FATE/Probability

Shirou now in the vision of the boy he saw suddenly noticed a difference. He was able to feel the whole body as if it was his own.

He tried moving his body but was unable to do so, hence he concluded that this was the same as all his other visions. He can just watch as an observer but can't participate in them.

Before he could ponder anything more he heard the priest say 

"Now I am about to remove your seals as you said. Be prepared, it might hurt a little."

The now confused shirou looked on as the man put his palm atop the command seals. Then his hands emitted a light yellow glow which shirou identified as mana but to his utter confusion was unable to feel or even sense.

 As he tried to sense the mana he felt the sensation of something pinching his skin. The priest removed his hand slowly as the boy on the inside stopped thinking.

The scream of budding magus went unheard by anyone except himself, shirou felt as if someone had torn off his hands from his wist bellow.

In his agony, he missed the small sadistic smirk playing on the priest`s lip. Enjoying the suffering of the boy the priest said 

"I have taken 2 of your command seals, now go outside and use the remaining one to order saber to dissolve your contract and you shall be free as you wished."

Slowly the agony faded away as shirou walked outside the church and was stunned. He saw Saber his dad's servant standing there draped in a yellow raincoat.

He watches as his body moves in front of her and said 

"I am done. Let's break this contract and you can go fight for your grail and I will go my way home."

She doesn't reply or show any emotion on her face as she said 

"Are you sure this is what you want to do shirou?"

Shirou is stunned as he hears his name from the sabre`s mouth but before he can contemplate the implications he is on the ground with his hands supporting him from falling flat. 

As he looked up he saw Sabre having drawn her sword and she must have swung it strongly enough that the air pressure must have thrown him off before the blade could have sliced apart his knees.

"If you choose to opt out of this then I respect that and am laying you go."

Under the gaze of dumbfounded shirou, as he couldn't even feel the sword, his body rises and says 

"Saber by the command seals I command you to break our contract!"

With this sentence, the last seal faded away from his outstretched hand and no remaining evidence of the seal's existence remained.

Leaving behind the still-standing woman he ran down the church towards what shirou guessed to be emiya residence.

While running he was covered by a shadow and looked up for the source, only to feel a cold sensation on his left shoulder.

Looking at the shadow`s source he discovers it`s a giant man with one of his eyes glowing red and a large mane of black hair fluttering in the wind.

He was hit by agony far greater than the process of losing command seals as he registered the absence of his left arm on his shoulder.

This time the internal screaming and the scream of Shirou's body get synced as he falls and rolls on the ground in pain. His shoulder bone was sticking out of the wound and the jagged appearance of the cut leaked a profuse amount of blood making the street red with blood.

While rolling in pain shirou hears a voice 

"Bersker! Break his legs so that Onichan can`t run away."

Hearing this in the sweet voice of a young girl but being unable to identify the source chills the boy to his bones and then he loses the sensation of his legs.

His legs were turned the wrong way and apeared as if he sitting in Seiza but the wrong way. Then with another strike, the charcoal black-skinned giant wearing only an ancient Greek skirt flattened the boy`s legs, turning them into splatters.

Opening his blood-stained eyes, in his red-tinted vision shirou looks at a red piece of flesh lying on the road. When shirou identified the piece as his own lungs his hazy vision was covered by a pair of small feet and a purple overcoat.

Trying to crawl away with his only functional hand he hears a soft chanting sound and then his vision is covered by a white flash.

After the flash faded he still felt the agony of his broken body but his mind fog cleared up making him experience the pain more vividly. 

As he crawled he was picked up by the man and his body said 

"I am no longer a master, I don't have any seals so why involve me in this sick game of yours."

As he looked at the little girl wearing a purple overcoat and purple cap she stopped giving the boy a sense of relief that this would end but shattering his wishes she leaned near him making her snow-white hair shine in the moonlight.

Her mouth curved into a smile and her red eyes reflected curiosity as she said 

"What has got to do with me, I am here to meet my brother"

"Bersker lets take oniichan home!"

As the servant carried the shivering and broken body shirou felt the irony of the sweet words and the actions filled with malice as well as the angelic appearance and demonic behaviour of this girl.

The world started swirling shirou was carried by Berserker like a sack and his vision went blank.

….

Kiritsugu sat in the living room and was drinking a bottle of alcohol to drown away his sorrows. He thought 

Kiritsugu was pulled out of his self-pity but a muffled scream echoed in the house. Rushing to bed which he identified as the source kiritsugu slammed open the door.

Through the open door, he saw the blanket haphazardly thrown away and shirou rolling on the floor while holding his left wrist in a tite grip.

Rushing to the boy he closed the door and activated the bounded fields. He thought 

Kiritsugu put his son on his lap and started gently stroking the boy's head. He watched the sleeping shirou release the girp and the expression of pain eased.

As kiritsugu looked at the surprised expression of his son he started having a bad feeling. Trusting his instincts that have saved his lives multiple times he opened his damaged and weakened circuits.

He sat like this for some time at high alert until shirou released a bloodcurdling scream shaking even the battlefield veteran.

He watched with disbelief as shirou started sobbing and snot and tears started leaking from his face, soaking the yukata kirtsugu was wearing.

He watched with cold calculating eyes as Shirou`s body twitched all over and grunts left the boy`s throat making his boyish voice sound haunting and unsettling to anyone.

The magus killer thought 

Kiritsugu watched shirou the whole night even after his expression went back to normal. Wiping away the tears and snot from the boy he took him to the bathroom to wash him and changed his urine-stained pants.

Looking at his now clean son tucked inside the bed kiritsugu noticed a section of matress coloured red.

Checking it out he found that Shirou`s left forearm was bleeding and 4 small paper cutter blades were sticking out of his flesh.

This horrified Kisritsugu as he rushed into the shed carrying shirou. There laying the boy on a table he passed mana through the child`s body.

Even after repeated verification, kiritsugu was confused as to how these blades seemed to grow out of some muscle tissues just below the skin and have grown outwards till their current position.

After various tests, kiritsugu decided to pull out the blades from his son`s flesh and apply the medicine he made that he bought for the off chance of shirou getting injured during training or sparing.
