Bizarre Apocalyptic World: Homemade 100 Billion Ghost Money at Start

“Sir, your food delivery.”

“I… didn’t order it… Oh, thanks.”  

Two minutes later. “Sir, wrong delivery. Please return it back to me.”

“I’ve already eaten it!”

“Consuming my delivery means compensation. Pay either money or your life!”

“How much? I’ll pay.”

“Only ghost money accepted. No ghost money, repayment is your life!”

Strangeness fed on humans, but couldn’t kill them arbitrarily.  

To devour humans, they must trigger the Strange Ones’ death rule against humans.  

Summer Sky reincarnated with memories of his previous life, homemade 100 billion ghost money.  

A saying goes: Money can force Strange Ones to do one’s bidding.  

All strange beings in this world either work for him or face annihilation.

When small strange beings see him, they always shout: “Run! Here comes the pro who kills Strange Ones!”
