The Legitimate Kingdom stages an operation at Victoria Island including Baby Magnum and two other Objects, Snow Quake and Active Sledge, to ambush Indigo Plasma and stop the man behind it, Prizewell City Slicker. As Indigo Plasma also uses infantry as part of its tactics, just like Qwenthur and Havia had assisted Baby Magnum on past occasions, several detachments were sent to assist on the mission. After helping to deal with an enemy platoon, Qwenthur and Havia discover that the soldiers are dispersing some sort of gas that triggers a massive explosion once ignited by the enemy Object's Plasma Cannons, putting both Baby Magnum and Snow Quake in a disadvantage. To make matters worse, the Legitimate Kingdom forces are informed that the Active Sledge is ambushed and sunk by six other Objects which appeared by surprise, and quickly regroup with Indigo Plasma, whose pilot, who is no other than City Slicker himself, demands them to surrender.
