Treasure in orphanage.

"Oh? Zouken?"

Although I haven't interacted much with him, he is still the reason for all my pain for 10 years. 

I have something like a personal grudge against him. In original timeline, Sakura would have been the one to suffer. Looks like I have to take out revenge of two persons on him. 

While I was thinking what to do with him, he felt cold on his back. Zouken was a person who would die to live forever... Yeah, that doesn't make sense at all.

Feeling even a little danger on his life, he immediately started to run by turning into insects.

"Where are you going?" I immediately traced along the nearest death line.

"Wait... what?" It seem that I forgot that my body is of a kid. Even my limbs are smaller than normal. 

I was unable to properly trace against the line.

Since I wasn't able to trace on the death line, Zouken was nearly successful in escaping. 

"If I can't kill you right now, then..." I activated vision of death and traced along the line with my eyes. Even though it won't kill him, he would atleast be seriously injured.

"Aaahh!!" Before he disappeared, through insects, he let out a painful scream loud enough to reverberate all around the room. 

"Tch... I should have blocked the space first. I really forgot to use true magic."

After cleaning myself, I exited the room. Almost all of matou mansion was empty. There weren't many servants either.

From what I could sense, there was a person in upper floors. 

After waking upstairs, I met with another blue haired person. 

"Ah, right. You were also here." 

Standing in front of me was byakuya matou. Father of Shinji.

"What? What are you doing here?!" He exclaimed on seeing me.

"Well... Long story short, you have to die." I said.

"What-" 

This time I used true magic first and properly killed him using death points. His whole body, every single atom of his body, disappeared into nothingness.

"Now, what shall I do?" I sighed.

I can't really go back to tohsaka family after they just gave me away. I don't really know anything else about fate series before fifth holy grail war...

"Let's see...  I am a kid so I must be enrolled in a school?" That sounds so stupid but it also makes sense. 

I mean I already have graduate level studies completed. I don't really need to go to school.

-Ding!

[Mission #2

- Visit arin orphanage and stay for 1 hour.

- Reward: 100% shares of Shinomiya group.]

HUH?

System screen popped in front of me all of the sudden and startled me, but it's content was even more disturbing.

Just for visiting an orphanage, I will get 100% shares of Shinomiya group? Shinomiya group's net worth is more than 200 trillion. Is there some kind of divine weapon hidden there?

...

A few hours later...

There really is a divine weapon here?!!

Since matou family is a rich family, it's influence in fuyuki city is also not low. I was easily able to get access into this orphanage.

But wait... She wasn't supposed to be an orphan right? I don't really have any proper memories about it but she did have a mother in original anime right?

Then why is she in a orphanage?

Standing in front of a chess board, I saw a silver haired small girl fiddling with the pieces. 

"Shiro, introduce youself. This is Aisiwon Makiri. He is here to visit the orphanage." One of the staff in orphanage came forward.

"..."

As expected, she didn't say anything.

"Do you know how to play?" I asked her while looking at the chess board.

"...mmh" she slowly nodded her head.

"Great. Then would you like to play with me for a bit?"

I said while taking the seat opposite of her. Since my pieces were white I started first with pawn to E4.

She replied with pawn to H5.

...

After a few moves, it was checkmate. I lost.

Hmm... Using computer moves against her won't work. 

[Learned skill : Chess (Advanced)]

Just playing once with her moved my chess skill to advanced level. 

"Let's start again."  I said while rearranging my pieces.

"..." She didn't reply but started arranging her pieces. 

This time she started with pawn to B4.

...

After a few dozen games, I finally won against her once. Though that was only a fluke, I had just used tactic to barely win against her. 

[Your chess skills have broken through the limit of Max and reached the realm of God.]

After having reached realm of God in chess, I can finally clearly tell. This girl in front of me is a real treasure. Even now, her skill are rapidly increasing almost near to the realm of God.

"Shiro, would you like to come with me?"

Hearing me, she tilted her head in confusion.

"Would you like to stay at my house as my sister?" I asked her while extending my hand towards her.

After a while, she slowly moved her hand and held my hand.

"Great!" I said with a smile.

...

After some paperwork, and registration from makiri family (I was the only one in making family.), Shiro was successfully adopted in Makiri family.
