Dimensional Fissure, the Insectoid Nest

The Pacific Ocean was the largest ocean on Earth, with an area almost equal to the sum of the other three oceans. It was 14 times more massive than the smallest Arctic Ocean.

Countless direbeasts had been bred in the Pacific Ocean over the past 30 years, from the weakest Class 1 and Class 2 to the most powerful Stellar-Class direbeasts.

The oceans had become a forbidden zone for humankind because of the large number of direbeasts in them.

The aircraft carriers that sailed with impunity, ships, offshore scientific research stations, and oil fields were all abandoned.

Human beings had lost control of the oceans and could only hide inside the base cities and live a cowardly life for the past 30 years.

The oceans had also become a paradise for direbeasts. At first, this situation was expected to continue until humans were strong enough to kill the direbeasts and regain control of the oceans.
