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