A long time ago, the ancient saviors of humanity founded a village as their haven, with their descendants said to assist humanity in times of extreme chaos. This village, Kunlun, is located just beside the infamous "Last Dungeon"—a place where monsters of unimaginable strength reside and which serves as the hunting grounds for Kunlun residents.

However, as someone whose upbringing defies common sense, Lloyd's innate power might just prove to be the key to end the crises enveloping the kingdom!
