"Mr. Fisher! What is this..."
The next second, under the astonished gazes of everyone, Fisher raised his fist and violently smashed it onto the window in front of him, shattering the glass.
What happened next was shocking: outside there wasn't a school at all, but rather a pitch-black space, akin to an abyss of nothingness. In absolute silence, the glass shards that Fisher had knocked out fell along the edge of the building, yet there was never a sound of them hitting the ground, as if they vanished into thin air.
And within that darkness, Fisher saw ring after ring of Magic Emblems flickering with a mixture of deep purple and white Magic Power. He recognized them as Medieval Magic Emblems composed of the Magic Power of Artificial Witches.
Thirteen Ring Magic, "Space Cage."
The quintessential work of Super Ring Space Magic, the Space Cage, the only Magic from the Middle Ages that reached beyond the Thirteen Ring.
