Nightbook: Netherworld Debt

I inherited an ancestral business and became a "night watchman". My job after childhood is to open the ancestral "Night Book", record the complaints of the deceased souls, and settle the unpaid "debts" of the past. They say that I am the judge who walks on the boundary between yin and yang. But when I started to trace the truth behind my parents' mysterious deaths, I discovered that my name had already been written in blood-red handwriting on the latest page of "The Night Book"... Tonight, midnight has arrived. Do you owe a "debt"?
