Chapter Four: Enter the Ghost of Blackest Past

"KAGOME!!!!!!!!"

Kagome heard it through her miko powers which she had left at Hogwarts to protect the students. 'He won't be able to go inside ever again,' she thought as she fell once again into sub-consciousness, bringing back memories of someone that followed as a shadow, under the evening setting sun. 'Inu Yasha protect them, they need you there, don't worry about me, promise me that you'll do it. Promise so I can fight without worry.' The message was transported by the small connection to her powers.

Inu Yasha felt her around him and he heard her voice in the wind and the aurora now surrounding the school, it howled to him trying to make him promise and he did with a promise of his own 'I'll get you back Kagome don't you worry, I'll protect them and I'll find you, I won't let anything happen to you I promised your mother.' The shadow of a kiss implanted a happy smile in the wind as he saw her eyes in the sky, a whispered 'I love you' as it faded to the setting sun.

Inu Yasha felt his blood boil and his demon blood react to losing someone so important. He knew what he needed to do and went back to the mess hall to address the students on the situation. Everyone turned to him with a look of hope that they might still be able to have a celebration and that their beloved teacher was not in the hands of the most feared wizard of this century, Lord Voldermont.

"Keh. Listen up pups, Kagome left this place protected. Her aurora now ranges from the station to cover the whole school and village. Don't worry she'll get back to us, but I promised to stay and keep you safe, although that bitch should learn not to tie me down but she needs to know this." Everyone turned to each other and back to him as they knew he had more to say. Turning with a scowl on his face Inu Yasha said gruffly. "Kay you are to stay within the aurora, if you cannot see the aurora, then you are in deep shit. I'll mark the perimeter and where the edge of her protection ends. I'll be patrolling the area day and night. If you have no reason to be outside during anytime beside when the classes are in progress then your little behinds are mine. You cannot lie to a dog demon; I smell all emotions and know when you are lying. I know no magic, so I will ask the help from a student to teach each lesson. Any questions?"

Too many hands were raised as mostly everyone had a question to be answered by our loveable dog demon. Half of the Slytherins looked to their headmaster, Professor Snape for some form of confirmation on the matter. Then he stepped forward with an air of supremacy to rival Inu Yasha's stubborn quality.

"I think the Headmaster would agree with me that you Inu Yasha are not suited for the job as Defense Against the Dark Arts teacher and so the post would naturally go to me." Snape sneered little did he know Inu Yasha had been waiting for the chance to beat this little git to a pulp for insulting him when he had first arrived at Hogwarts. Snape's eyes went wide open as he came face to face with a pair of red eyes with a blue pupil, Inu Yasha had been pushed to the edge and was ready for action, or in this case a massacre.

"What were you saying you piece of snake youkai shit? You need an ass whopping? I'll be grad to commence the beating for you. You know I have no idea why I want to kill you but-"The Demon Inu Yasha didn't even get to finish as a voice from above or should I say Kagome's aurora went into effect. A booming voice shouted 'Osuwari' and Inu Yasha plummeted to the ground. They a bright blue/pink light surrounded itself around Inu Yasha's sword that sat by the doors and brought it to Inu Yasha's outstretched hand, turning him back into a hanyou with no memory of what just occurred.

The voice, just as sweet as Kagome explained the occurrence. "He turns into a demon when his sword is not by him and he is beyond angered. So if you see him with out his sword bring it to him. The sword was built to keep his demon blood from overriding his human blood and so that he wouldn't lose his mind. And Inu Yasha even if I'm not there doesn't mean that you can get away with a couple of catastrophes, Kay? Later I have a date with an ass whopping of a demented wizard and his crew." The voice faded and everyone turned to look at a surprised Inu Yasha sitting on top of an unconscious Snape.

"Keh. What happened? Don't tell me I. . . "Inu Yasha trailed off as many of the students nodded in agreement with Inu Yasha's thoughts. He knew that if it got dangerous there would be no way for him to save the students in his Demon form and all. Hell he didn't even remember what happened; well it must have been good to be sitting on that annoying asshole Professor Snape. Getting up and dusting himself he made his way to where the teachers were conversating in a dark conner.

"We must send them home." Professor McGonagal replied to whatever Professor Flitwick had said. "It's bad enough we have demons running around but now the Dark Lord has taken a teacher. They might be in danger if we do not do something."

"Keh the Old Hag is right. But Kagome said not to send them home. She wants them to study and they will under my watchfull eye. I wont let anything happen to the students here or Kagome will have my ears for it." Inu Yasha turned to Professor Flitwick. "You work on charms right?"

"Yes of course I am the Charms Professor, but what can I do? You know very well that I'm not capable of doing anything very fantastic like say Professor Dumbledore but I can do many things. Why do you ask anyway?" Professor Flitwick backed against the wall a little to keep from being completely terrified from the dog demon intimidating form in front of him.

"Oi I need you to teach these pups to turn their magic into scrolls. That way they might be defenseless to the eye without their wands but with scrolls in their pockets they might stand a chance." Inu Yasha turned to look at the students who were having conversations on the tables. He heard many of them worry but most thought he was their second weapon while Kagome is away. Thinking that these kids are weird he moved on to say to professor Snape. "And you don't piss me off. These pup's I'll train so that they might fight with a weapon, do you have an armory?"

Professor Dumbledore looked on with a serine face, his eyes dancing behind his half-moon glasses. "I think we might I don't know. You'll have to as Mr. Flinch when you see him. If we do, the weapons might be a little rusty and they might need to be sharpened." Dumbledore signaled Mr. Flinch from his post by the double doors. When Mr. Flinch showed up Dumbledore asked with a small smile on his old worn face. "By any chance MR. Flinch do we have an armory?"

"Why of course we do Professor Dumbledore. We've had one for years, although the weapons are heavy and rusting, and might need to be re- sharpened. Why do you ask? Plan to let me torture those little brats for dumping dung in the third hallway or for trying to fry Mrs. Norris?" Mr. Flinch nearly panicked when he saw a clawed hand flexing in his view. Turning with a slight shiver of fright he saw Inu Yasha grin with a feral glint in his golden eye. The students near them, mostly Harry, Ron, Hermione, Ginny, Neville and Luna, were looking at the two and then tried to act like they haven't have been overhearing the conversation.

"Look Mr. Flinch I have no need to let you touch the pups, for Kagome's annoying reasons. I need you to help the pups train so they might fight incase of an emergency." Turning to look at the small group of Gryffindors and Ravenclaw near them he said, "Harry may have fought your enemy, but the others might not be lucky. I got in a fight with a wizard that used a sword, wouldn't your pups do the same? Wouldn't you like them to say Mr. Flinch help them learn something usefull and you will no longer be an outsider in the school but a friend? Keh you need practice with your magic. You might not have any as I've heard, but you can do something better by teaching them combat. Think about it. We have a ha-ro-iii-n to continue. Food and story about my travels with the wench, for the pups."

Everyone in the Mess Hall turned happily that they were still gonna be entertained and began to settle down in their respective tables and look up at the ceiling that now danced with many bright candles floating and a stormy eerie look. Food appeared all over the tables. Ramen, pasta, pumpkin pie, apple tarts, bowls of candy and chocolate frogs, pumpkin juice and apple cider graced the lips and many hams, turkey, and pot roast filled their bellies. Most had finished eating when the tables moved and they were now aligning the walls, Ravenclaw next to Gryffindor and Slytherin beside Hufflepuff. The staff table had no remaining change. In the middle a platform stood and it began to glow green making it look like a forest.

"Okay pups be quiet. Its time to tell you of the time I met that wench, and I was freed from my sleep of fifty years. Kagome I need your help here." Inu Yasha turned to look as the forest scene changed from a dark green to a sunshine one and a well appeared, Kagome sat on it wearing her school girl uniform. Inu Yasha moved to the shadows to let Kagome play her part, then he was grabbed from behind by a tree, he struggled at first before he realized he had to look a sleep; faking sleep was a cinch since he's done it many times.

/Where am I? Ojii-san? Sota? Mama? The god tree I can always find my way home from there/ The image of Kagome struggled to pass many trees when she came before Inu Yasha, stepping to where he was she said /Excuse me I'm lost can you help me? Hello/ Stepping up to him she looked around before her hands twitched and she grabbed his ears squeaking them. Some of the girls aw-ed as they saw the scene. A fake arrow came from out of nowhere and nearly hit her as four more surrounded her. An old priestess came forward many began to say that was Umbridge when she was young.

/Who are ye and what are you doing in Inu Yasha's Forest?/ The prietress moved from the center of the village of many of the women began to comment on her.

/She might be a kitsune, with that out landish look./

/I think it's a demon come to destroy the village/

/Do you think we won't stay much longer from the wars plaguing the other villages./

/She looks like my dead sister Kikyo./ Many of the girls gasped as they saw, the old aged Kaede stand in front of Kagome exsaming her. The scene changed when Kagome was beign chaced into the woods. Ligh pured on to Inu Yasha's form as a transparent arrow pierced his heart 'Brings back old memories' he thought right before he remembered he was suppose to insult Kagome when he saw her. Kagome landed right infront of Inu Yasha.

/I'd expect better from you Kikyo. After all you are the guardian of the shinko no tama. Why are you running from Mistress Centepiede you could pin her with an arrow as you did to me./ Inu Yasha saw his past flash before him.

/You're alive!. . .Hey I'm not this Kikyo person you are talking about my name is Kagome. Ka-Go-Me!!! AHhhh!!!!/ Mistress centepiede slammed when Kagome had been sitting and then grabbed her from the waist with her fangs when she didn't move fast. To all the students horror Kagome was flung from a hight of thrity feet and fell to the ground floor as a little ball of glass fell from her body.

/The Shinkon no Tama is mine!!!/ Mistress centepiede slammed to the floor trying to get the Shinkon no tama from where it had been now in Kagome's hands.

/Girl hand it over here. Give it to me!!/

/What is this? The hanyou Inu Yasha stuck to a tree? Watch as I devoure the Shinkon no tama and become the strongest demon to ever walk this earth./ Mistress Centepiede tied Kagome with her tail, to Inu Yasha's form on the tree as she took the jewel to her mouth.

/Girl can you get me free?/ Inu Yasha watched as the jewel he always wanted to posses was swallowed by Mistress Centepiede.

/How? And Should I do it? You want the jewel too./ Kagome looked into his golden eyes.

/Do you want to die stuck here with me?/ Inu Yasha turned to Kagome looking into her eyes.

/No Kagome don't do it. He'll kill you too./

Kagome grabbed the transparent arrow with her transparent hand and said as she yanked /Be free Inu Yasha!!!/ The arrow disapered with a blue glow and Inu Yasha sprang into action slicing Mistress Centepiede into bits and pieces.

/Keh wasn't even worth my time. Now where is the jewel/

/Kagome can you see where the jewel glows?/ Kaede helped Kagome take out he Jewel from the stomach piece of Mistress Centepiede.

/All that trouble for this little piece of glass?/ Kagome looked at the bright pink glow emiting from the jewel.

/Yeah well hand it over unless you want my claws to caress your flesh./ Inu Yasha stood there flexing his claws to emphasise his point of killing her. The light in the Mess Hall came on again and the scene faded with Inu Yasha still flexing his claws.

"Well that's how we met. Next time how the hell she put this stupid rosary beads on me. Now to be pups ne need to delay. You have lessons tomorrow. Keh stupid wench." Inu Yasha looked at the retreating forms of the now tired but still excited kids. They had watched as he relieved his first day of meting Kagome, yet he wondered if he could have changed his attitude how will his present be.

"That was great Inu Yasha hope tomorrow is better." Ron walked away being hauled by a very angry Hermione arguing about studying and things like that. The Slytherins were the last to walk away and Draco Malfoy was commenting on Half-Breeds in a wisper.

"I would think you have learned your lesson from what Kagome told me." Inu Yasha saw Malfoy go pale as he turned to look at him with a frightened look. "You have class with me tomorrow and I'll make sure you'll enjoy it, if you continue with that attitude. Remember I'm your only defense against what want to kill you outside of the school, do you think you should be insulting me?"

"No sir. I'm sorry, I'm not gonna do it again I promise. "Draco stepped back followed by Goyle and Crabbe. They ran out of sight before Dumbledore walked out of the Mess Hall.

"That was a very exciting piece of work. I'm surprised Kagome's aurora managed to make herself seem very realistic. I hope to see the same entheutiasm from you Inu Yasha after all I think the students will appreciate a change of routine and would like to know how you and Kagome spent your time traveling in the past." Dumbledore walked past him to the right side of the hall, where the Dormitories of the staff laid.

Thinking of Kagome and how lonely it was gonna be in bed with out her.(A/N: Not in those ideas you perverts, he means that there will be no more Kagome in her bed while he slept in his tree in her room.) With a determined look he walked to the third floor where their room was situated in the office of the classroom. Walking in he nearly gasped as he saw her laying there sleeping. Walking over to her he tried to grasp a strand of hair but his claws passed through air. 'She's not really here. But she's trying to make me feel that she is here.' "Good night, Kagome." With that he went to his tree as he heard her say. "Good night Inu Yasha."

Kagome woke to feeling like shit that got ran over by a lawnmower, her body ached and she had blood caked on her head where she had hit herself. A Black shadow moved and she got ready to use her powers before she noticed it was a black dog that was in the same dark dungeon of god knows where they were both in.

"Come here sweetie. What's your name?" She asked as she coddled the giant black dog that was now rubbing it's head to her breasts and trying to lick her ear.

A voice in the shadows, but it came from him said in an eerie tone" Sirius Black" The dog moved to where there was some form of light that still penetrated the dungeon from a small crack.

"Sirius Black? Wait aren't you. . .? weren't you. . .? How did you. ..?" Kagome didn't finish when the door opened to reveal the root of all evil in the Wizarding world, Lord Voldermont. There was a silence a shifting of pad feet before a light was produced by the wand of Voldermont.

"Whom were you talking to miko?" Voldermont sneered in anger. His red eyes the only thing visible trough the black cloak he wore. Three Death Eaters were behind him holding chains and rope, Kagome guessed to chain her and keep her from escaping.

All her miko training and the magic books didn't go to waist as she threw a misty looking ball of miko energy into the middle of the dungeon. She was not ready for the dog to grab her hand and run with her nearly on his back. They flew through the large group of wizards and muggles, and half breeds. They surprised to say the least as they saw her zoom by on the great Black Dog that was Sirius. Kagome clung to him like a life rope as they jumped from the second floor out the window. They she saw the Dragons. They were caged by a magic bared barrier.

"Turn to the Dragons I have an idea!" Kagome said as she rode the Dog (A/n: I'm not gonna put rode Sirius because that's just wrong.) He turned with a shake of his head as if saying 'You are one crazy miko.' As he neared the Dragons they saw many wizards with a shake of her hand she threw some of her power at them putting them to sleep. The Dragons narrowed their black beady eyes as they turned to look at the approaching miko and dog. They narrowly missed a blast of flame.

"Stop!" Kagome through her miko powers at the barriers and it shattered as he miko powers caressed the dragons calming them. "We need your help to get away from here. Will you help us in exchange for your freedom?" The dragons got images of them flying and carrying them to a building then leaving to a woodsy place where a human wizard made sure they were well fed and no one could ride them or use them as they pleased. With a nod, one of the three dragons bowed it's head and let them climb as the Death Eaters and Lord Voldermont came out of the house. "Go!!!" She screamed as the dragon took flight with wizards trying to shoot them with their wands, to no avail for Kagome's powers still protected the three dragons; one of the dragons carried a small nest of four eggs.

They flew to where the wind sent them to where many students and people had gone to sleep, to where wizards studied and held some hope of a better tomorrow. Kagome turned to a nodding Sirius. "Hey Sirius why are you still a dog? Can't you change into your human form?" The small shake of the shaggy head told her he couldn't but the eerie voice of his said "I'm not strong enough and it's a spell that holds me so."

"What if I could maybe break the spell what would you do?" Kagome petted poor Sirius on the top of his head. Turning to where a loom of a tower showed from a cloud. "We need to go down." Kagome felt the dragon understand and then was led to the cloud right when she saw, the other dragon's eggs begin to shake. "Hurry the eggs are hatching." With a quick image of a baby dragon falling from the nest, the dragons plummeted face down first to the field bellow them. The first to land was the female whom carried the four eggs just as one cracked and opened to revel a red Horntailed dragon with yellow eyes and silver claws. The other two dragons landed and began to look at the hatching baby dragons as the mother stood and looked proud of her self. With a tinge of miko powers Kagome turned to an on coming Dog Demon as he made his way to where the dragons were, sword out.

"INU YASHA!!!"

Inu Yasha paused in mid run as he spotted the miko he missed. Seeing her with a Black Giant dog at her side and Dragons made him wonder if this was the real Kagome he remembered from a week ago before she disspeared. Then as she ran to him dirty yet with a sunshine smile on her face he knew she was here to stay and had fought her way through hell with the Dragons and the Black Dog.

Kagome flung herself into his arms as she neared him, laughting with joy as he hugged back with equal force. "I missed you Inu Yasha!" She happily exclaimed as he spun her around with his own happiness. "Oh this is Sirius Black and well the dragons got us here, but they seem to be having little ones come and look." With that Kagome pulled Inu Yasha by the unoccupied hand towards were the dragons were leaning on the ground watching the second baby dragon hatch.

Inu Yasha wondered in awe as the second baby dragon fought his way through the egg shell that held it captive. As it poked a little claw from the crack and cried out, he looked to Kagome where she stood looking at the process with fascination. 'I wonder if I'll ever have a pup and is she'll be the mother of them.' His thoughts were interrupted as Professor McGonagall came running at them wand raised and night gown flowing behind her. Right behind her were Hagrid, Professor Snape and a very nasty looking Draco Malfoy.

"Told you there were Dragons Professor." Draco exclaimed as they neared the group. One of the dragons spotted them and saw the wands then turned ready to use it's deadly tail horns if needed.

"Stop." Kagome sent some of her energy to the dragon caliming it, reassuring them she will take care of it, to go back and watch the little ones come into their world. Turning with a sigh as the dragons obeyed her command, she made her way where the Professor and the students were standing ready with their wands. "There is no need to fight. The dragons are just protecting their young which have had the fortune of being born here and not in the clutches of Voldermont." Tuning to look where Inu Yasha was still gazing at the baby Dragon that was coming towards him, she said. "You see they are harmless, I just need to ask Weasley to send a letter to his brother Charles in Romania to see if he can accept some dragons that need a home."

"if you would open your eyes Professor Higurashi, you would see these monsters would kill our students if they stay." Professor Snape commented as McGonagall and Malfoy somewhat nodded.

Hagrid on the other hand was excited as a can be and asked quietly. "It sure would be nice if. . Um I could see a hatching of some baby dragons. Can I Professor Higurashi?" Kagome turned to the dragons relaying the message with her powers and images of the story she heard of Hagrid hatching his own baby dragon and crying when it had to go, with a nod from the female she nodded saying he could. "Thank you Professor." With that Hagrid ran to catch up were Inu Yasha stood with a baby dragon rubbing on his panted leg.

"You see they are harmless. Voldermont had them caged and used them because they threatened to kill their younglings. Wouldn't you do the same if one of your young was in danger and the only way to keep them safe was to follow orders?" Kagome turned to McGonagall and then to a terrified Draco and last to stoned- Face Snape, with a nod of his head he turned and left with Draco at his heels. "Thank you."

"Now if we need to send word to Charles Weasley then we need to wake up his brother Ron Weasley." McGonagall said as she looked to where the Baby Dragon was trying to knaw on Inu Yasha's scabbard.

"no need to Professor McGonagall." Ron said as the little Gryffindor Group took of the invisibility cloak that belonged to Harry. Ron and Hermione tuned to look at the Dragons as Harry turned to Kagome with a smile on his face.

"Welcome back Professor Higurashi, long time no see." He said as Kagome began t laugh then made a parchment and paper appear in her hand and handed it to Ron. Ron took the paper and began to scribble something or another while turning to look at the dragons every other minute.

That's when Harry saw the great Black Dog. He narrowed his eyes as he recognized the shaggy form from anywhere. Kagome blocked his view and whispered in his ear, "He's stuck, so I'll keep him hidden don't worry. I'll find a way to turn him back human. He saved my life and I owe him that much." With a nod of his head he turned to walk to Inu Yasha whom was holding the baby Dragon the tail and was getting a good berating by it in its baby language.

"Lets just leave them here I'll keep them guarded by my miko powers. Come on you guys are past your bedtime." Kagome said shooing the Gryffindors to their dormitories. As she past Professor McGonagall she heard her say "They are somewhat beautiful when not attacking."

As Kagome crawled into her Bed and Inu Yasha to his tree she said, "Why is there tree leaves on my bed?" Turning to a blushing Inu Yasha she smiled knowing what had occurred. With a slight happy grin she laid down and went to sleep, never knowing one of her pillows had gone missing while she's been gone.
