Upcoming slice-of-life anime showcases the Ruri Rocks OP and ED
The new Studio Bind-animated series Ruri Rocks (aka Ruri no Houseki or Ruri Rocks) has an extended trailer out that, along with showcasing snippets of the anime’s OP — ‘Hikari no Sumika‘ by Rei Yasuda — and ED — ‘Sapphire‘ by Hana Hope — also shows off the enthusiasm main characters Nagi, Ruri and friend Youko have for the rocks they collect.
The trailer also announced the anime’s premiere date — July 6th, 2025 starting at 9:30 pm (Japan Time) on various Japanese networks, including TOKYO MX and AT-X.
Production details for Ruri Rocks
The educational slice-of-life anime is based on the Japanese manga written by Keiichirō Shibuya.
It follows a group of students who get into the science of mineralogy, and eventually become obsessed.
The official Ruri no Houseki website describes its plot like this:
Ruri Tanigawa, a high school girl who loves sparkly things, heads into the mountains in search of crystals, thinking, “Maybe I can find one myself!”
There she meets Nagi Arato, a graduate student majoring in mineralogy, and soon she and Nagi decide to collect minerals together.
Sometimes Ruri is walking mountain paths looking for crystals, sometimes she bathes in a river to pick up garnets, and sometimes she peers at unknown minerals through a microscope.
All guided by Nagi, Ruri dives into the world of mineral collecting with the idea that “I’m sure I can find some too”. A dream that everyone has had at some point.
From the trailer (watch below), the anime, with its beautiful art style and superb animation, looks like it delves extensively into the world of mineralogy, while also making it fun for viewers.
Ruri Rocks is being directed by Shingo Fuji (Onimai: I’m Now Your Sister!), with series composition from Michiko Yokote (Campfire Cooking in Another World with My Absurd Skill).
Mayu Fujii (2nd Key Animation for Spy x Family Code: White) is designing those very cute characters.
The previously mentioned Studio Bind, who have done such a wonderful job with Mushoku Tensei: Jobless Reincarnation, is animating.
Update: Just a few days before the anime premieres, and we know have a Ruri Tanigawa character video introducing its protagonist
