Oh, he’s an unsuitable alien. As with Earthlings, there are also mismatched aliens, so they have to flee from their kind. That’s what happens to Oh, who ends up on Earth fleeing from his fellows.
Oh, it’s a disaster, so he accidentally ends up making known to his enemies that he’s on Earth. Luckily for him, he will meet a girl named Tip, who will help him in his flight.
Tip is also a somewhat special girl, immersed in a very personal search, and that is why both of them understand each other so well. Through Tip and the adventures that both suffer in their flight, Oh will understand what it is to be a human, something that is not easy when you come from a planet so far away.
The two will learn a lot from each other, and at last they will know what a real home is.
