Showdown with the Possessed

The next day...
Arisa had the key keepers meet her in Chancellor Sheppard's office.
"I asked you to come here because we need to replace one of the Key Keepers."
"Okay, but who is being replaced?" Jaden asked.
"Prof. Banner. He made it clear that he's not a duelist." Arisa answered.
"Okay. So who do we get to replace him?" Kaoru asked.
"I will. It's about time I proved why I'm one of the island's best duelists." Arisa told her sister.
"Just be careful." Davis said. "These Shadow Riders are no joke and I have a terrible feeling we might run into more possessed students."
"But by beating Atticus we were able to free him which means defeating a Shadow Rider shows that we can free a possessed student." Kaoru said.
"Let's just hope it's that easy." Ryan added. 
He knew for a fact it wouldn't be that simple.
"Who do you think the next possessed student will be?" Syrus asked.
"If I had to guess I can think of somebody." Davis said.
"Who though." Alexis added, somewhat confused.
The rest of the group also wasn't sure who else was possessed.
"Alexis, didn't you say Gerard gave you a flash drive of all the missing students?" Arisa asked. 
"He did." Alexis nodded, showing them the flash drive.
"Let me see if I can access the file." Ryan opened up his laptop and plugged the flash drive in.
"Anything so far?" Alexis asked him.
"Yeah. Take a look." Alexis saw a picture on the screen.
"Who is that?" She had never seen this person before.
"Oh no." Arisa said after seeing the photo of a Ra Yellow student. "Zane and I remember this person all too well." 
"Mind telling us more." Ryan remarked.
"Basically there was this one student from Ra Yellow who was making mince meat out of most of the Obelisk Blue students that got in via connections and they made a mockery of Crowler, the blue dorm and Crowler's gender." Arisa spoke. "It was when Zane and I were in our second year. Crowler hoped Davis could defeat them."
"Believe me they were very tough." Davis said. "I had to bring out my Ancient Gear Gadjitron Chimera and Dragon and I still lost."
"They managed to beat you." Ryan replied. "We better take him seriously then." 
"Oh yeah and Davis was one of the only Obelisk Blues they respected despite him being Crowler's protege." Arisa said.
"Probably due to his personality." Syrus guessed.
"It's more to his ability as a duelist." Arisa said. "The thing is the Gadget archetype has changed so Davis has gotten stronger."
"The problem is that Davis lost his key to Camula and so did Zane." Kaoru said. "If the next Shadow Rider is the student we're talking about, then I may have to face them in Davis' place."
"If you do have to duel him, then be very careful." Arisa told her sister. "They say his signature card is Blue-Eyes White Dragon."
They then headed off to class while preparing themselves for a possible Shadow Rider.
Prof. Banner was going over Flip Effects.
"Who can tell me what Fiber Jar does?" He asked.
"I can." Syrus raised his hand. "Fiber Jar returns all cards in the hand, field and graveyard to the deck and both players draw 5 cards."
He had gained more confidence since Zane's duel with Camula.
"Very good Syrus." Prof. Banner smiled.
They were unaware the next Shadow Rider was observing them. Her name was Jerrica, a Slifer Red specializing in Gem-Knights earning her the alias Gem.
'Who will my target be?' She thought.
Her eyes eventually drifted to Arisa.
'Perfect.' She smirked.
Jerrica then exited the classroom.
Classes soon came to a end after that.
'Will we encounter another Shadow Rider today.' Arisa thought to herself.
A few seconds later someone appeared in the woods.
It was another possessed student. They used a deck consisting of fairy type monsters.
'I'll lure one of those Key Keepers to me.' They thought.
Arisa spent the next few hours in her dorm room.
She had been going over the files of the missing students and their deck styles.
"How to prepare for them?" She whispered.
A answer would soon come.
"Let's see." Arisa went over a strategy in her head.
She suddenly saw a silhouette in the forest.
'Who was that?' She thought.
Arisa gave chase to the figure.
"Where are you!" She shouted.
The figure then suddenly appeared in front of her.
"So you're the next Shadow Rider?" Arisa asked the figure.
