Meteo-san Sutoraiku desu

Kobayashi Hiro’s childhood lie about being abducted by aliens turns his town into a tourist destination for UFO enthusiasts. Years later, when Yamada Meteor transfers to his school and says she is an alien, Hiro assumes she is playing a prank. Meteor insists that Hiro is the only one who can help save Earth from monstrous asteroids. She has come to test whether humanity deserves to be saved, and Hiro must complete a series of missions to prove its worth to the universe. The missions, however, are a little perverted.
