Chapter 50: The Giant

Third Person POV

Yusei drove his way to the Giant Tower to face Kalin closely followed by Crow, Leo, Luna, and Trudge.

Yusei then thought, 'Era, I sure hope you're alright. Just… don't die on me. Especially after leaving me like you did.'

"I'm worried about this duel. Especially since Yusei and this guy seemed close," Luna stated.

"It'll be fine, Luna," Leo reassured his twin.

Yusei looked and noticed Kalin waiting at the base of the tower. Kalin revved the engine of his duel runner and sped head on in front of Yusei. Both Yusei and Kalin swerved their duel runners to one side, avoiding the collision.

Kalin gave a maniacal grin and said, "It's time for us to settle the scores, through the last Duel of the Enforcers. The one that never was completed back then.

"Last duel…" Yusei muttered before reflecting back on the incident when they were the Enforcers.

Kalin laughed again and raised a finger. "Let's get things started." Crow and the others arrived at a spot a few blocks away from the tower, giving them a decent view of the turbo duel about to take place. Kalin chucked off his cape, revealing his dark mark, and said, "This will be the last duel." His mark glowed and the purple flames erupted and shaped the Giant geoglyph.

. . .

Era turned as she saw the mark appear in the sky. 'Be careful, Yusei,' she thought before a shot from Equette shot her back.

"Worried for the precious Signer?" Equette asked.

"Of course," Era answered and shot an attack back.

. . .

"I can see the events of this duel. I will kick you into the middle of the inferno of vengeance from the depths of death, with the power of my Earthbound Immortal!" Kalin called.

'Kali was never like this. He had cared for his friends. He kept me from falling off a building, saying he would never leave his friends. I'm going to save you in this duel Kalin,' Yusei thought.

Both duelists lined up to begin the shadow turbo duel. They activated Speed World and took off.

"Who passes the corner up ahead first goes first in the duel," Kalin stated. As such, they raced. Kalin then noticed something, 'So Yusei's powered-up his runner since our last duel. Well, he won't be going first!' Kalin rammed his duel runner into Yusei, knocking the Signer into the fiery wall.

Kalin passed the corner and won the race to go first. "I get to go first. I summon Infernity Necromancer (Attack 0/Defense 2000) in defense mode," he declared.

'An Infernity monster. Is Kalin going to try his handless combo again?' Yusei thought.

"I set one face down and end my turn," Kalin finished. "Bring it on, Yusei!" Yusei drew his card and paused for a moment, remembering another instance while they were the Enforcers. "Hurry up, traitor!"

"Fine," Yusei responded. "I summon Max Warrior (Attack 1800/ Defense 800) in attack mode. Max Warrior, attack Infernity Necromancer!" He then thought, 'Hopefully, I can get the real Kalin back in this duel.'

"Oh, Yusei!" Kalin called. "The defense of my monster is great than the attack of yours."

"Not with Max Warrior's ability. When it attacks, it gains 400 attack points (Max warrior: Attack 2200)," Yusei retorted. Infernity Necromancer was destroyed. "But due to its other effect, Max Warrior's attack, defense, and level will be halved until my next turn (Max Warrior: Attack 900/ Defense 400/ Level 2)." Yusei then thought back on how he and Kalin had always stayed side by side, 'Until that night, that is.'

-Flashback-

Yusei and Kalin looked as they noticed captain of Sector Security had arrived in Satellite on a duel runner.

"Sector Security has deployed a lot of duel runners," Kalin told Yusei.

"Show those duel gangs the power the duel runner holds," the captain told his troops. "Use their dueling to judge them." Sector Security then began to pursue any of the duel gangs. Kalin only smirked. The captain captured a member of another duel gang after that.

. . .

The next day, Kalin surprised Yusei by saying, "We need to crush Sector Security."

"What?!" Yusei responded.

"I have finally found the Enforcers' final enemy. Only by defeating Sector Security will our true conquest of Satellite be complete," Kalin replied. "Go get Crow and Jack for me. Together we'll reunite and crush Security."

"Kalin, this is suicide," Yusei retorted.

"Are you chickening out?" Kalin asked.

"We can't do this, Kalin. If you actually want to go through with this, you'll have to do this on your own," Yusei replied and left thinking, 'Kalin won't take on Sector Security if he's all by himself.'

Later that night, rain began to pour down. Yusei, Jack, and Crow went in search of Kalin after hearing he was being chased by Security. They found Sector Security finding their friend in an abandoned building and one told him, "Quit resisting and come out quietly."

Two officers were about to go inside until Jack and Crow managed to get inside first, completely surprising the two officers. Yusei managed to get inside the building using the stairs behind it. They were quick to meet up with Kalin in a room.

"The Enforcers are together again!" Kalin exclaimed.

"What's going on?" Jack asked him.

"Oh yeah! Our last duel will be against Sector Security," Kalin responded too happy to listen to them.

-Flashback Ended-

'We were there to help him. But I made the wrong decision back then. That's why I've decided to save him today, just like he saved me,' Yusei thought. He finished his turn with two face downs.

Kalin drew his card to begin his turn. "I set a face down and activate Limit Impulse! By sending two cards from my hand to the graveyard, I can special summon two Soul Tokens (Attack 0/ Defense 0)," he declared. "Next I tribute them to summon Dark Tuner Nightmare Hand (Attack 0/ Defense 0) in attack mode."

'Kalin's definitely going to use his handless combo technique,' Yusei thought.

"Now with the effect of Nightmare Hand, I can special summon a level two monster from my hand. So I summon Infernity Dwarf (Attack 800/ Defense 500) in attack mode. And now with my two monsters, I will dark synchro summon! Come forth from the darkness Hundred-Eyes Dragon (Attack 3000/ Defense 2500)!" Kalin called. "My handless combo is complete! Hundred-Eyes Dragon, attack Max Warrior! Say, Yusei, I wonder what'll happen to your poor angel with Equette's little plan." Yusei looked at him worried as his monster was destroyed and his life points fell to 1900. "Have you found this pain superb?"

"I activate Revival Ticket! By destroying one card on my field, I can bring back each monster destroyed by battle and recover my life points equal to the battle damage," Yusei declared. "So I destroy my Limiter Break to revive Max Warrior and regain the life points I just lost." His monster returned to the field and his life points returned to their original 4000. "And due to the effect of Limiter Break, I can special summon Speed Warrior (Attack 900/ Defense 400) from my hand, deck, or graveyard."

Kalin was angry and asked, "What can you do before me Hundred-Eyes Dragon?"

Yusei drew his card. "What're you talking about Equette's plan?" he asked Kalin.

Kalin laughed. "Always worried for Era, aren't you? Well, if you must know, say, did you notice that new mark that appeared in the sky?" he asked. Yusei glared. "That was Equette's plan coming into play. You see, this dark fire saps away an angel's energy. Especially if they're dueling. And he made it so each time she lost life points, she lost some energy. For him, he just got stronger. It won't kill her. He was saving what was left of her for a real angel-demon battle."

Yusei grew worried with that information. 'Era, please… stay alive,' he thought. He then continued the duel, "I activate Card of Sacrifice! This allows me to draw two cards since the combined attack of all the monsters on my field are lower than yours. But during this turn, I can't summon a monster or switch battle positions."

"You're in a deadlock. It's pathetic," Kalin stated.

Yusei ignored him and drew his cards. "I set two face downs and end my turn," he finished.

Kalin drew his card. "I place a card face down and activate my Hundred-Eyes Dragon's effect, which means it gains the effect of any of my dark attributed monster in my graveyard. I choose the effect of Infernity Necromancer. This allows me to summon a level four or lower Infernity monster. Like my Infernity Archfiend."

"I activate Slip Summon! When you summon a monster, I can summon a level four or lower monster from my hand in defense mode. So I summon Ghost Gardna (Attack 0/Defense 1900)!"

"A typical futile resistance," Kalin stated. "I'll have the terror of my handless combo pierce you to the bone. Hundred-Eyes Dragon, attack Speed Warrior!"

"I activate the effect of Ghost Gardna to make it the new attack target," Yusei fought.

"I activate the effect of Hundred-Eyes Dragon. This allows me to take the effect of Infernity Dwarf in my graveyard. When my hand is empty, if a monster on my field attack a monster in defense position and it attack is greater than the monster's defense, I can deal battle damage equal to the difference," Kalin retorted. Yusei's life points fell to 2900 and the attack made him lose control of his runner for a moment. "Don't die on me here, Yusei! It's far from being enough. That doesn't come close to extinguishing my inferno of vengeance." Yusei remained determined and regained control of his runner. "Infernity Archfiend, attack…" Kalin stopped noticing his monster's effect had turned to 800. "What happened to its attack?"

"See, Ghost Gardna's got another effect. When it's destroyed, it decreases your monsters attack by 1000 until the end phase," Yusei informed. Kalin growled. "Now it's my turn!" He drew his card. "I summon Junk Synchron (Attack 1300/ Defense 500) in attack mode. Now I tune Speed Warrior with Junk Synchron to synchro summon! Fight, Junk Warrior (Attack 2300/ Defense 1300)!" His monster appeared ready to fight. "Next I activate Synchro Strike Unit! By equipping it to Junk Warrior, it gains 1000 attack points (Junk Warrior: Attack 3300). Now Max Warrior, attack Infernity Archfiend! And with its effect, it attack increases by 400 (Max Warrior: Attack 2200)."

"I activate Infernity Force! This destroys your Max Warrior since I have no cards in my hand," Kalin defended. "And then special summon a level four or lower Infernity monster from my graveyard. So I summon Infernity Necromancer (Attack 0/ Defense 2000)."

"Junk Warrior, attack Hundred-Eyes Dragon!" Yusei ordered. The attack hit and Kalin's dragon was destroyed as the Dark Signer's life points fell to 3700.

Kalin laughed. "Thanks to my dragon's effect, I can add one card from my deck to my hand. But you knew that, didn't you?" he asked Yusei.

"I set two face downs and end my turn," Yusei finished. And due to the effect of Synchro Striker Unit, Junk Warrior's attack decreases by 800 making it a total of 2500. He saw Kalin card and thought, 'It's Earthbound Immortal Ccapac Apu. I have to save Kalin.'

While watching the duel, Crow stated, "Yusei's trying to save Kalin, just like before." They looked at him and he began to explain everything.

-Flashback-

Sector Security had cornered Kalin's hideout with Kalin, Yusei, Jack, and Crow inside. Kalin's friends removed their duel disks from their wrists and put them on the table.

"What's going on?" Kalin asked. "Aren't we going to fight together?"

"Open your eyes, Kalin," Jack told him.

"We don't have a chance if we go up against Security head on," Crow added.

"You guys, get out of the building," Yusei told them.

"That won't satisfy me. We defeated Satellite and dominated it for the first time. Let's have our last duel," Kalin begged.

"We don't have the same views as you anymore," Jack told him.

"What?!" Kalin exclaimed disbelievingly.

"We're friends, Kalin, and we want to save you from Sector Security," Yusei told him.

"What did you say?" Kalin asked shocked.

Sector Security then began to attack the building. The four managed to escape the building, only to be pursued by the Sector Security. They got separated and Kalin found himself trapped at a dead end. An officer appeared and Kalin looked at him.

"I'll just have to fight by myself, then," Kalin stated. The duel began and as it went on, Kalin then jumped at the officer. The two began to struggle making the agent lose control of his runner.

Yusei managed to find Kalin and called, "Kalin, stop!" The runner hit the wall and both Kalin and the officer landed hard on the ground. Unlike the officer, Kalin remained conscious. Kalin grabbed a wooden stick and was about to beat the officer but Yusei grabbed his wrist. "Kalin, this needs to stop!"

The two began to fight with Kalin repeating, "We have to crush Sector Security." Crow and Jack found the two and all four hid inside another abandoned house.

Jack then said, "It's only a matter of time before we're found out."

"Jack, Crow, take care of Kalin," Yusei told them.

Yusei then stepped outside to Sector Security. "I'm the leader of the Enforcers and was the one who attacked the Sector Security Headquarters. Take me in and leave the others out of this," he told the officers.

The captain appeared and told the other officers, "Secure the leader." They came out with an arrested Kalin, shocking Yusei.

"No, you've got the wrong leader. I'm the one you want," Yusei tried.

The captain refused to listen and said, "Defiance against Sector Security is a first-class crime. You won't be seeing him again anytime soon." He laughed and touched Yusei's shoulder while Yusei glared at him.

Kalin looked at became furious. "You betrayed me?!" Kalin yelled as the officers dragged him into the wagon. "You traitor!"

"No, Kalin, I…" Yusei tried but Kalin was too angry and kept cutting him off before Yusei could explain.

"Kalin!" Yusei called as Sector Security took him away.

-Flashback Ended-

"Jack, Crow, and I tried to save you that day," Yusei told Kalin in the duel.

"No, you all betrayed me!" Kalin refused.

"Kalin, you've got it wrong," Crow told him. "Yusei tried to surrender in your place."

"Why didn't you fight with me until the end and bend to Sector Security's questioning? These actions only mean you sold me out," Kalin asked. "Do you know what fate awaits those who oppose Sector Security? They didn't even numb it when they put the marker on my face. And the guards kept abusing me."

"We tried to visit you. But we were never able to meet you," Crow explained. "We heard news that you had died."

"It wasn't that simple!" Kalin yelled. "I could have withstood countless brutality, but when the Securities took away my deck that was more precious to me than my life… After that, I went into a depression in which I refused to eat and left myself starve to death. On that night, a voice asked what my desire was. It told me to have this desire, I must become a Dark Signer. I told it I want vengeance and I died. By becoming a Dark Signer, I swore revenge on you and I'll make you go through the worst fears I had to endure. All through my Earthbound Immortal. Now it's my turn!" He drew his card. "I tribute my Infernity Necromancer and my Infernity Archfiend to summon my Earthbound Immortal Ccapac Apu (Attack 3000/ Defense 2500)!" The dark monster rose from the ground and stared right at Yusei. "Earthbound Immortal Ccapac Apu, attack Yusei directly!"

'I'm not going to run in fear anymore,' Yusei thought. 'And by sending his Earthbound Immortal to its doom, I'll face Kalin's fears.' Yusei then fought, "I activate my trap card, Baton of the Hero! During this turn, I can designate an opposing monster's attack target. So I switch the target to Junk Warrior!" The attack destroyed Yusei's monster and dropped his life points to 2400.

"So you managed to use a monster to shield yourself to evade your Earthbound Immortal, hm?" Kalin responded. "I activate Ccapac Apu's ability! This inflicts damage to you equal to your destroyed monster's attack points."

"I activate my face down, Burst Synchro Summon!" Yusei defended. "This reduces the battle damage to zero and allows me to summon a synchro monster with attack equal to the effect damage I would've taken, ignoring summoning conditions. So I summon Stardust Dragon (Attack 2500/ Defense 2000)!"

"I set a face down and end my turn," Kalin declared.

"It's my turn," Yusei called drawing a card.

"I activate the continuous trap, Brilliant Shrine Art! This lets me redirect any attacks to my Earthbound Immortal," Kalin declared.

"I activate the Speed Spell- Angel Baton! Since I have two or more speed counters, I can draw two cards and send one card from my hand to the graveyard. So I send Stardust Xiaolong to the graveyard and activate its ability. Since I have Stardust Dragon on my field, I can special summon Stardust Xiaolong (Attack 100/ Defense 100) to the field," Yusei declared. "I then end my turn with one face down." Kalin drew his card. "I activate my trap card, Superior Protector! By equipping it to Stardust Dragon, I can nullify any battle damage to him except through battles involving the equipped monster."

"So you're containing direct attacks, too. But I'll crush that Stardust Dragon. Earthbound Immortal Ccapac Apu, attack Stardust Dragon!" Kalin ordered.

"I activate the effect of Superior Protector! By sending it to the graveyard, I can negate Stardust Dragon's destruction by battle," Yusei defended.

"You still take damage. And to make it worse, I activate Wicked Trample, which doubles the damage you've received except those caused by direct attacks," Kalin retorted.

Yusei was surprised as his life points fell to 1400. The thrust of the attack caused Kalin to lose control of his runner for a moment. Yusei rode up and tried to help him, making Kalin remember the day he saved Yusei from falling off a building.

"I was wrong to think I could save you by sacrificing myself. Only the unity of companions can save a companion," Yusei told Kalin. Suddenly all their marks began to glow bright. "Both Crow and Jack share the same concerns. Plus, our new friends are giving us their support. This isn't a battle to defeat you, Kalin. It's to save you from the Dark Signers."

"What's it matter now?" Kalin asked.

Kalin lost control of his runner again and Yusei called, "Kalin!" His mark glowed brighter before all the marks, including the fifth Signer's, appeared on Yusei's back, creating the complete mark of the Crimson Dragon.

"Our wishes will cluster together and be completed," Yusei said. He saw a light from his deck and drew his card. 'This car will lead me to a miracle and save Kalin,' he thought. "I summon Majestic Dragon (Attack 0/ Defense 0). And now I tune Majestic Dragon with Stardust Dragon and Stardust Xiaolong to synchro summon. Rise up, Majestic Star Dragon (Attack 3800/ Defense 3000)!"

"Do it, Yusei," Kalin told him.

Yusei nodded. "I activate Majestic Star Dragon's effect. It can negate the effect of your Immortal and gain the effect for itself until the end phase," he declared. "Now, Majestic Star Dragon, attack Earthbound Immortal Ccapac Apu! End this!" The Immortal was destroyed and Majestic Star Dragon was able to use its effect to reduce Kalin's life points to zero.

Yusei came to Kalin's side as he stopped his runner. "I'm going to save you this time," Yusei told him.

Kalin's eyes turned to normal as he said, "When I became a Dark Signer, I asked for one more thing: that I wanted to play the last duel of the Enforcers, the one that never came true back then."

"Kalin…" Yusei muttered.

The geoglyph disappeared and Kalin said, "I wasn't able to stay mad at you. That isn't enough to satisfy me." Then then turned to dust and faded away.

"Kalin, for you, I will defeat the Dark Signers," Yusei stated. A tear rolled down his face. "Kalin…"

Yusei put his Stardust Dragon into the control unit and the Giant Tower sunk into the ground. He turned and saw Leo, Luna, Crow, and Trudge at a bridge who were greeting him. He rejoined them and Crow pointed up as a light appeared and half the citizens of the Satellite were returned.

"The people who were sucked up by Earthbound Immortal Ccapac Apu must've come back," Crow concluded.

"Yeah," Leo agreed while Luna nodded.

"Nice win, Yusei," Crow congratulated.

"It's too early to celebrate. In order to close to the doors to the Underworld, two more towers have to be sealed," Yusei responded. "There is still three more Dark Signers out there."

"And that demon," Trudge stated. "Where was Era going to beat that thing again?"

"Above the Original Ener-D Reactor," Yusei answered. Trudge suddenly tensed and Yusei noticed it. "Everyone, get back from Trudge."
