A/N: Thanks for all the continuous support! =) I seem to be getting more and more attention for this fic, and I'm glad you're all enjoying it so much.

Warnings: Yes, this is a crossover. However, you do not need to know anything at all about Harry Potter. All that needs to be explained will be. If you do know about Harry Potter, you'll just have a sight advantage.

The companion fiction to this is If Only You Knew, told from the Harry Potter characters' point of views. But, as I said, there is no need to read that story or know anything about Harry Potter in order to understand what's happening in this fiction. I do encourage that you do read it, though, if you want the full experience of the universe I've created.

Disclaimer: I don't own Yuugiou (Yu-Gi-Oh) or Harry Potter.

Chapter 5: Akiraka ni Suru (Reveal)

Things seemed to get even louder once the Missus ceremony had ended. Yuugi looked around, confused. Didn't these people have any respect for the dead? Many of the female students were weeping uncontrollably. Yuugi couldn't help but feel as if these displays were… fake. The tears were too huge, the cries too loud. It seemed like Yuugi's suspicion from before was correct: most of these people were here because of the fallen's celebrity status.

"I know you didn't know him, but do you wanna see the memorial up close?" Ryou asked from next to him. Yuugi glanced over to see a tiny frown on his friend's face. It seemed that Ryou shared the same sentiments as him.

He turned his eyes back to the huge sea of black crowding in front of the memorial. "Eh, I'm good. Maybe we could next time? I just… It wouldn't be right of me when all these other people want to see it," was Yuugi's reply. He kept his mouth shut about his other thoughts. He didn't want to offend anyone who might have been listening.

Ryou nodded. He packed away his violin again and held the case close. "I don't think there's anything else we need to do, especially because Magistra needs the rest of the day to rest. Is there anything you want to do?"

"There's a lot I need to learn… Library?" Yuugi asked. It had been a long time since Yuugi willingly read some books, but Yuugi couldn't play ignorant forever. Maybe I could learn more about these dreams I've been having, too.

"Go, Yuugi. Grow strong. Then, perhaps, we'll be able to meet face-to-face."

Yuugi steeled himself as he and Ryou began to walk back toward the castle. I have to see him again. Nothing was going to stop him. Nothing.

The crowds began to thin out the closer they came to the school. The two boys passed by two of the students huddled together. "What do you think happened?" a boy whispered.

"The Dark Lord got to him, that's what!" a girl answered.

"But he was Harry Potter! He faced him before and won!"

The girl rolled her eyes. "He survived. Face the facts—he was just a few years older than us. How was he supposed to defeat one of the darkest wizards of all time?"

Yuugi frowned when the two went out of earshot. Thankfully no one else got in their way walking up to the library. Unfortunately, when they arrived the huge doors were shut. Ryou commented that the librarian, Madam Pince, was probably out of the castle with the others. The albino sighed and shrugged, motioning Yuugi to follow him. They walked across the floor until they were in front of their rooms.

Yuugi hadn't seen the door from the outside before. It looked identical to the Soul of Purity and light minus the man and wings. The blonde woman smiled just as gently at the two boys from her portrait. "Ah, so he's awake," she commented, brushing some dust off of her simple white dress. "A pleasure to meet you, Mister Motou. My name is Felicity."

There was a talking portrait which seemed to have a consciousness of its own guarding the entrance to their living quarters. Awesome. Yuugi couldn't help but gape for a few moments. At her laugh, a fierce blush overcame his face. "U-Um, nice to meet you too, miss?"

Felicity giggled again. "You two look exhausted. Password?"

Yuugi was once again left guessing until Ryou took pity on him. "Sanare," Ryou stated. The portrait swung outward, allowing the two teens to walk in. "It's Latin for 'to heal,'" the albino explained. "You need to remember it; if Magistra and I aren't around, that's how you'll get in by yourself. Felicity won't accept anything else unless she senses that whoever needs to enter is in mortal peril."

They entered the main room, where there was a large bookcase occupying one wall. Ryou ran his finger across the spines until he found one in the H section. It was a rather large tome, causing the teen to stagger back once he pulled it out. Yuugi ran over to help Ryou carry it to a nearby table. The title Hogwarts: A History stood stark on the old book's cover. Ryou explained that this would explain most of what Yuugi needed to know about the school. He jokingly said that this would be enough to keep Yuugi occupied until dinner.

"What're you gonna do?" Yuugi asked, pulling up a chair.

"I'll check our potion stores," Ryou replied. He pointed over his shoulder at a closed room. "Probably brew some of the simpler remedies. I wouldn't blame you if you fell asleep reading that. Magistra made a few annotations and stuff in there to help you get to the more important things. Good luck!"

And so Yuugi read.

His heart leapt at the slight chill surrounding him. Yuugi wasn't quite as nervous about the Shadow Realm as he opened his eyes. The flutter in his chest wasn't from fear, oh no. He couldn't hold back his gasp at the footsteps behind him.

"Aibou. Why must your heart continuously pine for me?" came the all-too-familiar baritone. "An… obsession like this is dangerous. I would rather you not hurt yourself."

I don't care, Yuugi thought. He didn't dare let this out verbally. He'd probably get scolded more. I just need to see you again. If I could see you, this would all be worth it.

The footsteps walked around him. "But knowing your stubborn streak, little one, I doubt that you will cease so easily." The shadows shifted to reveal a humanoid shape. The only defining features were the sudden crimson eyes which appeared. Tears immediately sprung to Yuugi's eyes. The figure reached out a hand but paused. It fell back to his side. "You have questions?"

Yuugi bit his lip, willing his tears to go away. "Y-You walked through the doors to the afterlife, but you're still here with…" He trailed, searching for the words his other half used the last time they met. "Unfinished business. Are you d-dead or alive?"

The figure began to pace back and forth. It was a long while before it spoke again. "You can say that I am in an in between, a limbo of sorts. I am still able to influence the Light—your—Realm, just not as powerfully as becoming a spirit."

A pale hand reached to the empty space above Yuugi's heart. "If I'm able to piece the Puzzle back together again, will you be able to come back?"

The crimson eyes closed.

"Please! You need to come back! I—"

"We will see in time, little one. Just… take care of yourself first. Do I make myself clear? I refuse to see you deteriorate even more on my behalf." The shadow's voice hardened significantly. "But…"

Yuugi took a step back. "But?"

A chuckle. "It is a refreshing change, aibou, to see you being selfish. It is better to take care of yourself before others. You need to. I only wish that you wouldn't hurt yourself in the process." The eyes opened, shimmering with that same emotion from before that Yuugi couldn't quite place. "Please take care, aibou."

The next day saw Yuugi waking up at sunrise. He woke up in his room, assuming that either Ryou or Kiseki brought him back. Looking to his side table, he saw the massive Hogwarts: A History neatly bookmarked where he left off. Yuugi sneaked out of his room to see another next to his. A tuft of white hair peeking out from beneath the covers told him that Ryou was still asleep. As for the bedroom at the end of the hallway, it was empty.

Continuing to explore, Yuugi reached the end of the hall and turned right. A large floor-to-ceiling window was obscured by a tiny shadow. A lithe figure sat with its back to one of the sides, long flowing robes nearly touching the floor. "Magistra?"

The shadow shifted. "Good morning, meus discipulus. Come, sit with me." The woman's shadow grew when she stretched out an arm. Her long sleeve told Yuugi she was wearing yet another style of dress.

Yuugi scampered to the windowsill where he took some effort to haul himself up onto it. It was hard to see the woman's features in the morning sun, though she continued to look outside. Her long sleeves draped over her form, the peach just a few shades darker than her natural skin tone. It looked normal enough, but Yuugi was sure the gown was made of some sort of magical material. It bent the light in such a way that it shimmered with every minute movement.

For the first time since his arrival at Hogwarts, Yuugi truly didn't feel pressured to do anything. He breathed deep.

"You know, you can ask me anything," Kiseki began, still not looking at him.

"Why am I here?" Yuugi asked. He hugged his knees close to his body.

Yet she still didn't turn to face him. "Why do you think that you're here?"

Yuugi curled a fist to his chest. The emptiness intensified. "I feel… There's this hole where my heart is supposed to be. Yesterday I felt like my heart was gonna burst with everything that was going on. And I have these dreams…" He shook his head. "I'm so confused."

"Yes, even if I were not an Empath, your confusion is quite tangible." Kiseki turned to him then, allowing Yuugi to see the small smile on her face. However, this smile wasn't normal. It had a tint of sadness amongst the myriad of emotions he couldn't read. "You are here to learn, Yuugi-kun. That way you can harness this newfound power that you didn't know you had. Tell me: do you believe that fate led you here? That you have another destiny to fulfill?"

Destiny. Fate. They were words that Yuugi knew all too well from his journey with the Millennium Items. But how much did he really believe in it? He had often heard his other self talking about destiny and fate; Atem definitely trusted in it. But Yuugi? He guessed he accepted the ideas. However, at the same time, he and his friends had defied what destiny had supposedly laid out in front of them. They had continuously changed what the Millennium Tauk predicted, but Yuugi supposed that it had a magic of its own. The same could be said of the Millennium Eye.

If fate truly led him here, Yuugi wasn't complaining. Nevertheless he wouldn't let fate take away what he cared about again… not without a proper fight. The Ceremonial Duel proved that Yuugi was strong enough to live by himself, yes, but that didn't mean that Yuugi wanted to. Not anymore. Not when he was given so many opportunities. Not when this facsimile or whatever it was of Atem was placed within his reach.

"I'm here to help you and Ryou. What you choose to do after you've learned to harness your powers is ultimately up to you," the sorceress explained, bringing Yuugi back into the present.

"How can we thank you enough?" Yuugi asked with a frown. "You've already done so much."

"Seeing you smile is enough," Kiseki replied. She looked back out the window. "Your Inner Magic continues to grow. Without guidance… without guidance, your powers could spiral out of control. Our branch of magic is sorely underestimated." She paused, and Yuugi didn't miss the fists the woman made on her lap. "My Inner Magic manifested at your age; it is when wizards and witches reach their majority. Unlike you two, I had no one to turn to."

Silence encompassed them until Yuugi worked up the courage to break it. "Again, thanks." He tried to smile. It didn't quite work out, but his mentor seemed to understand his intention.

She laughed softly as not to wake Ryou. "Serious subjects aside, is there anything else you wanted to ask?"

Ryou walked into the kitchen to hear Yuugi and Kiseki exchanging hair-styling tips over making breakfast.

Today they were to venture to the edge of Hogwarts' grounds. Yuugi tried not to trip over the growing roots and boulders the further away they moved away from the school; this was the first time he wore robes. He was far too fascinated by the way the extra layers of cloth swirled around him as he walked. Supposedly, aside from being quite the fashion statement, the robes actually protected them from certain spells. Apparently there were even warming charms imbued in the cloth! Yuugi couldn't pay attention to the smiles Ryou constantly sent his way.

Who knew that there was a completely different world out there solely based upon magic? It was a shame that the majority of the world didn't believe that magic existed. A part of Yuugi wanted to drag them into this world, but he knew that such a world needed to be protected. It was very likely that the outsiders would sully this place and attempt to control the magic for their own selfish purposes. Yuugi wouldn't put it past his former enemies.

Surely the magical world had its enemies too. From what Yuugi had gathered from the various conversations after the Sending yesterday, the wizarding hero that they sent was the world's last hope against some sort of Dark Lord. By the looks of Diagon Alley, the country wasn't at war… but who was Yuugi to judge? He hoped that he wouldn't need to worry about fighting. Hogwarts appeared safe enough.

"Hey! Over here!" Kiseki shouted, waving at the two boys. Yuugi and Ryou came to a stop on both sides of their mentor as they met three boys. Amun was the first, who bowed to all of them in greeting. Ryou's lookalike scowled at Yuugi but made no remark. His friend was right: he really did look like the spirit of the Ring. The wild white hair and hard brown eyes did indeed remind Yuugi of Bakura.

The third was a teen with long black hair which framed his face. He had high cheekbones and a long, thin nose. Black robes covered a deep green sweater and grey slacks. Two striking emerald eyes regarded both pairs of doppelgangers inquisitively.

"Yuugi, you've already met Amun. Ryou's lookalike here is Akefia. Vincent is the third," the female professor explained. "Vincent, Akefia, these are Ryou and Yuugi."

Seeing the question in Vincent's eyes, Akefia scoffed, "We are in no way related. As if I could ever be related to this weakling."

Yuugi caught Ryou bristling a little, but he didn't say anything. Kiseki spoke up for him instead. "What Ryou lacks in physical strength, he makes up for in wit and magical potential." She promptly whacked Akefia on the back of the head. Yuugi gasped, but the lack of an immediate attack told Yuugi everything was alright. "Five points from Slytherin for unnecessary slander."

"The fu—"

"Make that five more for profanity!" The sorceress placed a hand on her hip and leaned forward with a glint in her gaze. "Got anything else to say, Sennen-san?" Akefia shut up, causing her to smile. "Good! Now onto proper business. Come along now, boys~!"

They all followed behind Kiseki until they came to a large stadium. Yuugi wondered what sport it was used for, as he saw three high hoops at each end of the oval. It was obvious they weren't here for the sport, though, as a long rectangular stage was set in the middle surrounded by twenty students. Two men stood at opposite ends of the stage, appearing to be waiting for them. Both had shed their heavier robes and cloaks, leaving both in long-sleeved shirts and pants. The one on the left was the mysterious man who had greeted them after the Sending yesterday. His silken purple blindfold fluttered in the wind behind him.

"Prompt as always," the other drawled. His entire attire was black and littered with tiny buttons which contrasted greatly with his pale skin. A large hooked nose and bottomless black eyes told Yuugi he was not to be messed with. Yuugi glanced to the side to look at Vincent. It wasn't really obvious, but if you looked close enough you could see the similarities between their face types and long hair.

"Some things never change, Headmaster," was the reply from the sorceress. After telling the teens to stay put, she hopped onto the stage. Kiseki turned to the man from yesterday. "Professor Sakurai, if you may?"

The blindfolded one nodded. "I welcome all of you. As you can see, there are very few of you present. You were chosen to attend this… exhibition based on a variety of factors, one being your innate Elemental ability."

"What is displayed from here on will not leave the vicinity," the Headmaster continued. His eyes narrowed into a glare, causing a violent shiver to shake Yuugi's spine. "We will know." Everyone gulped.

Just what horrors has this man been through? Yuugi thought. There were very few times when he had seen a look like his. The glare itself rooted Yuugi in place.

"Observe." At the command, a sphere of water formed above the Headmaster's open palm. "This is known as Elemental magic. Professor Sakurai, to my knowledge, taught the basics." He scanned the group of students. "Granger, explain."

A bushy brunette stood straight. A maroon robe sat over a grey female's uniform. "T-There are four main Elements: Air, Fire, Earth, and Water. With enough training and magical ability, each Element is able to be honed and specialized." The girl paused for a moment. "There is a fifth Element… spirit?"

"Are you asking or telling?" the Headmaster asked with a perfectly arched eyebrow.

"Don't be so harsh on them, Headmaster," Kiseki commented, waving a dismissive hand at the stern man. "Five points to Gryffindor! Darkness and Light come together to become a full Element. Alone they are powerful, but together they become a nearly impossible force." She walked over to Professor Sakurai and took his left hand in her right, despite his protesting. He tried to tug his hand away, but she just held on tighter, seemingly oblivious. "Don't be such a spoilsport," she chided. The woman cast a calm look over at the Headmaster.

The dark man across the stage moved his hands together with the sphere swirling between them. In a sweeping diagonal movement the sphere expanded and solidified into a sheet of ice which shielded his front. The Headmaster kept his hands loose and moving though the shield itself stayed immobile. He nodded at the pair across from him.

Professor Sakurai extended his palm outward. "Anima incursu!" he incanted. A gray blast of light burst forth, rushing forward to strike the shield. The impact created a loud thud, small cracks forming in the shield. However, the wall didn't shatter.

Against a blast like that, shouldn't it—Yuugi thought but cut himself off when he realized what the Headmaster had done. In the wake of the blast he had caught the attack, which could explain why his arms kept on moving. The grey light swirled ominously within the ice shield. Slowly but surely the ball was dismantled within, and as it shrunk the edges of the shield melted. Once the Headmaster felt that the blast wasn't harmful, he allowed the wall to fall into a puddle around his feet. Yuugi barely noticed a wince from the man. It was as if he was trying to hide his pain. Even his labored breathing was controlled.

"I think that's a good start," Kiseki commented with a nod at both men. "That was a display of the Element of Spirit. However, the incantation Professor Sakurai used was similar to what Vincent used in the Great Hall the other day. Each one of you has an Element lying dormant within you. Whether or not we can tap into that power will be determined today."

Professor Sakurai was finally able to shake Kiseki off of his arm. He brought his hands together, massaging the one she had grabbed. "The Headmaster also summoned the two of us for this purpose: to work with him and the other heads of house in order to privately tutor those of you who can access your Elemental magic. The best way to check is with a simple spell modeled after the one I used. We shall break off into small groups. Slytherins and Ravenclaws report to Headmaster Snape. Gryffindors and Hufflepuffs, to me. At the end of this session we shall conduct duels using your newfound abilities."

Duels? Yuugi shook his head. Obviously they weren't the same duels he was used to. There were no cards, no summoning.

The Headmaster's glare returned after he had a few moments to gather himself. "As some of you may be wondering why such 'Dark Magic' is being taught on Hogwarts' grounds, allow me to remind you of the Missus ceremony. Light magic such as the ceremony is still considered Elemental magic. It is not what society deems the magic to be. It is how you use it which determines how 'Dark' it is. We are at war. The lines between Light and Dark blurs even moreso during these times."

"Well, it's obvious whose side you're on, Death Eater!" a fiery redhead shouted. By the way the Headmaster stiffened and the other students fell quiet, Yuugi gathered that the Death Eaters weren't a good group.

In a flash a band of white wrapped around the boy's head. His hands came up to try and tug the band of light off. Try as he might, he couldn't. The brunette girl who answered earlier was pointing her wand at the boy and muttering what Yuugi assumed were countercurses. Yuugi looked back onto the stage at a tapping noise. He saw his mentor tapping an ivory wand against her right palm. A look of pure disappointment laced through her features.

Little by little the others noticed the woman's obvious fault. Only when the boy stopped struggling did the Headmaster speak from behind her. "Watch your tongue, Weasley," was the low growl. "You have already been suspended. Only by the graces of the new professors are you even here."

"I'm reconsidering," the Magistra hissed in a cold voice. "The band will fade by dinner. Go." A flick of her wand caused the boy to yelp. The redhead tried his best not to look even more ridiculous as he ran toward the exit. Granger reached out as if to follow, but she relented.

The students parted like the Red Sea as Kiseki hopped off of the stage and walked over to Yuugi and Ryou. Her normal smile returned by the time she reached them. "Don't worry, Yuugi," she assured. "Nothing the boy didn't deserve. Trust me, Headmaster Snape would have subjected Mister Weasley to a much worse punishment." Kiseki winked. "Let's be glad that you didn't see that. Now, I have to help supervise because I know someone here is going to injure themselves. Ryou, would you like to help me?"

The other apprentice nodded, leaving Yuugi a bit lost. What could he do then? Aside from the one music lesson, he didn't know anything. Seemed like this would be practical healing. I'll be holding them back if I stay, but how else am I going to learn? Professor Tamiya reminded him repeatedly that he couldn't use any practical magic right now. He nibbled his bottom lip, averting his eyes away from her.

"As for you two," the woman continued, looking at Amun and Akefia, "You can stay or leave. Sakurai-sensei just wanted to make sure you two got some fresh air."

"Not worth my time," Akefia said with an eye roll. He turned and disappeared in a mist of shadows.

"Perhaps," Amun suggested, "I can watch over Yuugi-kun while you and Ryou-kun work on the practical aspects of Light magic? I think we can both agree that Yuugi-kun isn't up for anything strenuous yet." His crimson eyes peered over at the now-blushing teen. "If that's okay with you, Yuugi-kun."

Why does he have to speak like I'm not even here? Yuugi asked himself with a frown. He released his bottom lip and glanced up through his blonde bangs. He met Amun's eyes, filled with concern. Yuugi's answer was a tiny shrug. "I could bring Yuugi-kun around the campus afterward?" Yuugi continued to redden beneath the crimson gaze. Alone?! "Unless you would rather him accompany you both. I refuse to interrupt any lessons."

Kiseki's smile only grew at that. "Perfect! Since Hogwarts is such a large school, why don't you show Yuugi around the outer grounds and the Astronomy Tower later? This isn't the best time for a practical lesson in healing, anyway. You still need to recover."

Yuugi could only dumbly nod. "Remember, Yuugi, conflicts of the heart are detrimental," he heard as they split. Like the other day his mentor's voice came from everywhere at once. It didn't look like anyone else heard her either. Gulping, he resigned himself to accepting the telepathic message.

The emerald-eyed boy walked up to the two of them. He waved a slightly tanned hand at them. "Mind if I join you two? Professor Tamiya's gonna kick my ass if I try anything today."

Amun placed a palm on his forehead and sighed. "You should have known better than to have experimented during Defense Against the Dark Arts since your core was so weak from my summoning the other day." He opened an eye to look at the other teen. "Sometimes I wonder if you are truly are a Slytherin or if you are a lion in a snake's skin." The comment seemed to unnerve Vincent, as the wizard shivered.

There were so many words in there that Yuugi had to really think about. Defense Against the Dark Arts seemed like it was one of the classes offered here. Slytherin was one of the four houses that students could be Sorted into upon their arrival to the school. According to Hogwarts: A History, apprenticeships were different. Since discipuli were not normal students of the school, there was no need for them to be placed into houses. Discipuli were expected to room with their Magister or Magistra, eat meals with them, and study with them. During the small amount of free time that they had, he and Ryou could interact with the other students in extracurricular activities such as this.

The three followed the group of green and blue-clad students as they walked over to the Headmaster. He had since donned his robe, and the mass of black served to make him look even more intimidating. They billowed behind him in the wind like a pair of bat's wings. This greatly contrasted his ghostly skin. Is he even human? Yuugi thought to himself. There was always the possibility. Maybe he was some kind of vampire.

The Slytherins gathered to one side, and the Ravenclaws – Yuugi could tell by the bird crests – on the other with Amun, Vincent, and Yuugi in the middle. The Headmaster's cold eyes scanned over the groups. He sneered at the Ravenclaws. "Your books will not help you here, Miss Patil!" A flick of an ebony wand – where did he even get it? – snapped the book shut. The force would have definitely hurt the girl had the book caught her fingers. "Pay attention!" The witch nodded jerkily.

Yuugi nearly jumped back when those eyes settled on him. Amun's hand settled on his shoulder. "You need not worry about any interruptions from us, Headmaster Snape. Correct?" Amun spoke up, squeezing. Yuugi quickly nodded along with Vincent, though Vincent looked far from nervous. In fact, Yuugi didn't know what Vincent was so focused upon. He held up a stoic countenance somehow.

All the response Amun received was a glare and a terse nod. The Headmaster turned to the rest of the students. "Sheath your wands." All of the Slytherins complied immediately while the Ravenclaws hesitated. The Headmaster twirled his wand and shouted, "Expelliarmus!" The Ravenclaws' wands dropped to the ground and were summoned to the Headmaster with an accio. He sneered down at the wands before pocketing them in his long cloak. "As Professor Sakurai said, you will be practicing using the spell he used. The Latin for the first half of the spell will change depending on the Element that we suspect you harbor. Ravenclaws, your incantation will be ventus incursu while the Slytherins' will be aqua incursu. Our methodology is simple. If you are able to produce the element, you have the strength and control of a future Elemental."

With a series of complicated wand movements and spells the Headmaster transfigured a series of chairs in stone, wood, and metal. On each chair sat a bowl of fruit. Yuugi assumed correctly when the various textures would be used to gauge the students' strength. "You have fifteen minutes to practice on inanimate objects before the duels begin. Do not waste our time," the Headmaster ordered. "Begin."

Anima incursu – Soul shock

Ventus - Wind

Aqua - Water
