The 5th ST is a cosmic structure located on the far side of the moon.

Its exterior resembles an amusement park, but its interior functions as a combat coliseum.

Musashi Arena is connected to this 5th ST, enabling observation, recording, and viewing of battles.

MAI

The 5th Station is a gigantic structure located on the far side of the moon.

Kaname🦁

Starting on the far side of the moon, huh... the scale is already absurd 😂

🦁

MAI

Its exterior is disguised as an amusement park, but inside it's a combat coliseum.

Kaname🦁

It's the kind of facility that would make normal tourists want to leave in 3 seconds 😌

🦁

MAI

Nuclear weapons, called the "Ultimate System," have been brought to the site.

Kaname🦁

It's beyond an amusement park; it's a one-strike-and-you're-out situation 💣

🦁

MAI

Then Yamato Nadeshiko, affiliated with public security, rushed in. She reached it fastest via MPM Shuttle.

Kaname🦁

Normal pursuit is impossible. The concept of traffic laws no longer exists 😂

🦁

Musashi Arena uses its own observation system.

• Real-time battle synchronization
• High-precision video transfer
• Accumulation and playback of battle logs

This makes it possible to monitor battles in space from real space.

*Detailed specifications are not public.

MAI

The true nature of 5th ST is a giant casino structure.

Kaname🦁

The difference between an amusement park and a casino is insane lol

🦁

MAI

Nadeshiko destroyed and neutralized X's nuclear weapons with a kick.

Kaname🦁

Normally, this would be a special forces operation, but this time it was handled with leg power 😌

🦁

MAI

Having lost its nuclear weapons, X lost the will to fight and withdrew from the battlefield.

Kaname🦁

The moment they lost strategic weapons, the battle situation completely collapsed 😏

🦁

MAI

By the way, what exactly is G doing at the casino on the 5th Station?

Kaname🦁

According to current information, G is believed to be distributing a large quantity of jewelry to the market as casino prizes 😌

🦁

MAI

So it's a distribution system that utilizes an "amusement facility"?

Kaname🦁

Exactly. It's a structure that rapidly disseminates goods at low prices without going through normal distribution channels 😏

🦁

MAI

And X was trying to seize that interest from G...?

Kaname🦁

That's highly likely 😌 The 5th Station was probably not just a casino, but a "massive distribution hub."

🦁

MAI

I see... I'm starting to understand why the battlefield shifted from "space" to the "market."

Kaname🦁

And there are reports that price collapse has already occurred on site 😂

🦁

In the Episode 3 commercial video, partial reactions of an unidentified high-speed movement phenomenon called "Aura Ball" were confirmed.

Currently, the Musashi Arena Observation Station is analyzing its relation to Episode 5.

MAI

At the end of the Episode 3 commercial, we confirmed a high-energy movement reaction. It doesn't match normal maneuvering patterns.

Kaname🦁

So, it's "that" 😂 We don't have all the details yet, but it's starting to be called "Aura Ball" on site.

🦁

MAI

Continuous intermittent reactions are still ongoing around the 5th Station.

Kaname🦁

There's a possibility of official observation in Episode 5 😌

🦁

Moon-side Casino Coliseum. This is not a "suppression operation" but an **observation record of an unknown event (UNKNOWN occurrence)**.

Chief W

The site is sealed. But... I don't think this is the "end."

🚓

MAI (News)

This is the observation log. A structural anomaly of G forces has been detected. However, the event has not fully concluded.

Kaname🦁 (Expert)

This isn't the "end of combat"; it's the "phase of collapse of the domination structure." The surface organization has broken down, but there's still an "unknown will" remaining.

🦁

MAI (News)

...Abnormal behavior confirmed for X. Disarmament has not been achieved.

Kaname🦁 (Expert)

In other words, what's important here isn't "who won." It's that "an out-of-bounds entity is still active."

🦁

SFX

——BANG!!

💥

MAI (News)

Gunshot detected. X fired at Lady Nadeshiko! Whether she was hit is unconfirmed. The target's response is ongoing.

Kaname🦁 (Expert)

The important thing here is that "there is no result." In a normal battle, this would be the decisive moment, but this time it has entered an "unobservable realm."

🦁

MAI (News)

...UNKNOWN reaction detected. The record ends here.

Kaname🦁 (Expert)

In other words, this isn't a "record of victory or defeat." It's a "log of the moment an unknown intervention occurred."

🦁

Episode 3: Gunshot──Observation complete.
Result is unconfirmed.
However, only UNKNOWN reactions were recorded.

Re-analysis of 5th ST observation log. This is not a "follow-up to the shooting incident" but a record of spatial anomaly analysis after the UNKNOWN reaction occurred.

MAI (News)

Re-analysis of the Episode 4 observation log is complete. We confirmed an abnormal coordinate change immediately before the UNKNOWN reaction occurred.

Kaname🦁 (Expert)

You noticed. This anomaly isn't a gunshot. It's occurring in space itself.

🦁

MAI (News)

In the footage just before the shot, the moon is behind Lady Nadeshiko. However, in the record after the shot, it has moved to the front.

Kaname🦁 (Expert)

Normally, this would be inexplicable. But the moon didn't move. What changed was the observed space.

🦁

MAI (News)

So there's a possibility that a spatial coordinate anomaly occurred inside the 5th ST.

Kaname🦁 (Expert)

Exactly. And that timing perfectly matches the time the UNKNOWN reaction occurred.

🦁

MAI (News)

The unregistered signal confirmed at the end of the video. Its name is... YUI.

Kaname🦁 (Expert)

We can't confirm yet. But the 5th ST's observation record has been altered from this moment on.

🦁

MAI (News)

YUI... That name sounds somewhat nostalgic.

KANAME🦁 (Expert)

Perhaps. But now is not the time.

🦁

Episode 4: YUI Appears ── Analysis complete.
UNKNOWN reaction continues.
A correlation with the 5th ST spatial anomaly is suspected.

Re-analysis of 5th ST observation logs. This is an analysis record of the "X Fleet Appearance Incident" and the unidentified energy phenomenon "AURA SPHERE".

MAI (Reporter)

X, who escaped from the 5th ST, boarded the flagship waiting at the outer dock. Immediately after, large-scale fleet operations began.

KANAME🦁 (Expert)

It's interesting, isn't it? They were running away in the 5th ST, but as soon as they boarded the flagship, they suddenly became aggressive. It's very transparent.

🦁

MAI (Reporter)

After that, the fleet began concentrated fire on a single MPM shuttle. The balance of power was extremely uneven.

KANAME🦁 (Expert)

A fleet against a single shuttle. It's more intimidation than strategy. Well, those who are cornered tend to act that way.

🦁

MAI (Reporter)

And at the same time, an unidentified energy reaction was detected from Lady Yamato Nadeshiko. The identification code is "AURA SPHERE".

KANAME🦁 (Expert)

It's finally here. The Aura Sphere. It's the highest output ever recorded in the 5th ST.

🦁

MAI (Reporter)

According to the analysis team's report, the unit deploying the Aura Sphere exhibits maneuvering capabilities far exceeding its normal state.

KANAME🦁 (Expert)

Simply put, it's maximum speed. A propulsion state to freely navigate the digital universe. However, the cost is also high.

🦁

MAI (Reporter)

In the actual observation footage, warnings indicating zero energy remaining were also confirmed.

KANAME🦁 (Expert)

They must have been flying beyond their limits. Under normal circumstances, they would have stopped. But Nadeshiko didn't stop.

🦁

MAI (Reporter)

Towards the end of the footage, Lady Nadeshiko also appears to be crying.

KANAME🦁 (Expert)

Yes. But the reason is still unknown to the analysis team. Is it anger? Sadness? Or another emotion?

🦁

MAI (Reporter)

And just before the recording ended, Lady Nadeshiko uttered the same name again. "YUI"

KANAME🦁 (Expert)

... I can't talk about that yet.

🦁

Episode 5: AURA SPHERE ── Analysis complete.
AURA SPHERE reaction officially recorded.
Unregistered signal "YUI" is under continuous observation.
