Fantasy Assassin in a modern world

It was another day in this new world for Loki and today seems to be some sort of special day. He had noticed while walking that the neighboring houses were decorated with different kinds of spooky and creepy objects, from spider webs to fake skeletons. Based on the memories of the previous owner of his body, today was a day called Halloween. 

Even though many had forgotten the original purpose of the day and it had been reduced to a day for kids and adults to have fun, the previous Loki who was a bookworm knew the original intent of the day. Today was supposed to be a day when ghosts would roam the world, and the wearing of scary costumes was to ward them off. 

Even someone like Loki who came from a world that was considered to be a fantasy didn\'t really believe in such things as ghosts. 

\'If ghosts were real then why hasn\'t my sister haunted me... After failing her so much, I\'m sure that she would\'ve haunted me all the time...\' Loki shook his head as the thought passed by his mind. 

He returned to his house and when he opened the door he saw both Alisa and Liam were wearing costumes. Alisa was wearing a pirate costume while Liam was wearing a vampire costume.

"Big brother, what are you doing, why haven\'t you changed into your costume?" 

"Huh?" 

"I think this fool actually forgot that we\'re supposed to go to the neighbor\'s costume party." 

When Loki heard what Liam said he now vaguely remembered that Alisa did tell him about that party, he just couldn\'t remember when. He was going to give some random reason like he needed to do some work and he couldn\'t attend. As he was thinking about a way to avoid the party, Alisa looked at him with a little bit of disappointment on her face. 

"Big brother, did you really forget?" When Loki saw the expression on Alisa\'s face he immediately erased any thoughts of evading this party. 

"Of course, I didn\'t forget." 

"Oh really, then where is your costume?" Liam asked with a sneer. 

"It\'s upstairs just give me a second to change into my outfit."

...

After waiting for a few minutes Loki came down wearing what he usually wears as Fade. When the two saw him there was a look of surprise on their faces. 

"Oh man, that\'s the best costume I have ever seen, you actually look like the real thing." Liam praised as he looked at Loki. 

"Where did you get this?" 

"I had it prepared a few weeks ago. See I told you I didn\'t forget." Loki smiled underneath the white mask. It was a good thing he saw a few kids outside wearing the same thing, so he figured that he could just wear it today and no one would ever suspect him of being the real thing. 

...

The siblings headed to the party next door and as expected almost everyone had praised Loki\'s look as it felt very authentic. If they didn\'t know that it was Loki underneath the mask they might have truly believed that he was the assassin from the urban legend. 

After greeting the host of the party, Loki retreated to the second floor of the house wanting to separate himself from the crowd of people. He arrived at an empty hallway planning to escape, since he had already come to the party he had fulfilled his promise. As Loki was about to sneak away, he suddenly heard someone speak from behind him. 

"You\'re the real Fade, right?" 

Loki turned around and was surprised to see a woman wearing a white dress standing there. He didn\'t even notice her coming close to him, which frightened Loki a little bit. 

"I don\'t know why you think that, but this is just a costume." 

"I know that isn\'t true. Please I won\'t tell anyone, so please you\'re my only hope, help me." The woman spoke with a desperate and pained expression on her face. 

"Okay, alright calm down, first thing who are you?" 

"I\'m Natasha Rolin." 

"Alright, Natasha let\'s just say that I\'m really Fade, then what is it you want me to do?" 

"I want you to kill someone to save my friend."

"... Alright, tell me your story first." 

Natasha then started to explain that her friend was with a dangerous person who was supposedly that friend\'s boyfriend. Natasha explained that the boyfriend was a bad person who was related to a recently disbanded gang. The boyfriend had supposedly committed tons of crimes which were mostly r*pe and homicide. After listening to her story, Loki knew that if what she was saying was true then this person was indeed worthy to be his target. 

"Please you got to go quick, I\'m afraid that he might do something terrible to my friend today." 

"Alright, first we need to leave." Loki tried to grab hold of the woman\'s hand but she quickly backed away with a bit of fear on her face. Seeing her expression Loki sighed as he spoke to her.

"Just follow behind me." She responded by nodding her head. 

Loki and Natasha went downstairs were they immediately bumped into Alisa.

"Big brother where do you think you\'re going?" 

"Sorry Alisa, I need to leave early I forgot that I needed to do something important today." Alisa looked at her brother and sighed before she responded.

"Fine, I already know that you didn\'t really want to come. It\'s already a good thing that you tried for me. Liam and I will stay, so you can go." 

"Thanks," Loki quickly left the house. While walking outside Loki took out his phone and tried calling Harold. No one was answering the phone, it was then that Loki remembered that Harold messaged him that he and his family were going on a trip today and he would be unlivable for the next two days. 

\'Tsk, I wanted to confirm her story and background, but I guess I can ask Harold later. I\'ll check for myself what kind of b*stard this boyfriend is.\' 

"Alright, so tell me where does this boyfriend live?" 

...

Loki and Natasha arrived in a rundown apartment complex, and as they were going to knock on the door of Natasha\'s friend\'s apartment, Loki suddenly heard a gunshot. 

"Tsk, you stay here." Loki quickly kicked down the door, and he saw a woman on the floor crying and a man pointing a gun at her while beating her up. The man noticed Loki and so did the woman. 

"HELP!"

The woman screamed and the man was going to point his gun at Loki, but before he could do so he felt something wrapped around his hands making him unable to move. The man then felt the same invisible thing that had wrapped around his hands now one his neck squeezing the life out of him. The woman unaware of what was happening saw that the man was no longer hitting her quickly ran towards Loki. 

"Please help me, he\'s trying to kill me!"

Loki nodded his head and came closer to the man and with one hit knocked him out. Loki was going to kill the man later when the woman wasn\'t looking. Seeing that Loki knocked out the man with a punch the woman cautiously approached him. 

"Thank you for saving me." 

"Don\'t thank me, it was your friend that called me here to help." 

"My friend?" 

"Yeah, your friend Natasha." The moment that name came out of Loki\'s mouth the woman\'s expression changed. 

"Wait, are you talking about Natasha Rolin?" 

"Yeah, why?" 

"Natasha has been dead for two years now. She was killed after being-" The woman couldn\'t even her sentence before she started crying, on the other hand, Loki was stunned into silence. He looked outside the room and saw that Natasha was no longer there. 

Loki then remembered how he met Natasha, he couldn\'t sense her approaching. She was quick to react and didn\'t want Loki touching her. When they passed by his sister, Alisa didn\'t even ask who the lady following him was. Then when Natasha heard the gunshot she wasn\'t surprised nor did she show any fear.. There were so many signs and as the pieces of the puzzle were fitting in, Loki couldn\'t believe that there was the possibility that he had met an actual ghost.
