Facing Raizou and Torimaki

One day...
The Shiba siblings were walking around the main building at the Academy.
"Something feels off." Kaoru observed.
"What do you mean?" Arisa asked.
Instead of answering, she took off in a sprint.
"Hey, get back here." Davis demanded.
She ignored her brother's demand and kept running.
A few minutes later, they came across a Obelisk Blue giving a Slifer Red a hard time. A Ra Yellow named Dmitri was watching the whole thing.
"What do you think you're doing?!" Davis yelled.
"What does it look like." The Blue sneered. "I'm showing this Slacker who's boss." 
"Oh really." Davis remarked. "Let's see who the boss is after our duel." 
"You got yourself a deal." The Obelisk accepted the challenge.
They all made their way to the arena.
"Time to show you what being a Obelisk really means." Davis told his opponent.
"DUEL!"
Davis: 4000
Raizou: 4000
"I'll begin." Davis drew his sixth card. "With Ancient Gear Soldier."
Ancient Gear Soldier: 1300/1300
He had grabbed Crowler's deck after accidentally bumping into him.
Jaden and his friends sit next to Kaoru in the stands.
"What's the duel about?" He asked.
"Davis and I caught Chazz's lackeys picking on a Slifer and now Davis is teaching them some manners." Kaoru said.
"I see." Jaden said.
"I'll end my turn with that."
"Let me show you how winners do it." The Obelisk drew. 
"I summon Stealth Bird in defense mode."
Stealth Bird: 700/1700
"Then I play a face down and Stealth switches to face down defense position."
'Next turn Stealth Bird will flip face up and deal me a thousand points of damage. I need to deal with it now.' Davis thought.
"My move." Davis drew. It was Mystical Space Typhoon.
"I summon Ancient Gear Knight." 
Ancient Gear Knight: 1800/500
"Before I attack I activate Mystical Space Typhoon to destroy the card you set last turn." It was Gravity Bind.
"Attack." Ancient Gear Knight destroyed Stealth Bird.
"Go after his life points." Davis ordered.
Raizou: 2700
"I end my turn."
"Davis is handling Raizou with ease and that's Crowler's deck." Kaoru said.
"Why does he have it anyway?" Syrus asked.
"He took it by mistake after bumping into Crowler." Kaoru informed him.
"At least I'll know what to do if I have to face the Ancient Gears." Syrus said.
"My move." Raizou drew.
"I summon Nimble Momonga in defense mode."
Nimble Momonga: 1000/100
"Your move. You won't beat me." Raizou sneered.
"Don't be so sure. My move." Davis replied, drawing a card.
"I sacrifice Ancient Gear Knight and Soldier to summon Ancient Gear Golem."
Ancient Gear Golem: 3000/3000
"Attack Nimble Momonga with Mechanized Melee." Ancient Gear Golem's fist bypassed Nimble Momonga and struck Raizou.
Raizou: 0
"By the way, this is for you." Kaoru handed Jaden a card.
"Fusion Weapon?" Jaden blinked.
"You run several level 6 Fusion Monsters so this will make them a lot stronger."
"Thanks." Jaden said gratefully.
"Bastion, what do you think?" Kaoru asked. "Did you see how Davis handled the Ancient Gears."
"I must admit he did as well as Crowler did with that deck." Bastion told her.
"Imagine if he added some gadgets to his deck." Syrus said. 
"Hey!" They heard a angry voice yell.
Torimaki, another of Chazz's lackeys approached them.
"You're gonna pay for that!" Torimaki shouted.
"Bill me." Kaoru snapped.
"That's it." Torimaki gritted his teeth. 
"Bring it."
"I challenge you to a duel."
"You're on. Name a place." She agreed to the duel.
Kaoru and Torimaki headed to the Obelisk Arena for their duel.
They took their places on both sides of the arena.
"Hope you're ready." Torimaki sneered. 
"Duel!" They both said.
Kaoru: 4000 
Torimaki: 4000
"Winners first." Torimaki drew his sixth card. "I summon Luster Dragon in attack mode."
Luster Dragon: 1900/1600
"Then I place one card face down and end my turn."
"My move." Kaoru drew. 
"I play Elemental Hero Stratos in attack mode."
Elemental Hero Stratos: 1800/300
Another Hero monster was placed into her hand.
She then placed a card in her Spell and Trap Zone.
"Now I use H-Heated Heart to increase it's attack." Stratos was powered up.
"Attack Luster Dragon." Her hero threw a punch and Luster Dragon shattered.
Torimaki: 3600
"You're gonna be sorry." He growled.
"Yeah, yeah make your move."
"Grr." Torimaki angrily drew a card.
"I summon Lord of D in defense mode."
Lord of D: 1200/1100
"Then I activate the continuous trap, The Dragon's Bead."
That was all he could do at the moment.
"That all. Guess I'm up next." Kaoru drew.
"Say hello to Elemental Hero Ocean."
Elemental Hero Ocean: 1500/1200
"Take Lord of D. out with Big Wave Crash."
"With your field empty, you're wide open. Stratos attack." Kaoru ordered.
Torimaki: 1800
'This shouldn't be happening.' Torimaki thought.
"My move." He drew.
"I summon Masked Dragon in defense mode."
Masked Dragon: 1400/1100
"Your move." He said.
"She's backing Torimaki into a corner." Bastion commented.
"Can she get past Masked Dragon though?" 
"This is Kaoru we're talking about." Jaden said.
He, Syrus and Chumley came across the duel in progress.
"Now I use Polymerization to fuse them together."
Elemental Hero Sunrise: 2500/1200
"And that's not all. Next I use Miracle Fusion to summon Elemental Hero Absolute Zero."
Elemental Hero Absolute Zero: 2500/2000
"Now I'll have Absolute Zero attack to activate the effect of Sunrise." Masked Dragon exploded.
"Kaoru has this in the bag." Syrus said.
Absolute Zero and Sunrise wiped out the last of his life points.
Torimaki: 0
"How could I lose?" Torimaki asked himself, punching the ground.
"He let his ego get the better of him." Bastion said.
"Nice job." Jaden cheered for her victory.
"Yeah!" Syrus exclaimed.
Ryan, Davis and Arisa nodded.
"I'm impressed." He said.
"That's Kaoru for you." Davis said.
"Maybe that will teach you not to mess with people." Arisa added.
"Nice job."
