Fightdoll

Eleven people are abducted by Aliens, yes! But why‽ . . . . In the beginning these eleven people abruptly finds themselves on a rectangular planet—as there's nothing without a reason. These people are actually there to play a footballlike but distinctly played Game called Fightdoll with Aliens! And when these eleven people from eleven Earth's countries apprehend their queer fate they are extremely appalled, for Aliens are apparently creatures that they can't possibly defeat. These Game they are to play was called Fightdoll because the Aliens who came from Uranus and the Humans from Earth will have to fight on a football field for the Doll; with the aim to maneuver it to the Targetdoor, a door in the planet's sky which is the only way out of the planet. The Doll, meanwhile, is the only key to the Door, and in between the Earth team and the Uranus team, the team who is first to strike the Doll on the Target via cannon will have their way out and go back to their world, and the team who fails to strike the Doll on the Target will have to face the consequences of their failure by perishing in the exploding facility.
