Harvesting the Kadoya Tsukasa Sub-Template

"Obtained Kamen Rider Decade Ridewatch!"
The black and light pink Ridewatch, unlike other Ridewatches in its design, had a slot running down its right side.
Zi-O held the Ridewatch in his hand, a triumphant smile gracing his lips. This was truly an unexpected delight.

"Your Majesty the Demon King!"
Woz could no longer wait, his gaze fixed on Zi-O.

"Let us celebrate grandly, Woz."
This was the first time His Majesty the Demon King had requested a celebration! He must perform exceptionally well!
Woz transformed his inner excitement into a resounding cheer.

"Rejoice! He is the one who gathers the power of all Riders and Sentai into one body, transcending time, understanding past and future, the King of Time! Now, he has obtained the power of Kamen Rider Cross-Z and Decade, taking a great step forward on the path to becoming King!"

"Woz, you've been up all night. You may withdraw for now." Zi-O gently stroked the Decade Ridewatch in his hand, speaking softly.
Woz felt an immense reluctance in his heart; His Majesty the Demon King still had a Sub-Template yet to be drawn!
But it was His Majesty the Demon King's command. "Your subordinate obeys." Woz took two steps back, adjusted his scarf, and vanished from the spot.

"The Destroyer of Worlds?"
This was one of the countless nicknames of this Rider. Others included "The existence that destroys all Riders," "The destroyer of all things," "Kadoya Tsukasa," "The Demon"...
The classic line that Zi-O had uttered many times, "I'm just a passing-through Kamen Rider, remember that!" was this very Rider's exclusive catchphrase.
And ordinary enemies never remembered this line; don't ask why.

On the other hand, this Rider's ability was actually identical to Zi-O's: one collected Ridewatches, the other collected Rider Cards.
By utilizing Rider Cards, he could transform into the corresponding Kamen Rider and use their respective skills.
He could also use cards to transform other Riders into all sorts of strange props. Of course, the player eventually got played back. In the movie, he was once transformed into a giant Driver by Kamen Rider Diend.
It was also worth mentioning his flashy finishing move sound, which was incredibly catchy and brainwashing. Moreover, it ushered in the era of Kamen Rider DJ sounds, causing the sounds of subsequent Riders to deviate in all sorts of directions.

"Before I transmigrated, the Decade in Zi-O's belt had turned pink, capable of using the power of the Neo-Heisei Riders. I wonder if the Complete Form will change."
In the old ten years, Decade's Complete Form used the K-Touch, gathering the power of 9 Kamen Riders.
The method of gathering was to string their portraits... no, their Rider Cards into a chain hung across his chest, while his own image had to be placed on his forehead.
It was dubbed the Ancestral Form!
He could, by touching the Rider Cards on his body, summon corresponding Rider clones as physical entities to fight alongside him.

And when Zi-O used this Ridewatch, after watching its spin-off with Zi-O, he was truly disgusted.
The Neo Decade Complete 21 form... Alas, words failed him.
Zi-O did not throw the Decade Ridewatch into the system space but held it in his hand, simultaneously issuing an internal command.
A semi-transparent virtual plane appeared before him, but at this moment, the plane was enveloped in a white light, its content obscured.

"It seems that after hitting one jackpot, the probability of getting good items is very high now. I must strike while the iron is hot."
Templates were different from Ridewatches. Ridewatches were external objects before upgrading to meet the demon, while Templates directly fused with oneself.
A good Template could significantly enhance Zi-O's inherent strength.
Zi-O took a deep breath, looked at the plane before him, and after calming down, opened his mouth and said, "Draw a Sub-Template!"

The white light on the panel vibrated, and a second later, it collapsed, revealing the figure on the panel.
A blond man, wearing a red shirt, black suit, and a light pink camera hanging on his chest.
"Draw complete... Obtained Kadoya Tsukasa Sub-Template!"
The system's voice sounded simultaneously.
Zi-O was stunned, looking at the Decade Ridewatch in his hand. You have this function too?

"Wang Xiao... Kadoya Tsukasa?"
"Do you wish to fuse the Kadoya Tsukasa Template?"
"Fuse!"
"Sub-Template fusion initiated!"
Following Zi-O's command, the plane before him transformed into light pink specks of light that merged into his body.
The Kadoya Tsukasa Template's fusion rate began to skyrocket, so fast that even the Main Template would shed tears watching.

"System, what's going on?"
"The Host's current physique has surpassed the base form of this Template."
While Zi-O was communicating with the system, the fusion rate had already surpassed the Complete Form.
Zi-O immediately understood, clenching his fists. Indeed, there was no increase in strength.
The system calculated the maximum value, not the cumulative value.
With the 24% data that Zi-O had fused in his current Zi-O II stage, it had indeed far exceeded Decade's forms.

When the Template fusion was complete, Zi-O gained several new abilities.
Some strange abilities included: being rejected by the world, thus able to take bizarre photos; being assigned a new identity in each new world; knowing how to speak Gurongi...
And most importantly, the Dimensional Wall ability. Although he could use it after obtaining the Decade Ridewatch, it required transformation. Now, his physical body could also use it.
After all, this move was something Tsukasa was born with; only later, during his major overhaul, was the method of creating Dimensional Walls stuck onto him.

Another more important point was that because the Sub-Template fused, the Main Template also underwent some changes.
Zi-O gained an ability similar to Decade Slash, capable of transforming defeated Riders/Sentai into Rider Cards. The only difference this time was that they weren't turned into cards, but molded into Ridewatches.

"Not bad, not bad, this Ridewatch and this Template are both things I need! Next, it's time to try this!"
Zi-O's index finger slightly hooked, and a gray-white ripple wall appeared beside him. Zi-O waved his hand again, and the wall slowly retracted.

"So this is what it feels like." Zi-O felt a familiar sensation after performing it once, and he also found that the physical exertion was not significant.
The Dimensional Wall could be used to travel through universes, through space, and even through time was not a problem!

"It's really convenient!"
Whether it was the Den-O system Ridewatch, or Zi-O's current Time Mazine, both could traverse time and space, but until now, they required the aid of artifacts.
How could that be as convenient and cool as the Dimensional Wall!
Now with this power, he could begin preparing to go to the next world.
But in the Gaoranger world, Zi-O still had one promise to fulfill.
