Note that there is still no mention of a release date for the game. It’s also uncertain whether it will release in Japan ahead of the rest of the world, or if it will be a simultaneous worldwide release.

The game’s story is as such:

There are girls called “witches.” As ordinary as they are, they can wield extraordinary powers. However, as calamity spreads across the land, witches begin to be feared and detested. Before long, the Church of Longinus commenced what would be known as “The Witch Hunt.” Witches are executed one by one. But, as madness seizes control of the world, it is suddenly overrun by Curses— Woeful desires of those called “Witches of Qlipha.” Finally, the fractured land is sent adrift high into the sky. Meanwhile, the people have yet to realize. Within these girls cursed to be witches, there emanates glimmers of hope. To save their decimated world, they set forth liberating the land from darkness. For they believe it to be the right thing to do..
