Fire melting twin ice

Summary: Seth and Seto are the coldest twins in existence with only their younger brother as a source of warmth. Due to the stress of their earlier life, their bond was breaking apart until both fell in love with the same girl. Who will she choose? Seth×Seto×Fem! Yami! LEMON!

The school bell of Domino High School for twins sounded off as its students rushed off to class. It was a rather warm day of early winter and there was no wind as various teens entered the large building. The school was one of the biggest ones in the entire Japan, and only twins triplings or more were allowed to go to this special school. It didn't matter if the siblings were identical or siamese. All that matters is that they are born blood relatives that have a difference of a few minutes in age between them.

Seeing as it is actually quite rare to see twins on a daily basis, this was the school were you can find hundreds of them. It was one of the most famous schooling facilities in the world and the students themselves were rather big in name as well. Their uniform was simple in comparison to that of other schools, consisting of only a blue school jacket and pants with a white dress shirt for boys and a pink blazer with a light blue miniskirt for girls along with a bow tie. So simple, yet it made many twins look irresistible.

The kids made a huge path in the hallways as two tall brunets passed through. These two boys of the age 18 were the two richest, most famous, most popular, most powerful and most handsome high schoolers in the entire world. Seth and Seto Kaiba were every girl's dream with a matching hight of 186 cm, long legs, muscular, lean built, long, powerful arms, big hands with long fingers and handsome faces. Both had short, neat brunet hair with bangs falling into their sharp, blue eyes, high cheekbones, strong jaw and sharp features. The only difference between the two was that Seth has a natural, Egyptian tan while Seto was as pale as any other ordinary Japanese person.

The two had been adopted by Gozaboro Kaiba when they were ten in order to provide their younger brother, Mokuba, a safe and happy childhood, but they knew it was impossible to be all candy and lollipops when a ruthless, successful business tycoon like Gozaboro was adopting two geniuses. Yes, both twins are very intelligent and skilled. At the age of ten, Seth has already been speaking twelve languages fluently and two more were good enough to help him survive in a foreign country. He loved history, chemistry and biology since he was able to read and he didn't make that big of a fuss over his reading options. Seto, on the other hand, knew fluently only nine of the languages his brother spoke and two more just good enough to orient himself on his own, but he loves physics, psychology, management, economy, lawsuit and things like that while he considers history and the past as nothing but worthless wast of the present. Given how tough their lives have been, Seth was supposed that even a little of Seto's old self has stayed,.

Ever since their parents died in a plane crash when Mokuba was barely five, Seto had somehow took the steering wheel of their lives and started fighting for the three brothers to stay together. It wasn't an easy victory and the fight has been ferocious over the years, but both brunets were proud with the fact that they were still together and that Mokuba was having a semi normal childhood. Seto had been the first to throw away his own when he realized that their aunt and uncle were planning to either just keep Seth and Seto, or shift off all three brothers to the nearest orphanage. Seth threw away his the first time he saw his uncle trying to slap Seto, but it was already too late then. Both boys had earned a black belt in judo up to that point and Seto had nearly broken the man's right arm beyond repair. Seth, although older than his twin by a few minutes, for the first time felt like a scared, helpless child until ye saw Seto's eyes. Ever since then, the Seto he had known was almost dead and it only got worse the day they met Gozaboro.

Seto had been studying the man in order to beat him in a game of chess so that they could escape. At the time Seth had thought it was a somewhat good thing and both he and Mokuba had left the younger brunet to his own devices. However, it almost developed into an obsession. Seto spent hours working on strategies and psychological ways of thinking, and in the end it all payeed off. The day Gozaboro came to gift their local orphanage half the tournament money he won for staying the chess champion for three years, Seto challenged the man to a game of chess. The deal was that if Seto won, Gozaboro was to adopt Mokuba and the twins, no questions asked. However, upon seeing that Seto was the younger twin when Seth started protesting that it was like Gozaboro was buying Seto, the businessman demanded that both boys face him in a game and he will follow through with their agreement if only both of the boys win. Seto had been furious and Seth had a bad feeling that Gozaboro was trilled at seeing his rage.

In the end, after they played for three hours straight, both brunets won and Gozaboro had been furious. Seth had known a few things about his strategies, but Seto was the one that had fully humiliated the man. He had won in less than 28 moves and it had shocked all present. Seth always new that Seto's ambitions were going to take his brother far, but this was something not even he was expecting.

Gozaboro had kept his word and the three brothers moved into the mansion not a week later.

That was when life for the twins really started becoming hell. Gozaboro was a prideful man and he was furious with two kids were the ones that had defeated him in his favorite game. He had done an extensive research on the twins and found out how such geniuses had ended up in the little rat hole as well as to why they had stayed there for so long. He made sure to use it against them at every opportunity, but Seto had already decided that the past was meaningless. So for Seto, Gozaboro had to become creative.

The old bastard made Seto wear a dog collar and tried to strip him of his pride, but the young boy held on to it as if it was the last thing he truly felt was his. Seto grew colder with each passing day and Gozaboro was very pleased to see that it was also affecting Seth. It awoke the older twin's usually dormant hatred and Gozaboro nurtured them both into becoming hostile weapon makers. Seto was throughly talented in the field of designing and Gozaboro always made him do new projects for a couple of hours of sleep or a decent meal. More often than not, it was for the purpose of Seth and Mokuba not being returned to the orphanage.

Seth found out this only after two years of such treatment. It had been after one of their fighting lessons, when everything finally caught up with Seto and he passed out in his twin's arms. He had been mumbling in his sleep something about not wanting to end up alone with Seth and Mokuba somewhere else and when Seth asked his, for the first time, unguarded brother what he meant, Seto accidently told him everything before going still.

Seth still remembered th boiling rage he had felt upon leanrning of such a thing. After he had made sure his brother would get a few hours of sleep and told Mokuba to stay beside him, Seth had stormed into Gozaboro's office and demanded that he left Seto be. What the man had told him still made his blood freeze in his young veins.

''I'm afraid I can't do that,'' He had said. ''Seto is my future heir. He has survived everything I threw his way and he is far stronger than anyone I have ever seen. The darkness of his hatred is so immense that it trills me. I want to make him be the weapon of ultimate destruction, and he will become the new emperor of this modern world. I will not give him up, my precious weapon.''

Seto found out that he had talked with Gozaboro and the brothers got into a fight. It had seriously worried Mokuba that his Nii-sama and Onii-sama wouldn't speak to each other, but eventually Seto seeked them both out. The twins made amends, but it had been a full year since the last time they had spoken properly to each other. Seto wanted to believe that their bond could withstand it, but Seto was far to unpredictable. At one point, he had seriously feared that Seto was only using him and Mokuba to get Kaiba Corp, but after the hostile takeover, Seto put Mokuba for Vice President and he shared his position as CEO with Seth. Seth had relinquished most of the control to Seto, since it had been him that got more lessons on company business, and he settled for smaller jobs that will help Seto out. Mokuba was more than happy to help his bog brothers out and the three had been relatively peaceful since then.

However, there were always hardships along the way and now their main partner was teaming up with their board of directors in order to take over the company. Despite Seto's knowledge of Kaiba Corp and all its previous business, the board wasn't all that happy with him turning the once weapon-making company into a gaming industry, despite the raise in profits. The old geezers had betrayed Gozaboro and were now betraying them.

Seth sneaked a glance at his equally stoic twin as they settled into their seats. Seto immediately took out his laptop and started working on trying to keep their company and Seth sighed as he took out his book. This was becoming a routine as of late. They were always one of the first students in the classroom and Seto usually had a book for himself. They only went to high school to set an example for Mokuba, even though they more often than not left before the final bell. But ever since Pegasus and Industrial Illusions started the attempt at takeovers, Seto was exhausting himself with work. Seth could tell that Mokuba was starting to worry and he knew that his younger twin could not keep this up for much longer.

A few minutes later, the classroom was almost filled up when a group of friends noisily walked in. Seth looked up just in time to see eight kids walk into the classroom. The tallest of the group was a pointy-haired brunet, whose best friend was the blond beside him. There was only one girl, a bubbly, blue-eyed brunette and there were a set of twins and triplings following them. One was three of albinos, the middle looking like the evil version of the younger, gentler boy, while the oldest looked like a tanned, darker version of the middle one. And the second pair was of two three-color haired boys, one with amethyst eyes and the other with sharp violet eyes. The older albino had wild white hair and brown eyes that turned gray at night, while the younger was a bit shorter and had an angelic face with gentle brown eyes. The shorter of the three'color haired boys had round eyes and resembled a baby panda when he wanted something. His older twin had sharper features and his sharp eyes were circled by thick, long eyelashes.

The three teens that were with the pairs of exotic twins were one of the few twin pairs that were separated in their classes. The only girl, Anzu Mazaki, had a beautiful twin who has white-blue hair and a deeper shade of blue eyes, while Tristan Taylor and his twin were separated due to their parents divorce so Hiroto went under the name Honda and was in a different class. Joey and Jounochi Katsuya were separated after the first week of the freshmen year since they were making to much problems when they were together, and since the school already had a hard time of dealing with Akefia Bakura, the oldest albino tripling, and his boyfriend, Malik Ishtar (the younger of the Ishtar twins that were in another class), they decided it was easier to just separate the two. Bakura Bakura was actually somewhat restrained by the youngest albino, Ryou Bakura, although he and his best friend, Marik Ishtar, still loved to cause chaos with their siblings.

Poor Ryou almost acted like a mother for the two.

Seth smirked as the two spiky-haired teens nod at him and he nudges his brother. Seto looks up long enough to realize why Seth was disturbing him and he nodded to his only two good enough opponents before turning back to work. Atem, the older of the Mouto twins that had a rather nice Egyptian tan, rolled his unique eyes as Yugi, the younger twin, just shrugged with a smile. As they took their seats, Seth could see them taking out the deck they shared and going over it since they knew from the previous day that Seto was going to challenge them. The two were the only decent enough duelists around and Seto respected their skills, even though they still couldn't' defeat him. Seth, himself, was a big fan of his brother's favorite game, Duel Monsters, after he had seen him playing it for hours or making his holographic projectors to make the game even more interesting. He often wondered how Yugi and Atem had managed to make such a strong deck but were never able to beat his twin. Sure, even with Seto's three Blue-Eyes White Dragons lurking around Seto's deck, the dragons weren't indefatigable and his brother often complained why the other twins didn't' play better.

Atem has been the closest one to ever defeat his brother, but Seto was still the Duel Monsters champion.

As the group of friends, Joey, who had a way of really annoying the Kaiba twins, started pursuing Yugi to duel him during the big break instead of Seto. Seth watched in fascinated anger as the smaller boy considered it for quite a few minutes before declining. The eldest Kaiba was disgusted to find that Yugi could so easily change his mind, but was reassured that at least Atem respected Seto like he should when he reprimanded Yugi for his behavior. When the older twin looked his way, Atem winked at Seth, just to get on his nerves. Seth felt his left eyebrow twitch and the older Mouto smirked in victory. Atem was the closest to a friend that either Seth or Seto got, but with how often they fight, no one would believe it.

Joey, after being turned down and reprimanded like that, tried to get the two billionaires railed up and Seth almost cursed when he saw that Seto's patience was wearing tin. It was the blond's pure luck that the teacher chose to come at that moment, or there would have been bloodshed.

The classes went normal for the rest of the day, but Seto was in no better mood after his brief duels against Atem and Yugi. It usually calmed the younger Kaiba twin, but today he just wanted to rip someone's head off and not care about the consequences.

Atem felt a tad bit bad at having to watch Seto like that. He and Seth reminded him a hell of a lot of someone he loved dearly, what with their brilliance and competitiveness. And she also wasn't as open as he and Yugi were, at least not since the tragedy five years ago. In the hopes that their uncle will finally find his other two sons after his wife ran off, Aknadin and Aknamkanon (their father) had went on a trip to Japan. They hadn't taken any of the kids, and it was a good thing, too, since their plane crashed somewhere above the Indian Ocean. Due to their parents death, Atem, Yugi and their sister were supposed to either move to Japan with their mom and grandpa, or stay as it was appropriate for the last of the royal blood of Egypt. Their father's family was as long as from the time of the Nameless Pharaoh, 3000 BC, and they are the only ones who have actual influence over the rest of the politics in the country. The Egyptian government had insisted that Set, too, stays, but his mother had demanded his immediate departure for Japan.

Having no choice in the matter, Set reluctantly let go of Atem's weeping sister as he boarded the private plane. It would seem that the boy was never destined to leave Egypt, as the plane exploded before it even took off the ground due to something flying straight into one of the engines. At the age of 6, Atem and his siblings have been left with only their grandpa and mother.

Yugi had cried for days at all the deaths and in such a short time, but he got over it. Even Atem found a way to live through it all with the help of their childhood friends, Mahad and his sister Mana (in whom Atem fell in love with) over the short time they have had left in Egypt.

However, that wasn't the case for their sister. She had been closest to both their father and cousin, and she had retreated into herself, only being the same girl they once knew when she played Duel Monsters. She was really good and it had been her that has built the deck Yugi and Atem are using now. Unlike the boys, she would work for weeks in their grandfather's game shop for only one card and she somehow formed a bond with them. Whenever Atem and Yugi wanted to use the deck, they had to ask for her permission, as they could never otherwise get any good cards and would lose rather easily. All three of the Mouto triplings had a deck of their own, but Atem and Yugi used their sister's whenever the duel is too important. Besides, it was the best balanced of the three and it had many possible strategies with the same cards.

As the last class of the day finished, Atem couldn't help but think that if his sister dueled against the younger Kaiba, it was bound to be one hell of a show. Of course, if she got over the biggest shock of all: the resemblance between Seth and Seto with Set. When they first saw the brothers in their first year in Domino High School, Atem and Yugi had spent the entire afternoon in a daze and they both actually broke down when they got back home. So many things they could have done with their cousin and all the things they had already done ... it had been too much. Yugi had even gotten sick.

Atem had been more than glad that their sister hadn't been there to see that.

His sister, as was already said, was the closest to their cousin. Set resembled the Kaibas greatly, but he had a darker tan and broader shoulders, or would have had if he had stayed alive, since he spent hours with Mahad of chasing Mana, Atem and his sister out in the desert. Yugi, although rather energetic himself, preferred to play inside so he was almost as pail as their grandpa, who hadn't been in Egypt in three years before the accidents. His hair used to be a shade lighter due to all those hours and days in the sun, but his eyes were the same as the two twins'. It would have crushed her if she had seen them just like that, without warning.

The only female Mouto sibling had returned to Egypt just a month before high school started and Yugi and Atem had been left on their own. It's not that they couldn't make friends, or that they were extremely bad at school ... It's just that she was the heart of the family and she knew how to make any situation better. Yugi and Atem didn't know how she did it, but she could probably tame a crocodile in seconds.

Now that he thought about it, she was exactly what the two bored billionaires needed to make their life a bit more exciting.

''Yo, Atemu-kun, what's got you thinkin' dat much?'' Siad teen snapped out of his thoughts as he realized that Jou and Honda had joined their group as they all walked back home. Looking down at Yugi, he saw that his behavior was worrying his little brother and it bothered him that the little boy had to worry about him when he was worrying about their sister as well. They hadn't heard from her in two weeks now, and that couldn't mean anything good.

Atem sighed. ''It's nothing. I was just thinking about home and stuff.'' That didn't mean much to their friends since Atem and Yugi had decided to go under their mother's name so they didn't have to deal with the whole 'celebrities/princes' thing. To Yugi, however, that meant everything and the amethyst-eyed teen frowned.

''Well, ya got nothin' ta worry about pal.'' Joey said as he slung an arm around Atem's shoulders. ''I'm sure it's still standin' in the same place it had been this mornin'.'' Anzu rolled her opal eyes at the silly grins on the blond twins' faces and just shook her head.

''Just ignore them, Atemu. I'm sure that everything is just fine.'' She said as she leaned closer to him. Atem shifted uncomfortably, knowing that the girl had a little crush on him, and it made Yugi snicker.

Atem shook his head as he decided that, no, it wasn't worth the trouble to chase Yugi down and tickle him for hours to get back at him. ''I didn't think that something bad was about to happen. If anything, I have a rather good feeling today ... '' He said as he trailed off.

They heard a tsking noise and Atem turned around to glare at Akefia as he and his brothers made their way towards them. ''Oh, is the Prince now psychic, too? I didn't know you were so multi talented.''

''Shut it, Akefia!''

Said albino smirked and was about to say something else when the black limo licensed KAIBA 1 stopped beside the curb next to them. The large group watched in boredom as the black window rolled down to reveal one Seto Kaiba and his brother. Before anyone could say anything, Seto gritted through his teeth.

''Get ready for tomorrow like you mean it! I will duel you both and if it is like it was today again, I swear I will kick both your puny Mouto asses!''

And with that, the last thing Atem and Yugi saw was an amused smirk on Seth's lips as the limo window closed and they drove off.
