Fantasy Assassin in a modern world

The young man fled with all his might as he jumped from building to building. Once he was a few kilometers away from the Martial arts Department building the young man checked if he was being followed, when he confirmed no one had followed him he laid on the ground.

He then started checking his current condition, his right hand was not responding, though his left hand was nearly broken and the pain was a little bit difficult to bear it was still moveable. He also had four broken ribs and was internally bleeding. There was no damage to his legs and he had a slight concussion. Overall he was still in a relatively okay state considering how powerful that unknown person he fought was. 

Even now he was feeling the lingering fear of facing that unknown martial artist. He could not understand what had happened but he knew that he was so close to death. In fact, the young man felt that for some unknown reason the martial artist covering his face was going easy on him. Now that he started thinking about it, during the unknown martial artist\'s sudden boost of strength there were many times he could\'ve precisely hit a vital area using his needles and killed him but didn\'t. 

The young man shook his head and stopped thinking about it, what he needed to do now was escape this place and meet with his commander. The young man looked around and once he was sure no one else was present he headed to a specific condominium building and entered from the roof. He then went into a room took off his clothes and changed. After he was done changing the young man headed out of the building through the front door and called for a taxi. 

He got off in another part of the city and entered a restaurant, even though he was still injured most of which was internal except for his limp right hand. Still despite people looking at him curiously the young man was not bothered and ate a meal. After he was done the young man took another taxi and then walked towards a train station, entered the underground station looked around but did not ride a train, he then finally walked towards a crowded area and disappeared.  Even the CCTVs in the train station were unable to tell if he left the station or not.

Loki\'s POV:

When I opened my eyes I was in a familiar place that I haven\'t seen in years. It was the flower field that my little sister took care of that was hidden in the back of my old clan. Back then when the b*stards had killed my sister they had burned this place to the ground. As I was confused as to what was happening I heard her voice. 

I\'ve been hearing her voice in my head for years now, but this was the first time I felt like I truly heard her speaking in my ears. I looked behind me and there she was, my beloved sister Shera. I slowly approached her and touched her, when I felt her in my hands I knew that she was real, no I wanted her to be real. It was at that moment a single thought came to me and I chuckled as I cried in front of her. 

"Hehehe, I guess I finally did it, I finally died. Still, I wasn\'t expecting to be able to get to the same place as you. My hands that have been stained by the blood of many, I was sure that I would never be able to go to the place you went... But, it seems I got lucky. So Shera, was I able to fulfill my promise, did I become your ideal assassin?" 

Shera smiled ever so sweetly as she held my hand and looked at me. 

"You\'ve done so well big brother. I know how many you have saved while staining your hands with blood. I know how many times you were hurt both physically and emotionally. I know how hard you worked to fulfill your promise." 

As Shera was talking the smile on her face slowly disappeared and was replaced with a crying one. She looked at me with tears in her eyes. I stepped forward and gently wiped away her tears.

"If I did so well, then why are you crying?" 

"I\'m so sorry big brother!" 

"Huh, why are you apologizing? There\'s nothing to be sorry about." Shera then started to shake her head. 

"No, big brother. That promise that you made with me upon my death was a curse I placed on you. It was a selfish desire that had bound you to a life filled with pain and bloodshed. If not for that stupid selfish promise that you made with me, you would\'ve found happiness long ago. I\'m so sorry, I\'m so sorry." 

"Hey no need to talk like that, that wasn\'t a curse, no, to me on that day what you have given me was a gift. If not for that promise on that day, I would\'ve become a killing demon. I would\'ve just killed and killed to let out all of my anger. If not for that promise I wouldn\'t become the person I am today, and I love the person that I have become because of you. So there\'s no need to say you\'re sorry, but instead, I need to thank you for the gift that you have given me."

I hugged my little sister and amidst her crying, a smile returned to her face. 

"You truly are the best big brother. I was truly lucky to have been your little sister." 

"Enough about that, it doesn\'t really matter now since it\'s all over. Now that we\'re finally together I can finally rest." 

The moment I said those words, Shera pushed me to the side. I was confused as she shook her head and smiled at me. 

"Sorry big brother, it\'s not your time yet." 

"What do you mean it\'s not yet my time?!" 

"I\'m glad that you still think about me big brother, and that you still wish to fulfill your promise, but now that you\'re in that new world, were you can live a different life, why don\'t you try living for yourself this time... I hope that you find the happiness you deserve big brother." 

I was about to answer but for some reason, my voice wouldn\'t come out. I then saw Shera slowly backing away, I tried my best to follow but no matter how hard I run, no matter how I stretched my hands I couldn\'t reach her. I then started falling into an abyss. 

...

Loki slowly opened his eyes, he looked around and saw a worried Ashley and Liam sitting beside his bed. 

"Big brother!" The two of them shouted. 

"Huh, where am I?" 

"We\'re in the hospital." 

"The hospital?... What happened?" 

"That\'s what we want to ask you, how come you always make us worried like this you idiot!" Liam spoke as he tried his hardest to hold back his tears. 

"Don\'t you remember anything big brother?" Alisa asked, in which Loki shook his head. 

"I\'m not sure, but I think something important happened... I think I spoke with someone dear to me... I can\'t really remember..." 

Loki tried remembering what happened before he passed out, and he did remember that he was fighting someone, and he was forced to use an untested technique. The young man he was fighting retreated... After that, he couldn\'t remember, but he was sure that there was something more important that happened after that. Yet no matter how hard he tried he just couldn\'t recall it. 

"Big brother why are you crying? Liam go and call a doctor. Are you feeling uncomfortable, where does it hurt?" Alisa started to panic while Liam headed out to call a doctor. 

Loki who heard what Alisa said touched his eyes and noticed that he was indeed crying.. He tried wiping his tears away but they just kept on flowing.
