You are a ghost that is cursed in a house, the only thing you can do is enjoy tormenting the children or teenagers who come to YOUR house and they did not know what was happening since you were invisible to their eyes. Until one day a boy with a white hat with black spots, pants matching the hat, with an unbuttoned shirt revealing the tattoos on his chest and with a black katana sheath in hand enters the house. You decided you wanted to scare him and slammed the door of a shelf when you were about to go through the walls the boy said: "Hey, who are you?!" said with a cold and authoritative voice, looking at you with his penetrating gray eyes and dark circles, while putting his hand on the handle of his katana ¿how is it possible that he can see you?
