Author's Note: Here it is, the final chapter of this story. And also the final Devil Number. I had originally planned to wait and show this Number off until the next story, but I decided to go ahead with a little preview of it.

Disclaimer: I do not own Yu-Gi-Oh! ZEXAL.

Chapter 20: Number 666

"We'll do this as a two-on-one duel." Alnia told Kaito and Droite. "Both sides will have 8000 life points to start off with. Sound good?"

"Fine with me!" Kaito agreed.

"Let's get this over with!" Droite responded.

With that, Alnia's red eye turned green and a golden blade-like duel disk appeared on her arm. At the same time, Kaito's outfit changed from black to white. As soon as Kaito and Droite's D-Gazer tattoos activated the sky changed from blue to red.

"I'll go first since I'm sort of at a disadvantage." Alnia announced as she drew her first card. "I summon Archfiend Tomb Builder in Defense Mode!"

Appearing on Alnia's side of the battlefield in a kneeling position was a humanoid demon with dark-grey skin and a skull-like face with red eyes and yellow teeth. He was dressed similar to an Ancient Egyptian and wore a white cloth on his head. In his hands, the demon carried a hammer and chisel.

"When I've normal summoned Archfiend Tomb Builder, I can add a Trap card from my deck to my hand." Alnia announced. "In the time of my former life, the pharaohs would sometimes have their tombs built with booby-traps in order to protect their rotting carcasses and any treasures they wished to be buried with them."

"So you were from Ancient Egypt in your past life?" Kaito asked.

"Yeah, but I wasn't royalty. I was merely a little peasant girl." Alnia answered. "You ever hear of a little village called Kul Elna?"

"Should I have?" Kaito asked.

"…I guess it doesn't matter." Alnia replied after a moment. "I set two cards on the field and end my turn."

"I'll go next!" Droite announced as she drew her first card. "I summon Swallowtail Butterspy in Attack Mode!" The orange and black-winged butterfly woman appeared on the battlefield. "Because I just summoned Swallowtail, I summon Blue Mountain Butterspy!" Droite's blue butterfly woman materialized next to Swallowtail. "Using both my level four monsters, I Xyz Summon Dead Star Butterfly Priestess!"

A vortex appeared in the middle of the field and pulled in Droite's two monsters as balls of purple energy. Soon after, Droite's white-haired butterfly-winged priestess rose from the vortex with two balls of purple light orbiting around her.

"I activate Butterfly Priestess' effect!" Droite announced. "By detaching an overlay unit, Butterfly Priestess can destroy one monster with lower ATK than her own! And of course the monster I choose to destroy is Archfiend Tomb Builder!"

One of the balls of light orbiting Butterfly Priestess entered the red gemstone on her necklace. The white-haired butterfly woman aimed her right hand at Alnia's monster and fired a purple ball of light at the demon. Archfiend Tomb Builder turned to dust upon being hit.

"Thanks, now I can activate Archfiend Tomb Builder's other effect." Alnia announced. "When Archfiend Tomb Builder is destroyed and sent to the Graveyard, I can set two Trap cards directly from my deck onto the field."

'Damn!' Droite mentally cursed. 'I just played right into her hands.'

"Go on, vampire girl. I know you can do better than that." Alnia told her.

"…Using Butterfly Priestess, I rebuild the overlay network and Xyz Summon Dead Star Papillon Dragon!" Droite announced.

A purple galaxy-like vortex appeared on the field and pulled in Butterfly Priestess as a ball of purple light. Rising out of the vortex soon after was a large black butterfly-shaped brooch with a purple gem in the center and two balls of purple light orbiting around it. The brooch flashed with a blinding light that cleared to reveal Droite's glowing purple dragon.

"Are you sure it's such a good idea to summon that monster?" Kaito asked Droite.

"No… but I don't think we can afford to hold anything back against her." Droite answered. "I'm getting a really bad feeling from Alnia."

"Yeah… me too." Kaito agreed.

"I set one card on the field and end my turn!" Droite announced.

Kaito drew his first card. "I activate the Spell, Photon Sanctuary! With this card, I summon two Photon Tokens to the field!"

Two balls of blue light appeared on Kaito and Droite's side of the field. Each ball had a set of three smaller balls orbiting around them.

"Both Photon Tokens have an ATK of 2000." Kaito announced. "So I now sacrifice them both to special summon the ultimate avatar of light! Come forth, Galaxy-Eyes Photon Dragon!"

The balls of light shattered and a red cross-like object appeared in Kaito's hand. Kaito threw the cross into the air and it exploded with a blinding flash of light. The light cleared and Kaito's glowing blue dragon appeared with a roar.

"Since you just summoned a monster, I can special summon Archfiend Tomb Guardian from my hand in Defense Mode!" Alnia announced.

Appearing on Alnia's field in a kneeling position was another humanoid demon with dark-grey skin and a skull-like face. He was also dressed like an Ancient Egyptian and had a golden helmet on his head. In his right hand, the demon carried a golden crossbow.

"When Archfiend Tomb Guardian is summoned using his effect, I can destroy a set Spell or Trap card on my opponent's field!" Alnia announced.

The demon fired an arrow from his crossbow at Droite's large facedown card. The arrow pierced the back of the card and caused it to shatter into bits of gold light.

"Photon Dragon, attack Archfiend Tomb Guardian!" Kaito commanded. "Photon Stream of Destruction!"

"I activate my Trap, Hate Buster!" Alnia announced. "When a Fiend-type monster of mine is attacked, Hate Buster destroys both it and the attacking monster and deals damage equal to the attacking monster's ATK!"

As soon as Photon Dragon fired a stream of blue energy from his mouth, Alnia's monster exploded into a black mist that sent a shockwave over the entire battlefield. Kaito's dragon was destroyed by the shockwave and the black mist knocked into Kaito and Droite, knocking the couple's life points down to 5000.

"So that's the big bad Photon Dragon." Alnia remarked. "I have to say I'm not really all that impressed. It's a good thing for you though that you didn't summon that dragon's Number form, otherwise you'd probably be dead right now."

"I still have one monster that can attack!" Kaito pointed out. "Papillon Dragon, attack Alnia directly! Photon Stream of Desolation!"

Papillon Dragon fired a stream of purple light from her mouth at Alnia. Before the attack could strike though, a black and grey Egyptian statue with a skull-like face appeared in front of the female Barian and blocked the attack. The statue shattered and sent back bolts of black electricity that struck Kaito and Droite, knocking both of them to their knees. Their life points had taken another drop to 3500.

"M-Master Kaito! Ms. Droite!" a worried Orbital 7 exclaimed.

"What did you do?" Kaito demanded to know.

"I used the effect of a little monster called Cursed Ushebti." Alnia explained. "When I'm attacked directly, I can discard Cursed Ushebit to negate that attack and deal damage equal to half the attacking monster's original ATK."

"She's been ahead of us from the start of this duel." Droite observed as she stood back up. "Meanwhile we've been unable to take even one life point off her."

"It's still your move, Tenjo." Alnia reminded him.

Kaito got back to his feet and glared at Alnia. "I set two cards on the field and end my turn!"

"Okay then." Alnia responded as she drew her next card. "I think it's time I wrapped this up."

Kotori was on her back as Yuma thrust into her at a hard but steady pace. Both of them were completely naked, their clothes scattered all around the sphere field. It wasn't anything like what had ended up being their first time, rushed, awkward and painful. This time Kotori was completely lost in the pleasure brought by the connection between her and Yuma. As time went on, the pleasure began to build. Kotori could feel herself coming close to the edge as her inner walls tightened around Yuma's manhood.

The green-haired girl wrapped her legs tightly around Yuma's legs and grasped onto his shoulders. Yuma took the signal and began to plow into Kotori harder and deeper. Another eternity seemed to go by, and Kotori felt like she would lose her mind if she didn't reach her peak soon. At long last though, Yuma and Kotori managed to hit their climax at the same moment. Kotori felt a warmth shoot into her as her own body shuddered from its own release.

As Kotori came down from her high, Yuma withdrew himself and lied down next to her on the invisible floor of the sphere field, pulling her close. Kotori cuddled tightly up to Yuma and wrapped her right leg around his legs to compensate for the emptiness now inside her.

"So, um… was that any better Kotori?" Yuma asked.

Kotori smiled and nodded. "That was wonderful, just like I hoped it would be."

"…You know, I think I could go again if you like." Yuma told her.

"Really?" Kotori responded as her face turned a deep red. "Um… okay, sure."

Yuma smiled and the two of them became locked in a deep open-mouthed kiss. When they finally broke for air, Yuma gently pushed Kotori onto her stomach. Kotori was content to let Yuma take the lead. Yuma stood up Kotori let out a small cry of surprise as he took hold of her legs and pulled her up, making it so she had to support herself with her arms while Yuma held her like a wheelbarrow. Yuma then pushed his hardened rod into Kotori's womanhood and began to buck his hips.

Kotori grasped onto the invisible floor of the field as best she could to keep herself from collapsing. Her breasts bounced beneath her as Yuma continued his thrusts. To Kotori, it felt like Yuma's entire body was on fire, and that fire was quickly spreading into her as well. Before long both of them became covered in sweat. Eventually the two of them felt themselves coming close to the edge again. With one final hard thrust from Yuma, they once again reach their climax in the same moment. Kotori let out a deep moan as Yuma hot essence shot into her.

Yuma withdrew himself and gently set Kotori down on the floor of the field. He lied back down next to her and pulled her close. Kotori nuzzled into him and quickly dozed off. Smiling, Yuma kissed Kotori on the forehead.

"I activate the Spell card, Shadow Trap Disposal!" Alnia announced. "By banishing two Fiend-Type monsters from my Graveyard, I can destroy two set Spell and Trap cards on my opponent's side of the field. So I banish Archfiend Tomb Guardian and Cursed Ushebti to destroy the two set cards you put out!"

Ghostly images of Alnia's two monsters flew through the air and struck Kaito's two facedown cards. The cards exploded into black mist that blew away in the breeze.

"I now activate my three face-down Tomb Trap Soldiers!" Alnia announced. "When activated, these cards become three level six monsters with 2000 ATK!"

Suddenly appearing on Alnia's side of the field were three identical grey Ancient Egyptian statues, each with a skull-like face. The statues all had glowing red eyes and held a saber in their right hand.

"This was her plan all along!" Kaito realized. "She was aiming to summon those three Trap monsters to the field!"

"Using my three level six monsters, I build the overlay network and Xyz Summon the ultimate monster of evil!" Alnia announced. "Come forth, Number 666: Archfiend Pharaoh Lucifer!"

A red galaxy appeared in the center of the field and pulled in Alnia's three statues as balls of red energy. The sky became covered in dark clouds and rumbled with thunder as an object rose out of the vortex. The object in question had three balls of golden light orbiting it and was made of brown stone. It looked similar to the lid of a sarcophagus. Carved into this lid were strangely shaped holes made to fit seven unknown objects. Before Kaito and Droite could fully contemplate this carving, the object suddenly exploded and created a cloud of dust.

The dust soon settled to reveal a new monster hovering above the field in the form of a humanoid demon clad almost completely in black armor with gold trim. The demon had a dark-grey skull-like face with sharp yellow teeth. His right eye was red, while his left eye appeared to be artificial and made of gold. The artificial eye looked like a strange version of the wadjet eye. On his head, the demon wore a gold and black headdress of a pharaoh, and on his chin was a gold and black fake beard that was also sometimes worn by the Ancient Egyptian kings. Hanging from his neck by a silver chain was a gold ring-shaped pendant with a triangular piece in the center that bore a symbol similar to the demon's artificial eye and five pointed ornaments hanging from the lower half. On the demon's back was a pair of large red-feathered wings, and in his right hand he held a gold scepter with a ball at the top that had two blades on the side and the same eye-like symbol as his artificial eye. Glowing in red alien writing on the demon's left shoulder plate was the number 666.

"So that's Alnia's Number." Kaito observed.

"It may have 3600 ATK, but Papillon Dragon can only be destroyed by Dragon-type Synchro Monsters." Droite reminded him. "We should at least be safe for this turn."

"I activate one of Lucifer's effect!" Alnia announced. "By detaching an overlay unit, I can take control of an opponent's monster until the end of the turn!"

"Crap!" Kaito cursed.

One of the balls of gold light orbiting Alnia's Egyptian demon entered the eye on his scepter. The eye of the scepter then began to glow with a gold light.

"By the power of the Millennium Rod, I bend Papillon Dragon to my will!" Alnia declared.

Lucifer aimed the rod at Papillon Dragon, causing the dragon's eyes to glow gold. The same eye-like symbol on the rod appeared on the dragon's forehead. Papillon Dragon roared and mindlessly flew over to Alnia's side of the field.

"Taste the fury of your own dragon, bitch!" Alnia told Droite. "Papillon Dragon, attack your master directly! Photon Stream of Desolation!"

Papillon Dragon fired a stream of purple light from her mouth at Droite. Droite screamed upon being hit and was knocked to the ground as her and Kaito's life points dropped to 500.

"Droite!" a worried Kaito called out.

"You've got your own problems, photon boy." Alnia told him. "Lucifer, attack Tenjo directly! Millennium Ruin!"

The demon pharaoh took aim at Kaito with the Millennium Rod. Kaito froze and looked as a ball of black energy cracking with gold electricity formed at the end of the demon's scepter. As the sphere grew in size, Lucifer fired it down at Kaito. Kaito was struck and cried out as his and Droite's life points fell to zero. When the smoke cleared, Kaito and Droite were both on the ground out gold. Both Lucifer and Papillon Dragon vanished and the sky returned to normal. A panicked Orbital 7 drove over to the side of his fallen master and his girlfriend.

"Well that was pitiful." Alnia declared before turning to look back at Mitaka. "And you actually had problems with these losers?"

Before Mitaka could respond, Vector and Alit arrived with Gilag, Mizael and Cathy. All five immediately stopped upon seeing Kaito and Droite on the ground and Alnia standing nearby with Mitaka.

"What the hell?" a stunned Alit asked. "What just happened?"

"Well, well. If it isn't some of Don Thousand's former pawns." Alnia observed. "I'm afraid you missed the show."

"Did Tenjo just lose to one of these two?" Mizael asked.

"If any of you want to take me on next, I'm game." Alnia told them. "But you won't do any better than your two friends here."

Before anyone could respond, the sphere field that Yuma and Kotori had been in since before the start of the duel began to fade and drop to the ground. In seconds the field disappeared completely to reveal a fully clothed Yuma and Kotori. Yuma was once again wearing the Emperor's Key around his neck. Kaito groaned, causing Yuma and Kotori to notice both him and Droite on the ground. Yuma quickly kneeled down to see if Kaito was okay while Kotori checked on Droite.

"Kaito! Are you okay?" Yuma asked.

"…Yuma…. Be careful." Kaito told him. "The leader if the Death Queens… is very powerful."

"So, the great Yuma Tsukumo finally makes an appearance." Alnia spoke. "I should've just taken care of you myself from the beginning."

Yuma stood up and glared at Alnia and Mitaka. "You Death Queens have gone too far! Not only have you gone after and hurt my friends, you tried to hurt Kotori and get into my pants! There's no way I'm letting that go!"

"If you've got a problem, you're welcome to take it up with me." Alnia dared. "I'll be happy to pound you into the ground like I did with your two friends."

Suddenly a ball of blue light shot out of the gem of the Emperor's Key. The light grew and pulled in the Number cards from Kotori, Kaito, Vector and Alit's decks. Within a few moments, the light faded to reveal Astral. The energy being was no longer pulsing red and was glaring at Alnia and Mitaka with his arms crossed.

"Yuma will not be facing you alone, Death Queens!" Astral declared. "You have proven yourselves to be too great a threat to Yuma's world and mine! Therefore I have come to help deal with you myself!"

"Astral." Yuma spoke as a smile came to his face.

"Aw dammit!" Alnia cursed. "Great, Mitaka! Looks like this half-baked scheme of yours has only served to piss off Astral World's envoy!"

"I know you have been trying to steal the Numeron Code from me through Yuma." Astral told Alnia. "For what purpose do you want the code? Are you trying to revive Don Thousand?"

At this, Alnia burst out laughing. "Are you kidding? I wouldn't waste an ounce of spit to bring back that loser! The one we speak to revive is a demon god of shadows who can plunge this entire world into eternal darkness!"

"Astral and I won't let that happen!" Yuma declared. "So if you want a fight, bring it on!"

"…Not just yet, I think." Alnia decided. "I know a little something about what the two of you are capable of when you join forces. I'm still pretty confident I can beat you two to a pulp, but I need a better look at what you can do first. So let's do this. There's a big tournament happening in this city here in a few days, right?"

"She's right. The Millennium Tournament." Alit recalled. "It's this big event that's held every few years in honor of the great Yugi Muto, and this time it's being held in Heartland."

"…Yes, a tournament in honor of that wretched pharaoh." Alnia spoke as her hands balled into fists at her sides. "We'll use that tournament as the stage for our final battle. Sound good?"

"Sounds okay to me, I guess." Yuma agreed.

"Very well." Astral agreed. "Yuma and I shall face you in this tournament."

"We'll see you there then." Alnia replied. "Let's go, Mitaka."

Mitaka nodded, and suddenly a large vortex in the form of a red galaxy appeared in the end behind them. The two Barian women turned into balls of red energy and flew into the portal. As soon as they were though, the vortex vanished. Once the Death Queens were gone, Astral let out a pained groan and flickered for just a moment.

"Astral, are you okay?" Yuma asked.

"I am fine Yuma." Astral assured him. "I am still a bit weak from the curse Mitaka placed on us."

"Wait, she cursed you too?" a surprised Yuma asked.

"There is a connection between you and I since the two of us were once one being ages ago." Astral explained. "The Death Queens were trying to exploit that connection. Had Kotori been unable to act, I'm certain that both you and I would have perished. As it is though, I merely need some time to rest. I will be fine tomorrow."

"Okay then." Yuma nodded.

Astral closed his eyes and turned into light that flowed into the Emperor's Key. Meanwhile Kaito and Droite had managed to get back to their feet.

"Kaito, are you doing okay?" Yuma asked.

"I think so." Kaito replied. "Droite?"

"I'm fine." Droite assured him.

"You should get yourself checked out just in case." Kaito told her.

"Did the two of you duel that Death Queen who was just here with Mitaka?" Kotori asked.

"Yeah. Her name's Alnia." Kaito confirmed. "She's the leader of the Death Queens and very powerful. I'm not sure if you and Astral can handle her."

"Don't worry! Astral and I will be ready!" Yuma confidently declared.

Meanwhile, Cathy walked over to Kotori and pulled her away from the others. "Alit and Vector weren't very specific on what was going on her on the way over. Just what did you have to do to save Yuma?"

"Uh… well…" Kotori spoke as her face turned bright red. "I'd rather not say."

Cathy looked closely at Kotori for a few moments before her lips curved into a smirk. "I get it. Well, I don't know how that sort of thing would save Yuma's life. But it's about time the two of you got laid."

With that, Cathy walked back over Mizael. Kotori stood frozen on the spot, wondering if it would be just as easy for others to tell if she and Yuma had finally consummated their relationship.

It was the beginning of another day at Heartland Academy as seventeen-year-old Ryoga "Shark" Kamishiro walked into the school. A tired scowl was on the water duelist's face. His trip to Neo Domino had not been very relaxing, and his plane had arrived late that morning, barely giving him enough time to get home and change into his uniform. As Shark turned a corner, he saw Alit leaning against the wall.

"Hi Nasch." Alit greeted. "How'd meeting Hikari's parents go?"

"Could've gone worse, I guess." Shark answered. "They both seemed to like me. Of course one afternoon Hikari's dad gave Dubre and me a tour of the power plant where he works. One of the things he showed us was this machine that shot this huge beam of light into some tubes that go under water. It's supposed to supply Satellite Island with power or something. Anyway, Dr. Fudo made it pretty clear to the two of us that someone could throw a dead body into that beam and have it vaporized without it leaving a trace."

"…Oh." Alit replied, realizing what had been implied on the tour Shark had been on. "He did seem to like you though, right?"

"I think so." Shark answered. "So, anything happen here while I was out of town?"

"The Death Queens tried to make another move on Yuma." Alit replied. "I'll explain more to you over lunch. The good thing though is Astral is back to help out."

"Astral's back?" Shark responded, suddenly perking up a little. "Maybe I'll have quick word with him before class. Where's Yuma?"

"He's in that hall closet over there." Alit answered as he pointed to a nearby door.

Shark shrugged and went over to the door. He figured Yuma was in the closet getting something one of the teachers asked him for.

Meanwhile, Alit's eyes widened as he recalled the reason why Yuma had gone into the closet. "Oh crap! Nasch, wait!"

What Shark saw next when he opened the closet door completely shocked him. Yuma was in the closet all right, and he had Kotori pinned up against the wall. Kotori had her legs wrapped tightly around Yuma's waist and her shirt was pulled up just enough to show her bare breasts. Yuma was busy pounding his hips into the green-haired girl as she moaned and dug her fingers into his back.

In moments Yuma and Kotori hit their climax at the same moment. As they came down, they smiled and pressed their foreheads against each other. After a moment though they both turned their heads and saw Shark standing in the doorway of the closet. His jaw was hanging open and his left eye was twitching. Yuma and Kotori completely froze and their faces turned bright red.

"Uh… sorry." Shark finally managed to say after a moment. "I'll… catch up with you guys later." He then closed the door, but then opened it back up after thinking of something else he wanted to say. "For the record, this makes us even for that time you guys more or less walked in on me and Hikari."

Shark then tightly shut the door. He looked and saw that Alit was long gone. There was still a little time before classes were due to start, so Shark decided to go find Alit and pay him back for what just happened.

Mitaka nervously entered the throne room of the tomb-like pocket dimension she and the other Death Queens used as a base. Alnia was sitting atop her throne with her eyes closed. Mitaka looked and saw Anitak silently standing in the chamber.

"Hi Ani." Mitaka greeted as she walked over. "So, are you feeling better after your little incident with Alit?"

"I'm fine." Anitak answered. "Before you ask, Alnia seems to be in a better mood than yesterday."

"Good. I don't think I could take another thrashing from her." Mitaka replied.

"You just might get one if you're not careful, Mitaka." Alnia spoke, causing the two of them to flinch. Alnia opened her eyes and stood from her throne. "Well, you two have done a bang-up job trying to get us the damn Numeron Code. Anitak, your stupid plan did nothing, and Mitaka, you only made things a little worse by ticking off the envoy and having him return to Earth."

"Yeah. Again, sorry 'bout that." Mitaka responded.

Alnia sighed. "On the other hand, having Tsukumo and the envoy in the same place may make things easier for us in the long run. But it's clear we need to stop screwing around! I'm taking the lead on this. You two better do exactly as I say and not screw up."

"We will not fail you this time, Alnia." Anitak assured her.

"I know I certainly won't." Mitaka replied.

"Good. Then we've got a tournament to get ready for." Alnia told them. "And when we win, the human world will finally get what's coming to it."

HEARTLAND WITCH-END

Well, we've now come to the end of the second story in this little trilogy. It actually ended a little bit differently than I had originally planned. Before I was going to have Anitak return and have a tag duel between the teams of Kaito and Droite and Anitak and Mitaka, but I felt like that duel would've been a little too big. So instead I decided to use this last chapter to preview the main villain of the next story, Alnia. By the way, I think I forgot to mention before that the names of the Death Queens are derived from the names of the stars that make up Orion's Belt, sort of like how the names of the Barian Emperors were based on the stars of the Big Dipper. Anyway, I hope everyone reading enjoyed this little story of mine. This story was probably one of my weirder ideas, but I really enjoyed working for it. While this story may be over though, the battle with Barian Death Queens is far from done.

Stay tuned for the next installment of the Devil Numbers Trilogy: The Millennium Tournament

Until then, please review and let me know what you think.
