The essential cards for the Metalfoes Deck have been basically completed, and now Wan Rong can handle the rest himself, so Tenjo Hikari leisurely enjoys some free time.
Tenjo Hikari finished his work and then went on to study that special card.
A Coordinate Card. If possible, Tenjo Hikari actually wanted to put it directly into the Dimension Gate to get it transmitted over, but Tierra previously stopped him, advising against doing such dangerous things.
With the precedents of Ecole de Zone and the Branded Dimension, every new dimension now should have robots sent over first for a brief observation to confirm no unexpected dangers before departure.
She made a lot of sense, so Tenjo Hikari obediently listened.
The saying goes, "Once bitten by a snake, ten years afraid of the well rope." Tenjo Hikari didn't want to be inexplicably attacked by strange things again after traveling to a new dimension.
However, after the initial attempt, Tenjo Hikari discovered that he could not activate the Dimensional Coordinates.
Strange.
Tenjo Hikari fiddled with the card, comparing it with the data from the Dimension Gate, feeling a bit puzzled.
With coordinates, a Dimension Gate, energy, and no blockages, why can't it transmit?
He studied the card for a while, looking at the Big Dipper symbol on it, genuinely perplexed.
At other times, he might have set it aside to research other matters first, but "Drytron" might be crucial for Marufuji Shou and Marufuji Ryo, possibly an important tool to awaken Marufuji Ryo's memory.
Tenjo Hikari wasn't sure how Mitsuzawa Daichi lost his memory, but being with a Spirit and unable to recall anything, not even seeking companions from the Fusion Dimension, indicated that, in the spirits' view, Mitsuzawa Daichi's condition wasn't suitable for finding others.
It's likely some special shock or trauma that causes pain whenever he tries to remember, so it's better to just slow down and not rush it.
This makes sense.
Naturally, Marufuji Ryo's condition may be quite similar to Mitsuzawa Daichi's, and merely trying to awaken his memory might be problematic; it might be better to "evoke" the memory from another angle.
Moreover, since it's a request from Marufuji Ryo's own brother, Tenjo Hikari is certainly willing to support it.
Of course, part of it is also that Tenjo Hikari is willing to trust Marufuji Shou because Marufuji Shou's behavior has always been trustworthy, so he is willing to give his trust.
Whatever it is, interactions and relationships between people are mutually reciprocal, mutually given; when one respects you, you also respect them, for a kind exchange.
Initially, Tenjo Hikari and Tierra also started from hostility, eventually getting along very well through increasing interactions.
After contemplating for a while, Tenjo Hikari suddenly thought of a possibility.
"Could it be... that one card isn't enough?"
"What do you mean?"
Tierra asked confusedly.
"One coordinate might not be enough," Tenjo Hikari gave an example, "like the Branded Dimension, where multiple dimensions overlap; reaching all through one coordinate; naturally, there could exist a single dimension requiring two different coordinates to reach."
That sounds a bit odd.
Tierra seemed puzzled.
Tenjo Hikari slightly pushed the table, his chair rolling to the side, then opened his card protection cabinet, taking out a card to show Tierra.
Ursarctic Drytron.
Tierra quickly glanced over it.
With one Ursarctic Big Dipper and one Drytron Alpha Thuban from your Hand Card or field banished, Special Summon one "Ultimate Flagship Ursatron" from the Extra Deck. If Ursarctic Polari or Drytron Alpha Thuban exist on the field, you can also banish one card needed from the Deck.
"Is it Polymerization?" Tierra inquired.
She didn't know what kind of Deck Drytron was, but since it was brought out by Tenjo Hikari, it was probably Polymerization.
As for the other cards, she had only seen the Polari once and wasn't familiar with them at all.
"Ursarctic Big Dipper and Drytron Alpha Thuban are Field Spells."
"Field Fusion?!" Tierra exclaimed in shock after hearing it.
Unexpectedly, such a thing exists.
Tenjo Hikari had never performed such a feat.
However, if that's the case, then Tenjo Hikari's hypothesis can be understood.
"If that's the case, can you actually calculate to deduce the coordinates of another card?" Tierra then said.
Tenjo Hikari nodded.
The card provided by Marufuji Shou resembled the data for their dimension's "Big Dipper."
And since "Ursarctic" appeared in this dimension, perhaps another coordinate data for this special dimension is the spatial data of this dimension's "Big Dipper."
These can be deduced through calculation.
Tierra nodded, patted her chest, and said directly, "Alright, then afterwards, let's shove the ugly stuff to the Synchro Dimension and perform a comprehensive calculation."
Tenjo Hikari nodded.
Calculating spatial data of the stars is a large project for both of them, something that can't be done by merely observing; using Qliphort tools for statistics and calculation is a more rational plan.
While planning to collect data with an astronomical telescope together with Tierra, a machine slowly emerged from the other side of the Dimension Gate, powered by energy.
It was the Assembler!
