(? POV)
...what?
I feel like I'm floating. Where was I before this? I was... walking on the street and a car swerved off the road. No that's not right. I... went in front of it. Why? A person, they pushed me? No I pushed them. I was their brother. What was their name? I can't remember. What was my name? I can't remember either. What happened next? I was hit by the car and crashed through a window into a store? Yes a store. I knocked over a table then crashed into a mirror, there were glass shards everywhere in my body. Did it hurt? I don't recall. What then... I woke up here? No I missed something. Yes, it was a card. A tarot card flew off the table I crashed into and landed in front of me. It was a picture of a man hanging himself by his foot with a glow around his head. It was the Hanged Man. There was also Michael Jackson's Man In The Mirror playing in the store. Then I died, I think I died. Where is this? The afterlife? Oh, a light is here now. It is swallowing me, it feels warm. I feel tired, I'll just rest my eyes for a while.
(3rd Person POV)
The Tohsaka household was in distress. After awakening Sakura's magic circuits she had a fever. Her sister Rin didn't have such problems and they checked Sakura's magic circuits and found that everything was healthy. She even had the same level of od as her sister. Perhaps it was just a regular fever or so they thought. Meanwhile in a mirror next to the bed Sakura lies in was a boy. They were covered in bandages with glass shards sticking out of his head. Covering the bandages was a black leotard and white gloves. A black and white hood covered his head. No one could see them for they are a stand and only stand users can see stands. Who is the stand user of this stand you may ask? Why none other than Sakura Tohsaka herself. But this isn't just any stand, this stand has sentience.
"Where am I?" The boy in the mirror asked.
He couldn't remember much. He looked at himself and assumed it was the appearance he always had. He looked over and saw a girl with black hair and a red ribbon in it. Somehow he felt this connection with her, like she was someone very important to him. He could feel her emotions and how she was distressed. He wanted to reach out and hold them close. He tried to walk over to them but was stopped by an invisible wall. No it wasn't a wall, it was a mirror. Is he inside a mirror? He tried to push harder and he flew out of the mirror, past Sakura and into the window of the room at the speed of light. The stand was surprised at this and tried again. He flew into Sakura's eye, then the water of a flower vase and then back into the mirror. It seems that he can move between reflections at the speed of light but he wasn't trying to do that, he was trying to get out of the mirror. After an hour of trying it seems that he is unable to leave the mirror. The boy in the mirror became sad at not being able to comfort her. Sakura soon awakens and sees the stand.
"Excuse me, can you get me the water on the table and bring it to me please?" She asked thinking it was a member of her family and the appearance was just her hallucination.
The stand obeyed excited to help her. He jumped to the reflection in a vase next to the glass of water and paused. How was he supposed to move the glass? He can't leave the mirror. He tried to grab it anyway and he felt himself touch it. But how? He saw an uncoloured version of the glass appear in his hand, the reflection of the glass. Well he has the glass of water now. The boy moved over to Sakura and placed it in her hand. With that done he returned to the mirror.
"Thank you." Sakura said as she drank it and went back to sleep.
A week went by and Sakura recovered from her fever. She also realised that the boy in the mirror was real. That came as a big surprise but he seemed nice so Sakura let them be. They were very kind to her and played with her when Rin was being taught Magecraft by her parents. It was quite strange that no one else can see or hear them and so they think that she has an imaginary friend. But she knows that he is not imaginary and that he is very real.
(Flashback 2 days ago)
Sakura was playing with the kids at school when one of the boys kicked the ball into a bush. Sakura was asked to go get it so she went over to the bush and picked up the ball. As she turned away to walk back she noticed a snake in the bush and it jumped at her with its fangs open. Only to be cut into pieces before it even fully left the ground. In a bottle nearby was the stand with two blades protruding from their wrists.
(Flashback end.)
They told her that they were special to them and that they are only able to be a few hundred meters away from her at the most. Sakura didn't know who this was but if someone is important to someone else then they are family? She told them this and asked if she was family.
"I suppose I am... Then who am I to you?" He asked
Sakura thought hard. Someone that is a boy and protects them while not being their father is a brother right?
"Brother? Yes, Yes! Please call me Brother from now on."
So time passed and Sakura lived with Rin, father, mother, Brother and uncle Kariya who visits every now and then. This all changed when her father gave her to Zouken Matou. Tokiomi Tohsaka didn't want to have two children trained in his family's Magecraft as he thought that it would introduce competition. This is when Zouken came along and offered to adopt one of the children to be his family's heir as his own child was lacking the magic circuits to be a suitable heir to his Magecraft and Tokiomi accepted and eventually chose Sakura.
"Will mother and sister visit me?" Sakura asked.
"You should think that they never existed." Zouken replied.
"Now Sakura your 'education' begins immediately."
Zouken led her to the basement of the Matou mansion where a massive pit of worms writhed. These were the familiars of Zouken. You see, due to Zouken Matou's preferences, their education in their Magecraft is very... physical. It is memorised by the body rather than the mind and this process is extremely painful. Zouken grabbed Sakura and threw her into the pit and walked away. As she landed the worms tried to bury into her but were cut apart by an invisible blade. Brother was inside her eye and would not let any of the worms in sight near her.
"Quickly, let's get out of here." Said Brother.
Sakura climbed the stairs out of the basement. She ran for the front door only to stop at seeing Zouken who was already there.
"Now where are you going? We haven't finished your education." Zouken knew his crest worms were destroyed and he was curious to how she did it.
Sakura looked at Zouken and he found that his legs had been cut off. Sakura gasped and stumbled back. Did Brother really cut off his legs? The legs turned into worms and rebuilt themselves back into legs. Zouken raised his hands and bindings appeared on Sakura including a blindfold.
"It seems you have mystic eyes. This is good. As my future vessel, it will be interesting to have mystic eyes."
Zouken dragged Sakura back into the basement and put them back into the worm pit. Without any reflections, Brother was unable to help her escape. The worms burrowed into every part of her body causing her to scream out in pain. This continued throughout the night and Brother was angry at Zouken for doing this to Sakura and most of all he was angry at his powerlessness.
Kariya arrived at the Tohsaka household three days later to visit them. He knocked on the door and it opened to reveal a woman.
"Hello Aoi, how are you today?" Greeted Kariya.
"Oh Kariya. Please come in." Aoi invited him inside.
"Uncle Kariya!" Said an excited child as they ran up to Kariya. Rin Tohsaka, daughter of Tokiomi and Aoi. Energetic and prideful.
They continued to converse and play with Rin but eventually Kariya noticed that Sakura wasn't around. While she was shy he usually saw her every time he came over and so he asked Aoi where she was. Upon hearing Aoi's answer he immediately left the manor to go to the Matou mansion. Magi keep their Magecraft to themselves so Aoi didn't question what the Matou's Magecraft was but Kariya knew what happens in the mansion because he was a Matou himself and ran away upon learning what their 'education' really was. Kariya Matou confronted Zouken Matou and made a deal. He would win the holy grail war for Zouken and Sakura would be free to return to the Tohsaka household. Zouken decided to humour them. He didn't except the runaway to win but they might surprise him. He wouldn't lose anything if he fails and if he succeeded then he would not need Sakura anymore. The holy grail war will start in one year and Kariya will have lots of 'training' to catch up on. However Zouken will not stop Sakura's training. In a metal doorknob was Brother who heard everything. He jumped back to Sakura to inform them of this.
Sakura lied in bed after another night of education. After three days of torture, her body was starting to change. Her hair and eyes were changing colour. Her black hair had shades of violet and her eyes have a small pigment of violet.
"Sakura, Kariya made a deal with that monster to free you." Brother started explaining.
"Uncle?"
"Yes he has to win something called the holy grail war for your freedom."
"Why would he do that? He doesn't want me. Father didn't want me." Sakura was already resigned to her fate and Brother could feel it.
"I want you. You are worth saving."
Brother grabbed Sakura's reflection and pulled. Sakura faded from the real world and her uncoloured reflection became coloured as she was pulled into the mirror world. Sakura cried into her only emotional pillar's arms and soon fell asleep. This mirror world is isolated from the outside world and only contains what was reflected when Brother pulls something in. Since he pulled them in through the doorknob, only the room exists so Brother can't use this ability to escape with his sister. He can jump between the reflections and leave what he pulled in trapped. As Sakura and her brother laid together in this hell of a mansion, Sakura found comfort.

What do you think? There will be a Time-skip to the fourth grail war so be prepared for that. To answer some people's questions of could Brother use Man In The Mirror's ability to pull Sakura into the mirror and leave behind the worms in her body? Yes they could do that but they don't know that. Some stand users have their stand for years before they realise what they can do with their stand. Take for example Joskue from Diamond is Unbreakable, he eventually discovered that his dried blood counted as an object that is not part of his body.
Philosophy: purpose
When I was writing this. I was thinking about light. You could consider people as lights. All different colours showing how unique everyone is. Some shine brighter than others their whole life and some only need just one opportunity to shine brighter than anybody. Some lights guide the way and prevent you from getting lost, these could be people that help you on your journey of life like mentors. Some lights provide warmth like a fire, they could be someone's loved ones or the stranger that helps you out of the kindness of their heart. Every light has a purpose so don't think that you are useless. You just need a moment to shine.
