No not yet. Sorry. I was just looking up the pricing info and specs. Fyi guys it needs ios7. The last few releases were available in ios6 but if you're still in that you won't be able to play it.
I heard there is Iap for rare cards. And a gatcha system where you have to pay and a random skill or "Sophia" whatever the skills were called come out.
I've been checking every 30 minutes in Japan. Nothing. I even woke up early this morning when it hit 00:00 in Japan. Good news (possibly) is that they're waiting to time a world wide release of some sort simultaneously.
Same been checking there website too. But I see you can buy chaos rings prequel trilogy on Amazon jp now.
