Fantasy Assassin in a modern world

After some time Alisa was finally able to teach Loki the basics of how to use his smartphone. So now Loki was walking through the streets while looking at his phone. He was rather impressed by how advanced this civilization without mana was.

'Though in that world no one would really need this thing. Most of its functions can be replicated with spells. Hmmm, I guess having mana did hinder the progress of that world's technology. Still, mana was extremely convenient you could practically do anything with it.'

While Loki was reminiscing about his old world, he looked around in this new one. This world was filled to the brim with lights. It was like the very stars themselves were illuminating the streets. Even though there was still fighting in this world, it was overall, mostly peaceful.

'If only Shera was born in this world, she wouldn't have needed to do those things. She would've been a student in this world, playing with friends, and living her life to the fullest...' As he started to think about such a possibility, Loki shook his head to cast away the feelings that were once again starting to build up within him.

Loki tried to distract himself by thinking about something else as he continued towards his destination. He found that though his new body looked weak it wasn't actually that bad. At least it felt like the previous owner used to do some minor exercises to stay healthy.

'Well, it doesn't really matter, if I'm weak now I just need to train. Also, there's the problem with mana. The mana in this world is too weak, it's there but barely. I won't be able to regain my former strength without mana, still, I need to have at least the minimum amount of strength to be able to use some of my old techniques.'

...

Loki was nearing the arcade when he noticed something going on in an alleyway near the arcade. He looked at it and saw someone being beaten up, and upon closer inspection that someone was none other than his new younger brother.

When Loki saw Liam being beaten up he was reminded of that time with Shera. Even though he wasn't his true brother but the brother of the previous body's owner, Loki still felt angered.

...

The four young men who were beating up Liam stopped as they felt a spine-tingling chill. As they were wondering what that was, someone suddenly spoke to them.

"What do you think you're doing?" The four of them quickly turn around to look at the newcomer, when they saw that it was just one weak looking guy they felt relieved. For a moment there they thought that a police officer had shown up.

Liam who was barely conscious thought he heard his brother's voice but immediately dismissed the idea. In his mind, there was no way his cowardly brother would be there.

"Hey man, just walk away."

"Yeah, don't try to be a hero." The four young men tried to intimidate Loki, but of course, Loki wasn't someone that could be intimidated by some thugs. He approached the four without saying a word.

"We gave you a chance but you just had to play the hero." One of the four suddenly charged at Loki and punched forward. Loki evaded the punch and used the [Enhancement] spell on his right arm and delivered a perfect counter to the young man's chin.

Getting hit at the chin the young man fell on his butt, his sight becoming a bit blurry as he was getting dizzy. When Loki saw that even with using [Enhancement] and attacking at the right angle with a perfect counter he wasn't able to knock out a person he felt a bit frustrated. Still, before the young man got his bearings back, Loki immediately kicked him, and this time the young man fainted.

'So this is the level this body is at.' Loki sighed as he felt his right hand aching a bit. On the other hand, the remaining three young men looked at Loki in surprise. They didn't expect that someone so meek-looking was actually a good fighter.

This time when they saw Loki approaching them, the three started to panic. Two of three young men suddenly rushed towards Loki. One of them did a kick while the other punched while charging forward. Loki evaded the punch and used the momentum of the guy kicking and pushed him towards the other guy. Loki then quickly followed up by using [Enhancement] on his left arm and initiated a punch to the gut to the one who was imbalanced by the kick.

The two fell to the ground clutching their abdomens in pain. Loki felt both of his hands were now hurting. Still, he continued to show a stoic expression as he slowly approached the last of the four.

"Stay the f*ck away from me!" The last of the four young men took out a small knife. When Loki saw him take out a weapon, something changed.

The young man who took out the knife saw Loki's gaze and felt something frightening, His body started to tremble as he fell to his knees. The young man couldn't understand what was happening but he felt like something was suffocating him. It was getting harder and harder for him to breathe it was as if someone was choking him. Loki used this opportunity to kick the young man until he finally passed out.

'He couldn't even handle that little bit of killing intent?' Loki shrugged his shoulders as he then shifted his attention to his little brother. When Loki saw the bruises on Liam's body he once again looked at the four who had fainted.

'Should I kill them?' While Loki was deliberating what he should do next, he heard someone's voice.

"It was here officer. Some thugs were beating up a kid over here!"

'Officer? A guard?' Loki was quick to act as he carried Liam on his back and left the scene. He didn't run and simply blended into the crowd of people at the other end of the alleyway. Even though he was carrying someone on his back and was supposed to be someone that you would notice immediately no one seemed to care. This was because Loki was able to weave through the crowd while passing through their blindspots. It's a trick he learned back in his old world. To pass through crowded places like a ghost. Even in this body he could perform a bit of those movements.
