Exchange students (Percy Jackson, Harry Potter, hetalia)

Prologue

Hogwarts(Year 4, couple days before summer)- No one's POV.

Ron, Harry, and Hermione walked up the staircase to Dumbledore's office. Unaware to why they were being called. Hermione opened the door to a happy Dumbledore. But then again Dumbledore was always happy...

Hermione: "You needed us Professor."

Dumbledore: "Ahh yes. Please have a seat."

They sat down without hesitation

Dumbledore:" Here at Hogwarts we are hoping to expand our attendance to North America..."

Harry:" But we already have wizards from every country attending Hogwarts."

Dumbledore: "Yes, but we only have one American, Alfred. And the rest of America has an overpopulation of wizards, especially in New York."

They were all confused but didn't question him

Dumbledore:" I will be assigning one student to all of you and you will show them around Hogwarts and answer any questions they have."

Ron noticed how Dumbledore looked more excited than normal. This isn't the first time Hogwarts has had exchange students. Two years ago, in third year, we got and exchange student from every country, Ron wondered why Dumbledore would want to expand Hogwarts even more. Geez, I sound like Hermione, Ron thought. 

Dumbledore: "Hermione, you will show around Annabeth Chase. I think you two will get along very well. She is the only girl that is transferring, she is blond, has silver eyes and peach skin."

Hermione frowned. She didn't want to waste time showing some girl around that would judge her for being too smart or a muggle-born when she could be studying.

Dumbledore: "Ron, you will be helping Nico Di Angelo. He has black hair, eyes, and has pale skin. He is the youngest and forced to endure more tragedy and danger than most people would in a lifetime. So he appears to be mean or tough at a first glance. But in truth he is a very caring and loyal boy."

Ron quietly groaned in frustration. Why do I have to get the one with a bad childhood? I bet he's going to be just like Malfoy! Ron thought to himself.

Dumbledore: "And Harry, you will help Percy Jackson. He has black hair, sea green eyes and tan skin. He is the oldest out of the three and is very famous in his school. In fact all of them are. But Percy is a very easy going but doesn't care for the lime-light. So if all of you would not ask them why they are so important in their school."

Hermione and Ron couldn't help but notice how similar Percy was compared to Harry. They probably looked the same too, black hair, green eyes, tan skin. Harry had a feeling the Percy was either going to be a good friend or

Harry: "Why are they important professor?"

Dumbledore: "You will find out in good time, Harry."

All three Gryffindors mentally sighed. They always here Dumbledore say as an answer. And sometimes it doesn't even make sense. For example; three weeks ago Ron asked Dumbledore what time it was and Dumbledore just said' You will find out in good time, Harry.'
