The fight between humans and a new race known as the Aloken was wreaking havoc on Trieste, a primordial country created by the makers of darkness and light. By completing a ceremony to summon strange beings and overwhelm the Aloken, humans won the battle. However, Karon who was guarding the portals to the otherworld, invaded the land with unearthly beasts as a result of this ceremony. The remaining monsters slain the people, destroying humankind.

The seal deteriorated with time, and the terror of Karon's return reignited. The 'Incar Order,' which represents the current global order, created new abilities and weaponry to combat the Karon and named it Dekaron, which means to oppose Karon.
