Story

There are girls who many call "witches."
Although they themselves are ordinary, they can wield slightly extraordinary powers.
However, such powers would turn those girls into targets of the Witch Hunt.

When the "Curses" soon emerge, one girl bravely rises to her feet.
The people detest her, but she presses on, fighting for the fate of the world.

For she believes that is the right thing to do...


  • Encounter a girl whose only wish is to live, and the Witch Hunt that steals it all away.
  • Behold stunning boss battles where forging the right team is the key to victory.
  • Fight auto-battles where you accumulate rewards just by letting time elapse.
  • Discover more and more about each girl as their stories unravel.
