Glenn had been through more battles than he could count.
Countless people had died or been wounded at his hands, from the human race, beastkin, demons, spirits... even the gods.
At last, he grew tired of living this way.
"This is so boring. Why not take a trip to the future?"

With Glenn's arrival, people gradually realized that a terrifying being recorded in ancient texts seemed to have returned to this world.
