what shes using to receive this understanding.
She does however, feel she has reason to believe that you're a good-hearted and nice young girl, who'll no doubt use what she has come to understand for the right cause.
And then you killed her. Yeah. Great going there, Chen. You must've pretty much shattered her heart then. Actually, you kind of did.
You're a -terrible- kitty.
You have become DEPRESSED CHEN. You now add mope to every action you do.
