Collect slightly odd monsters known as Permy, build a party of four, and take on strategic battles to clear stages.

Skills that exploit enemy weaknesses, elemental accumulation and reactions, and well-timed parries with limited uses decide victory or defeat.

Swap your party to adapt to ever-changing situations on each stage. Which Permy do you keep, and who do you swap out? Stack your choices and find your own route to victory.

Each stage you clear adds new monsters to your roster, expanding the options for your next run.
