Synopsis: While on a field trip, Jae Farley exploded along with eleven girls. However, what was waiting for them wasn’t heaven nor hell, but an alternative universe filled with magic and fantastical races.

How will the twelve otherworlders, whose fates are connected with each other, fare in such a chaotic world?
“If you can change into anything you want, would you?”

“How about you change me instead?”
“It would take a miracle for that to happen.”
"Then, through a miracle, it shall be."
