-Karma Akabane Model Ring-
This design ring is inspired by Karma Akabane. Drawing inspiration from his striking red hair and sharp demeanor, we combined a deep almandine garnet with cool black spinel.
The arm features sharp carvings reminiscent of a knife, expressing Karma Akabane's dangerous charm and speed.
The "Class 3-E" engraving subtly incorporates the world of the series.
This cool ring embodies Karma Akabane's blend of strength and beauty.
