Discover this Demon Slayer Open Ring - Black Metal with Blue Wave, designed for everyday wear. This ring includes an adjustable open metal band with enamel finish, a pattern that wraps around the entire ring, a black band, and a blue wave and red flame placed on either side of the opening; it comes in one size and is a single model with no options to choose.
The band is black all the way around, and both ends feature an enameled shape facing each other: a swirling blue wave on one side and a red flame on the other. It is the only model in the series without a character.
Water and Flame come from the Sun
The major Breathing Styles did not appear separately. Sun Breathing, created by Yoriichi, is at their origin, and branches such as Water or Flame derive from it. In Demon Slayer, this lineage connects fighters who are otherwise very different, such as Giyu for Water or Rengoku for Flame. The visual effects change, and so do the temperaments, but the styles remain tied to a common source that runs through the history of the Demon Slayers.
This open ring places a blue wave on one side and a red flame on the other on a black band. No character is depicted, and it is the two breathing styles themselves that tell the story. Both motifs refer to two major breathing styles of the universe, which are not independent: both Water and Flame belong to a lineage that goes back to Sun Breathing. The piece of jewelry thus brings face to face two different branches of the same story.
"Both the Water Breathing and the Flame Breathing derive from the Sun Breathing."
An open ring, adjustable by hand
It is the most understated of the twelve models, and the only one with a black background all the way around. The two enameled shapes are placed face to face on either side of the opening, which means the ring can be read differently depending on the direction you turn it.
The ring is open at the back and can be adjusted by hand: you can tighten or widen the two ends slightly so that it fits the chosen finger, making it a one-size-fits-all piece. The pattern goes around the entire ring rather than being limited to the top, so the ring can be read from any angle and has no set orientation for wearing. A metal border surrounds each area of color and separates the shades from one another. This ring is suitable from age 14. The blue wave and the red flame face each other on your finger.

This makes it possible to browse the shop by type of product, but also by character and by the visual style each fan prefers.
Collections devoted to the best-known characters
The world of Demon Slayer rests largely on its characters, each with their own story, their own style and a visual identity fans recognise instantly.

A shop built for different kinds of fan
There is no single way to be a Demon Slayer fan.
Some are after a figure to complete a collection, others want to wear something inspired by their favourite character, display a Demon Slayer katana, decorate a room, or simply find a gift idea.
That is why we deliberately keep the catalogue varied, so it answers collectors, anime and manga fans, and people looking for a Demon Slayer gift for someone close.
Every category and every collection is designed to make that browsing as clear as possible.
A clear experience, centred on fans
We want discovering the shop to stay simple.
Products are organised by category, by character and by visual world, so visitors can move easily from a product to a related collection, then to a blog article or to other products that might suit them.
