Because of the success of their escapades with the first Object, Qwenthur and Havia are transferred to the entrance of the Mediterranean to assist in combating another Object which has been drilling and selling oil to terrorists. After the Object attacks, they are able to infiltrate it and attach bombs to it, but they are unable to destroy it, until Milinda arrives in time for support.

Qwenthur and Havia's unit is sent to intercept forces from the Mass Driver Conglomerate in the Iguazu region of South America. Meanwhile, Milinda receives an invitation for a "mock battle" against the Legitimacy Kingdom's newest Object, the Bright Hopper, under the implicit understanding that she deliberately lose against it. After Qwenthur and Havia land in Iguazu, they find no evidence of any Object. At the command center, Froylatia is contacted by Halreed, a high ranking noble and the pilot of the Bright Hopper, who requests that Froylatia allow him to defeat the enemy Object. In response, Froylatia orders Qwenthur and Havia to find and destroy the enemy Object before the Bright Hopper's arrival. Judging from their conversation, Havia theorizes that Froylatia and Halreed have some sort of personal connection to each other.

Still surprised with Ohoho's true appearance, Qwenthur attempts to subdue her but she easily subdues him. Returning to the battle in a much better condition, Ohoho apparently gains the upper hand against Milinda, but Qwenthur uses his wits to send a coded message to Havia that instructs him to set a trap that brings the Rush's AI to a deadlock. Qwenthur then tricks Ohoho into believing that her superiors have activated the Rush's self destruct system, and allows her to eject and escape, leaving the Rush to be captured intact. However, Ohoho's superiors promise that her next Object will be far more powerful.

With the Battlefield Cleaning Service's assistance, Qwenthur manages to stage a diversionary attack on City Slicker's Objects, damaging one of them and knocking off a piece of its armor. Upon analyzing the armor, and with assistance from Granny, Qwenthur discovers that dummy Objects are built out of a low cost ceramic material. Using a drone, Qwenthur takes advantage of the dummy Objects' faulty AI to trick them into firing on their own support convoy, setting off the volatile plasma gas they are carrying and inducing thermal shock on the dummy Objects' ceramic hulls, causing them to shatter. Milinda then arrives and destroys Indigo Plasma, killing City Slicker as well. Upon returning to base, Qwenthur finds out that the BCS is not a registered company under the Capitalist Enterprise. In fact, it turns out the BCS is a front for the Intelligence Union, who assisted Qwenthur in order to destroy the strategic AI technology the Legitimiate Kingdom stole from them.
