The Devil's in the Details

"Good morning class!" the black haired man called jovially from the front of the classroom. He was grinning, leaning against his desk and had his long black hair tied into a low ponytail. Once everyone was closer to him, the ones in the first few rows could see that his eyes were red. Harry cringed slightly and the man's eyes locked on him.

"You would be Harry Potter, yes?" the man asked and Harry nodded, though he kind of didn't want to. The teacher smiled at him, "I look forward to the present you'll be sending me in the future."

"What?" Harry blinked, confused. The man just gave him a secretive smile before addressing the rest of the students.

"I know most of you haven't seen me before," he started, leaning back on his hands and scanning the group of seventh years. "I wasn't at the feast to be introduced, unfortunately. While I will be teaching here, I still have my old job and I was... busy, when I should have been in the school. This will happen again, but don't worry!" he grinned, his teeth slightly pointier than normal, "I already have arrangements for a substitute during those times. You'll meet him then.

"I'm all sure you want to know my name, so I suppose I'll tell you. My name is Lucifer. It's a pleasure," the word was purred and most of the students shivered, "to meet you."

The muggle born and raised all paled. Hermione raised her hand slowly and he waved a hand in her direction. She swallowed before speaking, her voice somehow steady. "You wouldn't happen to be..." she broke off. "I mean, that name has... connotations."

Now his grin was positively gleeful, "As, yes, it is known, isn't it? Quite right, it's true. Ten points to Gryffindor."

"You mean..." another muggleborn whispered, eyes wide.

"Oh yes," Lucifer agreed, looking very satisfied with himself. Draco growled slightly.

"What are you talking about?" he barked, glaring around the room. Most purebloods were in similar straits and they were all frowning.

"You pure ones wouldn't know, would you?" their teacher mused. "Pity. It takes the fun out of it, but oh well. I'll have to explain.

"Lucifer is the name I much prefer and is the one I had before I fell. Now, most like to call me Satan or the Devil. I am the King of Hell." He smiled pleasantly at all the students, who were all pale. "My sub is a very good friend of mine, but please don't be alarmed when you meet him. He knows not to harm you."

"And who would this be?" a Slytherin in the back asked. Lucifer shook his head.

"Ah, ah, ah. You'll have to wait until he arrives. It would ruin the surprise if I told you now."

Harry had a very bad feeling about that.

Then again, if fake-Moody had been a good teacher, maybe the King of Hell would be too. Hopefully neither him or his substitute would try to kill Harry.

A/N: Here have another story collection because one of my friends coerced me into it. Not really, but still. Because apparently I'm funny.
