Japanese fashion label AKROS (アクロス), known for its ACG-inspired apparel and bags, previously scored a hit with its merchandise collaboration for the anime series Frieren: Beyond Journey's End.
Now, the brand is teaming up with Ruri Rocks, the TV anime that premiered in July 2025, to recreate the waist bag used by graduate student Nagi Arato in the series. Designed to balance everyday functionality with screen-accurate details, the bag is priced at ¥10,780 and is now available to preorder through the AKROS official website.
Serialized in the manga magazine Harta, Keiichiro Shibuya's Ruri Rocks follows Ruri Tanigawa, a high school student obsessed with sparkling gemstones and jewelry. After her mother casually mentions that Ruri's grandfather used to find crystals while gathering wild plants in the mountains, Ruri sets off on a treasure hunt. Along the way, she meets Nagi Arato, a female graduate student specializing in mineralogy, and the pair begin exploring the world of mineral collecting together.
Nagi is one of the series' more distinctive personalities. She combines an encyclopedic knowledge of mineralogy with striking looks and typically wears a white long-sleeve shirt and jeans, giving her plenty of freedom to move during outdoor fieldwork.
This is the same style of bag Nagi carries while heading out to collect minerals with Ruri and the others. Everything from the color scheme and twin buckles on the front flap to the leather patch featuring Nagi's profile faithfully recreates its anime appearance.
The woven side strap used to attach a bell has also been reproduced, letting fans customize the bag with bells or keychains from their own collections, just like Nagi.
The bag measures approximately 24 cm wide, 18 cm tall, and 9.5 cm deep. Its main body is made from sturdy twill fabric with a subtle sheen, while the lining features an original mineral-inspired pattern that brings even more of the series' world into the design.
A zippered pocket beneath the front flap provides quick storage for a phone and other daily essentials. The dimensional pockets on both sides offer easy access to gloves and compact tools, while the roomy main compartment can hold an A5 notebook or a 600 ml plastic bottle placed horizontally.
