Sorry, it just peeves me when people talk about the Unlimited Ring when they really mean the Ultimate Ring, even though it's really inconsequential. Also, you can't just purchase the Ultimate Ring, I've never gotten one from those boxes, but it might come from the Kaleido-Spinner boxes (They promise Pinnacle/Ultimate equips, after all). Mostly I've only seen them in Cash Shop Updates in Gachapon Boxes.
