Kagurazaka.
Originally a student from Yellow Academy in the story, after losing to Marufuji Shou from Red Academy, he couldn't handle the "humiliation" and stole Muto Yugi's deck on display to have a rematch with Yuki Judai, only to lose to Judai again.
After losing to Judai, he began to mimic Judai and started using a Hero Deck, making him a rather peculiar student.
His greatest ability is not anything else but his strong memorization skills and ability to analyze duels, which allow him to almost perfectly use a deck as soon as he gets it.
Moreover, and even more impressively, although he is not the chief of Yellow Academy, even with a deck like Muto Yugi's, he can use it just like the original person without ever having a dead draw!
When using Muto Yugi's deck, he can almost perfectly imitate Muto Yugi, making him a very talented student.
He belongs to the type of student whose talent isn't very high but whose lower limit is very high.
As a student of Yellow Academy, Tenjo Hikari naturally isn't seeing Kagurazaka for the first time, and honestly, the two are somewhat familiar with each other.
He still maintained his peculiar appearance, wrapped in a scarf, with a hairstyle reminiscent of Duel King Muto Yugi, dressed in a yellow and white student uniform, looking quite spirited.
Although many students joined the Integration Department for powerful cards, it was clear he didn't need to. After all, in the original story, Kagurazaka was a duelist who held the "Ancient Gear Golem," and he surely didn't need to borrow a deck that even lacked an Ancient Gear Golem.
Is Kagurazaka the opponent? Thinking about it carefully, it makes sense.
Kagurazaka can nearly perfectly utilize the potential of each card, so if he could get the "Duel King's cards," his deck's power would naturally increase.
Moreover...
Tenjo Hikari recalled.
This world never had an exhibition of the "Duel King's deck," instead, there were various activities related to the Other Dimension, so indeed, he had no opportunity to steal any deck.
So in other words, he probably didn't learn to use Heroes like Judai, did he?
What deck would he use?
"Both sides ready!" The teacher raised his hand.
"Duel!"
"Duel!"
"Hahaha, Tenjo Hikari!" Kagurazaka laughed loudly, "I've been wanting to duel you for a long time!"
Is that so?
Why didn't you just tell me before?
Dueling with a high-level Duelist can provide better energy for Super Polymerization to fuse more impressive cards, and after half a year of dueling, Tenjo Hikari discovered that dueling different types of duelists results in different cards, aside from those difficult to create like Midrash, most can be identified in just three or four days.
Kagurazaka is an extremely excellent student; if you invite him for a card game, he surely won't refuse.
"My turn, draw!" Kagurazaka drew a card forcefully, then laughed while showing it to Tenjo Hikari, "Equip Spell, Future Fusion!"
??
Tenjo Hikari was stunned.
Professor Cronos had acquired Time Fusion and Junk Fusion for him, and the version of Future Fusion was still on its way in this world. Thus seeing this card was quite a surprise.
"Surprised? Tenjo Hikari!" Kagurazaka laughed heartily, "This is the power I pursue, the pinnacle of fusion! My Future Fusion surpasses your Future Fusion!"
"You little..." Tenjo Hikari couldn't hold back, "Are you today by any chance..."
"I activate the effect of the Equip Spell Future Fusion, choose a Fusion Monster from my Extra Deck, and send the decided Fusion Material Monsters from my deck to the Graveyard."
"I choose Labyrinth Tank from the Extra Deck and send Giga-Tech Wolf and Cannon Soldier to the Graveyard for a Fusion Summon and equip this card!"
"Fusion Summon, Labyrinth Tank!"
A classic tiny red vehicle emerged from the ground, appearing directly opposite Tenjo Hikari.
He couldn't help but slap his own face.
Darn paper.
Labyrinth Tank, LV 7, Dark Attribute, Machine-Type, ATK 2400.
"See, Tenjo Hikari, your Future Fusion needs to wait for two more turns into the future, while my Future Fusion can perform fusion right now! This is the [Future]!" Kagurazaka boasted confidently.
In the audience, Manjome slowly walked to his friends, casually greeting Judai and the others.
"Is Kagura using Tenjo's deck today?" he mentioned offhandedly, with almost no change from usual.
"Yes." Mitsuzawa Daichi shook his head on the platform, "Clearly such a talented person... Speaking of which, Hikari's deck has many Fusion Spells that only he uniquely possesses, how will Kagura build a deck?"
"It must be mixed with cards from his fellow Integration Department students." Asuka noticed the differences in details, "Although Tenjo-san pursues Fusion, he's actually friendly to others, like users of Ritual Summon or Xyz Summon, he doesn't belittle them. According to Ryo, he also gets along well with duelists from the Other Dimension.
And even within the Fusion realm, he only dislikes those senior students and some irrational classmates from the Integration Department."
"Quite observant, Tenjouin."
Although they were all curious about the "Direct Battle with God's Monster," everyone had their own decks and thoughts, so they didn't sign up for the competition, simply serving as a cheering squad for Tenjo Hikari.
Having been locked up once by Teacher Daitokuji, their relationship had only grown stronger.
"If it's two Hikari dueling, that really sounds interesting." Judai leaned against the railing, cheering for Tenjo, "Hey, Hikari! You can do it!"
"Oh, I will!" Kagurazaka turned his head, directly shouting back at Judai.
"Uh..." Judai awkwardly retracted his hand, a bit bewildered.
"Setting two cards, it's your turn! Tenjo Hikari!" Kagurazaka ended his turn with a shout.
Tenjo Hikari couldn't help but rub his head.
It was the first time in a duel that he felt an inexplicable, abstract, indescribable feeling beyond "passion," "anger," "happiness," "pain," and "helplessness."
"Forget it... my turn, draw." Tenjo Hikari glanced at his hand, "Quick-Play Spell, Junk Fusion, banish Fusion Materials from your Graveyard for a Fusion Summon!"
"Fusion Summon, Labyrinth Tank!"
A blue tiny vehicle leisurely rolled out onto Tenjo Hikari's field, then noticing the one opposite, it beeped as if expressing confusion.
What's going on? Boss, what are we playing today?
"Too naive, Tenjo Hikari!" Kagurazaka activated his set card, "Trap Card, Bottomless Trap Hole! When a Monster with 1500 or more ATK is Summoned·Special Summoned·Flip Summoned successfully, destroy that Monster with 1500 or more ATK and banish it!"
Bang!
The newly appeared vehicle hadn't had time to crash into itself before it found the ground beneath it giving way, causing it to fall and shatter into pieces, disappearing from the field.
"This really isn't a card Hikari would use." Mitsuzawa sweat on his forehead, "Not very fusion-friendly..."
"How about it, Tenjo Hikari, any more tricks up your sleeve?"
Tenjo Hikari subtly raised an eyebrow.
"Forget it... then, Continuous Spell, Brilliant Fusion."
