In a distant world, a powerful demon appeared, swallowing part of the world, including towns, residents, and everything within, into a magical space known as the Demon Void. Countless heroes became demon hunters and ventured into the Demon Void to defeat the demon and reclaim their world.

None ever returned alive.

That was when a prophecy emerged: “One day, a girl will become the strongest demon hunter and destroy the powerful demon.”

The girl from the prophecy grew up under the weight of those expectations and became a brave warrior, setting out on her destined journey.

Meanwhile, in another distant town, there is a girl with no connection to the prophecy at all.

Her name is Airi. She simply admires demon hunters and dreams of becoming one herself. With a bright, innocent outlook and boundless optimism, she sets off on her own adventure, guided only by her innocent fantasies.

The first thing she does is politely and forcefully requisition the home of a cat girl as a base of operations!

This naive lady is the true protagonist of our story.

As Airi, players will explore and battle through a variety of Demon Void dungeons in this 3D action-adventure game.
