### **Part 1: The End of a Fool**
**[Earth – Tokyo, Nighttime]**
Rain poured like tears from the heavens, slicking the neon-lit streets with reflections of a city that no longer cared.
*"Why…?"*
Kazuki "Kairo" Soryu collapsed to his knees, crimson pooling beneath him. The knife embedded in his gut wasn't the worst pain—it was the faces of the five girls standing over him, their eyes cold, hands stained with his blood.
**Ayame**, his first love, adjusted her glasses, her voice devoid of emotion. *"You were too trusting, Kazuki. In this world, weakness gets you killed."*
**Mirai**, the childhood friend he'd protected for years, kicked him onto his back. *"You really thought we loved you? You were just a tool."*
Laughter. Mockery. The sound of heels clicking away as his vision darkened.
*"I… hate you all."*
His last thought before death wasn't of revenge—it was the crushing weight of betrayal.

### **Part 2: The Dragon's Lament**
**[Unknown Realm – Void Between Worlds]**
Consciousness returned in fragments.
*"Am I… dead?"*
A voice echoed—ancient, wounded, filled with the same fury he'd felt.
*"You… were betrayed… as I was."*
Images flooded his mind:
- A **cosmic dragon**, scales shimmering like galaxies, soaring through dimensions.
- A **blade of light** severing its tail—the source of its power.
- The dragon's **final roar** as it crashed onto a barren planet, bleeding and broken.
The voice growled. *"They feared my power… as they feared yours. Now, we are one."*
**Kairo's soul surged into the dragon's dying body.**

### **Part 3: A Monster's Awakening**
**[Earth – Dragon Ball Universe, Wasteland]**
Agony.
Every cell in Kairo's new body screamed as he **regenerated**. His form was neither human nor dragon—a **humanoid with olive skin, golden slit pupils, and jagged horns**. His tail, severed at the base, twitched uselessly.
*"What… am I?"*
He stumbled, collapsing into a ravine. His claws dug into the earth as memories merged:
- **Dragon's Skills:** *Regeneration*, *Agelessness*, *Pain Immunity (but not resistance)*.
- **Weakness:** No tail = **no true dragon form**.
A voice boomed behind him.
*"Hey! You alive?"*
Kairo turned—**orange gi, spiky hair, a grin brighter than the sun**.
**Son Goku.**

### **Part 4: The First Meeting**
Goku tilted his head. *"Whoa. You're not a Saiyan. Or a human. What's with the horns?"*
Kairo's instincts flared—*danger!*—but his body gave out.
**[Hours Later – Capsule Corp]**
Bulma's scanners beeped frantically. *"This is insane! His cells are rewriting themselves!"*
Vegeta crossed his arms. *"Tch. Another freak for the collection."*
Goku poked Kairo's forehead. *"Think he's evil?"*
Bulma smirked. *"Only one way to find out."*
---
### **Part 5: Truth and Tears**
When Kairo awoke, he **told them everything**.
- His betrayal.
- The dragon's memories.
- The **void where his tail should be**.
Goku's fists clenched. *"Man… that's rough."*
Vegeta scoffed. *"Weaklings dwell on the past. Surviving is what matters."*
Kairo's nails dug into his palms. *"I want… power."*
Bulma grinned. *"Then you're in the right place."*
---
### **Part 6: The Training Begins**
**[Next Day – Gravity Chamber]**
Vegeta smirked. *"Let's see if a lizard can keep up."*
**50x Gravity.**
Kairo's bones creaked—but he **stood**.
Goku laughed. *"Alright! Now, let's teach you how to go **Super Saiyan**!"*
Kairo's golden eyes burned.
*"I'll become stronger than anyone… so no one can betray me again."*
