Synopsis
During lunch break, Yuzo Ogata's train car lit up with a summoning formation — and he noticed one beneath his own feet too. Light flashed. He opened his eyes alone in the empty car. Everyone had been summoned. The princess who cast the spell looked at him and said, quietly, "There should only have been four heroes." He was the accidental fifth, left behind in an empty train car, wondering what happens to him now.
