Disclaimer: I do not own Yugioh or any of the characters, nor do I own Supernatural or its' characters. This is a work of fanfiction. I am attempting to keep the characters as close to their canon portrayals as possible.

This story is set in a mixture of the manga verse and the dub universe. I will be using the anglicized names for Yugi's friends, and Domino City will be located in the United States as this is a Supernatural Crossover. Yugi is still of Japanese descent, with his father and grandfather being Japanese immigrants to the U.S. and his mother being a natural born American citizen. I realize that it is canon that Yugi's father is supposedly away on business most of the time but, for my purposes, he will be deceased. The family business, you see.

The story itself takes place sometime after Battle City and will noticeably diverge from the actual storyline. This is my very first fanfiction so I hope you enjoy and will offer some constructive criticism. I feel like some parts of it may ramble a little so I'm trying to keep that to a minimum while still giving a sense of the characters' thoughts and feelings at any given time.

I hope you enjoy!

Chapter 1

It was a day like any other in the city of Domino, gaming capital of the world. The sun was shining, and the streets bustled with locals and tourists alike enjoying the pleasant weather.

Yugi longed to be outside as he gazed out the window of his Chemistry class. He was prone, much to the frustration of his teachers, to space out in class during lessons. However, he was a generally quiet and good-natured boy, so most teachers were inclined to gently encourage him to bring his attention back to the class with minimal embarrassment. Unfortunately for Yugi, though, the substitute for his Chemistry teacher was not so forgiving. The man in question, Mr. Frankford was, for lack of a better description, lacking in most of the best qualities a person can possess, being both temperamental and cruel. Disappointment and disillusionment in his own life had helped make him a rather hard man, though he couldn't have been much more than 40 himself.

The sudden and deafening slapping of a ruler on Yugi's desk brought the young man back to reality with a start. His wide amethyst eyes shot up to the towering Mr. Frankford with a hint of fear, and no small amount of embarrassment. The scowl on the substitute's face told Yugi immediately that he had made a mistake in letting his mind wander in the man's presence. It wasn't that he had intended to do so, mind you. Yugi was a generally respectful young man and he did care, at least somewhat, about his grade. Sadly, he found it quite difficult to focus in lectures and Mr. Frankford's voice was so monotone at times that it might put even the most dedicated students to sleep.

"What is your name, young man?" Mr. Frankford asked icily.

Yugi stood quickly and stiffly, mumbling incoherently. While recent events in Yugi's life had given him a great deal more confidence than he had once possessed, he still sometimes found himself exceptionally anxious, retreating into his shell when faced with embarrassment. With the eyes of every single person in his class on him, this was one of those times. Yugi felt his face heat up and he was certain he was now sporting an impressive blush. He desperately wished he had even one friend in this class, but the members of his small group of friends were all in different classes this period, making it impossible for them to offer any comfort or aid to him. It was a lonely feeling, needing to see a friendly face and finding none.

When Mr. Frankford's scowl deepened, Yugi cleared his throat and instinctively clasped the heavy golden pendant he wore around his neck. A wave of comfort washed over him and he spoke up more clearly this time, though his voice was still very quiet and he stumbled over his own name.

"Yu-Yugi Mutou, sir," he answered.

Mr. Frankford studied the young man before him carefully. The boy, he thought, looked like he might fly away with a strong gust of wind. His face was beet-red and he had the look of a wide-eyed deer ready to flee from danger. He was, for all intents and purposes, a wimp with strange, multicolored hair.

Mr. Frankford disliked the boy immediately.

"You don't seem to take your studies very seriously, Mr. Mutou. I can't imagine you'll get very far in life with your head in the clouds all day."

Yugi blanched at the words. Yugi knew his grades were not what they could be and, despite his success and genius when it came to gaming, he was more than a little shamed by his lacking grade average. Mr. Frankford, seeing on Yugi's face that he had hit a sensitive spot, pressed the issue further. "A boy like you really can't afford to be spacing out in the classroom, can he?"

Frankford was being intentionally unkind now, picking at what he was sure would be a sensitive spot for a young man of small stature who possessed a shy disposition. Though his face did not show it, the older man was enjoying picking on this runt of a student who seemed, at least to the substitute teacher, to have very little going for him. The kid was unusually short, and seemingly very timid. The world would eat him alive.

Yugi's heart sank as the older man's words sunk in, causing him to want to do nothing more than to hide under a blanket in his bed for the rest of the day. At the same time, however, he felt something stirring at the back of his mind. His other self, or rather, his good friend who he had come to refer to as Yami for lack of a better name, was stirred from his slumber-like state by the discomfort and embarrassment now radiating from little Yugi. The ancient Spirit of the Millennium Puzzle, which Yugi wore around his neck, was none too pleased to find that someone was causing Yugi distress.

A low, almost feral growl echoed in the back of Yugi's mind. He could feel Yami's irritation at the substitute teacherm and he felt the spirit of his friend bubble up alongside his own, offering support and righteous indignation for his current situation.

Yugi knew Yami would take control in a heartbeat, if he allowed him to do so, but Yugi did his best to reassure his friend that it wasn't necessary. Yami, being much like a protective older brother, would likely say or do something Yugi would regret and it would very possibly result in harsher consequences in the long run. Yami could be particularly harsh and aggressive with anyone who he felt was treating Yugi unfairly. It was better, Yugi thought, to let Mr. Frankford say whatever is was he felt he needed to say, and then be on with his life. After all, it wasn't the first time Yugi had been embarrassed like this and he doubted it would be the last.

Yugi, with his eyes downcast, accepted the berating words of the teacher with no argument. He could feel the frustration Yami felt at simply watching this scene unfold, however, he had promised not to take control of Yugi's body without permission. Though Yami's anger was quickly growing at the cruel words of Mr. Frankford, he understood that Yugi did have his reasons for not unleashing his wrath upon random people.

Even if those people deserved a good Dark Game.

Yami sighed internally and turned his attention back to his young friend.

/Do not let his words bother you, young one. He knows nothing of you and is unworthy of your notice./

Yugi felt his spirit lift somewhat at his companion's words. Yami always had a way of bolstering Yugi's timid spirit. The small teen, while very good natured and brave when it came to protecting his loved ones, undervalued himself immensely and rarely stood up for himself.

Yugi was glad that, even if he did not have his other friends with him, Yami was always by his side. It was odd to think that his closest friend was an amnesiac Ancient Egyptian Pharaoh who had somehow managed to trap his own soul in a tiny puzzle, but then, he supposed, life could take some unexpected turns. He imagined Yami never foresaw this particular turn when he was alive, either.

"Detention, Mr. Mutou. After school." Yugi snapped back to attention at those words and his heart clenched with the feeling of being unjustly punished, but he sighed and nodded.

/Asshole. Let me game him./

/Nope. Not worth it. He isn't very nice but he doesn't deserve a Shadow Game for not being nice./

The only response from Yami was a snort of derision. Clearly, Yami felt that being unkind to Yugi was more than enough justification.

Mr. Frankford, seeming to have finally lost his interest in harassing the young teen, returned to his lecturing, and Yugi did his best to at least pretend to pay attention. He sensed, rather than heard, Yami's sigh of frustration. He couldn't help but feel a wave of sympathy for his friend. Yami was, after all, another human being and he was rather unceremoniously forced to take up residence in Yugi's body. Yami had little to no autonomy and Yugi knew that fact grated on the Spirit. Yami had proven to be a bold and confident person of action, yet he was unable to act as he wanted due to his respect for Yugi's wishes and his shared body.

Yami was completely dependent upon Yugi for his very existence. He was exceptionally grateful to Yugi for allowing him to exist, mind you. When he assembled the Millennium Puzzle, Yugi had freed Yami from the shadows that had surrounded him for time beyond memory. Yami had devoted himself to keeping Yugi safe from then on, though he had caused quite a bit of harm in the early days after he first awakened. In fact, Yugi had been unaware of Yami's presence for some time and had not known of many of the Spirit's actions, though the blank patches of his memory had worried him to no end.

Things were much different now, however. Yugi and Yami coexisted alongside each other without issue most of the time, and had become close friends. They worked together to handle the multitude of dangers and issues that seemed to haunt the bearer of the Millennium Puzzle.

The bell rang, signaling that it was, much to Yugi's relief, time for lunch. Yugi swiftly shoved his book and notebook into his bag and was one of the first to slip out the classroom door. He wouldn't risk catching Mr. Frankford's attention again.

"Yugi!"

The familiar voice of his childhood friend, Tea, caused Yugi to pause in his path. A larger boy bumped into him roughly, with an exclamation of "Watch it!" nearly knocking the much smaller Yugi to the ground.

"S-sorry!" Yugi stammered as he did his best to navigate the now busy hallway to the side of his friend and crush. Tea was a very pretty brunette girl with bright blue eyes and a confident, if somewhat pushy, demeanor. She smiled warmly at Yugi, taking in his rather harried appearance. Yugi, who stood several inches shorter than her, seemed out of sorts today and she wondered what had caused the downcast look in his eyes.

She hated to see that look on his face. It didn't happen much anymore since Yugi had solved the Puzzle. The overwhelming confidence and pride of the Spirit within the Puzzle had rubbed off somewhat on Yugi and, while he was still a shy and gentle young man, she had delighted in watching him emerge from his shell to interact more with others.

Not having the words but sensing that Yugi needed some support, she gently placed her hand on his shoulder and pretended not to notice his slight and sudden blush at the contact. He was entirely too adorable, and she smiled inwardly.

"Come on, Yugi. Let's meet Joey and Tristan for lunch. My treat today!"

Yugi beamed at her, nodding affirmatively, all thoughts of his earlier encounter with the unpleasant teacher having left his mind.
