Pain.
What was pain?
Was it just the physical or emotional distress that arose in response to an event such as injury or death? Or was there more to it?
I wasn't too sure myself.
All I knew was that I'd have to experience pain in order to become stronger.
This was the fastest method I had available.
Flip, flip—
Each time I turned a page, I felt myself become stronger.
But at the same time,
"Ukh—!"
I also felt an unbearable amount of pain.
There were a total of 158 pages.
Each page brought a new wave of pain, yet with every surge of agony, I felt my strength grow. It was as if the suffering was a catalyst for my power, serving as some sort of anchor that prevented me from going insane.
It also made me think about pain.
What was it, and why did I make myself go through it?
