Learning a Lesson

It had been quiet lately following the defeat of the recent Shadow Rider.
Most of the Blues however hadn't changed the way they act towards the Slifer's and Ra's.
Fortunately some of them decided to do something about it.
"Looks like they need to learn the hard way." Kaoru said to herself.
She and her siblings were going to cooperate with Ryan.
They headed in the direction of his room and knocked on his door.
"Can I help you?" He asked after opening it.
"We would like your help to deal with the rest of the Obelisks." Kaoru stated.
"Frankly things haven't changed a bit." Davis said.
"And I'm gonna be leaving soon as part of the graduating class and I don't want Tyson to have to deal with this kind of crap when he arrives next year." Arisa added.
"Why come to me? Wouldn't Zane be a better person to handle this?" Ryan questioned.
"Zane's about to graduate and so is Arisa." Davis said. "The only catch is Arisa wants to go into law school in case her dreams of becoming a professional duelist don't work out."
"And besides you're the only other Obelisk boy we trust." Kaoru said.
"That's a lot to put on one person, but I'll try my best." He held his hand on the back of his neck.
"Don't worry, we're going to help you." Davis said.
"Well, count me in." He replied. 
"Good to know." Kaoru nodded.
With that settled, their plan could now commence.
"Where should we go first?" He asked.
"Start with the Blues who bully students from the lower ranks." Davis said.
That was a good way to begin.
Their first target was Raizou.
They found him walking down the hall.
"Hey." Kaoru called out. 
"What do you want?" Raizou rudely asked.
"We want you to stop bullying the Slifer's and Ra's." Davis told him.
"Yeah right." He scoffed. "Go away."
Raizou wasn't going to be bossed around by t hem.
He walked away from them.
"What? Are you a coward?" Kaoru mockingly asked.
He turned and angrily looked at her.
"Fine, you wanna a duel. Let's go."
Raizou led them to the dueling arena.
They stood on both sides of the arena.
"Get ready to lose." Raizou sneered.
"Same to you." Kaoru retorted.
