It's Naota and Haruko Vs. Kamon and Canti in a battle with airsoft guns. As this deadly fight wages on, Kamon challenges Naota to a duel! The winner is left undetermined, as some of Naota's friends interrupt the duel and talk to him about how he saved the city from the satellite the other day. This causes the power to get to his head and he begins to act manly. This disgusts Mamimi and the others. To make matters worse, another Medical Mechanica comes out to threaten the city. Will Naota handle the situation as calmly as did the last time? Or, will his over-inflated ego get in the way?
