The probe that was performing a routine scouting mission at the deepest part of the sea came across a mysterious object.

It is an energy-generating [Mysterious Cube].

The researchers soon discovered that the Mysterious Cube can terminate the functions of an ancient technology that was recently uncovered.

Then without warning, Gigantic Mechanical Insects attacked from the Sea. The Navy was dispatched to stop them but to no avail. The commanding officer realized that in order to stop the massive invasion, they must use the power of the Cube at the source of their attackers.
It may as well be a death sentence since the base of their enemy is believed to be in uncharted waters.

With no other option, the Battleship Purify carrying the Cube set sail for enemy territory. If the gravity of the mission wasn't bad enough, the Battleship was sailing alone, without support or backup.

Then the situation took turn for the worse, when the Battleship was attacked by the Gigantic Mechanical Insects.

In this desperate time, [The Mysteritous Cube] suddenly shined and asked for aid.
