A/N: Yes, you've got it. I just mixed two famous plot lines together: self insert OC and Tsuna having an evil twin brother. I had this random moment to try how the two fit together, so here I am, writing a new KHR fanfic. This is my first time attempting anything so dramatic and angst-ish so I hope that I entertain you guys at the least. English isn't my first language so I apologise for any mistakes or grammar mistakes! Updates will be fairly slow so bear with me! :)

Prologue

I hear the sound of chains, harsh metal clanking against the stone floor underneath me, supporting my weight. Cold hesitant light streams in through the cracked window on the door, blanketed in heavy thick layers of dust.

I stare down at the shackles on my wrists and the golden gleaming key in my hands. I hear the heavy metal door creak open, the sound echoing throughout the empty room. A cold shudder trickles down my spine as more light enters through the gap of the open door. I stare at the person who walks in after the door, a face I had grown very accustomed to ever since I was locked up inside this cage.

Three years.

My fingers clench on the golden key in my hand, my anger rising as all the mental simulations of my life for the past three years replayed in my mind like a broken record.

It's now or never.

Before the man would notice the stolen key in my hands, I quickly slide the key into the hole of my shackles. His eyes widened as I quickly spin the key, feeling the weight fall of my wrists. As he takes a step forward, I launch my entire body at him, knocking the air out of him. He crumbles down to the ground, back slamming with a thud against the stone wall, a scream making its way up his mouth. Without a second thought, I turn towards the door, swing it open, and run.

Heart pounding, head screaming, feet aching. As I run down the familiar hallway, I see a small crowd of guards heading my way. Taking a deep breath I ram myself into the sea of guards, ignoring the shrieks and profanities directed at me. Their hands try to reach me, to force me back, but I was faster than them.

Shaking away their grip, I hear them demanding for me to halt, yelling to each other that the goddamn hacker had escaped. I sprint down the staircase, tripping on the third step and rolling down the stairs.

The whole place was in pandemonium. Guards were flying out here and there, people were running into each other as I continue on sprinting and making my way to freedom. I glance back at my pursuers for a moment, my sweat-soaked hair whipping in the wind.

They were carrying guns.

My face pales as I immediately pick up my speed, making a sharp turn to the right and sprint for the exit. As I sprint past the exit door, feeling crisp clean air brush against my face. The smell of it was soft and pleasant like the smell of freshly-cut grass and various types of flowers. It was a smell that used to be normalcy for me, that is, before I was caught. In front of the building was a large garden.

Well no wonder it smelled like grass...

"There she is!" My eyes widen as I hear my pursuers reaching closer and closer to me.

From the corner of my eye, I see a pier nearby. A motorboat was floating in the clear blue sea, right next to the pier. If I could reach the pier, I could leap into the boat and ride off into the horizon, far away from their grasp. Frantically, I ran down the steps in front of the building, leaping over a wooden bench in the process, heading over towards the pier. It was dark outside and there was no one wandering around - no one to hear my cry for help.

The footsteps of my pursuers still linger behind me as I rush past the garden, my feet screaming and aching. I reach the small alleyway that would lead me directly to the pier. My hands slap against the dusty old red bricks as I leap over a pile of aluminium trash cans. Accidentally knocking a few over, like dominos, the rest of the cans clatter around behind me and bounce down the alleyway like a startled school of sardines.

As I continue on my path down the alleyway, I hear the sounds of the guards behind me, yelling profanities at the aluminum mess I had created a few seconds earlier. Inwardly grinning to myself, I allow the cans to bind me some time.

Leaping over the last pile of trash in the alleyway, I turn towards the pier, only a few meters in front of me. A small smile creeps up onto my face as I swiftly make my way towards the pier. The soles of my worn-out shoes dig into the wooden planks on the pier, the sound of wood filling my ears, as my heart thunders louder and louder. I reach the boat and without wasting even a millisecond, I throw myself into the boat, my body crashing into the seats. Placing my elbows on the seats, I lift my head up from the boat and see a few guards already making their way out of the alleyway.

There was no more time left to waste. I turn towards the key hole to start up the boat only to freeze cold.

There was no key to be found.

Scrambling to find the key, I found out that the amount of oil in the boat was also incredibly low. My heart sank like a coin being thrown down a wishing well, except I wasn't about to have any of my wishes granted.

Hearing the sound of footsteps directly behind me, I force out a dry laugh.

So this is how it all ends?

"This is unfortunately where it all ends," the same man that I had knocked out at the beginning in my cell stands before me, eyes blazing with fury and anger.

I scoff out loud. "As if I couldn't deduce that myself."

All the guards raise their guns at me as I stare blankly back at them. "Don't be such a smart ass. You won't be getting out of this one. What did I tell you when the day I first locked you up in that cell?" the same man stated.

"...Tell what you found or attempt to escape and your life is as good as done." I calmly retort back.

"And after three years, the deed has been done. What a fool. If only you stayed put in that tiny cage of yours, you would have at least been able to live longer," the man speaks in a mocking tone, as if he was feeling pity for me.

As if a mafia boss who brutally slaughtered someone's parents would feel pity for a young girl like me.

"I would rather be dead than live in that pigsty for the rest of my life," I retort back, knowing fully well what the consequences would be and as I feared, the man ordered his men to place their fingers on the trigger. Mentally saying my last words, my lips contort into an exhausted, strained and pained smile. "Would you be so kind to grant me that wish?"

A satisfied smile played on his lips. "Gladly, my dear."

An intense amount of pain shot through my whole body at once, my vision turning white. I see my own flesh and blood being torn apart, the red specks flying mid air and the golden gleam of light from the gun shots. I let loose an inhuman scream, before I feel my body being lifted off the boat and sinking into the large body of water below.

The water, heavy and suffocating, fills up my lungs as I choke underneath the water. The pain increases as I struggle to tread up back to clean air. But my body can no longer move, as the pain becomes too much for my own body to handle. My breath slows and I can no longer hear the thundering sounds of my heart beating. A wave of intense coldness hits me as I sink deeper and deeper into the ocean.

My eyes, blank and lifeless, stares at the darkness surrounding me. My eyelids grow heavy as it becomes harder to breathe.

Weightless, painless, and lifeless.

I stop breathing altogether.

My last vision was a vast endless sea of dazzling blue - the most clear and beautiful sky I had ever seen.

I know things may seem a bit confusing now, but of course, things will be clarified as the story moves on. Leave a review before you leave! Thank you for reading! :)
