Hiei Jaganshi was sitting in a tree, above his sister Yukina. He had his teeth clenched, and was trying too growl, as not to give away his position. Yukina and her boyfriend, Kwabara were on another one of their 'dates'. He watched with a grimace as they walked through the park hand-in-hand, as that oaf, Kwabara, reached down, and plucked a flower from out of the ground, and slipped it into Yukina's hair.

'This is making me sick.' The little fire apparition was about to leave, when a giant snowy white owl swooped down, dropped a piece of yellowing parchment, which Yukina caught, and flew off. Looked puzzled, she opened it, but held it back at arms length, as though she could not read, or understand it.

Suddenly, a large brown owl swooped over him as well, dropped a piece a yellowing parchment, same as Yukina's. He had to jump down a few branches to catch it, as not to give away his location though. When he caught it, he glanced down; he saw that Yukina as still reading her own parchment, eyes open wide. She must have sent Kwabara home though, because he was no longer there.

He climbed a few more branches to insure that he was not spotted, and then he looked at the envelope. It was addressed,

Mr. Hiei Jaganshi

In the tree at the park, Tokyo, Japan.

Hiei raised an eyebrow in suspension, then, cautiously, slid open the back of the letter. Two more pieces of parchment fell out as well. He caught them quickly, and held them up and began to read.

Dear Mr. Hiei Jaganshi,

We are pleased to inform you, that you have been accepted at Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment.

Term begins on September 1. We await your owl by no later than July 31.

Yours sincerely,

Minerva McGonagall,

Deputy Headmistress.

Hiei stared at the letter. This was a sick joke pulled by that damned Yuusuke, it had to be. …But then…how would Yuusuke know that he was in the tree? And why would he send Yukina a letter as well? And why did he choose to send it by an OWL?

Hiei pulled out the second piece of parchment, thinking it would tell him what the hell was going on.

Dear Mr. Hiei Jaganshi,

Given your nature, we would prefer it not to tell anyone where you came from, as they will all either panick, or just downright think you are insane. Three other demons will be accompanying you to the school, however. Miss Yukina Koorime, Mr. Yoko Kurama, and Miss Nina Jaganshi. Please do not inform anyone that you are leaving as well, although I have already informed Lord Koenma of your absence. When you arrive, you will be special 'transfer students from Japan, and students of our new Defense Against the Dark Arts teacher, Prosser Genkai. You will automatically be in sixth year, and be sorted into your different houses.

Have a nice summer.

Yours Truly,

Albus Dumbledore.
