A/N: Glad you guys are enjoying this one! I hope you like reading it as much as I love to write it. Hoping to jerk some feelings in this chapter.

For all who are wondering what Kiseki and Keiichi look like, you can find them on my deviantart. I'm fenikkusu64 over there!

Edited 11-11-14: Took out some miscellaneous stuff.

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

The companion fiction to this is Divided in the Darkness, United in the Light, told from the Yuugiou characters' point of views. But, as I said, there is no need to read that story or know anything about Yuugiou 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 Harry Potter or Yuugiou/Yu-Gi-Oh. I just own Keiichi and Kiseki. Leave my OCs alone. D|

Chapter 6: Quiescere (To Rest)

It would be safe to say that Snape had never experienced something like that before, even in his line of duty. Exorcisms were common in the wizarding world due to the heightened belief in the supernatural, but this… It was almost as if all of those cheesy Muggle horror movies had some backing to them. The way Vincent moved was, to be quite blunt, unnatural. And the way he screamed when Keiichi first latched onto those shadows reminded Snape very well of a banshee.

Snape shook his head when he saw Keiichi inch closer to the door. "Miss Tamiya most likely used the Muffiato spell. Your eavesdropping will do nothing to help you," he explained.

Keiichi crossed his arms and turned to the man. "Old habits are hard to break, I suppose. I cannot be surprised, however, seeing as she is an associate of yours." He leaned back against the doorframe. "You cannot fool me with that supposed emotionless mask of yours. You have questions, and I possibly have answers."

The Headmaster's obsidian gaze flickered from the prone teenager to the Dark Elemental. "Is he your Discipulus?"

"Was. I cannot teach him anymore than I already have. There was only so much I could do while within the Realm of Shadows," Keiichi explained. "When I extracted Osiris' shadows, I sensed the remnants of an Impulse."

"Yesterday morning, in the Great Hall," Snape replied with a nod of his head. "He… He interrupted a caster of the Cruciatus curse."

A smirk came across Keiichi's face. "You mean he saved you."

Snape stood with a start. "I've endured curses far stronger than those at the hands of Death Eaters! Are you saying I couldn't have managed on my own?"

"Have I hit a soft spot, Severus?" was the tease. Keiichi pushed himself away from the door and stood right in front of the current Headmaster. "I did not mean to incur your irritation. I was merely… rephrasing what you apparently cannot say for yourself." He took a step back and turned around, his cloak swishing behind him. "One aspect hasn't changed over the years, and that's your pride. I suggest you work on that."

Snape's fists clenched at his sides. How dare he mock me…

Keiichi shrugged off the glare on his back. "I have my own business to attend to, Severus. Alert the Healer if there is any change in Vincent's condition." He walked out, leaving Snape with the unconscious Lightning Elemental. Seeing no way out, the Headmaster settled in the chair closest to the bed.

Dozens of questions ran through his mind, but one stood out far beyond the rest. Who are you? Of course Snape didn't expect the boy to answer now, but he would get the answer sooner than later. He frowned. Why did this boy seem so familiar to him? Something tugged at his supposedly-non-existent heart strings as he saw the shallow risings and fallings of the boy's chest.

Perhaps it was his appearance. Although he looked like Snape, he wasn't a carbon copy. His face was more heart-shaped than rounded like him. His ears were smaller, and his lips were fuller. Vincent was also quite short compared to Snape.

Again, there is no possible way he could be my son, Snape attempted to convince himself, in vain. Not when he has Lily's features. She and Potter were the ones who married.

"Hey, Sev?"

"What's up, Lily?" A much younger Severus asked as they lay below a huge weeping willow. Its seeds spun around them as if doing pirouettes on an invisible stage no one could see.

"I know it's random, but if you ever had a kid what would you name it?"

Snape suddenly sat up and stared at her. "Of all questions, why that one?"

Lily glanced his way and pouted. "Just answer the question, Sev."

Still not satisfied, Snape crossed his arms. "If you must know… If I had a son, I would name him Adrian."

Lily laughed, the sound easing some of Severus' annoyance away. "Do Latin names run in the family?"

"On my mother's side, yes."

"Of all the Roman emperors, why Adrian?"

"Hadrian was the adoptive son of Trajan. He travelled through the empire to strengthen the frontiers and encourage learning." Severus shrugged. "It sounds good, too."

Lily stood up and poked his shoulder. "Anything sounds better than Severus. It's like whoever named you thought you were gonna grow up to be a grump."

Snape frowned and ignored the gibe. "Mother was right."

Lily frowned back, the fire in her emerald eyes dying immediately at the comment. "Don't say that, Sev."

"Why the bloody hell not?" the boy hissed. "You're my only friend, Lily. Your sister hates me, everyone at school hates me. Just because I don't look or act like them, because I'm different." His black eyes gazed fondly at the willow seeds. "I'd rather be different, anyway. Muggles are boring. Just think, Lily… On September 1st we'll be heading to Hogwarts! There are going to be so many more magical students like us!"

The smile that bloomed on Lily's face nearly made Snape's heart stop. "You should smile more, Sev. You'll thank me when you're older!"

Wait. Snape reached into his robes and retrieved a small stack of papers. The name "Vincent Adrian Evans" glared up at him. He clenched his fist and threw the ball of parchment against the far wall. Stop hoping for a small miracle. You know those don't exist. Snape buried his head in his open palms.

"'Kay!" The toddler stood up and pressed a sloppy kiss to my cheek. "Love you, Dada."

After a few moments of silence, I replied. "Love you too, scamp."

But why did still dare to hope?

The next day, the Carrows were found dead in their respective offices.

Only Snape's glare stopped the students from cheering during breakfast. A wandless sonorous allowed the Headmaster's voice to boom over the crowd. "Due to the… unfortunate end of our two newest teachers, I have taken the liberty to find replacements. I would like to introduce Keiichi Sakurai and Kiseki Tamiya who will be teaching Defense and Muggle Studies, respectively."

Keiichi sat to Snape's right. He nodded to the students and crossed his arms. His black attire was only offset by a shirt the same shade of crimson as blood. A purple piece of silk wrapped around his eyes, obscuring them from view. Jet black hair spilled over his shoulders, framing a sharp tanned face.

To next to Keiichi, Kiseki waved to the students. Today she was robed in a simple lilac off-shoulder dress. She allowed her hair to cascade down her back in small waterfalls. The woman looked like she wanted to say something, but she refrained. Kiseki frowned at the Gryffindor table. When Snape looked over there himself, he found many of the older boys ogling her. Of course the lions were the most transparent.

It took all of Snape's will not to burst out into laughter in the middle of the Great Hall. He had a reputation to upkeep, after all. However, the corners of his lips twitched upwards in the barest remnants of a smile. Seeing that, Kiseki's frown shifted into a grin. She turned toward the Headmaster with a nod and began to dig into her food.

When the students were dismissed, the Headmaster and the two newest professors walked out through the staff door. Kiseki folded her hands behind her back and looked over at Snape. "You know, you can stop the cold countenance thing around me, Severus," she mentioned with a pout. The woman ran ahead and turned to the men, walking backwards. "You can just ask me how he's doing. Or is that insufferable pride of yours getting in the way again?"

Keiichi chuckled, "I believe it's the latter, Miss Tamiya."

The girl looked affronted. She took a few steps forward and whacked the blindfolded one on his bicep. "No need to be so formal, Mister Tough-Guy! Call me Kiseki or plop an honorific onto it! None of this last name stuff. Not when we're alone like this with Severus, 'kay? I personally get sick and tired of hearing that kinda stuff all of the time."

"I kindly ask if you would cease calling me that childish nickname," Keiichi continued, ignoring the jab.

Kiseki pouted. "Pfft. You're no fun." She turned her attention back to Snape. "Anyway, Vinvin should be fine. I don't have class for a few hours, so I'm going to check on him. Wanna come with, you two?"

The Defense professor shook his head. "I apologize, but I must prepare for my first class of the day. With the Dark Lord's presence growing ever stronger, I may need to adjust the curriculum. My first class is in twenty minutes."

"Aww, okay." Kiseki paused at the top of the stairway on the third floor. She cocked her head to the side as she regarded the two men. "Hey, do you have class with the Slytherin Seventh Years today, Sakurai-sensei?" A curt nod. "If it's in the afternoon, I can send Vincent to you. Just don't make him do anything too strenuous."

A pause. "I cannot guarantee that he will not use magic."

"And I never said that he couldn't use it," was the retort as Kiseki placed her hands on her hips. "Remember, I've read enough about you. I know enough to conclude that you won't put your own discipulus (student) in mortal danger. I just ask that you don't rough him up too much, or his recovery time will be extended." She cast a tempus in the air and nodded. "Well, I've gotta go. I'll leave you two to your own devices; come along if you want, Severus. I may need to ask you to brew some more potions for me." With that she turned with a wave and walked away.

Keiichi shook his head and whispered, "How on earth did you put up with that woman when you were younger? Judging by the amount of energy she has today, she must have been a handful."

The Headmaster shrugged. "In all honesty she wasn't quite this hyperactive when we were teenagers. It's been quite a few years since I've seen her, myself." He nodded to the Defense Against the Dark Arts classroom at the far end of the hallway. "Good luck."

The chuckle this time was low and dark. "Do not worry, my friend. If the students prove to be a problem, I will be able to… convince them otherwise." Snape couldn't help but wonder what exactly Keiichi was planning as they parted ways.

He felt like he was run over by the Knight Bus.

Vincent groaned as he returned to reality. His body ached in places he didn't know even existed. What greeted him was a large, sparsely-furnished room. He blinked when he realized blankets wrapped tightly around his form. Someone… tucked me in? Vincent shook his head. What happened to me?

"Awesome, you're awake!" came a feminine voice. Vincent turned his head to the side to see a young Asian woman dressed in some kind of medieval dress. Her long black hair was pulled back into two ponytails, one hanging from each side of her head. She smiled softly and placed a gentle hand on Vincent's forehead to prevent him from getting up. "Easy does it. You've been through quite the ordeal. Can't have you getting up too quickly, or the Headmaster will have my… head." She winced at the last sentence. "That sounded way too weird."

That made Vincent smile a little, regardless of his extreme fatigue. "W-what…" he trailed.

"I'm about to tell you that, but first let me introduce myself!" The woman bowed from her waist. "I'm Tam—oh right it's first names here first. I'm Kiseki Tamiya! I'm formally known as the Domina Mentis, an expert on Mental Magic. I'm also an experienced Light Elemental and healer. Even though I was brought in here by the Headmaster for a different reason, I was assigned to help you recuperate. Do you remember what happened?"

What Vincent didn't realize was that the pull of the Shadows in the Realm of Light was much, much more powerful. The Shadows meant for the Death Eater raced toward Vincent instead. "Amun!" the boy screamed as he backed up into the classroom's door. "Help me!"

"Damnit! Evans, get out of here!" was the equally panicked response.

Vincent could only scream as the darkness devoured him.

The newest Slytherin winced at the memory. "Amun summoned something from the Shadow Realm, and it thought that I was the intended target?"

Kiseki hummed. "Something along those lines. What really happened is that your heart is so pure that Osiris couldn't help but be attracted to you. Amun currently doesn't have full control over the Egyptian God, you see." She leaned back in her chair. "Don't worry, he's fine. He just needed some recuperation much like yourself. Do you think you can sit up a bit more so that I can check your vitals?"

"Er, sure," Vincent mumbled as he placed his palms flat on the bed. A bit of effort had him sitting up against the headboard.

The healer smiled again and waved a hand. A stethoscope appeared around her neck. "You're muggle-born, so you should know what this is. It's a stethoscope, and it magnifies sound," Kiseki explained as she placed the earpieces in. She gingerly tapped the scope's other end before placing it on Vincent's heart. "I know there are diagnostic spells, but this is much more accurate. Breathe in for me, nice and deep." And so Vincent did. She moved the scope to three more spots on his chest before checking his back as well. Kiseki sighed in relief as she banished the stethoscope. "Well, your breathing is much better than yesterday. You're not hyperventilating, that's for sure. The wheezing left over from Osiris' attack has dissipated."

She conjured a cup filled with warm water in one hand and a vial in the other. "It's a nutrition potion, Mister Evans. You're quite undernourished for someone your age… And it's not just from this summer."

Vincent froze.

"Trust me, I know first-hand what it feels like," Kiseki whispered, gazing straight into Vincent's eyes. "I know you don't know me personally, yet, but I'm hoping to fix that. If you need anyone to talk to, you can always talk to me. Or Sakurai-sensei; he was your magister at one point, no?"

"H-how did you know?"

"About your apprenticeship? Oh, that's easy, but that's best saved for another time. What I need you to do now is relax. You have class in the afternoon with Sakurai-sensei."

"What?"

A small smirk formed on Kiseki's lips. "Your first Defense Against the Dark Arts class won't require you to use magic, or so I've been told by the new professor. He's on strict orders to teach only theory. Besides, he can't get to all that he wants to in the first period with you guys; it's just not feasible." Kiseki pointed to herself. "And I'm the newest Muggle Studies teacher. Miss Carrow met an unfortunate… ending this morning."

Vincent blinked. "… what else have I missed?"

"Where do you want me to start?"
