The 2 Party System has been improved for better combat!
When you divide your party into 2, the group you aren’t controlling turns to stone and has greatly increased defense. Some Yokai cannot be attacked from the front so use your stone companions as shields and strike your foes from behind.
Enjoy thrilling battles never before seen in Hyakki Castle!
