No One's Pov

Ivan stretched after waking up; he looked out his window as it was snowing. 'We'll have to check out Hogsmeade…' he thought. He had never gone over to look, but the third years seem very excited about visiting it. He'd only been passing through but he had a look over the place at night, when no stores were open and he was rather curious as to what the fuss was about.

Ivan waited outside the door, since there would to be no teaching today, or planning of lesson plans he'd have time to have a long chat with Charles Wolf.

"Hello Charles," he said pleasantly, as Charles walked out of his room and stared at him nervously. He grabbed tightly Charles's arm and walked off to the gates. Charles looked frantic and looked like he wanted to run away at the moment.

He finally got Ivan to loose his grip and looked painfully guilty to Ivan as they stood in an empty corridor, "Yes, about being able to destroy Dark Matter… you're right, they never did complete their research…" he said.

Ivan sighed painfully, "So now what? I can't do anything if I don't know how to destroy it," he completed dully as Hermione Granger and Ron Weasley walked pass them, wearing gloves, scarves, and thick coats. "Do you have any idea?" he started again interrogating Charles. "You know how much trouble I am just being here, I need a quick solution."

"I've been researching ways, but its hard to confirm…" he said hesitantly. "Hey come on, we'll figure out something, "he said quickly noticing how Ivan looked actually sad. But before he could confirm this, Ivan face, went back to its cold look.

"Fine, let's go to Hogsmeade," he said continuing to walk, "we can talk about it there."

Hermione Granger's Pov

"What do you think that was about any way?" questioned Ron.

"I don't know…" I muttered as I shivered as we walked pass the Dementors. "I'll figure it somehow."

"Doesn't it remind you of Snape and Quirrell in our first year?" suspected Ron suspiciously.

"A bit… but Ron, Professor Wolf and Professor Kouter seem to be friends not enemies…" I added.

"Ok then, we can ask them about it later. I think there staying at the school for Christmas. Let's go to find something for Harry. It's Christmas break tomorrow," he said grinning.

No One's Pov

"Good thing, it's Christmas Break," shuddered Charles horribly, as he hid behind a tree, his head bleeding. Holding the same magical shield.

"Yeah," sighed Ivan, holding Kurogane tightly, eyeing the barren landscape. "We've gotten most of them, but still…" he sighed heavily. He was dripping wet, and covered in blood.

"It's Christmas day today… I don't know if Dumbledore is going to send out a search party… and I'd rather he didn't. This is our problem and were the only ones who can fix it."

"Yeah, let's finish it here," said Ivan as he rushed out and attacked.

Harry Potter's Pov

"Merry Christmas!" said Dumbledore, as Hermione, Ron, and I walked into the Great Hall for lunch. Instead of the usual tables, there was just one table for everyone to sit around. There was Professor Dumbledore, Professor McGonagal, Professor Snape, Professor Sprout, and Professor Filtwick. Along with Filch the caretaker, two first year students, and a Slytherin fifth-year. "As there are so few of us, it seemed foolish to use the house tables… sit down, sit down!"

"Huh, Professor?" asked Hermione, "Where's Professor Wolf, and Professor Kouter?" she asked anxiously, as we all sat down together at the end of the table.

"Hmm? I don't know, I think there coming right now though… They've been missing since the start of the Christmas break, they must have urgent things to attend to that's all," he said smiling. "Crackers!" he said enthusiastically to Snape offering a cracker, which Snape took reluctantly and tugged. In its place was a stuffed vulture hat, which Snape pushed to Dumbledore sourly.

I turned to Ron and we both grinned, remembering Professor's Lupin's class.

"Tuck in," he said advising the table beaming.

No One's Pov

As the three joined the table and joined in the feast, Professor Trelawney glided in, wearing a green dress, wearing her giant eyeglasses.

"Sybill, this is a pleasant surprise!" said Dumbledore, standing up.

"I have been crystal-gazing, Headmaster," said Professor Trelawney dreamily, "and to my astonishment, I saw myself abandoning my solitary luncheon and coming to join you. Who am I to refuse the promptings of fate? I at once hastened from my tower, and I do beg you to forgive my lateness…"

"Certainly, certainly," said Dumbledore pleasantly. "Let me draw you a chair-" as he drew a chair in mid air, and set it between Professor Snape, and Professor McGonagall.

She didn't sit down but count the people at the table and let of a silent scream. "I dare not, Headmaster! If I joined the table, we shall be thirteen dine together, the first to rise will be the first to die!"

"We'll risk it, Sybill," said Professor McGonagall impatiently, "Do sit down, the turkey's getting stone cold." Professor Trelawney hesitated, and then sat down slowly, if afraid the table would randomly combust. "Tripe Sybill?"

Professor Trelawney ignored her, she opened her eyes and looked around the table slowly, and said, "But where is dear Professor Lupin, and Professor Wolf, and his assistant Professor Kouter?"

"I'm afraid the poor fellow is ill again. Were not sure about Professor Wolf, and Professor Kouter though, they should be coming anytime…"said Dumbledore, indicating everyone should serve themselves. "Most unfortunate that it should happen on Christmas Day."

"But surely you already knew that, Sybill?" said McGonagall, her eyebrow raised.

Professor turned to look at Professor McGonagall rather coldly, "Certainly I knew, Minerva," she said quietly. "But one does not parade the fact that one is All-Knowing, I frequently act as through I am not possessed of the Inner Eye, so as to not make others nervous."

"That explains a great deal," she replied, trying to hide her sarcasm in her voice.

"If you must know, Minerva, I have seen that poor Professor Lupin will not be with us for very long. He seems aware, himself, that his time is short. He positively fled when I offered to crystal gaze for him-"

"Imagine that," said Professor McGonagall

"I doubt that," said Dumbledore, in a cheerful sort of way, but trying to stop this conversation overall, and it did, as he continued, "that Professor Lupin is in a any immediate danger. Severus, you've made the potion for him again?"

"Yes Headmaster," said Snape.

"Good," said Dumbledore, as the doors opened.

"Sorry, were so, late…" laughed Professor Wolf wearily with Professor Kouter following closely behind.

Both of them were covered in bandages. Professor Wolf had a very prominent one around his head, and some that were sticking out from his shirt. Professor Kouter had bandages that were sticking out of his shirt, and some on his wrist and forearms, which he hastily rolled down in sleeves when he saw people looking at them. The golem that followed Ivan followed after him as he followed Charles to the table.

"Yeah, sorry about that…" he said hastily.

"No harm, done," smiled Dumbledore as the students just stared. As he conjured two chairs, putting them beside Hermione. Ivan and Charles sat down sighing, and leaned back, looking like he was about to collapse. "So how is everything?" he asked.

"It's going alright…" Charles said, hesitant to let anything going on.

"Huh yeah," said Ivan groggily, as Charles elbowed him in the ribs, making him groan in pain and rest his head on the table. He looked around and picked some stuff and put it on his plate and nom nom nomed away.

When everyone was eating, Hermione turned to look Ivan sitting beside her, "Professor," she said trying to gain his attention. He merely nodded, "I was wondering do you need to go to a hospital? You're bleeding on your arm…"

He turned to look at his arm, and some blood had begun to form, "No, I'm fine, I just forgot to bandage that area…" as he grabbed a napkin to stem the blood.

"Oh, okay then…" she muttered embarrassed.

"Damn brat," muttered Charles smirking aiming it at Ivan.

"Old geezer," he muttered back forcefully.

"So Professor," asked Ron. "Why are you here for Christmas Break?"

"Why are you here for Christmas Break?" Ivan questioned at him.

"Huh… never mind I asked that Professor," said Ron hastily, ears turning red.

"That's fine Ronald," said Charles, eyeing Ivan. "Everyone has their reasons for staying at school during the Christmas Break."

"Well, it's just sir, you're new teachers, and we don't really know much about you and your assistant," interjected Harry curious at to what his friends were aiming at.

"Well… young Potter," said Charles grinning, as Ron sniggered, "you might know anything about us. But you can already see that we're not familiar with the Wizarding world as well, since we're I… think you called them muggles?"

"Yeah, but first off, can you tell me about those injuries you have, they look very new…"

"They were from falling, down a mountain," interjected Ivan seriously. "We went to look for something, and blast our luck we fell," said Ivan sighing sarcastically.

"Geez, give the kid a break, why don't you," said Charles laughing. "But in all seriousness, yes we did fall."

"Don't you need to see Madam Pomfrey, or someone who can look at your injuries?" said Hermione worriedly.

"We'll be okay, Ivan and I have a lot of experience patching our selves up, so no harm done," said Charles smiling warmly.

"Unless you're the Nurse…" Ivan muttered under his breath darkly.

"So yeah," said Charles ignoring, Ivan's comment. "What do you want to know about?"

"What about your family and jobs when you finish teaching here?" said Snape is mouth curling. He had never gotten over that Ivan had hit Malfoy, on his first day at school, and that Charles hadn't done anything about it.

"Oh…well," started Charles hesitant, "My parents died when I was 16, and right now I just find things, to make it simplistic…"

"Of what?" questioned, Harry quietly.

His face was completely blank as he said, "Who know?" Harry looked in shock at how unfeeling Charles's eyes were for a moment, before he nudged for Ivan to do it.

Ivan groaned and swore something foul, but in a completely different language, so nobody was sure what he just said. "Uh, I don't have parents, and my job is something I don't feel at all like talking about," he stated glumly.

"Huh? Why not?" questioned Ron.

"Because would you even believe me?" said Ivan looking thoughtful.

"Yes we would," said Hermione seriously.

"Okay then, I'm an exorcist," he said smirking as the students, and the teachers, who didn't know much about why they were here stared at him.

….

They were all getting ready to leave, as Ivan's left eye activated. Hermione stared at it in horror. Ivan turned to Charles, as he nodded glumly back to him.

"Where is it?" questioned Charles, walking to the door and opening it, as the students looked fearfully.

"It's not in the school, yet…" said Ivan pausing. "Fuck!" he said swearing loudly, "It's a level 4. It's on the school grounds."

"How come we never saw it?" asked Charles ready to walk out.

"Wait a moment," said Professor McGonagall. "You said you would destroy the

akuma, but one is coming here?"

"Sadly yes," said Ivan his left red eye spinning in circles. "And I think it's

minions are coming too," he said groaning. "The only thing that you can do, is to take cover, while we try to destroy them.

"We want to help, we might not know what's going on…" said Harry determined.

Ivan sniffed, "Well the only thing you can do is to go to Charles's and my rooms,

and get our weapons, because it just came," he said as a crash was heard, and maniacal laughter was heard.

"GO! Now, get one of the teachers to show you," Ivan roared desperately, as two

first years looked frightened and the fifth year looked unsure what to do, as some teachers led them away to safer quarters. Harry, Ron, and Hermione, ran after Professor McGonagall, as Dumbledore and Snape stayed to assist.

"This sucks big time, you do know that," said Charles.

"Yes, yes it does. I'm the only one here not affected by the poisoning, so I'll try to lead it away from everyone till we can fight," said Ivan not looking at anyone in the room.

"Yeah… Snape, Dumbledore, whatever you do when facing an akuma, never let it pierce you, because if that happens it'll be the last thing that happens," said Charles addressing them both darkly.

"What happens if it does?" asked Snape, as they heard the laughter get closer and closer, as they walked out the door.

"If it does, the poison will spread through your body, leaving stars on your skin, then in a matter of seconds, the poison will break your body apart leaving you a pile of dust," said Ivan truthfully.

"You say it like you've seen it all your life."

"I have," he said grimly.

He then heard the loud laugher and sobs of akuma, as he turned around and began to run.

Harry Potter's Pov

We followed Professor McGonagall all the way to where their rooms where. I opened the door and walked in side quickly. It was dark with not much in the room. Just a bed, a table and a chair, on the bed were gauze stained with blood. But beside it was a golden gun holstered in a black holder, and a sword in its sheath, still bloodied.

These were probably his weapons, I mused. I grabbed them and ran out to meet Hermione and Ron both holding a white glowing shield, with a yellow cross on the front. Professor McGonagall followed us and we ran to try to find where Ivan and Charles were.

…..

No One's Pov

"We really can't do much," said Charles bitterly, as they all stood in the shadows,

hiding from the akuma.

"What about magic? Would that work?" questioned Dumbledore.

"Honestly, Ivan and I have never tried it, since we can't for obvious control magic, but I'm not sure how it'll work against Dark Matter…" he said.

"Dark Matter? Is that what those things are made of?" asked Snape.

"Yeah, there far enough now, since all their attention is on Ivan we'll test this theory of magic on akuma…" he said walking out the door, looking both ways in case of stray akuma and ran in the direction Ivan ran to, as Snape and Dumbledore followed.

…..

Ivan ran, he had felt several guns hit him, the poisonous akuma blood enter his stream and start its destruction. But he stopped it, and reversed its flow, making it leave his blood stream. He was lucky he hadn't been hit enough times to be injured badly enough he had to rest, so he just kept running.

He saw a flash of red coming through a corridor, and stopped. That must be Ron and the others.

"Ivan!" yelled Harry frantically, "We have your weapons," as everyone saw what was behind him they looked in horror. As every akuma aimed their weapons and fired.

….

Charles was running, and then they heard a scream. It was a scream of dread and fear. "I think that's Hermione…" muttered Charles, not liking the sound that it brought, as they all stopped on the edge of where the akuma were. "Sirs, I think now is a perfect time to try magic."

The two wizards aimed and fired.

Hermione stared at the dead face of her Professor in fright, Blood streamed from his back, at where he had pushed them through the doors and stood there, not allowing a single bullet to enter.

He had fell on to the ground from the impact, blood pouring everywhere, his eyes wide and blank. His skin had flickered with black stars, as the akuma laughed.

No one said a word, they couldn't believe what had happened, and didn't want to remember it.

There was a light and some of the akuma exploded with a bang, as the akuma dissipated, out came Charles, Snape and Dumbledore, covered in blood but regardless still alive. But as the two of them saw the dead body of Ivan Kouter, they looked solemnly on.

Charles walked over to the four standing in the doorway, and picked up his shield, "Thanks… you can go now, if this is too much for you…"

"B-But what about him…" muttered Ron not looking at the body.

"He'll be fine, after a minute… or so," Charles said carelessly.

"W-What do you mean?" said Harry glaring at Charles, at to how inconsiderate he was.

"I am fine, you can stop worrying," muttered Ivan he kept bleeding from the wounds, but instead of red blood they were black, as the stars on his body disappeared. "Thanks for getting these for me," he said standing up. He held the gun and put it on his leg, and grabbed his sword, and unsheathed it. "Yeah, its better that you leave, its for your own safety."

"But how are you alive?" snapped Hermione angrily, "You were dead there for a second and then next your alive?"

"It's hard to explain…" said Ivan carefully, cracking his back muscles, gripping his sword, as it start to glow up a dark purple. "Innocence activate," he roared as he leapt and attacked.
