The Holy Grail of the Fantasy City

A city of over a million people is suddenly trapped beneath a barrier. Inside this barrier, which shrinks step by step and allows no one to enter or leave, a brutal war is underway.

Everyone inside the barrier is doing everything they can to survive until the end. Only those who make it to the end can touch the Holy Grail, which can make any wish come true!

That's right, it's a combination of a battle royale and the Holy Grail War!

In the lower-level Holy Grail War, the fight is basically a battle royale game. The intermediate-level Holy Grail War adds high-tech weaponry.

As for the advanced Holy Grail War... When mages and special forces soldiers fight to the death, when magical artifacts clash with guns and cannons, when heroic spirits trade blows with Iron Man, who will claim the supreme Holy Grail, and what wish will they make?
