Earlier via a tweet from the famous industry insider Wario 64, we got to know that a demo for Ys IX: Monstrum Nox has been made available for western players now.
Here's the official description of the demo, from the PS Store:
"Take a glimpse into the mysterious city of Balduq with this Ys IX: Monstrum Nox demo. Choose between one of two key locations to explore, and experiment with the brand-new Gifts and Monstrums before your full adventure begins."
Ys IX: Monstrum Nox is set to release on February 5 for Europe (February 2 in North America) this year.
