This Monster used to be one of Tenjo Hikari's favorites. Back when he played with a full Deck but limited himself to one copy of each Card, he especially liked adding this one in.
However, they weren't here to watch some Cosmos war. Tenjo Hikari pressed the comms, trying to contact those factions.
Even though the fighting looked heated, it wasn't a Duel after all, so he should still be able to get through to them—
The next second, Tenjo Hikari saw all those factions abruptly cease fire one after another. They slowly adjusted their formations, gathering together into several units.
The three of them exchanged looks, and right after that, another voice came through the broadcast.
It was a mechanical voice.
"An invitation to a Duel Ceremony is indeed something a Warrior cannot refuse—however, humans, you trespassed into our Training Ground without permission, hid yourselves, lay in wait. That is not something that can be settled so easily now."
Eh?
The three of them glanced at each other.
Lurking? The hell?
"Oh—Tenjo Hikari, there seem to be other humans over there as well."
????
Huh?
The three of them were a bit dumbfounded.
Someone actually beat them to the punch like this?!
Tierra tapped a few buttons, and they saw a spaceship that looked just like a Pyramid slowly fly out from behind the Planet's shadowed edge.
Tenjo Hikari's pupils shrank.
It was actually—
The Emperor's Key?
Another voice came from the broadcast, requesting that they dock at the Space Port so that their "Great Leader" could personally conduct an evaluation.
"Looks like this is a Dimension similar to a Mountain, Little Hikari." Seeing the situation, Fubuki felt a sense of déjà vu and spoke to Tenjo Hikari.
Tenjo Hikari nodded, thinking that was indeed the case.
Anyway, even if they'd kind of been "friendly fired" on.
He was also very curious why the Emperor's Key would be here. So he didn't show much resistance and let Tierra control the ship, slowly docking at the "harbor"—the Ursarctic Big Dipper.
After docking with the ship, the three of them disembarked slowly. Marufuji Shou was nervous at first, afraid he'd suddenly blow up and die, but once he landed, he found that although things felt strange, he wasn't having any trouble breathing.
On the Big Dipper there were several dragon-type robots, watching Tenjo Hikari and the others cautiously, ready to spring into action at any moment.
This was a Training Ground.
But not just any Training Ground.
It was the Training Ground—or rather, the simulation arena—for a whole bunch of "Cosmos battleship-type" Spirits.
Every so often, these battleship-system Spirits would hold a big tournament, fighting each other. Then, based on their records, they'd sort out different brackets, opponents, and who went first, and eventually decide on a new Champion to receive the Great Leader's legacy.
In short, this was an extremely important Training Ground for these Spirits.
So the ones running simulations and sparring here were all the "most elite of the new generation" from each race!
As a result, just moments ago, when Tenjo Hikari and the others suddenly appeared in this Cosmos, a damaged Laser Cannon had fired straight at them. These Spirits were just thinking about how to rescue the victims when they realized that aside from the kinetic impact, that machine didn't have a single scratch on it!
Granted, a Spirit's power and size weren't absolutely correlated, but the bigger the Spirit, the more energy it could store. And yet that kind of attack had hit this machine head‑on without causing the slightest damage—
At that moment, the superiors of these Spirits understood.
They had definitely run into some kind of super powerhouse.
Tierra followed Tenjo Hikari out, sweeping her gaze left and right, her eyes sparkling.
Oh—
This Mecha looks pretty good! Oh! That Mechanical Dragon actually has a nice design! Wow, what's that thing, a Dyson sphere? Oh, no, it's that kind of machine that remodels a habitable Planet. Not bad, they've got brains!
While she was openly gawking at those Spirits, the Spirits were just as cautiously dealing with Tierra.
As Tierra's power returned and life flowed back into her, the strength she never bothered to hide became more and more obvious. The stronger the Spirit, the more clearly it understood that this seemingly petite existence was absolutely not someone they could take on easily.
Mass, volume—looked at from a "scientific" angle, these things clearly defined power tiers. A Star System Level battleship was obviously more powerful than a Planet Level one. But if you started from the soul, from transcendent power, these Spirits could feel from the bottom of their hearts the terrifying pressure Tierra radiated.
If a being like this suddenly chose to strike, they would probably have to call the Great Leader here to save them.
On the other side, the Emperor's Key slowly docked next to the harbor. Marufuji Shou and Tenjouin Fubuki watched curiously as people came out from inside.
"Kids?" Tenjouin Fubuki frowned.
How could kids have ended up in such a dangerous Dimension?
A boy and a girl, both in casual clothes. The boy looked a bit exhausted, while the girl clung tightly to his side, clearly very nervous.
Floating beside them was a glowing being, hovering in the air. When this group saw Tenjo Hikari and the others, they quickly bowed and greeted them.
Lobster-head and the green-haired girl thanked them over and over, saying that if not for them, they didn't know how much longer they would've had to keep hiding.
Now, they could finally leave.
"You may not leave—" Not far away, a huge woman in red robes, holding a Magic Staff, slowly walked over.
Cosmo Queen.
"Eh!" Tsukumo Yuma jumped in fright.
Tenjouin Fubuki quickly turned around and said to her, "Cosmo Queen, these are humans who accidentally strayed into this Dimension. They did not intend to disrupt your training. Please give us a chance to let them leave this place, and forgive them for the crime of ignorance."
