Hi there ! New chapter for this story. I won't dwell for long on that. That chapter was supposed to be longer, but I decided to do the next duel in... the next chapter. And the final two bits are just developping what is going to happen in future chapters.

Chapter 2 : Mock Battle ?! Mastering Pendulum !

After Yuya's victory over the Sledgehammer, You Show Duel School was literally under assault from so many new people that wanted to enroll, because they wanted to know "how to use the Pendulum". Shuzo Hiiragi had decided that the way to go was to set a Duel between Yuya and his daughter Yuzu, so he could show them quicker how to use them. Yuya was hesitant to show them, since the only Pendulum cards available were actually his own, and the fact he hadn't used them before his duel with the Sledgehammer. His father hadn't told him how to properly use them before leaving.

He accepted the duel nonetheless. So he was facing his best friend (that most people in school were pretty sure he would date at one point or another.)

Shuzo quickly set the Action field "Plain Plain", and Yuya got the first turn, summoning his Hip Hippo and start running around on his back

- "Stop goofing around, Yuya ! How old are you ? 10 or freaking 17 ?!"
- "No need to be so serious, Yuzu. It's your turn."

Yuzu drew a card.

- "I called to the stage Aria, the Melodious Diva ! Come, and sing a song to captivate the attention of that hippo, Piercing Note !"

Yuya grabbed a card off a nearby bush, and activate it. Lucky for him, it was "Evasion". Thus, Aria's attack is negated and his Hippo saved. Said Hippo started to spin in the air, prompting Yuya to call "Rolling Hippo !" much to the delight of the audience.

- "Sorry to spoil the fun, Yuya, but when Aria doesn't destroy a monster, I can still deal you damage ! Aria, use Resonating Wave !"

Yuya is caught by the shockwave and lands on his butt. Yuya could hear Yuzu laughing, something that was supposed to sound evil.

- "So, you're playing the bad guy, and I'm the good one, I guess ?"
- "Exactly, now go back to your feet. Kicking you down would be too easy. They want to see your Pendulum. I'll just set a card."

Yuya looks at the children's face. It was clear to him they wanted to see it. The problem is, as he had kept this deck in his room until he had to face the Sledgehammer, he was himself discovering how the mechanic of the Pendulum actually worked, because his father hadn't told him before going off who knows where. He draws Timegazer Magician.

"So, I know it works when I use Timegazer and Stargazer. Dad told me they were Scale 8 & 1; respectively. He didn't tell me where the scales were located. And those kids want to see the Pendulum… I'll bring it to them !" he thought, before making his move. He took Odd-Eyes Pendulum Dragon and Timegazer, shot a look at them. He found the numbers "4" and "8" just on the side of the Pendulum Effect description.

"With Timegazer Magician and Odd-Eyes Pendulum Dragon, I set the Pendulum Scale !"

The two pillars of blue light reappared and the monsters were waiting. Unbeknownst to Yuya, who was too caught in the moment, the numbers "4" and "8" were shown under Odd-Eyes and Timegazer, respectively.

"Swing, Pendulum of Souls ! Draw an arc of light across the ether ! Pendulum Summon ! Come, my monsters !"

There was a beeping, and the Duel Disk had an error message. Yuya looked at it, dumbfounded. Before thinking it was because he wasn't in a pinch. He summoned Whip Snake and used its effect to switch Aria's ATK and DEF, then attacked her with it. But the pinkette girl retaliated with an Evasion Action Card. Yuya had no choice but end his turn with a facedown. Yuzu drew a card "Sonata, the Melodious Songstress".

- "When I control a Melodious Monster, I can Special Summon my Melodious Songstress Sonata ! Then I can tribute Sonata & Aria to summon Mozarta the Melodious Prodigy Maestra ! And by using her effect I can summon another Melodious Monster. It will be another Aria ! Then I activate a Magic Card : Fortissimo, to give my Aria a 500 ATK boost !"

Yuya was wondering if Yuzu didn't go easy on him on her previous turn. He also realised the Odd-Eyes card was visibly beeping on his screen. He tapped it, and read the Pendulum Effect of his dragon : "Once per turn, you can reduce any battle damage involving a Pendulum Monster you control to 0. Also, during the End Phase, you can destroy this card, and add one Pendulum Monster with 1500 ATK from your Deck."

- "What an idiot I am. I could have used that ! Now I need to survive two of Yuzu's turn to do that…"
- "If you're done thinking, noodle brain, my Aria will attack that Hippo ! Piercing Note !"

This time, Yuya didn't have the time to go for an Action Card, and his hippo was destroyed. Yuya's Life points dropped to 1900. Yuya had actually tried Pendulum Summoning Sword Fish, but it didn't work, and he received an error message, as Whip Snake was destroyed by Mozarta, Yuya's life dropped to 1000, and Yuzu ended her turn with another facedown. Yuya drew a card, it was called "Performapal Reborn Force".

- I set a card facedown, and a monster in facedown defense mode, and… end my turn by using Odd-Eyes Pendulum Effect. I destroy him to add Stargazer Magician to my hand."

His set monster was obviously Sword Fish. If he was lucky, he would survive this turn.

Yuzu drew a card, and just launched an attack with Aria on the Facedown, revealing Performapal Sword Fish.

- You activated my trap, Yuzu ! Performapal Reborn Force ! I can only activate this card when a Performapal Monster is destroyed…
- I respond with a trap of my own, Musical Mayhem ! For each of my Melodious monster, you take 800 damage !
- But when I activate it during the Battle Phase, I forcefully end it ! And I can negate that damage, and you will take it instead !
- Not if I can do something about it ! I activate another Musical Mayhem ! I'm afraid you've lost, Yuya."

It was true. It was supposed to be a mock battle to showcase the Pendulum Summon, and he had lost. Most kids just stayed there, until Yuya showed up, and they asked to see the cards Yuya used to Pendulum Summon.

Yuya showed Stargazer, Timegazer and Odd-Eyes. The cards had half regular orange, half green background.

- "And you can't Pendulum Summon unless you have these ?" asked a kid
- "Yup, that's right. And I don't know if there's any other cards, aside from my dad and mine."
- "That's weird… how come we never heard of it ? I think you've cheated against Ishijima…"

One after the other, the other kids agreed, aside from Ayu, Futoshi and another one, that decided to enrol to You Show Duel School, to the pleasure of Shuzo Hiiragi.

In the LDS Building though, a man in a grey suit entered the president office.

- "President, as you asked, we did a check on Yuya Sakaki after he used Pendulum Summoning. He's 17, scolarised in Maiami City Senior High School. As for his duel record, he doesn't qualify for the Championship yet, with 26 victories in 46 matches."
- "Anything worth mentioning on him, then ?" asked Reiji Akaba, president of Leo Corporation.
- "He's the son of Yusho Sakaki, who went missing 6 years ago."

Reiji replaced his glasses, a gesture he was doing a lot.

- "Interesting. Anything else ?"
- "No sir. Do you want us to get these cards ?"
- "Nakajima, I want you to get these cards for analysis here. No matter how. I want them to be used in a Leo Corporation facility. And you know why. Call him."
- "Right away, sir."

Nakajima push a few buttons on his tablet, calling someone, then that someone seems to answer.

- "What is it, Nakajima-san ?" it asked
- "We have a job for you. As a student of Leo Duel School, would you deny this chance to acquire unique cards ?"
- "Unique, you said ? I'd never let such an opportunity pass. What's the job ?"
- "We need you to get Yuya Sakaki's Pendulum Cards. No matter the way, we want them to be used in Leo Duel School's grounds".
- "Got you, boss."

The communication got cut, and Nakajima turned to his boss

- "Can we trust him, Nakajima ? While being one of our best "Standard" elements, I'll say he lacks certain… qualities to go beyond that. Anyone from Fusion, Synchro or Xyz Course could have done a better job."
- "I'm not certain about that, President. Sure we could have sent anyone, but this guy can be rather… cunning, when he wants, and I'm not talking about his dueling style."
- "I'm trusting your judgement. How is advancing our… other thing ?"
- "We are getting informations from some of the international schools that wanted to apply for qualifications in the Maiami Championship. We can confirm that LDS Anatolia will be sending a Fusion duelist along. LDS Arctic will be sending a Synchro Duelist. Two have caught our attention, nonetheless : Neo Domino City Duel School and Heartland Duel School. Should we let them in without investigating ?
- "What are they focusing on ?"
- "Heartland seems to be focused on Xyz Summoning, while Neo Domino is centered on Synchro."
- "Let them in. This should be… interesting."
- "Yes sir, I'll let them know"

Somewhere in the city, two people are chatting, sitting at a café. One was sporting a blue trenchcoat, while the other was dressed in greyish colors.

- "Are you sure about that ?"
- "100%. From what we gathered, and that was fairly easy, Leo Corporation's founder disappeared 6 years ago, leaving his son in charge of the company. He has done a pretty good job, since then, If I'm being honest, but that's besides the point. Would you please go back and report that to the Queen of Ice ? I'm pretty sure they would like to know anything we learned."
- "Exactly, but that's not much to report, I'm afraid, 'Birdman'"

They turned to the voice. Cloaked in a big white trenchcoat that was hiding most of his attire, save for the white boots, and the spiky red & blond hair.

- "Oh, that's you, Sir."
- "Yep, The Queen of Ice sent me to help you guys"
- "You mean, you two had an argument and you decided to come here and let out some steam ?"
- "Remember who you're talking to, Birdman. Anyway, we received a word. Entry in the Maiami Championship is accepted. Go back and tell The Seventh One we can send more people in for that. And say hi to the Queen of Ice for me."
- "Understood."

They finished their drinks and disappeared in a back alley of Maiami
