The knight ‘Ail Shell’ lost his memory. He awoke in a dungeon where everything was decided by dice.

There he met the witch, ‘Grin’. Ail gained the aid of ‘Grin’, who freely manipulates fate.

To rescue someone trapped in the dungeon and escape himself,

and to recover his lost memories, Ail heads deeper into the dungeon.

Roll, manipulate, roll, manipulate!

In this dice-driven adventure, you must actively use Grin's magic!

Use fate magic to reroll the dice or even change the numbers themselves.

The outcome will reshape your future adventure!

Turn-based combat where dice manipulation overturns the tide of victory!

Using skills always requires the right fate.

That's why both allies and enemies must use dice to activate abilities.

With 'Grin's magic, you can freely manipulate these dice.

Create the fate needed to unleash even the hardest-to-use skills!

Of course, enemy dice are no exception!

What awaits you at the end of your adventure...

Your past, revealed as you reclaim your memories.

The unknown plans of ‘Grin’.

Within this dungeon, tangled beyond even magic's reach,

Where exactly will your destiny flow?
