Gegege no Kitarou S01E25 - Kubire-Oni's Curse

Without thinking too much of it, Mana downloads a curse app and inputs the name of a classmate. The person she cursed suffers a slight injury and a creepy notification from the app appears on Mana's phone saying that if she doesn't input another name within three hours, the curse will return. The curse app spreads quickly among people, and soon Mana receives notification that she's been cursed. As the curses on the people in the city increase, hair begins to grow from the cracks in Mana's cell phone case... Will Mana be able to break the chain of curses?!
