Publisher's Summary
The unprecedented gigantic Object, Manhattan, has activated. A bog of a war between all four world powers is beginning.

The extraordinary 20,000 meter Object, Manhattan, has suddenly begun to move. The appearance of that "strongest Object" has eradicated the lines between enemy and ally. Also, a single attack from its electromagnetically-launched reactor cannon routs the 37th Mobile Maintenance Battalion and sinks the Flagship 019 that Quenser and the others have infiltrated.

Who is it that provides a helping hand to Heivia and the others after they survive but are isolated in enemy territory: Oh Ho Ho the Information Alliance idol Elite, or Wraith-tan the devilish commander!? There is no "clean war" here. It's a rampage full of remote grenades, precision-guided grenades, flying drones, quadrupedal robots, an Oh Ho Ho powered suit, and space weapons! This is how the Information Alliance does things.

Welcome to the technology war. Near future action!
