The anime adds an original scene at the beginning with Heivia telling Quenser about the Information Alliance idol Elite that is deployed in Oceania, showing him footage of one of her concerts.
In the novel, Milinda is wearing her normal Elite suit during her flute tuning scene, not the skimpy tuning suit she wears in the anime (as Milinda's tuning in the novel is based on hypnosis and self-suggestion, not technology), so the part with Quenser praising it and commenting it's his first time seeing one is also original.
In the novel, the 37th and the 3rd's foot soldiers have to walk to their mission, as the higher ups only gave them a few trucks which are being used to carry the 3rd's powered suit unit. This forces the two Objects to match the infantry's slow speed, causing the Elites to grow restless.
The scene with Milinda throwing Quenser and Heivia's jeep into the air and Oh Ho Ho saving them with some kind of mechanical arm is anime original. In the novel, Quenser's talk with Oh Ho Ho ends with him asking for a ride on the Gatling 033, as he's tired from walking. Oh Ho Ho allows him to climb on top of the air cushion engine. This is what sets off Milinda's jealousy, who starts shaking her Object and throwing sand around. Heivia asks him to hitch a ride on the Baby Magnum instead, but Quenser refuses, arguing that the electrostatic and laser propulsion method would be dangerous for him, further angering Milinda and causing her to disturb the sand even more. Oh Ho Ho then mocks Milinda by saying Elites have to be attentive and kind to their troops.
