Ultraman cubs begin to wreak havoc.

From above, Subaru watched as Ota Yuuka, after completing the installation, skipped and hopped to pull the switch. Amidst everyone's tense expressions, all the indicator lights above Jugglus Juggler's head lit up, and Jugglus Juggler himself involuntarily tensed up...

Then....

There is no more.

"How could this be... Why isn't my brainwave bio-neural transmission trigger working?!"

Seeing this, Yuka Ota pressed her hands to her head, unable to accept it, and let out a cute, pitiful cry.

"Hey, hey, hey, that's not what you called this just now. You said it was a relaxation device!"

Jugglus yelled as he took off his helmet and casually placed it on the table. To be honest, he was really worried about whether he, as an alien, could withstand Yuuka's recklessness. After all, he had witnessed firsthand how 'crazy' this girl could be.

Just then...

"Gah!"

Jugglus suddenly slumped onto the table, motionless. This action startled everyone present. Ota Yuka gently nudged her captain, complaining, "..."

"Okay, okay, Captain, I was wrong, I won't use you as an experiment again, please don't..."

Huh?! X3

Before Ota Yuka could finish speaking, the three of them saw their captain actually about to fall under the table. In that instant, they realized something. Ota Yuka, who was closest to Jugglus, almost instinctively picked him up and ran to the medical room—no, to her laboratory. As a biological expert, her equipment would be able to quickly determine which part of their captain's body was malfunctioning.

But before Ota Yuka could run more than a few steps, Nakajima Yoko had already taken Jugglus Juggler and was carrying it on her own back. Compared to physical strength, Nakajima Yoko was definitely the best in the team!

As for Natsukawa Haruki, the man closest to the door, he immediately darted out and headed straight for the medical room to prepare for docking with the biological laboratory.

It has to be said that this team has great teamwork.

As for Jugglus Juggler...

Looking at the pure white light in front of him, Jugglus immediately understood that this energy projection had returned from its fight and crashed into his body, knocking him unconscious.

Oh dear, how could this happen? I'm so angry! Really, these little guys outside are going to be terrified.

"Captain Hebikura, wake up!!!"

"Okay, okay, I'll do it now... um?!"

Hearing the plaintive cries, Jugglus Juggler responded helplessly, like an old father. Then, immediately, he sensed something was wrong; that voice...

Subaru! You've come!

Although Jugglus Juggler appeared to be asking a question, his tone was quite certain. Subaru chuckled, dispelling his pure white light, and appeared before Jugglus Juggler, smiling as he said:

"Ah, I'm here, Jugglus-senpai. Wow, I didn't expect Jugglus-senpai to be having so much fun role-playing here. Gai-senpai was getting anxious and upset because he couldn't find you."

"Hmph, Kai... well, that's just how he is, a busybody, serves him right for getting anxious and upset."

Yes, yes, you're right, Jugglus-senpai, but you can't suppress your smile before saying that.

Gen Subaru nodded obediently, but inwardly he was thinking this to himself. Then, Gen Subaru composed himself and said seriously:

"Senior Jugglus, do you have any leads regarding the attack you just encountered?"

"Huh? Oh, that wasn't an attack. It was just a little girl being mischievous. I was just playing along because I was bored..."

"Senior Jugglus, please wake up."

Clearly, Jugglus Juggler didn't understand what Subaru was saying, and the child could only helplessly add:

"An enemy attack that triggers the pure white light and can elicit such a reaction from the pure white light can generally only be described as an attack from a primordial being."

"I didn't notice it at all."

When the topic of green creations came up, Jugglus Juggler immediately became serious. He thought for a moment, then shook his head and said softly:

"I've never encountered that greenish-blue ghostly thing."

"Then it seems... it's being done in the shadows."

Subaru pondered for a moment, then looked at Jugglus Juggler and said:

"In that case, I won't stay any longer. This Primal Creation seems to be making quite a big move and has a grand scheme. I need to go and see what exactly is causing this trouble. By the way, Senior Jugglus Juggler, do you know that there is an Ultra Warrior hidden inside Haruki Natsukawa's body?"

"Ah... Ah?!"

Apparently he doesn't know.

Jugglus's eyes widened, and he said incredulously:

"Impossible, right? There's an Ultraman inside Haruki? No way, absolutely impossible. If there were, how could I possibly be with him every day... Am I just getting old?"

As he spoke, Jugglus began to lose confidence. Subaru was always reliable and incapable of making mistakes; it could only be himself...

"That Ultra Warrior is still asleep. He must have been injured in some battle before, which is why he is so unresponsive. Senior Jugglus, you don't need to worry about it."

Gen Subaru explained, then looked outside and said softly:

"Long time no see! I should have had some fun with Senior Jugglus, but since we've gotten involved with Primal Creatures, let me deal with this wretched thing first, then I can play with Senior Jugglus. See you later, bye-bye~~~"

After saying that, Subaru left Jugglus Juggler's body without any hesitation.

As Subaru detached from the pure white energy within Jugglus Juggler's body, his consciousness returned directly to Earth in TLT. Subaru immediately grabbed the replication engine and entered the River of Time, realizing that his opponent was hiding within time itself.

Gen Subaru acted quickly, and soon he noticed something was wrong. In the river of time, he discovered impurities. Outside the ever-flowing, straight timeline, there were extra, free-floating time bubbles, something that could never have been generated naturally.

Let me go in and take a look.

Subaru's idea was simple: only by getting involved himself could he find clues to the mastermind in the shortest amount of time. But this time...

The round window, twelve centimeters in diameter, is inlaid with a reinforced plastic called isobutylene. All that can be seen from there is an endless world of darkness. The field of vision is at most ten meters.

This "Dragon Palace" is a 7,500-meter-class submersible research vessel, but this survey was planned to dive to a depth of about 1,000 meters. Even so, at this depth, a force of 100 kilograms was applied to every square centimeter.

Forty minutes after separating from the mother ship at sea, the Co-Pilot (First Officer) announced:

"We'll reach our destination in five minutes."

The pilot (captain) slowed the descent.

Gen Subaru stood on the ship, staring intently at the dark shadows illuminated by the searchlight. This was the first thing Gen Subaru saw after entering this time bubble, and he felt the hairs on his body stand on end and tremble uncontrollably.

So that's how it is. Did I directly replace one of the entities in this time bubble?

And it's a very special substitution because this is about the 'past,' so I will be able to experience everything the person involved felt at that point in time.

Interesting, interesting... could this be a trap?

"It must be cold."

"This is what the captain said to Subaru at the window," the captain said. At the same time, a piece of information appeared in Subaru's mind—

The three of us were inside a sphere with a 73-centimeter-thick titanium alloy pressure hull. Only the captain was seated in a chair; the first mate and I sat directly on the floor.

"It's great to wear the training clothes underneath, just like I heard."

"This indoor clothing is convenient for movement, but it's a bit thin."

The primary purpose of this deep-sea submarine inner garment, made from quilted special fibers, is to provide warmth.

But was the trembling that Gen Subaru was feeling just due to the low indoor temperature? This isn't right...

啵—

With a strange sound, the white seabed appeared before my eyes. The searchlight's beam was narrow, but I could see that the seabed was a gentle slope.

It should be in this area.

The first mate looked at the instruments and spoke to Gen Subaru, who then felt his body become uncontrollable, constantly looking out the window.

"Mr. Katsumi, can you see this?"

"No....."

"So, as planned, we'll head north along the slope at this depth."

This is the starting point of the wilderness at the foot of the underwater mountain range. The mountain, once an active volcano, is now silent, sleeping soundly in the ocean depths where light cannot reach.

Long-legged arthropods move slowly across the white sand.

The person Minamoto Subaru replaced was originally tasked with observing these deep-sea creatures, which is why he took up this "Dragon Palace" position. However...

"This place is...very strange."

The first mate suddenly shouted.

"what's wrong?"

"There are dents everywhere."

Is it a chimney?

A chimney, as its name suggests, refers to the opening in an underwater volcano that eventually emits hot water and smoke, not the chimney of a tall tower.

"No, that's not it. There really are rows of very large holes. Very large, at least thirty meters in diameter."

Although it cannot be confirmed from the window, the monitor scanning the seabed surface must be visible.

Is it the remains of a crater?

"No... I feel like there's a pattern..."

We cannot stay here any longer.

Yuan Mao felt that voice coming from the depths of his heart; it was the fear in the heart of the person being replaced.
