The mercenaries respond quickly, and Potaria arrives just in time to spot a woman fleeing into the jungle. Potaria broods about it later in the Fantom Club. The woman's name is Monica, and they were childhood friends.

The next day, Kan Yu chooses a task force to join him in an attempt to locate the guerrillas, who are believed to be hiding in Zonmu village. The task force includes Chirico, Kiderra, Potaria, and Shako. They arrive at Zonmu some time later, and Kan Yu orders all the villagers brought forward for questioning. The villagers deny any connection with the guerrillas, but Kan Yu orders the village searched. The search turns up Monica.

A firefight ensures which carries into the nearby mountains. Once again, the Blue At appears and Chirico attempts to communicate with the pilot. Separated from the battle, Chirico gets out of his AT and approaches his opponent on foot. The Blue AT opens its cockpit, revealing that the pilot is not Fyana after all - it is another Perfect Soldier altogether, a wiry young man who knows Chirico's name!
