Prologue - The Seed that Upheaves the WorldA voice sounds from afar.
"Onii-chan."
It"s the voice of my little sister Saki.
"Hey hey Onii-chan you hear me?"
But I"m feeling sleepy so I ignore it. I can"t open my eyes. I wonder why I"m so sleepy.
"Onii-chan hey!"
What is it Saki? I"m sleepy. Don"t wake me up.
"You can"t do that Onii-chan. You"re sleeping too much."
It"s fine right? I"m sleepy. I"ll be skipping school today. Ah, but, you have to make sure you go, you know?
"What are you talking about? C"mon, open your eyes. Get a grip on yourself."
I don"t want to.
"You can"t do that ~! C"mon c"mon, I"ll give you a hand, so get up!"
Impossible.
"Jeez ~, you"re really such a handful, Onii-chan. Open your eyes and face me. Before it"s too late."
...... too late? What are you talking about?
"Onii-chan hey, you have been out cold for a month now you know?
--- Inside the labyrinth of a girl called Gunjou-san.
--- Ever since you have been stabbed in the chest with a sword by some woman called Kiri-san."
What.
"But if you continue sleeping like this, you will get killed......
So hurry up,
Even for just a second,
Even for just an instant,
Onii-chan, wake up!"
On hearing those words ---
I awake from my blissful dream.
