Fantasy Assassin in a modern world

Once they got home Kazuki left his father and went to his side of the Mutou Clan's estate. The Mutou Clan owns a large piece of land that encompasses eleven hectares. The main house was located in the middle and the surrounding houses near it are people from the main family line, and the outer perimeter is for the branch families. 

The entire estate was based on the foot of a mountain making it look truly mystical. People who had arrived here for the first time would think that they had been transported into another world.

Kazuki's residence was located in front of the main house were his father the patriarch of the clan lives. Unlike the main house, Kazuki's residence had a grand look to it and was the largest among all the residences of the Mutou Clan. It was double the size of the main house. The reason for this was because the main house needed to be of a precise size for a magical barrier that their ancestors created to work. This barrier was rumored to be able to withstand numerous missile attacks. It was one of the reasons the Mutou Clan was able to remain mighty despite the growing power of modern weapons.

The other reason for Kazuki's residence being larger was because of his vanity. The second mansion had always been used by the appointed heir of the Patriarch and it was indeed smaller than the main house before. Yet after staying as the honorary heir for so long Kazuki did not like the look of the house and requested to remodel it. 

...

Mutou Kazuki was someone with high pride but his talent as a martial artist was inferior to his father and his son, as even after all these years he had been stuck in the level of a Captain. He was also someone who was extremely sinister and vengeful. He was the complete opposite of his father who was an honorable and forgiving man. 

The reason for this personality of his was because he was born with a silver spoon in his mouth, and didn't have any setbacks growing up. Yet the biggest contributor to Kazuki's arrogance was his deceased mother, who taught him at a young age that their clan was a noble one and those that don't practice martial arts were an inferior race of humanity. 

...

Kazuki entered his abode where numerous servants waited for him at the front door and bowed, his wife Kotori approached him looking worried. 

"Dear, so what happened were you able to punish the brat that hurt our son? Are we going to fight with the Mugami Clan?" 

When Kazuki heard what his wife said he wanted to punch her, but held it in. He could not just beat up his wife, since his father would probably disown him if he did that. Holding back his anger, Kazuki tried to speak in a neutral tone. 

"If you want to know what happened, go and ask one of the men that came with us. I'm going to the training room, do not disturb me." 

When Kotori heard what Kazuki said she knew that something unexpected had occurred. She no longer bothered her husband since she understood his temperament. She knew that her husband should be fuming and wanted to attack her since she brought up the topic he wanted to avoid discussing. 

Kotori nodded her head and left to ask the guards about what happened. Kazuki sighed as he watched Kotori leave without saying a word. Kazuki felt that this wife of his truly understood him. Even though their marriage was an arranged marriage, it would seem that his Kotori truly loved him. The moment Kazuki had these thoughts he shook his head and headed to the training room. 

...

Mikado Kira was in his room smiling, he had heard from his subordinates about the events that transpired the night prior. Kira tapped on his desk looking amused. 

'It would seem that something quite interesting has happened. To think that Mutou Hayate had finally made a move, but he didn't target me and instead targeted that meathead Shin. The Mutou Clan is a Clan that even my Mikado Clan needs to pay attention to, and the meathead's clan is also of the same level, so they shouldn't be too afraid of my clan... Is that senior perhaps afraid of me?'

The moment that thought came to mind Kira could not help but smile. He was a person who treated everything as a game to be won, and he was happy knowing the game he was playing was finally moving forward. He had already planned to assert his dominance by beating Hayate, then going for Shin, but now he only needed to deal with Shin. 

'Should I thank Hayate for making the first move?... It doesn't matter, since this is all but a game that I have already won. It was just a matter of time... Still, what's even more interesting is that guy called Fade. Even using the entirety of the Mikado Clan's resources I could not find a single trace of him. An assassin of this level could prove a worthy playmate for me.'

Kira wasn't really that bothered by Fade and was only slightly interested in him. As long as Fade didn't bother him he would not bother Fade. 

'Hmm, now that things are going my way, should I focus on pursuing Alisa? She is one of the few challenges that I find truly amusing. She isn't affected by my looks, my status nor my money, her family circumstances, as well as their hidden enemies, are also quite enticing. She's the only one aside from the meathead that has always been true to her words. It is quite a treat to see that cold expression of hers. Still, I wonder what she would think once she finds out I'm not her true enemy.' 

Kira then looked at the files on his table. There was a picture of Hayate, Ryuuji, and Kazuki from the Mutou Clan, there was also a picture of Shin and his father, Detective Matsuri and Captain Tang Ao. Then finally there was a thick file for Alisa and her family. 

"There are so many players and pieces now, the game is becoming even more interesting."
