The Earth Self Defense Force is finally about to collect a salary, but instead of money, they are supplied with pre-paid cards to buy books. As they're discussing their dissatisfaction, a gigantic spaceship draws close, and the alarm goes off. Mishima goes to investigate but doesn't come back. As Luchini peers inside, he is confronted by a scary-looking alien. Ushiyama says he'll quickly handle things, and also heads to face the alien. He finds Mishima and Luchini unconscious on the floor. Ushiyama releases his smell waves, but they have no effect on the alien. This alien is of the Zuga race, the strongest in the universe. While Earth is in a crisis, Ushiyama is also in a pickle. Ushiyama explains to the Zuga alien the situation at his school. He gains his permission to leave, and returns to school for the time being. He sends in Saneyoshi and Shinko in his stead. Just as the Zuga aliens start to attack, Mishima and Luchini, who were lying on the ground after the beam attack earlier, stand up. They ascertain that being struck by the beam improved their abilities. Mishima correctly answers several difficult exam questions. Luchini's singing has improved. Saneyoshi and Shinko also get beamed, but learn that it only works once and the effect only lasts for three days. However, the Zuga alien has one beam left. Shinko falls to the floor struck by it. Saneyoshi, Luchini, and Mishima release their smell waves together, but the alien counterattacks. Ushiyama returns and joins the battle, but to no avail. Just when the situation looks hopeless, Kaori fires a poop beam gun, thus eradicating the Zuga alien. Shinko remains sprawled on the floor. Everyone is saddened, but Shinko comes back to life. She had sustained no injury, all that happened was that she gained five kilograms. And thus, thanks to the efforts of the Earth Defense Forces, peace on Earth was protected.
