Ruri Rocks key visual – Ruri finds minerals in the river, Youko examines them under a microscope
Steven Reynolds 
Upcoming slice-of-life anime Ruri Rocks (aka Introduction to Mineralogy) has a new key visual out as the series gets ever nearer to its release. (No premiere date yet, but we do know it’s in 2025 so…).
One half of the latest Ruri Rocks key visual shows jewelry-obsessed Ruri out on the river bank with Shouko, who has just shown her how to spot a mineral in the water.
Ruri, of course, is crazily excited as finding minerals that can be made into jewelry is her greatest dream come true.
The other half of the new visual shows Nagi in the school library, showing Youko how to notice even the tiniest of minerals under a microscope.
The latest Ruri Rocks key visual was released on the anime’s official X account with the comment:
“I should be able to find some too.”
Sometimes they dip into the river, and other times they peer at unknown minerals through a microscope – guided by Nagi, Ruri dives into the world of mineral collecting.
Ruri Rocks anime adaptation details

The plot of Ruri Rocks is described in Volume 1 of the manga like this:
“Mineral Collecting is the Modern Treasure Hunt!”
High school girl Ruri Tanigawa, who loves gems and jewelry, dives into the world of mineral collecting—venturing into mountains, rivers, and caves.
Numerous minerals make an appearance, including quartz, garnet, pyrite, gold dust, and fluorite. Plus, the collection scenes, featuring specialized tools like panning dishes, hammers, and topographic maps, are packed with excitement.
A fully-fledged science adventure, grounded in the author’s expert knowledge of mineralogy!
