Meteor-san Strike desu!

At the age of six, Kobayashi Hiro told a lie that continues to haunt him: he claimed to have been abducted by aliens. Although the hoax was quickly exposed, the resulting national attention transformed his hometown into a pilgrimage site for UFO enthusiasts. Years later, when the strikingly beautiful Yamada Meteor transfers to Hiro’s school and declares herself an alien who needs his help to save Earth from destruction, Hiro assumes it is merely an elaborate prank targeting him due to his past. He soon discovers that Meteor is deadly serious. She has arrived to determine whether humanity deserves salvation from the monstrous asteroids hurtling toward the planet. To prove mankind’s worth to the universe, Hiro must complete the missions she assigns, no matter how eccentric or risqué they may be.
