On the eighteenth-year-old awakening day, the whole school laughed at me, and I awakened with a blank IOU.
The school bully slapped me over and I handed over the IOU.
Either sign or rebound hurt.
He did not believe in evil, so he punched three times and was admitted to the ICU.
From then on, everyone was afraid of this piece of paper.
S-class strongmen lined up to ask me to sign, and the space fleet had to give me an IOU even when it came.
I collected debts from the whole universe until I turned to the back of the IOU——
The previous holder carved a line of words three trillion years ago.
I haven't dared to read that line of writing until now.
