During the natural disaster, our building turned into a bloody colosseum.
I thought I could survive by grabbing food and water, until I discovered that the cruel neighbors were searching for a "ledger" that was more important than life.
I thought I would be safe by hiding in the pipe, until a pair of inhuman green eyes lit up in the darkness.
Now, I was injured and trapped in a ventilation duct, with bloodthirsty monsters behind me and "one of my own" in front of me who wanted my life.
And the account book that can solve all mysteries and determine life and death is tightly held in my hand...
