Summary Scenarios to be Presented (may not be in order):

1. Yugi Moto's sister is an OC for the Yugioh part by my online friend "Rika"

2. Rika and Mizuki reunited as they are close pen-pal friends

3. Cecelia faces against the advanced Duel Monsters system using her newly created and registered Deck

4. Yugi and his friends witnessed the Duel before their very eyes

On the other side of the world, a young teenager is with her twin brother named Yugi Moto. Her name is Mizuki Moto and she's recently playing the game of Duel Monsters for as long as she could remember since Yugi won the Duelist Kingdom tournament. Her hair is a mix of black and golden in a sense with a pair of beautiful light-blue eyes. Standing at 4'8" feet taller, this would make her brother Yugi a few inches taller as he's even in five feet. Yugi's hair features multiple layers including long blond crooked and pointy locks for his fringe. The rest features a set of five large spikes and two smaller spikes colored black with a magenta sheen along the edges. He and his little sister are with their friends in a group as they boarded into the KaibaCorp private jet to Kaiba Land. Mizuki sits in between Yugi and this girl named Rebecca Hawkins as if being the protective little sister. One other girl named Téa Gardner smirked a bit when seeing that happening. Mokuba was with the group when the jet is landing: "Seto is inviting some honorary guests from Tokyo for a big surprise." One other friend with the blond hair and blue eyes named Joey Wheeler asked, "Eh? And who did Rich Boy invite anyways?" Mokuba grinned and said, "He and I have found this rumored Duelist who plays the Lightsworn Deck and she's invited to participate." Mizuki jumped a bit in shock as she said: "No way! That Deck is known to be in the Top 20 Best Decks of all times!" Mokuba nodded and added in more: "And not only that, but the Lightsworn Duelist is also given permission by Seto to verify and legally registered one other special Deck. It's recently created by Pegasus and have been registered as legal under the system of the KaibaCorp. So you might probably see one of the two in person soon." Duke Devlin who is the creator of Dungeon Dice Monsters asked: "And how would we know if it is that said Duelist?" Mokuba answered as he gives the group a tour around Kaiba Land: "Seto has invited even this Pro Hero who calls himself All Might who is recently a teacher for U.A. High." Rebecca said excitedly as she jumped a bit: "I heard about that guy! He's known as the Symbol of Peace to the entire world!" Yugi was then in a mental conversation with his partner in spirit who is referred to as the Nameless Pharaoh for the time being. The Nameless Pharaoh or Yami Yugi in some cases has a more mature appearance, being taller in stature and having a deeper voice in the public. His eyes are also narrower with a more intense, determined gaze. He also appears more muscular. Yami Yugi's hair features multiple layers including long blond crocked and pointy locks for his fringe. Unlike Yugi, some of the blond locks jut upwards. The rest of his hair features five large spikes colored black with red with a hint of magenta on the rims all along the edges:

Yugi: "Hey Pharaoh...is there something on your mind?"

Yami Yugi: "As a matter of fact, Yugi, there is. It's about this dream from last night. About this Redeeming Dragon who is a Lightsworn Hybrid and a Sacred Dragon Slayer who has a task of protecting the world and beyond. The rest is all a mystery to me."

Yugi: "I see...hey. Mizuki was telling me about a friend named Rika who she's keeping in contact. Maybe, this Rika knows who you're seeing in the dreams of yours?"

Yami Yugi: "Well, it is a start to go somewhere."

Mokuba led the group to the place known as the Kaiba Dome that's designed quite like the Blue-Eyes White Dragon. Walking inside, Mokuba was explaining about the latest technology called the KaibaCorp Dueling Computer. It has the top decks from around the world as well as both Kaiba's and Yugi's Decks. He then added in this detail: "One other fan from our company website suggested on setting up the levels from 1 to 5 at the highest so everyone can choose a certain level they're most experienced in." Yugi smiled: "That sounds like an awesome idea!" Mokuba nodded: "Now that I think about it...a fan who was labeled as Mercury have suggested. Wait...could it be...?" Just as he has an idea of who the online fan would be, one of the children called out: "No way! It's the Sports Festival champion Miyamoto! And she's with even All Might himself!" Mizuki got curious as she tries to get a closer look. Looking up, she recognized the fairy childhood friend of Cecelia as her pen-pal friend: "Rika! Is that you?" Rika looks down and a smile widens as she flew down and forward for a spinning hug: "Mizuki!" It took Yugi two seconds to realize the reunion and smiled: "Oh! I get it now. This must be your pen-pal friend you mentioned about, right?" Mizuki nodded her head and grinned: "Mhm! This is Rika!" Tea smiled as she said with a wave: "It's nice to meet you. Mizuki said that you're a fairy and I see that she wasn't lying from your wings on your back." Rika blushed but still lets Mizuki hug her more. Cecelia steps up the stairs from one end of the Dueling Computer as if facig her opponent. She wears her usual U.A. High school uniform as she thinks of setting the level to 2. Kaminari wondered in confusion: "Huh? Why is Cecelia going for Level 2?" Bakugou scoffed: "You idiot Pikachu. That computer must have the top Duelists' Decks from around the world. If she's up against this supposed King of Games' Deck when going up to the toughest level, it would be rather stupid." But just as the Duel was about to start, that's when everyone seees every single exit closed down and locked them all inside. Mokuba tried to get the system going, but he said in a panic: "What's happening? I have lose control." Ami stepped in and connected her super computer in place and said as she got the full scan: "It appears as if someone with a very high intelligence have hacked into the computer setup. Though I can thoroughly go into the system to find the hacker, it might take a lot in my knowledge. I'm afraid that the quickest and most effective way to get everything back to normal is if Cecelia defeats the Dueling Computer in a Duel."

What the Dueling Computer did through the hack was summoning Berserk Gorilla in ATK position with one card facing down to end the turn. Yugi said in shock when looking up at the stadium screen: "Look guys! We got more bad news! The computer sets itself on the toughest level...!" Duke added in as he's getting worried: "And if she loses to that thing, we're going to be locked up in here for who knows how long...!" Cecelia broke the silence and said this with a smile: "It's okay everyone. I will get us out of this imprisonment. And even if I lose once, I won't give up. I will keep on going until everyone is safe. That's one of the true tests of a hero,,,right All ight?" All Might himself grinned and said out proudly: "That's right! We as the heroes will do what we must do and live by our examples of justice!" Rika smiled and called out: "You can do this, Cece! Go for the win for all of us!" Cecelia said as she got her five cards: "I intend to! My turn now!" As she added one card in to make a total of six in her hand, she said: "First, I'm putting down three face-downs and use Emergency Provisions Magic Card. By sending the three face-downs, I now have the total of 7000 Life Points." With one card left and as if it's a stroke of luck, she said: "My final card is the Card of Sanctity. With it, we're both allowed to draw until we each have six cards in our hands...!" Mina said as she tries to think: "Huh? How come she sent those cards into the Graveyard for Life Points?" Bakugou growled a bit and said: "Are you stupid, Raccoon Eyes? With Miyamoto having this much of Life Points, there's gotta be some effects that require a certain amount from her Life Points to activate one or more effects." As it turns out, he was right as Cecelia continued with her turn: "Next, I will activate this Field Spell called U.A. High Academy!" The hologram lets out the field of which looked like the entire school ground and building of U.A. High itself. She added on: "Allow me to explain what it does. It allows me to summon as much of the Quirk Heroes that are students and Pro Heroes that I have in my hand for 500 Life Points each. And I have the total of four each!" This is when she sets four Duel Monsters on the field by the effects of the Field Spell Card:

Quirk Hero Izuku Midoriya:
ATK: 1400
DEF: 1000

Quirk Hero Bakugou:
ATK: 1600
DEF: 1300

Quirk Hero Eraserhead:
ATK: 2100
DEF: 1500

Quirk Hero All Might
ATK: 2500
DEF: 2100

Cecelia then said this as she has one more card left in her hand: "I'm afraid that this is the end for you. During the Battle Phase, I'll activate the effect of Quirk Hero Midoriya as it doubles his ATK points from 1400 to 2800! And it's okay if he will be in DEF position soon after for two turns because I have the other three to follow suit!" Quirk Hero Midoriya charged in at Berserk Gorilla and shouted as "he" threw in the punch: "Detroit SMASH!" This lowered the computer's Life Points from 4000 to 3200. Everyone is in shock to see the full action in a hologram as Berserk Gorilla is gone. That's when the remaining three attacked directly with the total of 6200 ATK points. The computer "stated" as it turned itself off: "Game over..." The lights turned back on and every exit in the building opens up as Rika smiled for the little children that were frightened before. Cecelia walks down the stairs with her new Deck in her hand and Uraraka cheered happily: "Hurray! You did it Cecelia! You won!" Ami giggled when standing beside Iida "It is probably one of the quickest victories ever." Iida nodded: "Yes! As Class Representative, I call this a celebration for those of us in distress!" Yami Yugi looked onto Cecelia as his eyes widened. Yugi "speaks" from his mind at his partner: "Pharaoh? Are you okay?" Yami Yugi answered from their spiritual communication: "That girl...she seemed to assemble the hybrid deity that I saw in my dreams. If that's the case...it's likely that she's is someone who we could trust on finding my lost memories."
