Author's Note: The title for this next chapter was originally going to be Mitaka's Curse. But I felt like this title was way more appropriate.

Chapter 3: Do or Die

Yuma was running through the halls of Heartland Academy as fast as his legs could carry him. He couldn't recall how he had gotten there, but he knew he had to run. There was something chasing after him, though he didn't know what it was, nor did he want to. All he knew was that whatever it was wished him some kind of harm. And whatever it was seemed to be gaining on him. He could hear the thing gliding through the halls as if it had wings.

Everything around Yuma was grey as though it was cast in an eternal twilight. The school looked as though it had been long abandoned. As Yuma ran, he was not only running away from the thing that was pursuing him, but he was also looking for something, or rather for some one. Though he didn't know whom this person he was trying to find was. The only thing Yuma knew for sure was that this person was very important to him for some reason.

As Yuma turned a corner, he glanced back and caught a glimpse of what was after him. It looked like a black shadow that had an almost human shape, along with great wings and a pair of glowing golden eyes. Yuma looked away from the thing tried running faster. He made a left, and to his horror reached a dead end. He heard the shadow land right behind him, and against his better instincts he turned around. The shadow took the form of Samantha, who was completely nude.

Yuma began to back away towards the wall behind him. Though he found Samantha to be a very stunning girl, he could sense something very dangerous about her. Samantha meanwhile began to advance on him as she licked her lips. She was like a cat that had just cornered a mouse. Yuma desperately looked around for some avenue of escape but couldn't find one. He was trapped and he knew it. In moments Samantha had him pinned against the wall.

"It's useless to fight this." Samantha told him. "Just relax. I know you're gonna enjoy this."

Yuma suddenly found that his body seemed to be frozen. Samantha moved in to kiss him, and try as he might, Yuma could do nothing to avoid the kiss of death that was about to come.

Yuma shot up in the hammock that served as his bed. The sudden movement caused the hammock to tilt and he fell hard to the wooden floor below him. Yuma groaned with pain as he got back to his feet. As Yuma cricked his spine back into place, he couldn't help but think about how real the nightmare he had just experienced felt. He decided to go splash some cold water on his face to try and shake it off. A bit later down in the bathroom as he looked at himself in the mirror after splashing himself with water from the sink, he suddenly felt like his chest was on fire.

Upon removing his shirt, Yuma was horrified to see a hideous mark that looked like it was burned onto the center of his chest like a brand. The mark was a single vertical line that split at the top into two curved lines like the top of a heart. Beneath both curved was a dot above a small almost diamond-shaped mark. The skin all around this mark was red and flaking as though it was infected. And whatever the infection was seemed like it was spreading.

Morning came, overcast by grey clouds just like the day before. Yuma had managed to drag himself to school despite not getting a full night's sleep. He hadn't been able to get back to sleep after the nightmare and finding the mark on his chest. Yuma had tried to tell his older sister, Akari about the mark, but for some reason he couldn't bring the subject up in front of her. It was as though some force had prevented him from speaking of it. As the first bell rang, Yuma tried to put the events of the night before out of his mind and headed for class.

"Hey Yuma." A voice spoke from behind, causing him to jump.

Yuma turned around, and standing behind him was a young woman about his age with hair that was red on top and pink on the bottom. He recognized this young woman as Anna Kozuki. Though Yuma and Anna didn't normally hang out together, they had been on friendly terms with one another ever since Anna had transferred to the academy two years ago.

"Hi Anna." Yuma responded. "What's up?"

"You doing anything later this afternoon?" Anna asked.

"Not really. Why?" Yuma asked back.

"I thought you and I could go out somewhere after school." Anna answered.

"What, you mean like… like a date?" Yuma asked.

"Well…" Anna began, looking away with a slight blush. "I guess you could say that's what this would be."

"So… are you asking me to be your boyfriend?" Yuma asked as his own face turned a bit red.

"Look, it's not like I'm proposing marriage here or anything." Anna told him. "But I haven't really been in that sort of relationship for a while, and I know you probably haven't had a girlfriend ever. And… the truth is I've kinda had my eye on you lately. So all I'm asking for is one date, and we'll see how it goes from there. So how 'bout it?"

"Well… sure. Why not?" Yuma agreed.

"Great. I'll meet you out in front of the school at the end of the day." Anna told him. "You better not keep me waiting." With that, Anna quickly went off to her own classroom.

Yuma headed for class as well. As Yuma walked through the halls, he was overcome by a strange feeling. He didn't know why, but he felt like he had just betrayed someone.

Kotori let out a yawn as she walked out of the classroom to head for lunch. She had stayed up until almost 2:00 AM trying to improve her deck using cards that Kaito and the others had given her. Many of the cards Kotori had been given were cards that she had seen Yuma use hundreds of times. Of course Droite had warned Kotori against trying to imitate Yuma's deck, so Kotori picked the cards that she was most familiar with and used them to try and improve her own. Kotori hoped very much that the deck she had put together in the end would help her to save Yuma.

As soon as Kotori reached the cafeteria, she spotted Samantha sitting by herself at one of the tables. Seeing it as an opportunity to get some answers, Kotori headed immediately towards her.

"Mitaka!" Kotori spoke, getting the redhead's attention.

"Well, I was wondering when I'd run into you again." Samantha calmly responded. "If you don't mind, I'd like to take the conversation we're about to have to somewhere more private."

"Fine with me." Kotori agreed.

With that, Samantha led Kotori out of the cafeteria and into the nearest girl's restroom. Once inside, Samantha took a quick look to make sure they were alone.

"Okay. If this is about a rematch, I should probably warn you that you only won yesterday because you got lucky." Samantha told her.

"I know that, and I didn't come to duel you right now." Kotori replied.

"Alright, then let me guess. You want to know how to save your precious Yuma and change everything back to normal." Samantha deduced. "Am I right?"

"There's that, and I want to know what you did to Yuma." Kotori told her.

"Okay, that's as good a place to start as any." Samantha replied. "I put a little curse on Yuma, one that if something isn't done soon will kill him. It'll also kill the Envoy of Astral World."

"Then what do I need to do to break it?" Kotori asked. "There is a way, isn't there?"

"Of course there's a way for you to break the curse." Samantha confirmed. "You have to give yourself to Yuma, in a way that you haven't done before."

"What do you mean?" Kotori asked.

At this, Samantha chuckled and shook her head. "Oh you are just priceless, birdie-girl. I'm sure it'd be obvious to anyone else, but for you it looks like I'll have to spell it out. You have to screw Yuma in order to save his life."

"You mean…" a startled Kotori began as her face turned bright red. "You mean Yuma and I have to…"

"You have to have sex, yeah." Samantha confirmed. "If Yuma doesn't get laid in the next five days, counting today, he's going to die a very painful death. First his balls will explode, then his heart will. It's not gonna be pretty."

"But that's…" a flustered Kotori spoke. "I can't believe you'd do something like this!"

"Hey, that's the kind of girl I am." Samatha replied with a shrug. "It's do or die, birdie-girl. Meaning if Yuma doesn't do somebody in the next few days, he dies."

"I just can't believe it." Kotori spoke. "I never imagined I'd have to go that far to save him."

"Hey, if you're too chicken to get it on with him, that's your problem." Samantha told her.

"That's not it!" Kotori told her.

"Look, I don't care what little hang-ups you have. If you want to save Yuma, you'll have to get over them." Samantha continued. "Not that you really have a chance anyway, since our darling Yuma doesn't have a clue who you are now thanks to my little spell. It is a little bit inconvenient for me that you regained your memory, but it's not a big deal. It's still going to be easy for me to take Yuma from you."

"What do you mean?" Kotori asked.

"Well, if Yuma doesn't get it on with anybody in the next few days, he dies." Samantha answered. "But if he gets it on with me or any member of the little coven I formed, he'll become my eternal slave. Not only that, the Envoy of Astral World will still die and the Numeron Code will fall into my hands."

"That won't happen." Kotori confidently declared. "Yuma would never give himself over to someone like you, not matter what kind of spell you've put on him."

"Think whatever you want, birdie-girl." Samantha told her. "It won't change what's about to happen. Yuma's ass is mine, and there's not a damn thing you can do about it."

With that, Samantha left the restroom with a satisfied smirk on her face. Kotori meanwhile clutched onto the counter to keep herself from falling to her knees. She was simply overwhelmed by what Samantha had told her she needed to do to save Yuma, and she wasn't sure if she'd be able to go that far.

It was the middle of the afternoon as Heartland Academy's star athlete; Vince "The Flash" Ishida entered the locker-room with his fellow students. He had managed to work up quite the sweat during basketball practice. The blonde athlete stayed under the shower longer than the rest of his team. The sound of the water hitting the titled floor often helped him to unwind after a hard few hours on the court. By the time Flash finally finished, he found himself alone in the gym showers.

Just as Flash was finally about to leave, all of the showers suddenly turned on by themselves and a warm steam filled the large room. The steam died down a bit after a moment to reveal Samantha, who was standing before Flash wearing nothing but a smile. The blood instantly rushed to the athlete's manhood the moment he saw the redhead.

"Oh dear, this isn't the girl's locker-room, is it?" Samantha spoke as she sauntered towards Flash. "Oh well. I'm certainly not going to complain."

"Y-you're that hot exchange student, Sammy Warren!" Flash quickly realized. "What're you…"

Samantha quickly silenced Flash by placing a finger over his lips. "Now, now. You don't need to think about that sort of thing, big boy. All you need to know is that I'm all yours."

With that, Samantha put her right arm around Flash's neck and got on her toes to jam her tongue into his mouth. At the same time, her left hand moved down and began to rub his hardened rob. Flash quickly gave into his lust and let his tongue rub against the redhead's. Meanwhile his right hand moved to massage Samantha's perfect breast, causing her to moan into his mouth. When they finally broke for air, Flash grabbed onto Samantha's rear and lifted her up, allowing him to insert his rod into Samantha's womanhood. Samantha moaned and threw her head back as she quickly wrapped her legs around the blonde's waist.

"Don't hold anything back." Samantha told Flash as he began to buck his hips into her. "Just give it to me!"

On command, Flash plowed into Samantha even faster than before. As the redhead wrapped her arms around the athlete's neck for support, she dug her nails into her back. Flash was so lost in pleasure that he didn't notice when Samantha's eyes started to glow. Before long, Flash suddenly began to feel some sort of energy pulsing through his body, starting at his rod. He didn't know what it was, but he didn't care, as each pulse sent him to new heights to pleasure.

Suddenly a pair of angelic black-feathered wings sprouted on Samantha's back. Her body began to crackle with red electricity as her skin changed to a rosy pink. A thin tail with a point on the end like that of a demon sprouted on her rear, and her head grew a small pair of golden horns. A pair of spherical gems became embedded in the redhead's shoulders, and her fingernails became like white claws. Her face became like a mask that seemed to be lacking a nose and mouth. The left side of this mask became covered in gold.

Eventually Flash picked up speed as he finally felt Mitaka's inner walls tightening around his manhood. With one last hard thrust they climaxed at the same moment. As the female Barian came down from her orgasm, flash merely stood there with a goofy expression on his face, completely oblivious to all that was going on.

"I figured you'd be good with all the sports you do." Mitaka spoke. "Let's see if you're just as good as a duelist."

With that, Mitaka used the nail of her index finger to scratch the same curse symbol on Yuma's chest into Flash's forehead. The scratches glowed with an unearthly red light for a moment before they vanished completely.

The school day was nearing its end as Kotori stood on the roof of the school lost in thought. She couldn't believe the measures Samantha had told her she needed to go to in order to save Yuma from a cruel fate. Kotori simply wasn't sure she would be able to do what Samantha told her was needed to break the curse. In fact she wasn't even sure if she could tell Kaito and the others about this development. Of course Kotori had thought about finally making love to Yuma in the past, but she never felt like she was ready to take such a big step with him. But now, if Mitaka was to be believed, it almost seemed like the decision to give herself to Yuma had been made for her.

"Kotori Mizuki!" a voice spoke, causing Kotori to look. The green-haired girl saw Flash standing a few feet away.

"You're Flash Ishida, the school's sports star." Kotori identified. "What do you want?"

"It isn't what I want so much as what my mistress wants." Flash told her. "I've come here to crush you in a duel!"

"Hey there, birdie-girl." Samantha spoke as she walked out from behind Flash. "I found another opponent for you. Let's see how you do against him."

"I'm guessing I don't have a choice, do I?" Kotori assumed.

"The only way you're walking off this roof is past me!" Flash declared.

"Fine! Let's go!" Kotori agreed.

With that, Kotori and Flash both activated their D-Gazers and duel disks. Meanwhile Mitaka's left eye changed from gold to blue. In an instant the color of the surrounding area changed slightly.

"I'm going first!" Kotori declared as she drew her first card. "First I set two cards face-down. Then I summon Gagaga Girl in Attack Mode!"

Appearing on Kotori's side of the battlefield was a teenage girl with light-blonde hair and reddish-brown eyes. She had on a dark-blue outfit that included a conical hat with orange trim that curved forward. Around her neck was a long pink scarf, and her skirt had large pink diamond-shaped segments, and on the back of the skirt was a large pink bow. In place of a magic wand, the young sorceress carried a red smart phone with a large keychain that had two white skulls dangling on the end.

"I end my turn." Kotori announced.

"Gee, I wonder if she's set some kind of trap?" Samantha asked very sarcastically. "A five-year-old can read moves like that!"

"Don't worry, my mistress. I've got this in the bag." Flash assured Samantha before drawing his next card. "For my first move I play the Continuous Spell card, Fire Formation – Tensu! Then because I have a Fire Formation card and no monsters, I can special summon Brotherhood of the Fire Fist – Coyote!"

Appearing on Flash's side of the battlefield was a man with long black hair and a beard. He had on a dark-blue outfit with orange trim that was like that of an old Chinese nobleman. In both hands, the man carried a long black chain.

"A monster with 2000 ATK on the first turn!" Kotori exclaimed.

"That's right. And thanks to Fire Formation – Tensu, all of my Beast-Warrior monsters gain an additional 100 ATK." Flash revealed. "Meaning Coyote's ATK becomes 2100. Now, for my next move I summon Brotherhood of the Fire Fist – Bear in Attack Mode!"

Appearing next to Coyote was a muscular warrior wearing black armor with gold and red trim. A flame burned on the top of his helmet, and in his hands he carried a sheathed sword.

"Thanks to Fire Formation – Tensu, Bear's ATK goes from 1600 to 1700." Flash continued. "Now I use the effect of Fire Formation – Tensu to summon Brotherhood of the Fire Fist – Buffalo in Attack Mode!"

Materializing on Flash's side of the battlefield was another warrior with long curly black hair and a beard. He wore silver and blue armor with red trim, and on his helmet was a pair of small curved horns. In each hand, the warrior carried an axe.

"Buffalo's ATK rises from 1700 to 1800 thanks to Tensu." Flash continued. "With these three monster on the field, you're as good as toast."

"Nicely done, Flash." Samantha praised. "Win this duel, I'll reward you."

'It's okay.' Kotori thought as she took a gulp. 'I can use the Gagaga Dimension card I set to destroy Coyote. After that I can start to turn things around on the next turn.'

"Kotori!" a voice spoke inside Kotori's head. The green-haired duelist instantly recognized the voice as Astral's. "Do not use Gagaga Dimension's effect… on Coyote!"

'What?' Kotori responded.

"I attack Gagaga Girl with Buffalo!" Flash announced.

"I… I activate my face-down card, Gagaga Dimension!" Kotori quickly announced.

Just as Buffalo raised his axes to attack, Gagaga Girl became enveloped in a burst of pink smoke. The smoke cleared to reveal a silver and red sarcophagus secured by gold chains inside a rectangular metal frame. The front of the crown on the head of the sarcophagus bore the red symbol of the Gagaga monsters. The top half of Gagaga Girl was sticking out the front of the sarcophagus, while her legs were sticking out the back. Gagaga Girl had an indifferent expression on her face, as she seemed to be texting on her phone.

"Because I have a Gagaga monster on the field, Gagaga Dimension lets me summon another Spellcaster from my hand!" Kotori announced. "I use Gagaga Dimension to summon Gagaga Magician!"

The sarcophagus opened, and emerging from it was a silver-haired wizard clad in a black and red outfit similar to Gagaga Girl's. He wore a conical hat that curved forward and a black stocking covered the lower half of his face. On his left foot he wore a red knee-high boot, and on his right he had on a simple brown shoe with a chain coiled around the ankle that went up all the way around his waist up to the back of his head. Attached to the chain was a sort of belt buckle was a kind of gold ornament or charm. His shoulders were covered by pieces of red armor, and around his neck was a tattered red scarf.

"And now, the second effect of Gagaga Dimension lets me destroy an opponent's monster!" Kotori announced as the sarcophagus disappeared. "And the monster I destroy is… Brotherhood of the Fire Fist – Buffalo!"

Gagaga Magician aimed his palm at Buffalo while Gagaga Girl took aim with her smart phone. Both magicians fired an intense blast of blue light that vaporized Buffalo in an instant.

"You took out one monster, but I've still got two left!" Flash pointed out to Kotori. "Bear, attack Gagaga Girl with Flame of the Bear!"

"I activate the Trap, Gagaga Guard!" Kotori announced. "Thanks to this card, Gagaga Magician and Gagaga Girl can't be destroyed in battle this turn!"

Bear pulled out his sword and swung it through the air, sending a blast of flames at Kotori's monsters. The large flame took the form of a bear that slashed its claws at Gagaga Girl, only to strike a spherical transparent barrier. Kotori still took some of the flames though, and her life points dropped to 3300.

"Since Bear was able to inflict some damage, I can set a Fire Formation card on the field directly from my deck!" Flash continued. "Coyote! Attack Gagaga Magician! Flame of the Coyote!"

Coyote swung his black chain like a whip and sent a massive green flame at the Gagaga Duo. The flame took the shape of a coyote that attempted to bite Gagaga Magician, only to be blocked by the same barrier that blocked the bear. Kotori once again took part of the attack and her life points fell to 2700.

"You idiot! Why didn't you attack Gagaga Girl with both monsters?" an irritated Samantha asked.

"Relax, mistress. I've got everything handled." Flash assured her. "You said so yourself that the girl's a rookie. No matter what I do, beating her will be a piece of cake."

"Cocky bastard." Samantha grumbled. "If you screw this up, Flash, I'm going to give you pain the likes of which you've never experienced before! Got that?"

Flash flinched and took a gulp. "Y-Yes mistress."

"Good. Now get on with it!" Samantha ordered.

"I, uh… I end my turn!" Flash announced.

Kotori took a breath as she drew her next card. "I activate Gagaga Magician's effect and change his level from four to six!"

"Well that's unexpected." Samantha spoke. "I would've thought you were going to use those two magicians of yours to summon that Number."

"I've got another monster I can use to win this duel!" Kotori declared. "I activate Gagaga Girl's effect and match her level to Gagaga Magician's! Now I overlay both my level six monsters to Xyz Summon my own ace! Help me out, Magi Magi Magician Gal!"

A vortex appeared in the middle of the battlefield and pulled in the two magicians as balls of purple energy. Rising out of the vortex a moment later was a fair-skinned young woman with blonde hair and pinkish eyes, wearing a black curved conical hat with pink trim and a sleeveless black outfit with a short pink skirt and a short pink cape on the back. She also had on a pair of black boots, and in her hand she carried a short pink and gold wand. Orbiting around the female magician were two balls of purple light.

"Is that… the Dark Magician Girl?" a stunned Flash asked.

"Idiot. But then I guess I didn't pick him for his brain." Samantha quietly admitted before turning her attention to Kotori. "I have to admit I'm impressed, birdie-girl. That's actually a pretty decent monster you've just summoned."

"I now activate Gagaga Girl's other effect!" Kotori announced. "Since she was used for an Xyz Summon, I can reduce the ATK of a special summoned monster my opponent controls to zero! And the monster I choose is Brotherhood of the Fire Fist – Coyote!"

A ghostly image of Gagaga Girl appeared around one of the balls of light orbiting Magician Gal and fired a beam of purple light from her smart phone. The beam hit Coyote in the chest and dropped his ATK.

"Well done." Samantha praised. "You even realized that you couldn't have used Gagaga Girl's effect on Buffalo, since he was brought to the field as an additional normal summon."

At this, Kotori gasped. 'That's why Astral didn't want me to use Gagaga Dimension to destroy Coyote!'

"I'll admit that you're not bad for a rookie. But I'm still going to take you down!" Flash declared.

"That's where you're wrong!" Kotori declared. "No matter what you do, I'm not giving up until I find a way to save Yuma!"

Author's Note: Because Kotori only ever dueled one time in the anime, I decided to give her a completely new deck. I took a little inspiration from the episodes of the original series when Tea dueled the Big Five member and penguin-obsessed pervert, Crump and had Kotori use some of Yuma's cards along with some generic Spellcaster and Warrior support. She'll only be using the Gagaga monsters though, and none of the other sound effect named archetypes used by Yuma. For those who don't know, Magi Magi Magician Gal is a real card. The artwork for it was originally going to be used for just another Dark Magician Girl reprint, but somewhere along the line it was decided to use the artwork for a card that could be a possible evolved form to Dark Magician Girl. Personally I would've preferred a Ritual or Synchro Monster, but I'll take what I can get.

I'd also like to note a change I've made to this chapter as of May 16th, 2017. My friend DragonKnight15 recently reviewed this chapter, and he noticed that I made kind of a major error with the duel. I totally forgot that the Magical Dimension card that Kotori originally used required a tribute in order to activate. So as a quick fix, I came up with a new version of Magical Dimension known as Gagaga Dimension. Probably not the most elegant solution, but still a simple one.

Please review and let me know what you think.
