Hi there all you people out there. I'm here for my first mystery/romance fiction. In this story, some of the characters from Yu-Gi-Oh! (classic), GX and 5D's come together to solve a mystery happening at Duel Academy Island. This is an alternate version of the GX story line, it's also my own twist. I also have and OC for this story, and I based him a little bit on myself, and gave him the name Justin Desoto. My middle name is his first name. So, in this story Justin got the job at Duel Academy as Campus Detective. And his first case; To find a werewolf on the campus. So, with that part said, let's get on with the story.

Chapter 1: The Mystery Starts!

It was a dark and blustery night at Duel Academy island. But not blustery enough for this young man we see on the roof of the Slifer Red dorm. His messy brown hair blowing in the breeze, his green eyes looking over the ocean. He was wearing a tan jacket that had a grey hood, and he was wearing blue denim jeans. He also had brown Sketchers on his feet. This young man was Justin Desoto. He is a 19 year old young man who recently got a job at the academy, as Campus Detective, and this is his first night on the job.

"Man. What an uneventful night." he said as he was feeling bored. "I was hoping to get a mystery to solve, but lately there haven't been any crooks about."

Just then, there were some weird sounds going on. These were different from the usual ones. It was the sound of a scratch, and an animal roaring. Justin was alarmed by that kind of sound. *GASP* "That sounded like it was coming from the docks!" he exclaimed. "I'd better get over there!" So he climbed down a ladder, and jumped of the roof of the cafeteria to the ground. Then he started to run towards the docks, and he was curious to that sound.

Now at the docks we see a shadow of some sort of creature, and as it was scratching at the wall of the storage house, it heard footsteps coming closer. So it bolted out of there. Justin was panting as he ran up to the site. By the time he got there, he noticed something out of order on the place of where the unknown creature was.

*GASP* "What the shell happened here?" Justin wondered. He noticed some pieces of evidence. It was really bizarre to him. He approached the site, and saw 3 count'em 3 long scratches, a chunk of Coarse Grey fur, and a trail of Paw Prints covered in mud. Those were not normally there in the first place.

"Claw marks?" he asked himself again. "What would be strong enough to leave this here?" he wondered. He got out his camera, and took pictures of the evidence.

"I gotta warn Sheppard about this." Justin said to himself. "And, I gotta call Yugi Moto to get his help."

The next morning, we see Justin contemplating about the evidence he saw last night as he was walking to Chancellor Shepard's office. He was puzzling and puzzling, and also he was thinking of it too.

"I wonder what creature did that mark I saw last night." he thought. Then he said to himself out loud, "For some reason I'm drawing a blank."

The double doors opened revealing the chancellor's office. Sheppard was at his desk as always. Justin walked up and said to him, "Chancellor Shepard, I must speak with you!"

"What is it, Justin?" Sheppard asked as he was wanting to know.

"I found something strange last night." he informed the middle aged man.

"Such as?" Sheppard asked again. Justin showed the pictures of the scene to him.

"Claw marks, a chunk of fur and a trail of paw prints." Justin stated. "I think that there's some sort of creature on the loose."

The chancellor gasped as he heard this shocking turn of events. "Oh my, this is not good." Sheppard said. "We need backup for this job!"

"My thoughts exactly." Justin agreed to that statement. "Maybe Yugi Moto knows something about this mess." Sheppard suddenly had an idea.

"That's the solution!" Sheppard exclaimed. "If the king of games was here, he could help us with this situation."

"Okay, I'll call him immediately and see what he can do." the detective stated.

"Good plan, Justin!" Sheppard said to him. "Contact him at once!"


So Justin got out a cell phone and used the number that Shepard had given him. It was definitely the phone number for Yugi's house.

"Hello...Moto Residence." Yugi said as he answered the phone. "Who shall I say is calling?" he asked.

"This is Justin Desoto." he replied. "I'm calling for Yugi Moto. Is he there?" he asked back to Yugi.

"This is him speaking." Yugi replied.

"Oh good." Justin said as he was gonna tell him what was going on. "Get your friends over here right now! I need your help with something!"

"Okay, what's the situation?" asked Yugi.

"There is something supernatural happening here." Justin replied.

"WHAT!?" exclaimed Yugi as he was stunned about this whole thing. "What sort of supernatural thing?" he asked.

"I'll brief you and the others on the situation if you can get over here." Justin stated.

"Where are you, Justin?"

"I'm at Duel Academy Island." Justin replied.

"We're on our way, Justin!" Yugi said as he hung up.

"Okay, see ya, dude." Justin hung up on his end. Now, Yugi's ancestor, Pharaoh Atem came into the room as a ghost.

"Yugi what's going on?" Atem asked to his reincarnation.

"Well, there's something supernatural going on at Duel Academy."

"That's the school Kaiba founded." Atem said as he had heard about it from Tristan Taylor. He read an article about it in the newspaper. "I wonder what is going on."

"I don't know, but let's get the other's and head on over there." Yugi said boldly as he packed his things and went to inform the others.


A few hours later...

We now see a boat docking at by Duel Academy Island, in front of the crime scene. And out of the boat came Yugi along with Joey Wheeler, Tristan, Tea Gardner, Serenity Wheeler, Mako Tsunami, Duke Devlin, and Rebecca Hawkins. One by one they all came out and saw our young detective standing there waiting for them.

"Ah, hello there." he greeted. "I'm Justin Desoto, campus detective here at Duel Academy. I see your got my call."

"Yep. Sure did." Yugi replied. "So, what's the trouble?" he asked.

"Follow me, and I'll show you." Justin replied as he showed them the scene of the crime. "This is it." he said as they all looked.

"Whoa! What happened here?" Tristan asked.

"There's something supernatural going on around here." Justin said. "I spotted this last night, I even got some photos of the incident."

"Really?" Rebecca asked. "Well, this is quite a finding that needs examination, at once." she said as the child prodigy she was. She had graduated from collage a few months ago.

"Indeed. Which is why I need your help with this case." Justin agreed.

"Okay, but what could have made this scene?" Tea asked.

"Well, the evidence so far is 3 long scratches, a chunk of coarse gray fur, and a trail of paw prints." Justin stated. He got most of his lingo from reading Sherlock Holmes one too many times.

"Whoa!" Serenity was stunned by the sound of this whole thing.

"So, Justin. What happened to da thing dat did dis?" Joey said with his Brooklyn New York dialect.

"Well, it might have run off into the woods or the far side of the island."

*GASP!* Yugi gasped about this. He had no idea that the beast that made the mark and left the other evidence.

"Jumping Jellyfish!" Mako said as he made his own freaking out phrase. Being that he was a fisherman, he would need a phrase like that. "I think I know what creature made those paw prints." he sated as everyone looked at him.

"Really Mako?" asked Duke. "What was it?"

"It looks like a Werewolf." Mako said as everyone gasped collectively.

"What!?" Justin said with a shocked look on his face. "A WEREWOLF!?"

"Mako, are you saying there's a demonic creature on the loose, and where people can see it?!" asked Joey.

"Yep." Mako said back to him. "That's it."

"Well, we're gonna have to try and bait it out into the open." Justin said as he thought of something. "But how?" he wondered as he paced.


Just then, we see a young man in a gray suit walking over to the detective's position. He had silver hair, icy blue eyes and was also a Pro-Duelist. This was Aster Phoenix. He had a Destiny HERO monster deck, and he still had no evidence about his father...Yet.

"Hey, what's going on here?" Aster asked as Justin turned around and saw him. The others were surprised to see someone like Aster being at this school.

"ASTER PHOENIX!?" was the wondering of the gang. "What are you doing here?" asked Yugi.

"Well, I've been looking for evidence about my dad's disappearance." the silver haired boy replied.

"I never realized you both knew each other." said Justin as he was surprised.

"I met him when I saw Pegasus at a conference a long time ago." Aster stated. "Jaden's gonna freak when he sees you, dude."

"Really?" Yugi wondered.

"Yeah." Aster replied.

"He sure is." Justin added.

"Well, what are we waiting for?" Joey asked. "Lets' meet this kid, and see what he's got."

"Okay, follow moi." Justin said as he said the French word for 'me'. The lot of them made they're way to the Slifer Red dormitory and Jaden was shocked to see his idol at the school because there is an emergency.

"WHAAAAAAH!" Jaden said as he screamed with glee. "YUGI MOTO! HERE? It's an honor to have you at the Slifer dorm" he said as he shook Yugi's hand.

"Uh...The honors all mine, Jaden. I think I gave you that Winged Kuriboh card when you were on your way to the entrance exams." Yugi stated as he brought that subject up.

"That was you?" the boy in red asked. "But, you looked taller and you had a deeper voice."

"OH, you must mean my ancestor, Pharaoh Atem of Egypt." Yugi said as he mentioned the name of his past life.

"Your...Ancestor?" Jaden did not know that it was Yugi's other self that gave him the card in question. "Oh, right. I forgot about that."

"So, what brings you here, Yugi?" asked Syrus Truesdale.

"Well, I got a call from Justin saying that there was an emergency." Yugi answered the Roid Duelist.

"Really?" wondered Bastion Misawa. "What sort?" he asked.

"Well, Mako Tsunami here figured out what made those claw marks I saw last night." Justin stated to the Ra Yellow student.

"Yes, indeed." Mako added. "It would seem that there is a werewolf on your campus."

The rest of the students in the common renovated room of the Slifer dorm were frightened to hear that there was a real monster on they're campus.

"A WEREWOLF!" Syrus shouted in horror.

"How in Sam Hill did this happen?" asked Tyranno Hassleberry as he wanted to know.

"I wish I knew." said Aster as he did not know how this happened.

"Well, it might still be out there." said Jaden as he did not know where it was. "If it was at the docks last night, we still might be able to catch it tonight."

"True, but we'd better put the academy on high alert." Justin stated as he did not want to alarm anyone.

"That sounds good." Axle Brodie said as he agreed with this.

"I'm with ya there, mates." Jim Cook confirmed with his accent.


Later that day, we see Bastion wandering around the lounge thinking of why there would be a werewolf on the campus.

"Hmm. I wonder why there would be such a creature lurking around." he said trying to figure this out by pacing the floor. "And what's more intriguing is that Yugi Moto and his friends came here to help with the cause of finding the beast." He said as he was excited to hear about this.

"I wonder what other surprises are in store for us all." Bastion wondered as he walked into the room where Dr. Crowler and Vice-Chancellor Bonaparte were in. "Excuse me, Dr. Crowler, Vice-Chancellor Bonaparte. May I speak with you?" he asked the two guys who wanted to destroy the Slifer Red Dorm in the first place.

"But of course, Bastion." Dr Crowler said as he allowed the Ra Yellow student.

"What is is, monsieur?" the short vice-chancellor asked.

"Well, the new campus detective Justin Desoto just found something incriminating last night." Bastion started out as he put his finger and thumb to his chin. "It would seem that there is a werewolf on the campus. And, Justin has called Yugi Moto, Joey Wheeler, Tristan Taylor, Tea Gardener, Serenity Wheeler, Mako Tsunami, Duke Devlin, Rebecca Hawkins and Mokuba Kaiba here to assist him." Bastion had told them of what the new detective did, and the doctor and vice-chancellor were shocked to hear this sort of news.

"WHAT!?" the both of them said in unison.

"There's a werewolf on the campus?" Bonaparte wondered shockingly.

"AND Yugi Moto is here?!" Crowler asked also feeling the shock. "Whoa! So I take it, the whole school is on high alert?"

"Yes indeed." Bastion replied. "Everyone is still safe in their dorms."

"Well, I hope they'll be safe from that creature." Bonaparte said as he was concerned.

"Well, Jaden, Yugi and Justin are going to look for the creature tonight." Bastion told them as he relayed the plan. "They're gonna try to bait him into coming out into the open, and then send him back where he came from."

"Is that even possible?' Crowler asked.

"I suppose so." the intellectual Ra student told them both. "I was going to ask Justin about what he knows about werewolves. You want to adjourn to his office with me?" he asked the two faculty members.

"Okay." the both said in unison. So they followed Bastion to Justin's office.


We now see them both in the office with Justin. Justin's detective office looked like the living room of his house. It had a couch, love seat, end table's, a lamp and a HD Television set. He also had a cable box to watch his favorite programs. Right now, he was sitting at his desk looking over his computer.

"Hello there, so what is it that I can do for you, Bastion, Vellian and Jean-Louis?" he asked the three men in his room.

"Well, we'd like to know your information on werewolves." Dr. Crowler said as he was eager to know about this sort of thing.

"And, how they re-populate." the vice-chancellor wondered along with the doctor.

"Well, alright." he accepted the request and had them all sit on the couches and he explained everything to them. "Okay, here's what I know about werewolves...They only come out when there is a full moon, for three consecutive nights...Also, they can be killed by a silver bullet, and or anything silver. Another you should know is that some of them tend to travel in clans nowadays...In order for them to turn back into their human form, it must be daylight...If a human gets bitten by one, then they will become a werewolf as well. The symptoms are as followed; 1. The human will get furry. 2. That human's eyes will turn yellow, and they will also grow claws. 3. The human that got bit will also start to have a voracious appetite. Or insatiable craving for meat."

The lot of them were all shocked by what he was telling them. "S-s-s-so how can a human become one such monster?" Crowler asked.

"Well, there are a number of ways." Justin said as he was gonna explain them one by one. "1. You have to be in the bloodline of a werewolf family. But no one here is like that at all. 2. The human would have to get the bite from one. Old school, hardcore. But so far, no one got bit. 3. The human would have to be injected with a dose of LB217 Lycanthrope blood. A big process that depicts the Wolf-Man transformation like we see in the movies. Another thing is that they are known for their speed. So, watch out for their jumping attacks, and keep clear of their fangs."

The doctor and vice-chancellor were still shivering like they were cold. "Well, how do we turn a human back to normal after they got bitten?" asked Crowler.

"Well, it's very simple." Detective Desoto stated to them both. "We have to kill the werewolf that bit that human in the first place. Also, the victim should be able to do that. It's a simple test of will-power really."

"Will power?" Bastion wondered. "You mean like Green Lantern has?"

"Yes." Justin replied. "So, right now we need to prepare for this sort of thing, and make an antidote, just in case." he instructed to the three of them.

"Right." Bastion, Crowler and Bonaparte said in unison as they agreed with Justin's statement. So they got busy and began to work on a way to get this werewolf.


What will happen if Yugi and Jaden encounter this beast by themselves? And will the antidote work? How will our heroes and heroines prevail? Why am I asking you all these questions?
