  Big Sis: This town is just the product of an empty calculation, nothing more. Everything outside it is all Papier-mache. So, I have to ask, why do you insist on rejecting change?
  The Gardener: Who knows... I can only say that it's in my nature.
  Big Sis: I believe... You're a damper. You're here to negate a certain amount of change and stabilise the town. However, you can't handle anything beyond that amount. I'm altering the very foundation of this world. No mere Gardener can stop me.

Chapter 44

• Yomikawa reveals the complete truth behind the world they are in, boomeranging back to the same reveal that the Gardener made about West Yomogi and anything within it being a simulated reality.
  Yomikawa: The computer is approximately 1.2 meters long and fusiform. They say it's still floating somewhere in outer space. And supposedly it is the city we live in. It's pretty amusing when you think about it. All of us are crammed inside this object that looks like a large lemon.
