Fantasy Assassin in a modern world

"Sir, do you mean I have inner energy? How is that possible, my siblings and I have been tested like everyone else and back then we were told that we had no talent to become martial artists." 

Loki was now genuinely shocked and curious. He was someone who frequently checks the state of his body, and he had never found this so called inner energy inside his body. 

'Did it suddenly manifest itself, or did being injected by that kid's inner energy awakened this body's inner energy, or is it possible that because it was so minuscule that I could no detect it and the previous Loki already had inner energy... Then why did the result come back as negative, did someone mess with the test?' 

Many questions swirled in Loki's head, he wasn't the only one confused even Matsuri and the men behind Ryuuji were rather surprised by what was said. 

"Inner energy, Ki, spiritual energy, no matter what it's called it's something that even with our current knowledge and technology we can not completely understand. There are still many mysteries regarding how it is first formed in the human body. Some people think that only people who come from martial arts families could gain inner energy. Some think that with the right amount of training anyone could form inner energy. I'm not sure what the truth is, but right now all I know is that you have a minuscule amount of inner energy within your body. It is entirely possible that when you got hit by someone else's inner energy that caused some kind of reaction within you, resulting in your current situation." 

Hearing the old man Ryuuji's explanation everyone was somehow convinced, except for Loki. Loki had a lot of doubts but he wasn't that bothered for too long. He was an assassin, not some kind of scholar that could understand such topics. The most he knew about science was about human anatomy since he needed that knowledge to do his job. 

"Thank you for your guidance." 

Loki bowed his head, this time it wasn't an act as he was truly grateful to the old man. Ryuuji's lips curled upward a bit, while his son Kazuki continued to frown at the back. 

"There's no need to bow your head, this is simply fate."

After saying a few more words Ryuuji and those with him entered the school premises. Tang Ao and his men followed behind Ryuuji and his entourage. Only Matsuri and Loki were left behind the school gates. 

"So how about telling me the real reason why you called me." 

"To tell you the truth one of the students here had an encounter with that assassin in the urban legend." 

"You mean Fade?" 

"Yeah, so I was going to ask him some questions, but seeing the situation now I might not get the chance... Oh, wait, how about you go and ask him?"

"You want me to interrogate a student?" 

"No need to look at me like that, and don't say you're going to interrogate him you're just a curious librarian. You just need to ask him some questions about his encounter with that assassin, when you see him in the library." 

"You're overestimating the attraction the library has with the students. Do you know how many students visit the library? There's only one and that's my sister, she's the only student that ever visits the library." 

"Then how about talking to him in the cafeteria? Can you please do this for me?"

Matsuri bowed at a ninety-degree angle. Loki looked at Matsuri and scratched his head. He didn't want this very tenacious lady asking questions. 

'I'll just give her false information later. Hmm, but what if she asks the kid questions herself later on. I don't need such loose ends, maybe I should really talk to the kid and make it seem like I truly tried.' 

"Fine, I'll do it. Who's the student I'm supposed to ask?" Matsuri stood upright and smiled brightly at Loki. She then took a picture from her pocket and handed it to Loki.

"The student's name is Michael Rosales, a student from the martial arts course." 

"Alright, I'll try asking him about Fade. I don't really know if he's going to talk to me, but I'll try my best." Hearing Loki's answer, Matsuri suddenly kissed Loki on the cheeks. 

"Thank you, you're the best." Loki touched his cheek and looked at Matsuri weirdly. 

"That's sexual harassment you know." 

"What you're actually complaining that such a pretty girl kissed you. Do you know how many people would line up to get a kiss from me?" 

"Really? Those people must've been blind or crazy... Whatever I need to get back." 

"Why don't you just come with me and let's get something to eat instead." 

"Maybe next time, I really do need to get back."

"I thought you said that no one ever goes to the library, so why are you so eager to return?" 

"Unlike you, I do my job properly."

"Huh, I do my job properly more so than the other officers that just sit on their chairs doing nothing!" 

"Yeah, yeah. See you next time, Detective." Loki didn't bother to listen to Matsuri's reply and left while waving his hands. 

...

While Loki and Matsuri were talking, Ryuuji was in the Principal's office sitting on the Principal's chair facing Michael. Ryuuji was about to bow his head but before he could do so his son Kazuki stopped him. 

"Father, what do you think you're doing? You're the head of the Mutou Clan, you cannot bow your head to anybody." 

"Why shouldn't I bow my head, huh? My grandson had done something wrong, so I need to apologize, and so do you. I had failed to educate my own son to teach my grandson how to act like a respectable human being, and you had failed to teach your own son how to behave. So the two of us need to bow. So shut up and bow your head!" 

Ryuuji used a bit of his inner energy to release a sound wave targeting his son. Kazuki stepped back a bit and started bleeding from the mouth. He wiped away the blood on his lips, gritted his teeth looked at the confused Michael and bowed his head reluctantly. Seeing his son finally doing as he said Ryuuji bowed his head as well. 

"I'm sorry for what my grandson did, and I'm sorry for the actions of my son as well."
