On his way back home from school, Kurase Hirotatsu made a little side trip out of boredom. In a deserted alley he found a telephone pole with a QR code. A QR code that invited him to a game called 「Dungeon Seekers」. Being fed up with his dull life, he downloaded and started the game since he didn’t have much to lose anyway. Little did he know that this would change his life forever, pulling him into a totally new reality where he’d have to fight for his and Earth’s survival.
