In the Cyber Heaven, a former judge of the Book of Life and Death who was demoted as a "data recycler" discovered that all humans who were deleted by the system as "worthless" were actually used as nourishment by higher-dimensional beings - and every memory he recovered was a weapon of resistance.
In a world where everything is quantified, those "worthless" moments - a purposeless waiting, an unrequited smile, a useless memory - are the last epitaphs of mankind.
"If the system determines that your life is worthless, I will fold your tears into paper cranes and let them fly in the data ruins for a thousand years."
