第1話: ルリは手頃なクォーツを探し、ナギの助けで地質学を学ぶ
2025年7月6日 放送
A student named Ruri wants a quartz point necklace she cannot afford. She decides to travel to the mountains to find her own crystals. Instead she finds Nagi, a graduate geologist with a Mini Cooper and a medieval European war hammer for sampling recalcitrant formations. With Nagi's help, Ruri obtains a nice quartz cluster; a baggie of pigeon-blood garnets; basic knowledge of pegmatites, plate tectonics, and erosion and transport; and a yen for the earth sciences. Now Ruri wants a rock hammer. (Source: Wikipedia)
