I'm a Fortune Teller, It's Normal Not to Be Afraid of Ghosts

I was kicked out of my home by my master when I was thirty-one years old. I walked around the world with an apricot-yellow flag in my hands, breaking evil spells for my employers. I was used to seeing too many evil people and cunning ghosts. Even so, I still talk about ghost transformation! Because humans can't deal with ghosts! The moment a ghost misses the Master, the person is already doomed.
