Perfectly Clear Mirror

The Focus Shot of Sanae Kochiya, who has almost reached the end (a Touhou LW original). She attacks by shining the Masumi no Kagami, or Perfectly Clear Mirror―one of Moriya Shrine's sacred treasures. Ancient mirrors were shaped like shallow dishes and were filled with water. Peering down into the water to see your reflection had a kind of religious significance. It was also thought that mirrors were gateways to other worlds―an idea that has endured to this day.
