Fantasy Assassin in a modern world

Michael arrived in the library and saw that Shin was still there and felt rather disappointed. He wanted to ask Loki more about mana and spells, but now that Shin was here he could not do that. Noticing his disappointed expression Shin started to wonder what kind of relationship Michael and Loki had. 

"Hey, buddy what brings you here?" Shin smiled as he approached Michael. 

"Oh, I just wanted to ask Sir Loki about some books I read." 

"That's cool, so what kind of books are you reading now?" 

"... I'm actually trying to learn more about the occult." 

"The occult so spirits, magic, and those kinds of things, right?" 

"Yeah, I thought since I couldn't get stronger in martial arts the normal way I'll find other ways to improve."

Michael got excited talking about it when he suddenly realized his mistake. No one his age would even talk to him in this school, so having a conversation with Shin was refreshing. Michael lowered his head embarrassed. 

"I bet you think I'm crazy for doing this..." 

"Not at all, I respect you for looking for other ways to get stronger. Who's to say you might actually become some sort of wizard. If you do get powerful using your method I hope to have a fair match against you someday."

Shin smiled as he patted Michael on the shoulder. When Michael heard what Shin said he looked at him dumbfounded and then after a short pause he almost teared up but held it in, he then nodded his head and responded. 

"Sure." The two then started to have their own conversation while Loki was watching on the sidelines. 

'I guess the guy isn't all that bad.' 

...

Alisa arrived in the library and was surprised to see that his brother was accompanied by two other students both of which were famous first years. One was the strongest first-year Mugami Shin and the other was the weakest first-year Michael Rosales. It was rumored that the two were friends but it was still surprising to see them together, not to mention with her brother. 

"Alisa you're here, just wait minute, I'll be done in a moment." 

"Alright."

Alisa nodded her head in response as she sat in the nearby chair. While she was waiting she noticed the two freshmen were staring at her. It wasn't unusual for her to be stared at due to her looks, but this felt different. As she was wondering why they were looking at her Shin suddenly approached her. 

"Hey, are you Sir Loki's sister?" 

"Yes, I am."

"Hi, I'm Mugami Shin a freshman."

Shin extended his hand forward with the best smile he could muster. When Alisa saw this she was quite surprised. She had heard the rumors about the delinquent Shin who loved fighting more than anything, but now that she was face to face with the person it would seem that rumors were as usual an exaggeration. This kid wasn't didn't look like some kind of mad dog, that would bite anyone who spoke to him. Alisa happily took Shin's hand and shook it. 

"It's nice to meet you, I'm Alisa Matsuda, the librarian Loki Matsuda's little sister." 

"Oh right, this guy is my friend Michael Rosales." Shin pushed Michael forward. 

"Hello," Alisa smiled as she saw the rather shy Michael. 

"... Ummm... Hello, I'm Michael... Sir Loki has helped me a lot... Umm... It's nice to meet you." Michael could not help but lower his head as he spoke to Alisa. He felt nervous as this was the first time he spoke to a girl as beautiful as Alisa. Seeing how nervous he was made Alisa giggle. 

"It's nice to meet you as well, Michael." 

As the three students were getting along another person entered the library. When Alisa saw the newcomer her smile turned into a frown. 

"Hello everyone, hmmm, why isn't this an unusual group of people to have gathered." The newcomer was the ever-smiling Kira who was accompanied by two subordinates. 

"What are you doing here, Kira?" Alisa's voice sounded like a grow as she spoke. 

"Why I was going to look at some books, of course, this is a library, correct?" Kira answered while shrugging his shoulders. "Oh, if it isn't the heir of the Mugami Clan, little Shin-kun how long has it been since we last saw each other, a year or two?" 

"It's been five years, Kira-nii-san," Shin answered almost indifferently which was surprising coming from him. 

"Has it been that long? That's rather surprising seeing as we are going to the same school? Well, anyway, I heard that you have been challenging all the powerful martial artists in the area, I wonder why haven't you come to challenge me?" 

"... It's pointless to have a battle with you. That spar we had five years ago has made it clear that I gain nothing fighting you." 

"Is that so... That's rather disappointing, well if you ever change your mind, you can find me anytime." After saying that Kira shifted his attention and looked at Michael who was standing behind Shin. 

"This should be the first time meeting, I'm Watanabe Kira, it's a pleasure to meet you." 

"... Michael Rosales, it's pleasure as well." 

While the group of students was talking to each other the school bell rang again, this was the final bell signaling that everyone in the school should leave the premises. 

"Oh look at the time, it's already so late. Hey, I know that this might sound a bit forward, but I feel comfortable with you guys. So since we're all together how about we go out for dinner my treat of course. What do you guys say?" 

"Huh, why would I have dinner with you?" Alisa asked while frowning. Kira didn't respond to Alisa and instead looked at Loki. 

"What do you think Sir Loki?" 

Loki who was silent this entire time stared at Kira. After a moment of silence, Loki finally responded. 

"Sorry, but I can't have a student treating me to a meal." When Alisa heard what Loki said she smiled and was about to taunt Kira, but then she stopped when she heard what her brother said next. 

"So instead of you treating me, allow me to treat you guys to a meal."

"Oh, if that's what you want, thank you in advance," Kira responded while looking at Loki with curiosity. 

"How about you two are you coming as well." 

"How can I refuse an invitation from Sir Loki," Shin responded. 

"... I'll come as well," Michael responded. 

"Okay then, I'll just call my little brother over to the gate, and we'll be off."
