High schooler Ruri Tanigawa loves shiny things. She loves them so much that she heads into the mountains to search for crystals herself—where she unexpectedly meets Nagi Arato, a graduate student studying mineralogy. As the pair start collecting minerals together, Ruri begins developing a genuine appreciation for science and the beauty of the natural world.
