Market Value

  • This item can be sold for 100 Ryo at the store.


  • The item is a reference to the infamous annoying advertisement of a product Head-On, whose advertisement consisted of nothing but the words "Head-On - Apply Directly to the Forehead." repeated three times. It was sold as a homeopathic medicine, which means that, as homeopathy doesn't work, it has no effect at all. To avoid lawsuits, the marketing department decided not to include any factual claims about the product.
  • As of September 2008, there are two versions of HeadOn available in stores: "Extra Strength" and "Migraine". Chemical analysis of the Migraine formulation has shown that the product consists almost entirely of wax.
