-Emiya residence-

"Shirou." Said a woman with purple hair and elf ears as she came walking into the living room with a hot pot of tea. "The tea's ready."

"Thanks Caster." smiled Shirou.

Now you're thinking, why is Caster here with Shirou? Well a while back Caster was left for dead by her previous master for no reason at all. She was about to collapse from starvation and the cold but Shirou found her and after some strange sort of Mage Ritual, courtesy of Rin, became her master along with Saber. Much to her dislike since Caster became an obsessed 'Saber-chan' otaku after seeing her cute appearance. Heck she even started making dolls with her image.

"Care to join?" he offered.

"Sorry Shirou but I have to finish something." Caster said. 'And that would be my life sized doll of Saber-chan.'

"Alright." he nodded as she left him alone. He then took a sip of his tea and sighed at the taste. 'Caster's tea is the best.' He then felt his body getting smaller for some reason. "Must have forgotten a pillow."

He stood up and left the room and walked down the hallway. As he walked he felt his clothes starting to loosen as Shirou's feet started to get smaller then his own shoes. He then started to shrink faster until nothing was left but a pile of clothes and shoes.

"Hey! What happened?!"

"Shirou?" Saber said as she walked towards the clothes. "Sigh, not again, when will Shirou learn to pick up after himself." She then grabbed the clothes as Shirou crawled on to her clothes and hid in her pockets.

"Saber! I'm down here!" he tried calling out.

"Sigh." Saber said as she placed the clothes in his room before walking out and towards her room. "Shirou, it's not a good thing to leave your stuff everywhere. It might hurt someone one day."

"Aw man, she can't hear me." he groaned.

Saber then entered her room, which was a normal room but with a picture of Shirou and Saber hugging on the nightstand, and sat on the bed. "Shirou…. am I….a good servant? Or am I a sad excuse of a person?" She thought out loud as she layed on the bed. "Heh, funny a servant like me falling for a cute young man like Shirou. I must be in a dream. If I am, don't wake me up."

Shirou was stunned before panicking as he rolled out of her pocket as she turned on her sides. "Saber….likes me?"

"Saber-chan!" Caster called out before entering her room, and ran towards her. "Hug me!"

"Gah!" Saber braced herself as Caster wrapped her up in a hug. "Caster!" Stop that!"

"Never!" She grinned before seeing Shirou. "Is that….a Shirou doll?" 'So cute!'

Saber blinked before looking down at Shirou. "What? I don't remember seeing that."

"Can I keep it?" Caster asked while looking at her with a cute face. "Please Saber-Chan?"

"Well, I don't see why not, so go ahead."

Caster smiled before letting go of Saber and grabbed Shirou. "Aw so cute!" She then walked out of the room while nuzzling the boy with her cheeks. "Just like the real thing. But naked...I think a change of clothes would work for you Shirou-kun."

"Caster! It's me! Shirou!" cried out the male in her hand.

"So cute a talking Shirou-kun doll." She smiled before walking into her room, which was covered in Saber dolls and….a life sized Shirou doll? "You know….this doll is just as cute as the real Shirou-kun."

"W-Why do you have that?!" he cried out with a blush.

Caster didn't listen as she started to put a kimono on him. "Sigh….you're as cute as Shirou-kun but not….like Jason, stupid bastard!"

"Come on Caster! I can talk and move! I'm not a doll!"

"It's amazing what advancements have been achieved in the last 2,000 years." Caster smiled. "Heck I'm amazed that I fell in love in this era."

Shirou slapped himself in the head as Caster started adding other stuff onto him.

"Yep," she smiled as now Shirou looked like a noble from Feudal Japan. "I can just imagine this on our wedding day, Shirou-Kun. With Saber-Chan as the flower girl too."

'You're kidding? Saber AND Caster both like me? Oh I can just tell this won't end well.'

"Caw!" Called out a crow that flew in and grabbed Shirou by the robes.

"GET BACK HER WITH MY SHIROU-KUN DOLL!" Yelled Caster as the crow flew off and disappeared from her sights.

"Caw caw!"

"AH! Let me go!" cried Shirou trying to pull himself out of the bird's talons.

"Caw caw!" It said before letting him go, in mid air. "Caw caw, Caw caw!"

"AHHH!" screamed Shirou waving his arms at seeing him about to hit the ground. Only to hit something soft and purple.

"Hmm?" Said a woman who looked at her bosom. "What's this? A Shirou doll?"

Shirou blinked before blushing as he landed on Rider's cleavage.

"So cute." She smiled. "I wonder if it can use magic like the real one?" Rider then poked Shirou on the stomach looking for a button.

"Hey! Rider! I'm not a doll!" he spoke scrambling back only to grab on the edge of her sweater top to keep from falling. "Help!"

Rider grabbed him and started to looked at him. "Interesting, this doll looks like and acts like Shirou…..Yep I think that whoever made this doll should be rewarded because my love is now in a cute and conveniently plushie form." She then started to rub Shirou's head with a smile.

'Why doesn't anyone listen!' he thought with anime tears while finding the rubbing relaxing.

"Maybe I should return this to Caster, I know she would love having a doll in Shirou's image." Rider said while placing Shirou into her bosom as she started to walk towards his home. "Come along Mini-Shirou, let's return you back to Caster and Saber."

He blushed even brighter feeling the soft breasts. 'Oh no, if I return to normal, they'll think I'm a pervert!'

"Mini-Shirou." Rider smiled. "Keep this a secret but I love Shirou, he talks and treats me like a normal person not like a monster that everyone knows of when they think of Medusa."

"Well of course." he spoke like it was no big deal. "Why can't you tell I'm real!"

Rider looked at Shirou. "...ok. Now I know this doll has a very sophisticated AI in it. What craftsmanship!"

'Should I even bother?'

Rider smiled as she got closer to the home before opening the door. "Saber? Caster? Are you two home?"

"Rider! I lost my Shirou-kun doll!"

"And Shirou is not in his room!" Saber called out in a panic as Shirou felt strange like his body was growing steadily. "Did you see him Rider?!"

"No, but I did find this Shirou doll."

"Mine!" Caster said before grabbing Shirou and hugging him. "Shirou-kun! Are you ok? Did that evil crow hurt you?!"

"No, I'm fine."

Caster was about to say something but gasped as Shirou started getting bigger and bigger with his clothes starting to rip with each growth until he returned to his normal height, with Caster still holding him by the hand. "S-Shirou-kun?!"

"Wooh! I'm back!" he blinked before blushing and covered his groin. "And naked!"

"Shirou!" Saber and Rider called out before blushing. "Y-You were the doll/Mini-Shirou!"

"Yes. I kept saying that, but you just thought I was sort of new doll." he frowned. "Didn't you hear the way I talked?"

"S-So you h-heard all that." Saber blushed red as Caster covered her face with embarrassment and Rider started to turn red as well and looked ready to faint.

"Yeah, but why was it so hard for you to tell it was me? There exists magic." he deadpanned.

"...it was…." Caster said before blushing. "Because I placed an ingredient in one of my potions that caused a person's perception to be distorted. If used, that person would see that person or object as something they liked….I'm sorry Shirou-kun!"

"I apologize as well." Saber bowed her head.

"Same." Rider said while looking to her side. "I should have looked more carefully, Shirou."

Said male sighed. "It's alright, but lets try to keep potions like that out of the house."

"Yes, Shirou-kun." Caster said before blushing. "But you heard us confess right?"

He blushed and nodded.

"...then," all three said before looking at Shirou with blushes. "W-What do you think?"

"W-What do you mean?" he asked.

"Do you," Saber blushed.

"Like," Caster spoke while looking away from Shirou's family jewels.

"Us like lovers?" Rider said while feeling faint.

Shirou gulped and saw each one nervous. "Um….well….right now it might seem a little….awkward, but if you three are fine with sharing, I don't mind."

All three thought for a few seconds before hugging Shirou. "Yes Shirou/kun!"

He blushed while coughing. "Um, I still need to get dressed."

They jumped back before blushing with Rider fainting onto the ground muttering 'Shirou's...jewels…'

-Timeskip one month-

"Shirou?" Rin called out as she opened the main door. "Are you home?"

"In here!" He called from the main room.

Rin nodded as she walked into the main room. Only to see Shirou, Saber, Caster and Rider on the couch watching the Titanic. "Um...what's going on?"

"We're watching a movie." replied Rider with a straight tone.

"A romance movie?" Rin said while unconvinced. "That's not normal, you four usually watch sci fi movies, like Alien or Planet of the Apes."

"We wanted something more romantic." smiled Caster with her head on Shirou's lap.

"And something with tragedy." Saber said while laying on Shirou's arm. "I-It's so sad!" She sniffled as she saw the ship sinking into the Atlantic.

"Sometimes a little tragedy makes it all the more beautiful." spoke Rider on Shirou's chest.

"So don't cry Saber-chan." Caster said trying to comfort her. "It's ok, we have Shirou-kun here, he won't leave us or let such a thing happen to us."

"Shirou-kun?" Rin asked confused at the suffix. That was before the three girls kissed Shirou's cheeks and, in Casters' case, his lips. "W-WHAT!?"

"What? We're kissing oru boyfriend." spoke Saber.

Rin looked at them in shock before fainting.

"...ok…..So what should I tell Sakura?" Rider asked knowing of her 'protectiveness' of her crush/sempai.

"Just tell her the truth and be gentle about it."

"Or we could shrink her?" Caster suggested.

"No!" Shirou, Saber and Rider yelled.

"Aw!"
