An all-out war between good and evil has surfaced on Earth. An ancient and mystical clan called the Jungleman has protected the Earth for many years, embodying the five Jungle Symbols: Hawk, Rhino, Shark, Tiger, and Flamingo. They witnessed few of the Jungleman using their power for the wrong causes and banished them for their corruption. The former Jungleman returned years later with thirst for vengeance, only to see them completely changed. They call themselves the Tailed-Beast Tribe Jaken and unleashed a great attack on the Jungleman.
The war lasted days if not hours, leaving lives being taken away. Feeling all hope was about to be lost, the remaining Jungleman used the spirits of the Jungle Symbols thwarted the Jaken. But the damage had been done, and the dying Jungleman turned into small cartridge-like trinkets, where one surviving Jungleman gathered the five cartridges and disappeared from sight.
Fast forward into the modern era, the Earth has evolved and almost everything is completely hi-tech. The legend about the war between the Jungleman and the Jaken has been told by many people, and the rest thought it was nothing but a complete story... a fantasy. But everything changed when the Jaken makes a return after years of absence, vowing that all humanity will fall into their knees. Sensing the Jaken's return, the last Jungleman resurfaces and noticed the five cartridges glowing.
