Somewhere in the Czech republic. In the suburbs. In a rap club.

There was a young almost 20-year-old boy called Marco. He had deep blue eyes and brown hair and a butterfly tattoo on his back in honour of his dead friend.

Marco was waiting for a rap battle against his biggest enemy and rival, Lojza, the guy who killed his friend a few years ago, but the police had never proved his crime.

Marco had been preparing for that day for a very long time. He could not decide what was worse - the fact that he would challenge Lojza or that he had never been to a rap battle before.

The fear overwhelmed his mind and body. What would happen if he lost the battle? Would he die like his friend? He had so many questions but there was no way back. He had to face him. Marco had lost the toss and it was Lojza to start the battle.

When Marco was about to start a loud bang was heard, like a shot. Some people started screaming and running searching for an exit door.Then a lot of sirens were getting close to the place.

Marco couldn’t think about anything else but his dead friend José Antonio. It was pitch dark. The image of his friend was painful, being death or dying wasn’t important for him at that moment. Marco saw the killer in front of him, holding the gun, and he jumped on him in a rage attack. Another shot, blood in his stomach, a bullet in his body. Was he dead? A big light appeared in front of him, was that Heaven?

Marco woke up in the hospital, with a big pain in him, without remembering anything, just his friend's face the day of his death. He wasn’t aware of what had happened. How did he end in that room? Who killed his friend? Only trying to remember it, his head hurt so much.

He realised something was wrong at the moment he saw the doctor's face:

TheDoctor said: - I know you have lots of questions but, you need to rest now. You have been two years in a coma. Memories will come to you slowly, don’t worry.

I couldn’t distinguish which ones of my memories were real and which ones were not. There was just one thing in common. A lot of darkness.

It had been a month since I woke up. I recovered pretty well, but my head hurt really bad when I tried to remember something.

It was Wednesday, I was at home and was taking a shower. When I got out I saw a glimpse of something on my back. I took a photo in the mirror and when I looked at it I saw a butterfly tattoo.

I fainted, but when I woke up I was somewhere else. The place looked familiar. Then I saw... Antonio, my dead friend. The whole scene where he was killed was happening in front of my eyes. I couldn't see the person that shot him, but I saw a strangely familiar tattoo on his arm. It looked like a weird skull key.

Then I woke up in the bathroom, full of sweat. The tattoo... it had to mean something. My duty was to figure it out.

I spent a week searching through books and on the Internet but all I found were kids' creepy stories about a cursed key. I was exhausted and stressed, so I went to a bar to get drunk.

I was about to lose all my hope, when I saw the same mark on a sign above a VIP room. The bar tender told me that was the symbol of a well-known Mafia. He smirked at me and asked me whether I would like to join it. Without thinking too much, I said yes.
