Chapter 303: Decade; Rescue

Decade.

The destroyer of worlds. With the [Decadriver] and [Aurora Curtain] in hand, he was a terrifying opponent. The former supplied him of adaptable strength while the latter allowed him to travel worlds.

Acquiring the [Neo Decadriver] was something done through luck. It was one of the reasons why Shiro aimed for it after seeing his parallel self receive it. Still, he did not expect a synergistic effect to occur between the two.

[Set effect of [Neo Decadriver] and [Aurora Curtain] activated...]

[The EX-rank buff 'Traveler of Worlds' has been acquired.]

[Traveler of Worlds]

Details: The characteristic of one person who could not return to his home. It grants immunity towards will interference, an adaptable body, and the power to become an immortal through peoples' beliefs. As long as a single thing remembers the wielder, they could be revived.

"What an effect."

While he is already a creator that could invalidate a wills' interference, having immunity towards it is commendable. If the time comes he gets injured, he could save his power. Moreover, the final effect is what surprised him the most.

"A Creator."

It is something one could get as a Creator. The ability to survive if someone remembers your existence. It is for this reason that many people could not believe his self-orchestrated demise back then. If creators are already hard to kill, Beyond creators are more so. The difficulty of removing their existence varies, too.

If a mortal had this, they could simply be invincible towards most enemies.

"Decade... Interesting."

Shiro took it out with the mindset of trying, but never had he thought he will receive something like this.

"I'm getting sidelined. I need to save the little girl first."

Rosmontis.

The feline girl whom he rescued in his timeline when he received a mission to destroy Loken Watertank. She was the result of two people merging into one—granting her unparalleled arts talent. As of now, she is a part of his company—the ones that are being taught, to be exact.

He opened several schools with his company's name. It is a plan to get more talented people from the infected side. It is also resulted by his will to change the fate of the discriminated ones. They reminded him of his past, the demon race whom he belonged to.

"I didn't see much from the moon. I could still fix this, anyways."

Moments later, he found himself standing on top of a roof. Sounds of screams and gunshots littered all over the place. His sight caught some strange creatures.

'Those are seaborn?'

They have a strange anatomy. Their hides made it difficult for blades and bullets to penetrate. Their tentacles are their versatile weapon for harvesting lives. Moreover, some of them could assimilate another lifeform by eating them. It is the reason why they could destroy Terra's civilization.

Once the higher-ups' bodies are taken over, they'll have total control over a country's countermeasures. They could spread misinformation, disrupt an order, fool their allies, and so on. This is the zerg horror everyone on Earth is scared of.

[Kamen Ride—]

Shiro pulled one of the belt's sides, activating its transformation sequence. Like in his memory, he drew a thin card from the [Ride Booker]. He examined it for a bit and confirmed it is the one he's looking for.

After restricting his physical prowess, he transformed.

[—D-d-decade!]

Suddenly, his vision turned gray. At this moment, he saw ten afterimages converging into him. As it happened, color returned to the world. The combat suit he is wearing gained a magenda color.

'Similar to the [Tail Gear], yet it is different.'

For once, Decade did not offer overwhelming strength. This base form simply provides some boost in physical stats. At most, it could be compared to several times an average human's power.

'I see.'

He pulled out the [Ride Booker] which turned into a gun. He selected a golden card from it before inserting it into the driver.

[Attack Ride—]

[—Blast!]

Boom-!

Boom-!

Boom-!

The surrounding Seaborns immediately exploded. Despite not having any combustible materials, the explosion happened naturally.

"Huh?"

"What..?"

"Arts..?"

The civilians did not receive any damage, either.

Wordlessly, he blasted the Seaborns he came across. Some tried to attack him with their tentacles, only to fail as he dodged.

[Attack Ride—]

[—Illusion!]

Shiro's figure split into three. Each of them held the gun as they easily cleaned their enemies.

[Attack Ride—]

[—Slash!]

The gun unfolded into a portable sword. The other two figures did the same before they swung it towards their enemies.

Boom-!

Boom-!

Boom-!

Afterimages are left on the swords' path. The enemies they have contacted exploded as well, defying the known physics of this world.

'There are too many enemies.'

In this experiment, he did not use the sheer power of a creator—he is nothing but an ordinary mortal. This is what made [Decade] shocking. A mere mortal could attain the ranks of a god, just like [Tail Gear]. Each of his attacks has the 'absoluteness' which ensures the attacks hit and damage the opponent.

It didn't matter whether the opponent is a god or mortal. They would all be affected the same. A slash would be fatal for a god as much as it was fatal to mortals. This is the horrifying [Absolute] aspect of [Decade].

[Kamen Ride—]

His illusions merged into his real body once more. He picked a card from the booker before inserting it.

[Kabuto!]

His vision turned gray. He could see himself change into another Rider. When the process was finished, he found himself on a beetle-looking combat suit.

"Time to sweep up everything."

[Attack Ride—]

Shiro's booker turned into a dagger. It is a black-gold dagger with a simplistic design.

[—Clock up!]

At this moment, time slowed down drastically. It is vastly more powerful than his [Time Accel]. He could see the trajectories of the air around them. He swung the dagger at them as they floated slowly midair.

By the time everything returned to normal, an entire street is suffocated by a huge explosion. Strangely, it did not harm anyone else. While confusion grew amongst the people, Shiro proceeded to clean up the entire city.

[Attack Ride: Charging Kick!] (Kamen Rider OOO)

[Form Ride: Fire!] (Kamen Rider Wizard)

[Kamen Ride: Build!] (Kamen Rider Build)

...

Shiro experimented with the powers it held. Through it, he settled most of the enemies inside the city. Still, there are a lot of Seaborns outside. What he did was to momentarily settle the matter.

When he exited his [Decade Form], the card flew upwards from the driver before he caught it.

"Decade. Another ace for my contingencies." Shiro muttered. "This is more reassuring."

When he placed the [Neo Decadriver] inside his storage, his buff did not disappear.

His silver pupils scanned the surroundings and grasp the structures around him. Outside the city, it was swarming with thousands of Seaborn in varying types. There are the smaller ones, but there are also human-like Seaborns. They possessed more power than the rest.

Suddenly, rays of moonlight shone on an area. Moments later, the Seaborns began turning into gray ashes. The cleansing attribute of the [Moon] made it possible to [Cleanse] its target. It is the total opposite of the [Moon]'s previous attribute under the outer god—corruption.

Shiro stepped on the cleansed area.

"Who are you?"

One of the Seaborns asked.

"It's quite surprising." Shiro replied. "You're civilized?"

"Your words are pretty confusing. However, we are of single entity."

"A hive mind?"

Seaborns consider themselves as a single entity. All of their decisions are made to better everyone's lives. As for those who aren't a part of them... they just have to devour them for them to be considered as a part of "everyone".

In a sense, they are similar to "BETA". They are a terrifying hive mind that could pose a threat to habitable planets.

"I am wondering. Why did you become hostile with the surface?"

"Hostile? What do you mean?"

"This was all to be one with him."

"It is to include everyone with us."

Shiro has a feeling that Skadi is the primary reason why everything happened.

"It doesn't matter. You are threatening the world itself due to your innocence. Perhaps, it is your flaw as an individual mind."

"What do you mean?"

"You don't have feelings. Instead of being an 'individual', you are the type to think of the 'greater good'."

Strangely, the nearby Seaborns felt something similar to irritation.

"We don't understand."

Yet, their feelings hint that they are adverse to his statement.

"Maybe we could understand after you become one with us."

"With some zergs? I have to decline."

The radius of his moonlight grew in size. Seaborns tried to approach him, only to fail. His domain is absolute enough for him to create a path in the battlefield littered with Seaborns. The wet ground caused by a tsunami did not help, either. Their strengths should have been the same as in the sea, but why couldn't they approach him?

"Gun—" He was about to summon forth his Exia. "I nearly forgot. It's still chilling on another world. Then..."

He located the place where Rosmontis and the others are located.

"Let's rewrite reality a bit."

Hum-!

A wave emerged with Shiro as the center, obliterating his enemies instantly. The physical bodies of the Seaborns did not survive for a few seconds. Beyond the pathway lit up by moonlight, there was nothing but ashes. In fact, every single Seaborns present around Colombia turned into pile of ashes.

Shiro passed through the aurora curtain. A second later, he found himself in front of a driving van. Seaborn corpses are littered in its surroundings. He also saw three giant broadswords embedded into the ground. The remaining one is still floating above the van.

His location is roughly 200 kilometers away from the city. Shiro controlled his power to not extend beyond the city's periphery. Still, his senses caught everything happening here.

"What—"

Sharp immediately pressed the brake and drifted to his right. This made it so that Shiro was barely run over by them.

Knock-!

Knock-!

Sharp decided to open the windows—

"On the orders of Dame Kal'tsit, I am to escort you to safety."

—only to encounter the surprising words of the man.

*****

Fact #105: Ironically, Seaborns are a product of an ancient civilization in Terra. They sought treatments in regards to Oripathy and Originum, and one of the ideas actualized by them are the creation of Seaborns. They are supposed to consume originum for energy and are immune to its downsides. In a sense, they are made to be the "janitor fish" of this world. Though, they are not helping in the canon as of now...

PS: We'll be having a fun fact for the said ancient civilization tomorrow. The info revealed from there are something already up on the CN servers (to be specific, Doctor visiting a "mass cryo chamber" (Sarcophaguses) that malfunctioned).
