-Kaede Kayano Model Ring-
A ring designed with Kaede Kayano in mind.
The distinctive twin tails are incorporated into the design as a motif, and the arm of the ring is engraved to resemble a knife. The Class 3-E engraving subtly expresses the essence of the work.

This ring captures Kaede's essence, exuding a dignified aura amidst its brightness.
