After the show, Tenjo Hikari first went to check with the Kaiba Company staff about the situation nearby. After reviewing rescue requests and call requests, he found no issues. Only then did he find some time to lie on the sofa in the single dormitory, contemplating life.
D/D/D Oracle King d'Arc.
The prototype is probably St. Joan or Guardian Angel Joan, but since this card is the Archfiend version, perhaps it's fitting to call it "Dark Joan of Arc"?
But none of that matters.
What matters is that this card is part of the "DDD" series of cards.
Which is the same series as the "D/D Swirl Slime" card that Tenjo Hikari obtained after dueling with members of the Fusion Army.
But unlike how he created a D/D Slime himself, this particular card was actually given by Akaba Leo to Saiou. This fact is what makes it so puzzling.
Regardless, in this world, despite the unfolding events diverging from the original story, there are some aspects that closely follow the "original work."
Such as Judai's The Supreme King Power, Ed's innate destiny, John's Crystal Beast—these are things that are part of the original story. Like Ed, whether in the anime or the manga, he lost his father and inherited the unique Hero series cards.
Similarly, the Tyler Sisters have their unique traits that are featured in "Yu-Gi-Oh! A5."
This is a mixed world, and many things cannot be calculated according to the plot of the original story, but a lot of things are similar or even identical to the original.
Uniquely, the "DDD" series belongs to the person who should least possess it!
Because DDD is Akaba Reiji's deck!
Akaba Reiji is the son of Akaba Leo and the leader of the Basic Dimension who most wants to overthrow Akaba Leo!
The father-son relationship that is a joke to others takes on a different meaning for Akaba Reiji, who always seeks to maintain multiverse peace, yet harbors hostility toward his father, who invades other dimensions, including "their homeland."
Akaba Reiji challenging Akaba Leo is the actual main storyline of "Yu-Gi-Oh! A5"!
This is unquestionably Akaba Reiji's doing.
Therefore, the fact that the egg-headed Saiou possesses DDD cards genuinely surprises Tenjo Hikari.
It seems the egg-headed Saiou brought a lot of good stuff from his dimension with him when he arrived in this dimension.
Tenjo Hikari is actually quite pleased as he holds Dark Joan of Arc.
As a standalone card, although its power isn't very high, it has flexible Fusion Conditions—requiring only two "D/D" monsters—and its effect is such that any damage dealt to oneself is converted to life points recovery as long as this card is on the field.
Simple, yet useful, and quite good in this world.
Tenjo Hikari rummaged through his backup cards for a while and eventually found "Dark Contract with the Swamp King" and "Forbidden Dark Contract with the Swamp King." These cards had previously been collecting dust, but finally, he now has an opportunity to consider using them.
Although Tenjo Hikari doesn't currently need to use the DDD series cards, where there's one, there's two, and they're also part of a general Archfiend-Type Fusion.
After putting the cards away, Tenjo Hikari took out Flame Swordsman and Dark Flare Knight.
Now, they are Ultimate Flame Swordsman and Mirage Swordsman.
"Hahaha, Master, how did I do today?!" It said this way but was already laughing heartily.
"Quiet down, don't you see Master is thinking?"
Right after being taken out, Flame Sword first sought approval while Dark Flare interrupted from the sidelines.
Tenjo Hikari couldn't help but smile softly.
As spirits that have accompanied him the longest, with strength enhanced by Super Polymerization, later nourished by the Philosopher's Stone, they gradually acquired energy that should have been sufficient for evolution.
Yet, an issue has always troubled Tenjo Hikari.
That is, why can't they evolve.
Eventually, Tierra pointed at Dark Flare, explaining it didn't wish to evolve from a Fusion Monster into another type of Monster.
This mindset was undoubtedly "narrow" since Dark Flare has always known Tenjo Hikari doesn't care about a Monster's type—it's the process of Fusion that matters.
But it's inherently a Fusion Monster, therefore it is naturally more fond of this identity.
After Tierra pointed this out, it could no longer pretend, finally stepping forward boldly into new territory.
Meanwhile, Flame Sword was different.
Dark Flare could evolve but chose not to, whereas Flame Sword was eager to evolve but found himself unable to.
Although energy sufficient enough suggested it was possible according to Tierra's speculation, evolving just couldn't be achieved.
At that time, Tenjo Hikari thought perhaps Flame Sword needed to first create "Fighting Flame Dragon" to evolve, but while researching "Armityle the Chaos Phantasm," he suddenly thought—
Perhaps it's not like that—
What Flame Sword lacks is the capability to "shatter" itself, then recycle and purify.
Just like how Tenjo Hikari wanted to re-shatter Armityle the Chaos Phantasm and purify a "Hex-Sealed Fusion" from it, Flame Sword truly lacked the ability to split its power!
It couldn't achieve this!
After all, Flame Sword knows nothing about Alchemy nor how to transform.
Given such knowledge, even for Tenjo Hikari known to best "Purify" and "Sublimate" using Super Polymerization, it was very difficult.
In comparison to "Purification" and "Sublimation," his skills in "Shattering" and "Re-Creation" still required much study and practice.
But just recently—
A card appeared and disrupted Tenjo Hikari's research process—
Aleister the Invoker!
The appearance of this card not only suddenly elevated Tenjo Hikari's deck but more significantly, once he obtained Aleister, he could attempt many things he couldn't before using the "Emerald Book."
Pages in need of "verification," Tenjo Hikari could now directly examine.
After thoroughly revisiting everything, through Tenjo Hikari's independent research, he successfully extracted parts from Flame Sword's weapons as materials for Fighting Flame Dragon, and after Purification through Super Polymerization, Tenjo Hikari finally utilized his longstanding practice in Alchemy and Super Polymerization to "Sublimate" the Ultimate Flame Swordsman!
Although it seems complex, it actually wasn't difficult to execute, but without Aleister and the Emerald Book, Tenjo Hikari certainly couldn't have achieved it.
Based on such a trial, Tenjo Hikari finally grasped some Alchemical techniques for extracting Monsters from Fusion Monsters; however, although he figured out some groundwork, he still required assistance from Super Polymerization and has yet to achieve significant progress in extracting a Low-Level Monster from Armityle.
The duty is heavy and the journey is long!
Fortunately, no matter what, there is now a direction. By diligently advancing and experimenting along this path in the future, it will be enough.
Once all these things were made clear, Tenjo Hikari turned to look outside.
Outside, that pristine building stood there.
Saiou Takuma…
Tenjo Hikari took a deep breath.
Initially, he thought Hero, Destiny, Ed, and Judai and other things should be solved by two heroes entangled by destiny.
But things have changed!
Thinking about those students brainwashed by the Light Society, he pondered for a long time.
Though he did save many during the Dark World attack, the dangers cannot be ignored!
He can't allow him to act without restraint anymore!
