Story
After Zero — Chapter 1: The World After Zero
Genre: Sci-Fi, Action, Mystery, Post-Apocalyptic
Humanity once lived in a world much like our own—modern cities, advanced technology, smartphones, airplanes, and peaceful everyday life. Then came the catastrophe known as Zero.
A devastating nuclear war nearly destroyed civilization. Billions died, cities were reduced to ruins, and the survivors were forced to hide inside enormous shelters. Over generations, humanity rebuilt itself. The shelters became massive fortified cities, new technologies were developed, and civilization slowly became stronger than before.
But Earth had changed.
Animals exposed to the aftermath evolved into dangerous creatures known as Beasts. At the same time, some humans began developing extraordinary abilities. These people became known as Awakeners.
In the present day, Awakener schools train young people to control their abilities, while elite military academies prepare Awakeners to defend humanity from the Beasts beyond the city walls.
Our story follows a teenager born long after Zero. He has never seen the Old World and has grown up believing the history taught in school: humanity destroyed itself through nuclear war.
As he prepares for the entrance examination to an Awakener Academy, his ordinary life suddenly changes when a powerful Beast breaches the city's outer defenses.
But the Beast isn't behaving normally.
It appears to be searching for something buried beneath the city.
Far underground, hidden beneath layers of forgotten civilization, an ancient machine awakens for the first time in centuries.
A forgotten system comes online.
EXTRATERRESTRIAL SIGNAL DETECTED.
The people of the modern world believe humanity survived the end of civilization.
They don't know that the end of the old world was only the beginning

![# ⚡ OMEGA — MANGA OVERVIEW
**Genre:** Action • Fantasy • Mystery • Supernatural • Adventure
**Format:** Manga
**Season 1:** 12 chapters
**Main protagonist:** Kurokawa Ren, 18

## 🌍 THE WORLD
Twelve years before the story begins, mysterious dimensional portals called **Gates** started appearing across Earth.
The Gates connect Earth to a completely different reality known simply as **the Other World**.
The Other World is filled with strange environments, mystical energy, creatures, ancient civilizations, and secrets that humanity barely understands.
Some humans exposed to the mystical energy developed supernatural abilities.
These people became known as:
### **Omega Agents**
The organization called **Omega** was created to monitor the Gates, protect humanity, explore the Other World, and eliminate dangerous threats.
Every Agent has an **Omega System** that monitors their abilities, energy, rank, class, missions and overall performance.
---
# 🧑🏾 Kurokawa Ren
Ren is an 18-year-old Omega Agent.
He's capable, but he's nowhere near the strongest Agent.
He's calm, sarcastic, observant and loves messing with people.
His official ability is:
### **Mystic Perception**
It allows him to see and understand mystical energy.
At the beginning, Ren is simply **Rank 47**.
Nothing particularly special.
Until one mission changes everything.
---
# 👥 TEAM 47
Omega creates teams based on ability compatibility.
Ren gets assigned to a five-person squad:
### **Ren**
Strategist / Vanguard
### **Hikari**
Medic / Support
Ability: **Life Thread**
### **Shiro**
Vanguard / Powerhouse
Ability: **Kinetic Forge**
### **Kiyoshi**
Recon / Infiltration
Ability: **Phase Shift**
### **Itsuki**
Striker / Long-range support
Ability: **Astral Arsenal**
They weren't secretly chosen by fate.
They aren't some legendary group.
Omega simply calculated that their abilities work well together.
And that's important.
---
# 📖 SEASON 1
Season 1 follows Ren's gradual transformation.
At first, it's a normal Gate-adventure story.
But after Ren encounters something that **predates the Gates themselves**, the story slowly becomes a mystery.
The main question becomes:
> **What happened to Ren?**
And even more importantly:
> **Why can't Omega's system detect it?**
---
# 📕 CHAPTER 1 — THE GATE
The manga begins by introducing the Gates, Omega, the Other World and Team 47.
Team 47 is sent into a C-Rank Gate in Tokyo.
They enter the Other World and successfully fight several creatures.
During the mission, Ren begins noticing strange patterns in the creatures' mystical energy.
Eventually, the team discovers an ancient-looking flower.
Ren's Omega System can't identify it.
The ground collapses, separating Ren from the others.
He finds the flower again in an underground chamber.
Ren touches it.
### Everything changes.
The flower disappears.
Ren loses consciousness.
When he wakes up, his normal Omega System appears completely unchanged.
But underneath it is another system.
```text
[UNKNOWN SYSTEM INITIALIZING]
[FOREIGN SYSTEM DETECTED]
[AUTHORITY AWAKENED]
[OMEGA SURVEILLANCE: BYPASSED]
```
Ren realizes something has happened to him.
And he knows one thing immediately:
### **Omega cannot know.**
The chapter ends with Ren opening his newly changed eyes.
---
# 🔥 CHAPTERS 2–3 — THE OTHER SIDE / THE FLOWER
Ren and Team 47 continue dealing with the Gate.
Ren begins experiencing strange changes.
His perception becomes much sharper.
He starts seeing things that the normal Omega System doesn't report.
Eventually, Ren realizes the flower wasn't ordinary.
It belonged to an ancient species that existed **before the Gates**.
And the flower he touched was the **last one in existence**.
After Ren touched it, the species became completely extinct.
No seeds.
No second flower.
Nothing.
Ren is now the only remaining trace.
But he doesn't yet understand what that means.
---
# ⚡ CHAPTERS 4–6 — THE AWAKENING
Ren secretly experiments with his new abilities.
His hidden power begins developing through different stages.
### Perception
He can understand mystical energy at an abnormal level.
### Adaptation
His abilities gradually respond to different mystical phenomena.
### Suppression
He discovers he can weaken supernatural abilities around him.
### Authority Theft
After defeating certain opponents, he can temporarily borrow aspects of their abilities.
But Ren has a problem.
### He doesn't know his own limits.
So these chapters are about Ren learning how to use his powers without exposing himself.
Meanwhile, Hikari begins noticing that something about Ren isn't quite right.
She doesn't know the truth.
Nobody does.
---
# 🌌 CHAPTERS 7–9 — THE DEEP GATES
The team begins encountering stranger Gates.
Some creatures behave differently.
Some Gates don't follow Omega's established rules.
Ren's hidden system occasionally gives him information that Omega's system doesn't have.
This makes Ren suspicious.
He starts wondering:
> **Does Omega actually understand the Gates?**
At around this point, something else happens.
---
# 👑 THE ELITE RANKING MEETING
For the first time, the five Elite Ranks hear about Ren.
Not because they've been secretly watching him.
Not because they know about the flower.
Simply because Omega is reviewing Agent rankings and discussing promotions.
Ren's name appears:
> **KUROKAWA REN — RANK 47**
The Elite Ranks don't know who he is.
But Rank 1, **Kanzaki Ryouma**, notices something strange about his report.
And Rank 0, **Kurosawa Reiji**, has a brief reaction that nobody understands.
He simply says:
> **"Proceed."**
That's our first tiny clue that something bigger is happening.
---
# 💥 CHAPTERS 10–11 — THE BREACH
Team 47 encounters one of their most dangerous missions yet.
A Gate becomes unstable.
The team is overwhelmed.
Ren has no choice.
He begins using abilities that his official Omega profile shouldn't possess.
He uses his hidden Authority to save the team.
But he does everything possible to make it look like ordinary Mystic Perception and tactical skill.
He succeeds.
The team survives.
Omega still doesn't understand what happened.
At least...
that's what Ren thinks.
---
# 👁️ CHAPTER 12 — THE ANOMALY
The Season 1 finale.
Ren's hidden system suddenly displays:
```text
[EXTERNAL SYSTEM DETECTED]
[AUTHORITY SIGNATURE IDENTIFIED]
[OMEGA SURVEILLANCE FAILURE]
[ANOMALY DETECTED]
```
For the first time, Omega's monitoring network notices something impossible.
Something inside Ren.
Omega analyzes the data.
And eventually—
### **Kurokawa Ren is flagged as an anomaly.**
Ren doesn't know exactly what Omega has discovered.
But somewhere inside Omega headquarters...
his file changes.
```text
KUROKAWA REN
RANK 47
STATUS:
UNDER REVIEW
ANOMALY:
DETECTED
```
Ren looks at the screen.
His usual smile disappears.
### **END OF SEASON 1.**
---
# 🧩 THE BIGGER STORY
And this is where OMEGA becomes much bigger than Ren simply getting stronger.
There are **nine major figures** connected to the larger mystery:
### 👑 The Five Elite Ranks
* Rank 5 — **Takamine Raiga**
* Rank 4 — **Kanzaki Shizuru**
* Rank 3 — **Kisaragi Touma**
* Rank 2 — **Amamiya Setsuna**
* Rank 1 — **Kanzaki Ryouma**
### **Rank 0**
**Kurosawa Reiji**
He appears to run Omega.
But he doesn't.
Someone else is actually controlling Omega from the shadows.
### 🌸 The Gardener
**Hanabusa Shion**
Caretaker of the final ancient flower.
### ⚠️ The Defector
A former Omega Agent whose reasons for leaving are unknown.
### ❓ The Unknown Enemy
A mysterious enemy whose identity and goals are hidden.

# 🔥 THE CORE MYSTERY
At first, the story looks like:
> **Humans vs creatures from another world.**
Then it becomes:
> **What are the Gates?**
Then:
> **Why did the flower exist before the Gates?**
Then:
> **What exactly is Authority?**
And eventually:
> **Who actually controls Omega?**
And finally:
> **Why was Earth connected to the Other World in the first place?**
That's the long-term mystery we're building toward.
So the manga starts relatively simple...
**Gate → Mission → Team → Fight → Mystery**
...
and slowly turns into:
**Earth → Other World → Ancient powers → Omega's secrets → Ren's Authority → whoever is really behind everything.**
😭🔥 **That's OMEGA.**](https://media.mangamaker.com/dd00a1dc-ae25-4a57-88a5-b33feaf7fe96.png)

Panel 1: The boy stands close to a video camera mounted on a tripod, pressing the 'REC' button to start filming. He is looking down at the camera with a sigh. The background shows a chaotic bedroom with a wall covered in band posters and a rumpled bed. Sound effects: [SFX: CLICK].
