Trudge was driving Leo and Luna to the monkey control unit. Leo was looking at the rooftops and saw dozens of crows lining the rooftops staring down at them, and it was putting him on edge. Luna put her hand on his shoulder to try and get his attention, but scared him and caused him to yell out. "Don't scare me like that Luna," Leo said as he tried to slow his heart rate. "You scare me when you scream like that," Luna responded. "Sorry, it's just these freaky birds have me on edge," Leo admitted. "You shouldn't have come with me Leo," Luna said, worried about her brother's safety.

"Don't worry I'll be fine. I'm not gonna let some crazy birds scare me away. I'm here for you, and I'm not going anywhere," Leo said. Suddenly the spirit of Luna's Kuribon appeared in front of Luna and started jumping around frantically. "Something bad is happening in the spirit world isn't it?" Luna asked. "Who are you talking to back there?" Trudge asked. Suddenly Luna was enveloped in a bright light, and a beam of light shot into the sky. Alex and Yusei noticed and stopped to get a better look. "That's coming from the direction Luna went," Yusei said. "I have a bad feeling about this," Alex said to himself, pretty sure he knew what was happening.

Back in the truck, the light was so intense, it caused Trudge to lose control and he ran into a scrap heap. "Are you kids alright?" Trudge asked. "Yeah, I think I'm okay. What about you Luna?" Leo asked. He waited for a moment but didn't get any kind of answer. He looked towards her, but the only thing he saw was an empty seat. "She's gone!" he exclaimed. "What?! But how?!" Trudge asked in confusion. "That light came out of nowhere, and when it faded, she disappeared," Leo told him. "We've gotta find her, she could get hurt out here all by herself," Trudge said as he got out of the vehicle to look for her.

He and Leo walked around calling her name in an attempt to track her down. While Leo was walking, he came across the control unit. "Well, now we know where the control unit is. Now if we could just find Luna," Leo said aloud. "Devack, where are you!?" Leo called out. "I've been waiting for you Signer," Devack called out as purple flames sprung up around Leo, creating the monkey geoglyph.

Akiza noticed the symbol floating in the sky and pointed it out to Mina. "It looks like Luna's duel is about to begin," Akiza said. Jack had stopped his duel runner and was staring in the direction of the geoglyph. "Looks like the final round has begun," he said to himself. Back at the duel field, Leo had just come to the realization that he was about to duel Devack.

"Who are you? What's going on here? You're not a Signer, what are you doing here?" Devack asked. "I'm here to duel you. That is unless you're afraid to take me on," Leo challenged. Trudge ran to the top of a nearby hill and saw Leo in the middle of the barrier. "Leo!" he called out. "Is this some kind of joke? Where's the little girl? Why isn't she here? I told her to come," Devack spat out. "I won't let you hurt my sister, so you're gonna have to duel me instead. I may not be a Signer, but that doesn't mean I can't duel, so bring it on!" Leo shouted as he activated his duel disk. "I applaud your enthusiasm boy, I truly do, but you lack the power to defeat me," Devack taunted as he activated his duel disk.

Both: "Let's Duel!"

Leo: 4000 LP

Devack: 4000 LP

"Leo, get out of there, don't be a fool!" Trudge shouted. Just then, Alex and Yusei showed up on their duel runners. "What are you two doing here?" Trudge asked. "I turned around when I saw that pillar of light. What's going on?" Yusei asked. "Well first, Luna disappeared to who knows where," Trudge said. "She must've gone to the spirit world for some reason," Alex said. "There's no such thing as the spirit world," Trudge said. "After everything you've seen, you really think that?" Alex asked. "We can talk about this later, right now we've gotta stop this duel," Yusei said before turning to Devack.

"Hey Devack, that kid's not a Signer! You can't duel him!" Yusei shouted. "I already am. And once a shadow duel begins, it cannot be stopped until somebody wins," Devack responded. "Then let's get going. It's my move! I summon Morphtronic Magnen in defense mode. I place one card face-down and end my turn," Leo said. My set card is Morphtransition, so if he attacks, I can negate his attack. Then if I can summon another Magnen on my next turn, I'll be able to stop him from attacking, he thought to himself. "Leo, you've gotta stop this! You need to find a way out of this!" Yusei shouted. "No way Yusei! If I can beat Devack then Luna won't have to face him!" Leo shouted.

"Leo is stronger than you give him credit for Yusei," Alex said. "But is he strong enough to beat a Dark Signer?" Yusei asked. "All we can do right now is hope Leo has what it takes to win," Trudge said. "You guys stay here and make sure Leo pulls through, I'm gonna see what I can do to help Luna in the spirit world," Alex said before he walked back to his duel runner. "But how are you going to get to the spirit world?" Yusei asked. "Just let me worry about that," Alex said as he got on his duel runner and drove off. As he was driving, his duel runner started to be cloaked in shadows before he drove into the shadow of a building and disappeared. "Good luck Alex," Yusei said to himself.

Meanwhile, Luna was coming to in the spirit world. She raised her head up and saw she was in some kind of forest. "Looks like I made it," she said as she sat up. She was then greeted by a familiar spirit. "Kuribon it's you," Luna said as her favorite monster appeared. Luna turned her head to the side and saw a large mountain in the distance. "That's the mountain where Ancient Fairy Dragon was sealed away," she said. Back in the real world, Leo and Devack's duel was proceeding. "It's my turn, I draw. And I summon Magician Ape in attack mode," Devack said.

Level 3/DARK/Beast

ATK 800/DEF 1200

"I now activate my monster's special effect. By discarding one card, I can take control of one of your monsters, but I cannot change the battle mode of that monster, so I discard one card and take your Morphtronic Magnen," Devack said as his monster launched a stream of blue lightning from his staff, dragging Magnen to Devack's field. "And with that out of the way, Magician Ape attacks you directly!" Devack shouted as his monster shot a bolt of purple electricity at Leo, causing him to cry out in pain. "Leo!" Trudge shouted. "Hang in there!" Yusei added.

Leo: 3200 LP

In the spirit world, Luna could hear her brother screaming. "That sounded like Leo just now. You don't think he's dueling do you Kuribon?" she asked. Back at the duel, Leo had fallen to his knees. Well, that hurt. This duel is as intense as when Luna and I dueled Nightshroud, Leo thought to himself. "Don't worry, I'll try to send you to the Netherworld with as little pain as possible. That is the only mercy I can offer you," Devack said. I won't let you hurt Luna! Leo thought to himself. He shakily got to his feet and breathed deeply for a minute before continuing the duel. "It's Leo's turn, but I'm worried, he doesn't look so good," Yusei commented.

"He's a tough kid. He can handle whatever Devack throws his way," Trudge said. "I know you're right Trudge," Yusei said, remembering when he took on Nightshroud. "Your friends up there seem to think you can handle more punishment. Care to test that theory?" Devack asked. "You bet I do! I draw!" Leo shouted. Magnen Bar. This isn't much help to me. Wait! If I summon it, I bet Devack will try to take it using his Magician Ape's effect, and if he does, Leo thought to himself. "I play Morphtronic Magnen Bar in defense mode," Leo said as he summoned his monster.

Level 1/EARTH/Thunder

ATK&DEF 100

"I'll end my turn with a face-down," Leo said. "It looks like you're scraping the bottom of the barrel," Devack said. We'll see about that Devack. I won't let you hurt Luna, Leo thought to himself. Back in the spirit world, Luna was running through the forest. I can't believe I'm back in the spirit world. Now that I'm here, I have to keep my promise and save the Ancient Fairy Dragon! she thought to herself.

She remembered what the Ancient Fairy Dragon had told her, and that she had to find Regulus. Okay, so I've gotta find Regulus, rescue Ancient Fairy Dragon, take her back to the real world to help Leo, defeat the Dark Signers, and save the planet. Easy, Luna thought to herself. As Luna was running, she saw a town in the distance. She arrived in the city and it seemed to be abandoned. "It doesn't look like anyone is here," Luna said. She looked ahead and saw numerous duel spirits down the road. "Hi, I'm Luna, can you help us?" she asked as she approached them.

They all ran away when she got close. "Wait, we're not going to hurt you!" Luna shouted as she ran to catch up to them. She turned down one of the streets and saw the spirits running away. "What are they afraid of?" Luna asked. Luna saw one of them around the corner of one of the buildings. The spirit realized it had been spotted and ran away. "Wait! Don't run away!" Luna shouted as she gave chase. If we don't catch those kids, we'll never find Regulus, Luna thought to herself as she stopped to catch her breath. Luna spotted a nearby bench and stopped to rest on it. After sitting down for a minute, she steadied her breathing and tried to figure things out.

"I just don't get why they're scared of us," she said to Kuribon. She lifted her head to see numerous spirits watching them before they ran away. Kuribon got Luna's attention and directed her attention to a nearby flight of steps. "What is it Kuribon?" she asked as she walked over. When she reached the stairs, she saw a ball bouncing, but what really grabbed her attention was that the ball was bouncing up the stairs. She caught the ball as it bounced towards her. "Okay that's strange, since when do balls bounce up stairs?" she asked aloud. She then heard a rustling sound and turned her head to the side and saw leaves rising up off the ground and reattaching themselves to a tree.

"It's like everything is happening in reverse here. If we don't find out what's causing it, I might end up in diapers again," Luna said. Kuribon made another sound, talking to Luna. "You think it's that staff? They're all over town," she said. A strong breeze then blew through the town. "Where's that wind coming from?" she asked. "The collectors are coming!" someone shouted. "Who are the collectors?" Luna asked. "They capture all the duel spirits!" one of the other spirits shouted. "Hurry, this way!" one of them shouted, the other spirits following close behind. Suddenly, a purple mist seeped out of one of the streets near Luna, who dropped the ball she was holding in fear.

"I don't know what that is, but let's not wait around to find out!" she said as she started running away. The mist faded away and revealed a troop of monkeys wielding staffs like the ones littered around town. "I don't want anyone messing around like last time," one of them said. "Whatever you say boss," one of the other monkeys replied. "I wanna find some spirits and turn 'em into stone!" one of them shouted. "Keep searching!" the head monkey ordered. Luna had hidden away in one of the side alleys with Kuribon. "No wonder everyone's hiding," she said quietly.

Suddenly Luna's deck began to glow. She pulled it out and held it close to her, trying to calm her duel spirits. A group of duel spirits came running down the street, followed closely by the monkey soldiers, one of whom turned down the street Luna was on and found her. Luna screamed out before Kuribon, Sunny Pixie, and her Sunlight Unicorn manifested themselves and ran away.

"Wait, stop!" Luna shouted. The monkeys chased after her spirits. "Oh they'll stop alright," one of them said. The monkeys pointed their staffs at Luna's spirits and launched beams of purple energy at them, locking them into large stone tablets that looked like their duel cards. Having petrified them, the monkeys turned their attention back to Luna, who proceeded to run for all she was worth.

She kept running until she wound up in a dead end. "Oh no," she said to herself as she turned around. She could see that the soldiers were approaching the alley she was in. Suddenly, one of the pavement stones lifted up, revealing a spirit Luna was familiar with. "It's you!" she exclaimed. "This way lady Luna," the spirit said. Luna dove into the hole with the spirit and the stone dropped just before the soldiers arrived at the alley. "Huh, didn't she run down this alley?" one of them asked. "She's got to be around here somewhere, fan out and find her!" one of the other monkeys ordered.

Hey everyone. Well, the duel between Leo and Devack has started. And who is this familiar spirit? Stay tuned to find out.
