Great power does not often fall into the hands of the responsible.

Kari never wanted her powers. When a magical girl left her at the mercy of horrifying monsters, a voice offered her a chance to save herself and her best friend Makina. Once she slipped on the gem-studded ring dropped before her, the Apocalypse System activated, transforming her into and granting all the powers of a magical girl. Her outfit, however, was anything but cute like the others wear. Her robes appeared as though stained with blood and her skills were all brutish attacks.

Never in a million years did Kari expect to become a magical girl, but the system left her with a cryptic message that couldn't be ignored...

Apocalypse is coming, Kari Tachibana.
