In front of the rundown Red Dormitory, Teacher Daitokuji was pushing a massive machine, sticking out his tongue to cool down while greeting Tenjo Hikari.
"Te... Tenjo-san, h... hello."
He looked quite exhausted.
Teacher Daitokuji's full name isn't clear; only that either his last name or first name is Daitokuji, with black hair, wearing a white shirt and a tie, glasses on, a friendly smile, giving off a warm and approachable vibe.
"Hello, Teacher Daitokuji."
This Teacher Daitokuji is not only the advisor of the Red Academy but also its chef, and part-time "Alchemy" teacher at the academy, holding quite a significant position, though he often appeared weak, which led to frequent bullying.
But Tenjo Hikari knew that Teacher Daitokuji wasn't as weak as he appeared; on the contrary, he was a truly formidable figure, a genuine heir of Alchemy, and even capable of creating the "Philosopher's Stone" as a superstar Duelist.
Throughout the academy's divisions from southeast to northwest, he was likely one of the top duelists.
The "Macro Cosmos" card that many duelists feared was his exclusive card.
"Teacher Daitokuji, why didn't you call us to help lift it together? This looks exhausting!" a student resembling a sloth said aloud.
He was a dorm mate of Judai, Maeda Hayato.
"Hmm... hahaha, I got a bit excited with students from other academies coming, meow~"
A grown man actually said "meow", and hearing it up close gave one goosebumps.
"Oh, right, Tenjo-san, come and test your Spirit Adaptability."
"Spirit Adaptability?" A new term, Tenjo Hikari leaned forward and extended his hand to let Daitokuji scan it with a machine.
"Hmm... as I thought..." he muttered, glancing at the values on the machine, then smiled again and said, "Tenjo-san's Spirit Adaptability is also 4 stars, just like Judai's! No problem in participating in simulations, meow~"
"Wow, it's just like my brother!"
"Haha, Tenjo, I knew you'd have no problem—"
Tenjo Hikari was a bit confused.
"Anyway, what's the situation?"
"It's about accepting Spirit Duel adaptability; the higher the star level, the better rewards you get, the less mental strain, and the shorter the recovery time needed when we return to our dimension.
It's said Mr. Muto Yugi possesses a LV 12 adaptability; no matter how powerful the spirit is, it bows before him! Even when dueling in other dimensions, he doesn't feel tired returning to our world, the true Duel King, meow!"
"Alright, come on, Judai, Tenjo-san, we are now before the Dimension Gate, I'm going to start the teleport, meow~" Daitokuji pressed the button on the Dimension Gate, speaking while murmuring.
"Teacher Daitokuji, this machine looks pretty worn out!" Marufuji Shou couldn't help but feel concerned.
Because this machine indeed appeared rather aged.
Appearance-wise, it wasn't different from the Dimension Gate of the Fusion Department, but it looked old and rusted in places, with components sounding like ping-pong, clearly an outdated model retired long ago, incomparable to other academies.
"No choice, meow, Red Academy only has this one~ don't worry, I've regularly maintained and personally modified it!"
Marufuji Shou and Maeda Hayato were still uneasy, yet Tenjo Hikari let out a sigh of relief.
After all, Daitokuji was a powerful Alchemist; if he had repaired it, the machine should be fine.
"Come on, stand properly, stand properly, meow~"
Excitedly, Judai stood at the machine's front, and Tenjo Hikari curiously stood beside him, observing the machine.
The enormous metal ring began rapidly spinning; soon, strange purple-white rays started mixing and twisting, shining on Yuki Judai and Tenjo Hikari.
"Wow, so this is dimensional teleportation?" Judai shouted excitedly.
Tenjo watched his body undergo color-change, turning into particles, feeling amazed.
Here comes another "crossing over"!
Just then—
"Meow ah!!!" Suddenly, Daitokuji shouted in panic, and immediately, the machine's light changed colors drastically, seeing Daitokuji flustered, he quickly spoke, "Wha, what's going on, machine error!"
"Ah!?"
"Teacher Daitokuji!!"
Marufuji Shou and Maeda Hayato rushed frantically to him, watching Daitokuji frantically pressing buttons, face distressed: "Quick, stop it, stop it!"
"No can do, can't be shut off once activated!"
"How come!"
Meanwhile, the rays shining on the two gradually changed from purple-white to intense golden!
"What's going on, Teacher Daitokuji?" Judai still concerned about Daitokuji.
"Meow———"
But time was running out.
After a scream, Tenjo Hikari and Judai disappeared from this world.
Upon looking back again, Tenjo Hikari noticed that the surroundings had drastically changed.
He and Judai seemed to be in a massive prison, the air unbearably thick and dusty, Tenjo Hikari waved his hand and brushed the dust, feeling suffocated.
"Cough cough cough... where are we?"
"Unsure, maybe machinery fault transported us elsewhere?" Tenjo Hikari hesitated.
Indeed, it seemed tough to figure out.
Given Red Academy's status in Duel Academy, the odds of such incidents weren't low.
But on the other hand, it might have been Daitokuji deliberately tricking them.
After all, in the original work, Daitokuji frequently sent Judai to face Darkness Duel or Spirit Duel.
Considering this world had such a convenient Dimension Gate, Daitokuji tricking Judai seemed plausible?
"Alright! Tenjo, let's go adventure!" Upon realizing an unexpected situation arose, Judai easily accepted the reality, "As long as we beat the spirits here, we can go back!"
By now, he had already faced Darkness Duel, Jinzo, and Gravekeeper Race spirits, and became familiar with supernatural matters; even though he got tricked again, he wasn't worried at all, laughing while preparing to move forward.
"Wait, Judai—" Tenjo Hikari intended to call him back, suddenly feeling the earth shaking, he steadied himself, looked nearby, outside the giant prison, countless flames burst forth, and at this point, Tenjo Hikari finally realized.
Turns out he really was inside a prison!
"Intruders!"
A commanding voice echoed to them, and they looked outside together, seeing an armored figure dark, helmet authoritative, shield in the left hand, sword in the right, gold-and-silver adorned, a voice that seemed to stir the heavens, a supremely powerful warrior.
This was someone any duelist would recognize, "the strongest warrior"!
"Black Luster Soldier!!?" Tenjo Hikari and Yuki Judai shouted in unison.
Immediately.
They saw countless warriors in the Black Luster Soldier's rear plaza—
Where did they come from!?
This wasn't Broken Dimension at all!
This was actually the Black Luster Soldier's headquarters!
