I Raise My Long Sword to Slay the Evil God and Protect the Human World to Ensure Peace.

Behind the bizarre world, there is a forgotten truth hidden. The shadow of ancient myths is spreading quietly in the gaps of modern civilization. Monsters that were once considered fictional are sneaking into human society in an unknown way. Amid the hustle and bustle of the world, a group of otherworldly people emerged. They either hid in the streets or walked in the dark night, guarding the world in silence with their mortal bodies. Under the bright appearance of human society, undercurrents are surging, and strange things emerge one after another. And in those corners forgotten by the world, the ancient gods have not really left. They are either sleeping or in another form, continuing to guard the secrets and balance of this land. "I hold a long sword and swear to kill the evil god under my feet. I use my flesh and blood to build an immortal wall on earth. I swear to protect this peaceful world and peace for all eternity!"
