Tập 6: Ruri và bạn bè tìm ra mỏ sapphire sau khi sửa lỗi ghi chú gần một ngôi đền.

6

Ruri has identified the watershed with the sapphire deposit. She, Nagi, and Yoko travel to the area and visit a shrine. Searching on foot nearby seems hopeless, partly because fallen leaves cover the ground. Ruri finds a mistake in her notes. More sand searches correct the error and further pinpoint the deposit. Climbing to a ridgeline, they find plentiful sapphires. Nagi explains how they might have come to be there. An old inscription hints at a missed clue in the shrine's name. Shown but not mentioned: Ruri's shoes and clothes are now more suitable for outdoor work. (Source: Wikipedia)
