As for the DD Dog—
It's a very convenient field-clearing card!
Without saying much else, if at this moment a bald head suddenly revives and appears in front of him to duel, just relying on this card, Tenjo Hikari can stop the Pendulum Commander.
Of course, the key point is...
These cards are in their completed state!
Tenjo Hikari stared at these cards, his eyes widening.
This...
Does it mean that at this moment, humanity is swinging towards other possible outcomes?
Oh!
It's reasonable!
Tenjo Hikari was enlightened.
Then—
Tenjo Hikari hastily searched through his card box and found that card.
"Wow!"
Tierra excitedly picked up that card.
Apoqliphort Towers!
This is good, directly born!
Indeed.
Since Pendulum Cards have been born, it was to be expected that the "materialism" attempted for Pendulum creation would have long been completed.
Including the thorough creation and completion of "Infernoid Onuncu" during the duel, Tierra's body has already fully recovered more than half.
Moments later, Tenjo Hikari put everything away.
Due to the death of Darkness, Mr. T also vanished, dissipating along with it.
However, this world still exists.
Or rather, this world has wholly become another "dimension" attached to their world Earth.
Moreover, unlike other dimensions, leaving here doesn't require rest or recovery, as entering the Spirit Dimension would, because Darkness has disappeared, making this world entirely another "Earth."
Although Tenjo Hikari and the others tried, finding buildings and trees here to be fake and unable to grow crops, only suitable for viewing, it remains "another world" for humans.
Simple exploration around the academy was done before they returned to reality.
In reality, everything seems unchanged, continuing as before, with classes going on as usual with only occasional strange occurrences.
For instance, some classmates who usually dislike Tenjo Hikari greet him inexplicably, and those who joke about Judai sleeping in class respond with laughter to Judai's greetings.
The reason is unknown, but in any case, Tenjo Hikari, already very popular, became even more popular, not just among classmates and friends, even strangers instinctively smile when seeing Tenjo Hikari.
After the incident ended, when shooting commercials for Fengguang Company, passersby would instinctively greet him, and even tough guys in dangerous areas wouldn't offend him.
Tierra said it might be because Tenjo Hikari and Yuki Judai truly became "human heroes," making humans feel naturally close to them.
Everyone feels this way, just as humans are mostly influenced by Darkness's power, even the powerful "Legendary Duelists" aren't exempt.
This kind of affinity merely makes people feel closer to Tenjo Hikari, but doesn't have a brainwashing effect; those who hate Tenjo Hikari will still hate him despite thinking he's handsome, unchanged.
Although there are very few people hating him in the world.
After the crisis was resolved, Tenjo Hikari felt daily life was genuinely joyful — studying, attending classes, eating, sleeping, playing games, and acing exams to make Manjome grit his teeth.
The professors' performances were gradually evaluated; aside from a few who were incompetent, the rest stood by the students during the "Darkness event," earning commendations and excellent evaluations.
Besides studying, Tenjo Hikari and friends explored the "Inner World" regularly.
For one thing, exploring this world requires very low energy; it could even be said it requires no energy. For another, there's a chance that subsequent events need handling there.
They remained curious if anything hidden awaits in this world and were cautious of any remaining Darkness remnants.
Initially, a streak of black light flashed across the sky; others didn't notice, but Ed observed closely. He speculated there might be Darkness remnants here, thus spending uninterested class days directly exploring the Inner World.
Additionally, being adept at boating, surfing, and flying planes, Ed's exploration was very successful, leading him to several discoveries.
First, there is indeed a "darkness" remnant; he discussed with Tenjo Hikari and concluded it should be [Tragoedia]— a card used by Darkness.
How it survived Darkness's death and Mr. T's disappearance is unknown, but it indeed escaped, hiding in this world, still attempting to gather Darkness's remnants.
That's right—
Darkness's "remnants."
This is the second issue Ed discovered.
Although Darkness disappeared and Mr. T closely followed, Darkness's influence wasn't limited to these Mr. Ts.
In the "Inner World," many spirits exist!
Due to the presence of Red Light, Spirit World started collapsing; several spirit homelands were shattered, driving them to seek shelter under Darkness's command.
Not all spirits acted as "cannon fodder," being sent by Darkness to pressure Duel Academy; these spirits hid in this world, avoiding invading the Human World.
Among them, there are many spirits forming part of Darkness's Deck!
For example, "Soul" Monsters, "Gemini" Monsters - many such entities exist in this dimension!
Cards used by Darkness have now ripped apart and fallen into this world.
These cards turn into ownerless cards, only following those who earn their approval, much like Spirits from the Spirit Dimension.
In other words...
The "Inner World" is essentially a vast "opportunity" world!
It's vast enough!
Can accommodate Earth's human population!
It's rich enough, housing numerous spirits!
These spirits, both strong and weak, weren't dispatched by Darkness; the strong ones directly joined the deck— it joined Darkness's deck, exemplifying their strength!
Even if they haven't appeared in the duel, once acquired by a duelist, they can become the deck's ace card.
Such cards could be hidden all over this world!
Regarding this matter, Tenjo Hikari and friends feel both danger and excitement.
Danger, of course, arises from possibly many spirits hating humans.
Excitement, however, stems from this entire Inner World being incomparable wealth for duelists!
Daily study-focused individuals like Jim and O'Brien, either being an archaeologist or a mercenary indifferent to academics, spend days steeped in the Inner World, exploring and attempting to collect powerful cards.
As for Ed, committed to tracking down and eliminating "Tragoedia," he even spends consecutive days in this world.
Manjome thinks the future here has significant potential for development, possibly replacing Tenjo Hikari's "Dimension Gate" left to the Fusion Department, saving him maintenance effort; it might also hold considerable commercial value, hence he assists in data collection and organizing intelligence, aiming to help friends plan routes challenge in the Inner World.
Of course.
For Tenjo Hikari, the most crucial intelligence may not be these.
Rather, under Ed's investigation, they discovered that Darkness's world might connect to numerous Spirit Dimensions linked with "apocalypse" or "calamity"!
These are dimensions reachable by merely "walking," considered direct access, with no extra energy required.
Furthermore, within this Inner World, regions exposed to "Red Light" exist— those areas are now entirely red!
Even Tierra can collect some left-over "extinction" energy from Darkness here, partly providing more "Spirit Power" to the "Infernoid" bodies, partly aiding Tenjo Hikari in card creation.
Summarizing, beyond Darkness's disappearance and human evolution, the existence of this world itself signifies wealth for humanity!
And such wealth, Tenjo Hikari and friends can freely explore!
