After Z and Y's victory against the **Void Executioner**, the OverKaizer siblings regroup in the celestial stronghold known as **Astra Citadel**—a hidden fortress located between dimensions, where time and space are stable.
This episode marks the first time all five siblings—**Lyz, Z, X, May, and Y—stand together in one place** since their rebirth.

### **The OverKaizer Siblings: Together Once More**
X leans against a floating platform, grinning at Z. **"So? How was it? Get erased yet?"**
Z **clicks his tongue**, crossing his arms. **"Tch. Like that oversized glitch had a chance."**
May excitedly tugs on Y's sleeve. **"Did you see anything cool, big bro?"**
Y nods. **"We fought a being that could erase people from history itself. If we weren't OverKaizers, we'd be gone for good."**
Lyz closes her eyes, deep in thought. **"That confirms it, then. The Calamity isn't just watching us—it's testing us."**
X raises an eyebrow. **"Testing us? For what?"**
Lyz opens her **Book of All**, flipping through cosmic records. **"The Calamity isn't reckless. It has existed since before even our parents. If it's making moves now, it means it believes we are a true threat."**
X smirks. **"Good. Then let's prove it right."**
But before they can continue—
> **BOOM!**
The entire **Astra Citadel trembles**, as if the fabric of reality itself is being **crushed**.
A deep, unnatural voice echoes across dimensions—
> **"OverKaizers… you have gathered. Perfect. Now, witness true devastation."**
The sky above them **rips open**, revealing a massive, **twisting mass of darkness**—something that should not exist.
**The Calamity has made its move.**

### **The First Strike: Cosmic Corruption**
From the **tear in reality**, black tendrils of **Calamity Essence** pour out, spreading like a **cosmic virus**.
- The **stars begin to flicker and die**.
- The **ground distorts**, turning into a **liquid void**.
- **Time slows and speeds up randomly**, as if the laws of physics are being rewritten.
May gasps, her **Void-Piercing Arrows** glowing. **"This isn't just an attack… it's corruption!"**
Lyz's eyes narrow. **"It's trying to consume Astra Citadel into its void."**
X clenches his fists, his **Slime Power evolving** in response to the overwhelming energy. **"Then we fight back!"**

### **The Battle Against the Corruption**
Each sibling takes action:
- **Lyz raises her wand**, summoning barriers of **Pure Arcane Law** to hold back the spreading corruption.
- **Z dashes into the chaos**, his **Katana-Scythe slicing through the tendrils**, severing them before they can spread further.
- **May fires void-powered arrows**, piercing the infected sky and **stabilizing** the collapsing dimension.
- **Y slams his shield into the ground**, creating a reinforcement field that **anchors reality in place**.
But despite their efforts, the **Calamity's corruption is endless**.
Then—X steps forward.
His **Slime Power surges**, transforming into a **primordial consuming force**.
X grins. **"You want to devour this place? Let's see who's hungrier."**
His **Slime Ability evolves into Absolute Devourer Mode**, allowing him to **absorb and neutralize the Calamity's essence directly**.
He raises his hand—**and the corruption stops spreading.**
The tendrils of darkness are **sucked into X's body**, but instead of corrupting him, they are **purified and turned into raw power**.
> **The Astra Citadel is saved.**
The siblings take a breath, but they know this is only the beginning.

### **A Final Message from the Calamity**
The voice of the **Calamity** echoes once more, its tone both amused and disappointed.
> **"Impressive. But this was only a test. Next time… you will face despair itself."**
The **tear in reality closes**, leaving the siblings standing in the aftermath.
Y frowns. **"That wasn't even its full power."**
Lyz nods. **"No. It was only probing us. Which means we have little time before it attacks for real."**
X cracks his knuckles, his grin returning. **"Good. Let's get stronger, then. Because when we fight next… I'm gonna make sure the Calamity remembers my name."**
