Tenjo Hikari had no clue about the "existence invading the Spirit World" that Camilla mentioned.
After all, in the Yu-Gi-Oh world, there aren't many entities that can create such scenarios, but those that can are usually pretty abstract.
Let's say, what if the "unknown existence invading the Spirit World" she's talking about is Yubel?
Considering that in this world, Judai didn't send his cards to the cosmos, but to the Other Dimension.
It's possible that Yubel gained some reinforcement, aiming to stir things up in the Spirit World in order to meet Judai again.
Tenjo Hikari believed Yubel could pull off such a thing.
But the problem is…
I can't imagine a scene of defeating Yubel.jpg
Before the transmigration, no Fusion Spell was needed, not even any action; just showing Yubel and the 0 ATK 0 DEF Archfiend back to the deck would make the Fusion Monster "Phantom of Yubel" appear, leaving Tenjo Hikari with a serious shadow.
I can only say, Fusion is the noblest summoning method.
If you met a Yubel who could play like this, then instead of playing cards, it might be better to directly use Super Polymerization — actually, in the original work, Judai was generally at a disadvantage against Yubel and ended up forcibly merging with Yubel using Super Polymerization to resolve the issue.
Although according to the standards and card strengths of this world, it shouldn't be as bad, yet he still felt apprehensive — because Yubel's schemes were the pinnacle level in "Yu-Gi-Oh! GX"!
After the duel with Vampire Fraulein, a few students immediately sent Marufuji Ryo and Tenjo Hikari to the school hospital, though Marufuji Ryo hadn't especially struggled, but still got hurt and needed treatment.
On the other side, Tenjo Hikari's suicidal charge did result in significant injuries, although not as serious as last time with Darkness, still the external injuries required proper attention.
Along the way, Tenjo Hikari also visited Professor Cronos, who was already lively, proudly listening to some students bragging, occasionally, seemingly subtly boasting about his own style...
Seeing him still so humorous and vain, Tenjo Hikari was relieved.
Taking a moment, Tenjo Hikari checked his deck.
In the original work, after Manjome defeated the Dark Scorpion Burglars, the spirits of the Dark Scorpion Burglars followed him. Nonetheless, in this world, the Vampires surely wouldn't let their empire's second-in-command follow him in card play, hence regrettably only got the Witch's and "Fraulein's" cards, without obtaining the Vampire Fraulein spirit. Marufuji Ryo showed no interest in these cards, thus passed them onto him.
It's worth noting that the "Fraulein" card has a strange 3D model, which Tenjo Hikari suspects might be the coordinates of the "Vampire" Dimension.
Honestly, although life points need to be paid, Vampire Fraulein is still quite useful in this era.
However, considering the ridiculously few Fusion Monsters for Zombie-Type, he couldn't incorporate these two cards. When the opportunity arises and he has the confidence, maybe he will explore the Vampire Dimension.
Although he's not particularly interested in Female Spirits, he certainly doesn't want to see Vampire Fraulein becoming cards like Skelgon or Zombie Warrior.
He meticulously checked his deck and discovered that several cards had changed.
"Uh... Seven Cities of the Golden Land?" Tenjo Hikari somewhat understood the fusion strategy thinking, basically, it's about what type of opponent you duel and what type of card you have, so changing it into other categories, making a "Zombie-Type Fusion" seems reasonable…
Yet…
In his era, there were only 7 Fusion Monsters for the Zombie-Type!
More important is, he doesn't even have "Eldlich the Golden Lord"!
Still, having one more of this card could indeed supplement the lacking backfield cards for him, it's not bad.
"Wow, Master, the spirit on the card image looks really handsome—" The Alchemist who resided inside the card suddenly jumped out excitedly when seeing Tenjo Hikari take out the card for study, pointing at the "Eldlich the Golden Lord," eyes gleaming gold.
"If someday you can conjure gold, maybe you will meet it, keep it up." Tenjo Hikari responded without hesitation, fully supporting him.
The Fusion Monster Eldlich the Mad Golden Lord is pretty strong, and he would be glad to use it if possible.
While Tenjo Hikari was rubbing the card, feeling the card's presence, at the high-rise of the Fusion Department, some people were discussing about him.
"There are already two seven-star failures?"
In the office of the person in charge of the Fusion Department, Akaba Leo sat at the desk, watching the projector, evidently in a video meeting with some individuals.
On the video call, two different images could be seen.
To the left, a large cultivation chamber, inside which an elder with closed eyes was connected to tubes, wearing an oxygen mask, occasionally emitting bubbles; to the right, a person with a mask, cloaked, whose eyes seemed to flash with eerie golden light.
If Tenjo Hikari were here, he'd surely recognize, this masked person was undoubtedly — Teacher Daitokuji!
"Sorry, it appears the two seven-stars I selected failed to meet your expectations." The masked man slightly bowed, "Unexpectedly, they've grown to this extent."
"Armnile, it's not your fault." The elder's machine voiced his thoughts, emitting piercing electrical sounds, "That unidentified Darkness we could ignore, yet that female vampire, a powerful Otherworldly Spirit, losing is a surprise; don't say it was your fault, I am surprised as well."
"More important is, remarkably, both times the same duelist engaged in the duels…" The elder appeared somewhat troubled.
Indeed, the wins or losses of the seven-stars were inconsequential to him.
The concern is, it shouldn't be the same person participating in the seven-star duels each time!
"May I say something on that note?" Akaba Leo clasped his hands on the table, speaking.
"Oh? Dr. Akuma, what insights do you have?" Daitokuji curiously looked at him.
"In both duels against the seven-stars, they had the same duelist, Tenjo Hikari." Akaba Leo continued, "Moreover, besides this, Marufuji Ryo, who also participated in the duels, has his own issues."
"How so?" The elder inquired.
"They—are students of Cronos."
"??????" Daitokuji couldn't help but tilt his head upon hearing this.
"Marufuji Ryo is an outstanding student of Blue Academy, while Tenjo Hikari is an expert with the Ancient Gear Deck, possessing the Ultimate Ancient Gear Golem exclusive to Cronos; in actuality, they are people sent by Cronos."
"Is, is that so?" Daitokuji asked confusedly.
I have no knowledge of this?
"Armnile, you've had too few interactions with Cronos, leading to your unawareness; that guy on the surface appears meek, yet is full of schemes." Akaba Leo continued.
"Huh?" Daitokuji leaned back.
No way?
I've known him for so many years, how could I not know what kind of person he is?
I could easily take him down with one hand!
Moreover, Hikari is my disciple! Mine!
"In short, it's likely that Cronos realized something, thus involving his disciples in the duels, preventing any other intervention!"
"Never thought, my school actually has such an exceptional professor?" The elder couldn't help but express admiration, "Then, what is your suggestion?"
"By means they cannot openly refuse, temporarily preventing them from engaging in the seven-star pursuits!" Regarding this matter, Akaba Leo actually had personal motives, although not disclosed.
"Oh, indeed. As expected from you, Dr. Akuma, as worthy of the scientist I value most." The elder released a lot of bubbles, appearing considerably satisfied.
One Armnile, his most relied upon alchemist; one Akaba Leo, his most valued scientist. With these two individuals, how could he worry about not achieving eternal life?
"Then, I'll think it through.
Alright, understood, I'll organize it immediately…
A dimensional exchange contest that only outstanding students can participate in."
