Uvarovite Trapezohedron (ウヴァロバイト・トラペゾへドロン Uvarobaito Torapezohedoron) is a magical device created by Sophia Measley on Johanna's order. Johanna called it an "observer". The device consists of 13 percent Uvarovite, 37 percent meteorite iron from the South Pole, and the rest was Emerald Tablet. Johanna put this device into Francine, Ursula of the Bookshelf's artificial body before sending her to Ayamegaoka to investigate parallel worlds.
