A black-eyed alien baby fell from the sky.
Guest was living a peaceful life.
One day, while out for a walk...
An infant fell from the sky.
The baby's name is Meteor. He claims to be an elite scout from the edge of the universe, currently on a mission to conquer Earth. Meteor wants to live with Guest to observe the lives of Earthlings.
...Or so he says. In reality, Meteor is just a baby alien who snuck onto a spaceship and accidentally fell out. He has no way to return to his home planet and no means of surviving on Earth. In other words, he has no choice but to rely on Guest.
