Fantasy Assassin in a modern world

Loki had just been discharged from the hospital and when he was in the taxi going home he noticed that there were many weird decorations all around. It was similar to Halloween but somehow different. It was at that moment he got a memory rushing through his mind. 

Loki learned that today was something called Christmas and it was formerly a religious event but nowadays it turned into a commercial event where people buy gifts to give each other. When this memory came back to Loki, he immediately told the cab driver to head to any place where he could buy some gifts. 

Loki didn't know that there was such a tradition in this world and went to the nearest mall, unfortunately, they were closed. Loki tried to find any place where he could get gifts but most of them either had too long a line or had nothing left. 

As he was looking around and trying to find anything that he could buy in the sea of people he saw someone trying to steal another person's wallet. Loki grabbed hold of the thief's hand which caught the attention of the person that was about to get his wallet taken. 

"What the f*ck?!" The man got angry at the person that almost took his wallet. As for the surrounding people they only took a few seconds to look at what happened and went back to doing their own business.

The man then called the police and as they were waiting for the police to arrive the man thanked Loki for catching the thief. He tried to give Loki some money but of course, Loki declined to receive the money, no matter how much the man insisted. 

So as they waited for the cops to arrive, Loki and the man started talking about why they were out here suffering the endless waves of people. The man was looking for a toy that his daughter wanted. He thought that he had already bought it a few weeks ago, but then he learned that it was nothing more than a knockoff, so now he needed to go out and look for the toy or his daughter might think that she was on Santa's naughty list. 

Loki told the man about how he was in the hospital and that he had forgotten about Christmas. The two of them talked for a while before the cops arrived. After that Loki had gone around the city but still found nothing that he could give as a gift. 

Still, there were many trinkets and such that he could buy but he didn't want to buy some random crap for his siblings, so Loki continued searching. Along the way, Loki had seen many people in trouble so he decided to help.

Loki spotted an old lady wanting to cross the street so Loki helped her for a bit. He then saw a missing child crying, so Loki help him find his parents. Then there was the young woman being harassed. 

Many other incidents happened one after another which made looking for gifts pretty much impossible. As Loki saw the sun was setting he knew that he had no other choice but to ask for help. He was reluctant to do so at first since he didn't want to bother anyone during this kind of event as he knew that the people he knew should be with their families right now celebrating.

Loki called almost every person that was on his phone but none of them picked up, as they went into voicemail. Loki was in a dilemma as he saw the sun finally set and he got another message from his siblings who kept on asking where he was. Loki sighed as he replied that he was coming home now. 

Since the place he was at was near his house, Loki decided to walk there. While walking through the streets he saw many houses decorated in a colorful fashion and he could even smell the scent of good food all around. Loki then looked at his empty hands and sighed. 

'I could've at least bought some food and drinks...' Loki shook his head and sighed again. As he was getting near his house he could see that even his house was colorfully decorated with lights and an assortment of things. When he was at the door he could smell a delicious scent coming from the inside. 

"Where have you've been big brother?" Loki was greeted by a frowning Alisa and a hungry-looking Liam. 

"Sorry I forgot that it was Christmas today and didn't get anyone gifts. I tried to look for something to buy, but all the good stuff has already been taken." 

"What you just got out of the hospital and you tried to do all that?... Big brother, we're already old enough not to need presents, just us eating together is enough. Also, you already provide us with everything we need, and you took care of us when mom and dad..." 

Alisa was having a hard time finishing her sentence as she started to tear up a bit. Liam patted her back calming her down. She then smiled as she wiped away her tears. 

"Point is you've done everything for us, and we don't need some silly gifts to make us feel like a happy family. Just staying together and eating together is already a great gift." 

As Loki was about to respond somebody suddenly rang their doorbell. Loki opened the door and saw that it was Matsuri that arrived. 

"Hey I got your message, so I came here to save Christmas." Matsuri entered the house bringing gifts. 

"Hey guys sorry for barging in, your brother forgot that he left the presents he bought with me." 

Loki wanted to say something but then he heard the doorbell again and this time it was Harold and the former delinquent Luke. 

"My parents were away and I was sleeping in, so I got your message late, but here we are, we came to save your Christmas." Luke proudly declared, but then he saw Matsuri who was handing out presents to Alisa and Liam.

"I thought that you didn't have any gifts to give? So what's your girlfriend giving out over there?" When Matsuri heard what Harold said she couldn't help but blush, but then Loki responded. 

"I didn't know that she or any of you were coming, also she's not my girlfriend, she's just a friend." The moment Loki said those words Matsuri frowned and pinched his shoulders. 

"Huh, what was that for?" 

"Nothing, I just wanted to do it," Matsuri answered with a smile on her face. Loki was about to say something else but then the doorbell rang again. 

'What's going on today?' As Loki opened the door, he was surprised to see that the people he helped today had come and were in a huge group as well. 

"MERRY CHRISTMAS!" The group spoke in unison. 

"What's happening, how did you guys find my house?" 

"Oh, I really wanted to thank you for what you did for me so I tried asking around if anyone knew you. It turns out you helped a lot of people today and all of them wanted to repay you. As for how we found your house, well it seems like you're pretty famous in this neighborhood, seeing as you and your siblings became martial artists. So just asking around a little and they pointed us in the right direction." The man who was almost pickpocketed answered. 

"We also came here bringing gifts."

The huge group was invited into Loki's house and what started with Loki and his siblings having no presents whatsoever gained a ton in the end.. This just goes to show you that doing a good deed will always be reciprocated.
