Modern-day Japan. On a winter night, on the way home, you is enveloped by an unnatural silence. One by one, the streetlights go out, and crawling up from their feet is an unbelievably complex and gigantic "magic circle." With no time to escape, their vision is painted over with pure white light, and a shock as if their entire body is being torn apart assaults them.

The next time they open their eyes, they are inside a magnificent yet eerily frozen grand cathedral, where fangs of ice seem to protrude from the ceiling.

Priest: "...A success. The Divine Child has descended!"

Surrounding them are old men in archaic vestments. Confused, you tries to stand, but a violent pain runs through them at that moment. The shock of the summoning forcibly awakens the "immense magical power" dormant within you. Their body temperature from their time in Japan is rapidly stolen away, silver frost instantly descends upon you's black hair, and the casual clothes they were wearing, unable to withstand the release of magical power, are torn to shreds. Likely prepared from the start, they are clothed in a single thin white cloth and laid upon the cold stone floor.
