In summary...
The curriculum is quite perfect.
I have to say, when the professors at Duel Academy really showcase their "true skills," each of them truly has their own tricks.
In the original work, the teachers and professors at Duel Academy were already quite competent, and in this highly developed world due to dimension travel, the skills that these duelists, who became "professors" based on their individual abilities, possess are truly spectacular one after the other.
Perhaps in terms of sheer strength, individually, none of them are comparable to Akaba Leo.
But...
The fact is, there are just so many of them, and they're all very talented.
A number of them, like Professor Cobra, were formidable enough to refuse multiple invitations from Akaba Leo without being affected by the Fusion Army, which speaks volumes about their caliber.
And precisely because of this, Professor Cronos specifically asked Tenjo Hikari to come to the principal's office to hear Tenjo Hikari's thoughts.
He knows his own situation well. He's very clear on where Akaba Leo's "imaginings" about him come from, so he never accepted these accolades. However, conversely, while he doesn't accept them, he always refrains from acknowledging some of the relatively private matters Tenjo Hikari has done.
Because he didn't want Tenjo Hikari's studies to be affected by these trivial or strange matters, and he didn't want Tenjo Hikari to suffer retaliation.
With him as the "mastermind," others would have to show some restraint.
Similarly, due to Akaba Leo's situation, he was also very concerned about these professors.
Yes.
The courses everyone teaches are indeed quite impressive.
But is there any underlying problem?
Could there be any conspiracies or plots like Akaba Leo's?
To some extent, the professors' suspicions were actually correct.
Perhaps the "duel" with Akaba Leo was unintentional for Professor Cronos, but in assessing these professors, he genuinely wanted to understand the situation from every perspective.
So, he arranged the "professor assessments" as best as he could with his own ideas, and then asked for input from Tenjo Hikari, his most trusted student, hoping to identify all problems and doubts as much as possible.
"So, Tenjo-san, do you think there is anything strange about the courses of the two professors?"
Tenjo Hikari thought for a moment and replied, "They both do."
"...Is that so."
"The story Professor Cobra told, you should remember, is from the report given by Lightsworn and Judai after the GX Tournament ended."
He nodded.
Indeed, regarding the Lightsworn, the Dark World, and the situation with "The Supreme King," while Professor Cronos didn't follow it throughout, he did later watch the recordings and content. Now that Tenjo Hikari brought it up, he realized suddenly.
Turns out, that "king's story" was... The Supreme King?
If that's the case, then indeed, it's hard to guarantee...
"What about Professor Seraph? He seems very amiable," Professor Cronos asked, "and his experimental performance is also quite good."
If appearing amiable could reveal a person's heart, then Judai and the others wouldn't have been left bewildered after being thrashed by Teacher Daitokuji.
Tenjo Hikari also didn't know what Professor Seraph was really thinking; he just felt that the ritual for summoning Spirits was indeed very dangerous.
If some strange Spirit takes advantage and directly invades their world, whose responsibility would that be?
Would it be the bad luck of the student who attempted it?
But other than that, Tenjo Hikari couldn't say what was wrong.
After all, whether it was Professor Cobra or Professor Seraph, the content they taught in class was genuinely valuable material. It was exclusive knowledge that world-class researchers and scholars like them focused on, which other professors wouldn't begin to touch.
Moreover, speaking of danger, Professor Cobra's course was almost entirely without it, and while Professor Seraph's course was relatively riskier, the materials for those rituals were strictly controlled by Kaiba Company. Regular students couldn't get their hands on them, and only a professional like him could apply to use them in class. Who else could manage?
In summary, although the courses of the two professors seemed somewhat strange on the surface, they all fell within the "scope" of things.
Fortunately, Professor Cronos hadn't expected to get answers in one day.
After all, he had prepared to observe the behavior of these professors for the entire semester.
The reason he called Tenjo Hikari this time was that he knew Tenjo, as the most studious and outstanding student, would attend all the professors' classes, so he specially reminded Tenjo Hikari to be careful.
"Don't worry about it, Professor; I'm ready."
Tenjo Hikari had always been keeping an eye on Professor Cobra, wondering if he might have any plots, and consequently, he approached the other professors with suspicion as well.
After all, in the original work, each of those professors, indeed, each had their unique skills. There were more than a few who could trick and frustrate Judai to the point of depression. Now, after several rounds of selection, these individuals could only be even sharper and more formidable than the professors in the original work.
Just like Professor Cobra, who was entirely different from Tenjo Hikari's impression.
Professor Cronos nodded, then gestured for Tenjo Hikari to come over. Tenjo Hikari got up and walked over, a bit curious, only to see Professor Cronos secretly take out a small card box and hand it to Tenjo Hikari.
