(Satisfying moments without being a wish-fulfillment story + Fast-paced + From weak to strong + Slow-burn)
This is an utterly chaotic world. I took on a sinister high-interest loan to save my sister! I earn coins by doing good deeds, then borrow supernatural abilities to exorcise ghosts. The price is having my body corroded by ghost energy until I turn into a ghost! Fail a mandatory repayment task, and my closest family will be erased! To stay alive, I’m doomed to sink ever deeper into debt on a road haunted by vengeful ghosts!
