Night was just about to fall as Shirou walked into the nearby convenience store. He resolved to make dinner tonight if only to keep his mind off of the day. It had started great and hopeful with a beautiful play he got to see with Elena.

But meeting her father had left a sour taste in his mouth. Shirou always tried to see the best in others. But in this scenario, meet him he couldn't let go of this sick feeling in his stomach. The man had compared the mass killing of Magi to calling an exterminator to an infestation. Even recalling those words made Shirou sick.

He couldn't even properly focus on shopping, feeling too disturbed by what he had just heard.

"Big brother!"

His train of thought was broken by a surprise Illya wrapping her hands around him and hugging him. Shirou looked at her and also saw Taiga walking his way.

"Shirou why are you here? Ooh are you making dinner tonight?" she asked excitedly.

"Yeah Fuji-nee, I'm making dinner tonight. I need to get my mind off of some things" Shirou admitted.

"Something wrong big brother?" Illya asked worriedly.

"No it's just….it's been a long day and I just want to do something productive" he said. It wasn't a lie. He was just kind of through with this entire day, his entire meeting with Manadek had been more draining then he had imagined.

Getting the necessary ingredients for tonight's dinner in hand, the three walked out of the store and began to walk down the street to the Emiya residence. As they turned the corner they stopped before bumping into someone.

"Oh…hello Shirou…" a soft familiar voice spoke.

It was Sakura. She smiled at him and it made him crack a smile at her too. And then he saw that she was not alone. Besides her stood a short man with red frameless glasses and dressed rather casually for the colder weather with a puffy coat. Shirou was sure he had seen the man somewhere before but couldn't place where.

"Hey Sakura. Who is that?" Shirou asked curiously.

The man took a step forward "friends of yours Sakura?" he asked her.

"Yeah we are. My name is Shirou. Shirou Emiya" the young man raised his hand. But instead of a polite handshake the man looked at him with a shocked expression, as if he had seen a ghost.

"Emiya you say? Question in any way related to one Kiritsugu Emiya?" he said surprised.

And it took Shirou by surprise as well "yeah he was my father" he answered honestly.

The man's stature changed, he looked more tense and his face betrayed something almost akin to him being worried. It was an expression that he didn't lose even as he reluctantly reached out and shook Shirou's hand.

"I did not know he had a son, only a daughter…" his eyes darted to Illya who was standing besides Shirou. As soon as his eyes where upon her they immediately lit up from behind his glasses.

"Can it be? Illyasviel is that you?" the man got one knee to be on face level with the small girl.

"You're still alive. Oh it a miracle? A marvelous miracle it is. And you have not aged a day. Tell me how is it possible? I knew you were special I just knew it and…"

Shirou felt Illya clutch his hand tightly, he looked at her and saw how she seemed…almost scared. It was clear this man knew her but from where.

"Hey you're making her uncomfortable," Shirou told him while getting in between him and Illya "Sakura who is this man?"

Sakura seemed to want to answer but before she did the man gestured for her to remain still and instead got right back up.

"My apologies where are my manners I have not yet introduced myself. My name is Doctor Arefal Richter."

It then clicked in Shirou's head immediately.

"Richter….that was one of the Four Kings. The one that worked for the Einzberns…"

Shirou now fully stood in front of Illya, protecting her from him. Richter turned his gaze back on him, a seething expression on his face.

"Shirou what's going on? Who is this man and why does he know Kiritsugu's name?" Fujimura asked from behind him.

Richter seemed to scoff as he said "oh I could never forget a man like that. He was very impressive just like me. I met him as I was serving as the personal scientist of the Einzbern family. I personally tended to his wife and…." He turned his gaze to Illya "his very unique daughter."

"His what…" Shirou turned to Illya, who didn't face him and instead looked to the ground.

"Oh you didn't know," Richter taunted "are you not also Kiritsugu's son. How could you not know what little Illyasviel here is your sister! The child he left behind!"

"Liar! My father wouldn't leave anybody behind!" Shirou yelled back.

"If that was true then how come you never knew about her until this point!" Richter pointed out grinning from ear to ear.

"PLEASE STOP!" Sakura suddenly yelled. Causing everyone to turn around to her.

"Please stop. Shirou I…I was asked by my grandfather to help Doctor Richter here with his experiments that's all" she explained.

"Sakura you can't do that this man is dangerous" Shirou tried to tell.

"It's okay Shirou I promise…I'm only helping him as his assistant that's all. Doctor can we continue please."

The doctor turned to face Sakura and smiled gently "you are correct Sakura. This argument here is pointless. Let us proceed."

Sakura followed Richter as he walked past the group, setting his eyes on Illya one last time.

"I hope we meet again Illyasviel. There is still so much I wish to learn from you" he said with a sinister looking smile on his face before he and Sakura walked off, leaving the three of them behind. Shirou clenching his fist in anger, Illya looking terrified and Taiga thoroughly confused.

"Okay. You both have a lot to explain" Taiga said pointing at all of them.
