Fate/Stay Night Unlimited Blade Works:Son of Kotomine

The bastard' just desserts and Caster's first mistake

Y/N Pov

After me and Rider talked again and Shirou and Rin getting in the way of that,we went back to the Tohsaka mansion where I to play dump about knowing Rider and knowing who her master is. After that was said I made my way over to my room where I walked past Archer and when I walked past him he looked like he was looking at an old freind , maybe I reminded him of someone he knew in life. With that he went into spirital form to escort Shirou home and I went to bed. It is now morning

When I went to school I heard that Ayako was found in a back alley last night and I knew what that meant, was I mad at Rider no because the fault in this falls on one person Shinji(BASTARD) luckily Ayako was still alive but I heard that little piece of shit talking about as if to brag. I lost it

I walked over the bastard as he was talking about what happened to Ayako with Shirou and punched him across the room,I walked over to him as he lay on ground like the worm he his, and I did what most people do when they see bugs on the ground.Stump them out. and so I did I kicked him chest,face and groin. After that I got on top of him and started smashing his face in. At this point multple people were screaming and yell for me to stop but I don't listen to mongrels. Shirou tried to get me off the bastard but I wanted him to pay for everything he did to Sakura! For the people he made Rider hurt! And finial for making Rider do his dirty work!

Sakura & Shirou:Please STOP Y/N!

My fist stops just short of the bastard's blooded face, Shirou then lets go of me and as I get up and pick up Shinji(BASTARD) and tell him that he's safe from me

Y/N:"Whispering"I know your secret,false master of Rider."with that I drop him to the ground and look at Shirou and signal him to follow me

After I clean the blood off my hands and some that got on my face, me and Shirou walk into an empty room and lock the door.

Shirou:Y/N what the hell was that!?

Y/N:First,Shinji is the false master of Rider and has been making her attack people including Ayako, he also plans to attacking the school as whole with that bounded field.Second, I coundn't take him braging about all he's done when he made Rider do his dirty work.Third, Rider is actually a good person and dosen't want to hurt innocent people and hates Shinji(BASTARD) for making her do these things.

Shirou:Okay but how do you know all this and why didn't you me or Tohasak yesterday?

Y/N:I met Rider a few days ago and we talked and she told me,we made a deal that when Shinji(BASTARD)attacked the school she would betray him and become my servant. And the reason I didn't bring this up yesterday was because I didn't want Rin's plan to get in my way, don't get me wrong she has a great plan but I already have mine soon... yeah

Shirou:Okay but why did you-

Y/N:Beat Shinji(BASTARD) into a bloody pulp,come on Shirou we both know what he does Sakura and how he acts towards women in general, then he has the guts to bring a beautiful woman like Rider down to his disgusting level by having her hurt people, and now he's hurt innocent people. Shirou you know I can't stand mongrels like him. And second why are you getting so upset you seen me me ki- actually heres not the place to bring that up.

Shirou:Alright you have a point, but please don't-

Y/N:Don't what?

Shirou:Don't let your emetions and belifes walk you down a dark path.

Y/N:What are you on about? Come on it's all most lunch time."With that I walk out

Shirou Pov

After me and Y/N had that talk I remembered what Archer said last night,

Flashback Archer: Keep an eye on that freind of yours because soon he'll start walking down a dark path and he'll need your help to bring him out of that darkness.

I don't know why Archer said that. I mean sure when it came to people Y/N really hated he would be crude,cruel and mean but that's not who he really is because at his core he's a nice guy who loves and cares for the people close to him, he even told me when we we're kids that he would do anything to procect the people he cared about. It's clear he still means that, he came to help me when Lancer attacked,he helped me after I was injured after meeting Berserker and he saved me when Tohsaka attacked me yesterday. And he would always protect Sakura when she would get bullyed, and sure he could be violent and there have been times he went to far he was still my best friend.

Shirou:Well even if what he did the Shinji(Bastard)was a bit out of line he's still my best friend"And with that I make my to the cafatera and after school ended me,Y/n and Tohsaka were looking for the spots where the bounded field may be set up, I decided not to tell Tohsaka about what Y/N said about Rider.

Y/N Pov

After finding most the spots where the bounded field was set up,firstly I think Rin may actually like Shirou and seconed,me,Shirou and Rin all went home with me going to Shirou's house, I watched as he trained with Saber in sword combat even getting involved with training him a bit and then I had some food with me and Saber still seeing who could eat more and I was about to get ready to go to sleep when..

Artoria(Saber):Y/N wake up caster has taken Shirou!

Hearing those words with out second to waist I get into my cloths,grabed my black keys and me and Saber took off in the direction where Saber senced mana, and on our way there the only thing I could think about was that this Caster just made the biggest mistake of their afterlife. we made it to ryuudou temple after getting through the bounded field, and as we're making it up the stairs we see a man with a long katana most likely a servant.

Artoria(Saber):If I may ask what class of servant are you?

Sasaki:I am Sasaki Kojiro, Assassin class servant.It is only natrual to name one's self before combat.

Artoria(Saber):Then as a knight I am honor bound to do the same, but once I have you must withdraw. My name is-

Sasaki:No matter"he starts walking foward as he pulls out his katana, as I draw out six black keys,

Sasaki:My blade will tell me all that I need to know of my enemy. If you wish to pass through here then you must force your way in.

Y/N:I accept that challenge."I say as my eyes briefly spark with lightning
