Sirius (シリウス)
A ring themed on Sirius, the god of "Fate" from "ZODIAC:CHRONICLE." Gears are worked into the design in a semi-three-dimensional form, with a clock-face motif as an accent. The straight, linear lines with minimal curves evoke the mysterious and composed Sirius.



Asteria (アステリア)
A ring themed on Asteria, the god of "Destruction" from "ZODIAC:CHRONICLE." Floral patterns taken from the costume and the blade of the naginata are worked into the design, with Asteria's blindfold motif as an accent. The curved lines evoke Asteria in battle.
