"Bzz! Bzz!"

Shirou moaned as he heard his alarm clock from the nearby stand right next to his bed. He then raised his hand to proceed to turn it off. "Mnnnh...it's already morning?" Shirou thought to himself as he got out of bed. As he did, he then went into the bathroom to refresh himself for the morning.

However, when he was about to do so, he then looked in the mirror, and noticed something.

His face and hair looked different. His facial features looked more feminine and his hair was longer, reaching to the half of his back. Not only that, but his hands were small, the calluses gained from continuous practice, gone.

And that wasn't the end. When he looked down at himself, he noticed that his body has changed as well.

In which case, he now has the body of a female supermodel in which he has breasts that were noticeable along with the butt as well.

At that point, Shirou had one thought to himself.

"WHAT IN THE ROOT IS THIS?!"

Shirou sighed as he was walking in one of Chaldea's hallway with nearly everyone gazing at him. Right now, in order to adjust to his current situation, he was wearing the white kimono he was using as a cape of sort fully as his normal outfit shows his body off. "Jeez. Just how did I wake up to this? I mean, I haven't even done anything that would have an effect like this on me! Who or what did this to me?! I swear, I'm going to ask Da Vinci later to see if this is the result of one of her experiments..."

As Shirou was walking, he eventually stopped by the cafeteria...which included Arturia and her counterparts, Ishtar and her counterparts, Parvati, Kama, BB and her sisters, Illya and her counterparts, Miyu, Astraea, Irisviel, Kiritsugu, Jaguar-man, EMIYA, and EMIYA Alter.

And they were shocked when they saw Shirou in this state.

"SHIROU?!"

"EMIYA-KUN?!"

"SENPAI?!"

"ONII-CHAN?!"

"SHEROU?!"

"SHIROU?!"

"Shirou?!"

"WHAT THE HELL?!"

Shirou sighed as he heard the reactions from everyone that were in the cafeteria. "Well, guess I'm going to explain how I ended up like this now..." he thought as he entered the cafeteria. For a short while, there was silence in the air as everyone was in awe and were trying to process the sight in front of them.

Then one person decided to speak out.

"Um...Shirou...can you explain what has happened to you?" Kiritsugu asked.

"Well honestly...I don't know," Shirou replied as he sat down on a chair.

"But how though?! How did something like this happen to you?!" Jaguar-man asked dramatically.

"I don't know. All I remember is that I was normal last night, went to bed as usual, and suddenly, I wake up this morning as a girl! Honestly, I did not expect anything like this to happen!"

"I see. What did you do yesterday? There could be some clues in there over what could happen," Irisviel said.

"Hmm...I was practicing my swordsmanship in the training room. As I did, it was then that I took a break and went by to the rest area and grabbed my water bottle."

"I see. Was there anything suspicious about your water bottle?"

"Not quite actually. It tasted normal."

"Anything else?"

Shirou gave Irisviel's question a long thought. It was then that she realized something. "Now that you mentioned it, I did get a glimpse of Merlin nearby."

That immediately got Arturia and her counterparts riled up. "Merlin did you say?"

"Yeah. I did see Merlin nearby the area. However, when he saw me, he quickly left. Why?"

For a moment, there was an air of silence as Arturia and her counterparts were wondering why Merlin happened to be where Shirou was. As they were thinking about this issue, they realized something.

Merlin was behind this.

"MERLIN!" they all thought in unison.

"Um...Arturia?" Shirou asked.

However, it was then that Arturia and her counterparts immediately left the room, immediately surprising everyone.

"Arturia?!"

"Shirou! Me and my counterparts will be back soon! We just have to find Merlin for something!" Arturia said as she and her counterparts quickly left the cafeteria.

Shirou was dumbfounded for a moment. "What was that about?"

"Um Senpai, are you okay?" Parvati asked, snapping Shirou out of her thoughts.

"Y-Yeah. I'm just confused with what's going on here," Shirou replied.

"You're telling me. How is it that you were turned into a girl? And in a night never less?" Kama asked.

"Yeah. Although you do look cute like that," BB said with a smug grin on her face.

"A female senpai...that's new," Passionlip said.

"Yeah. Especially when he, or rather she, looks completely different than what I'm used to..." Meltlilith said.

"Wow...a female Senpai..." Kingprotea said in awe.

As Parvati, Kama, BB and her sisters were looking in awe, Ishtar had a different reaction upon seeing Shirou as a girl. Shirou turned to see Ishtar and her rider counterpart looking at her in jealously.

"Um...Ishtar, are you alright?"

For a moment, she didn't say anything as she along with her rider counterpart continued looking at Shirou. Then she began to mutter something.

"It's not fair..." she muttered.

"Um...Ishtar, are you okay?" Shirou asked, unaware of the danger she was about to put herself in.

Ishtar then grabbed Shirou's shoulders and started to shake her quickly. "It's not fair! How is it that despite me becoming a goddess, my body hasn't changed?! You on the other hand, had yourself turned into a girl overnight by unknown means, and somehow gain a body of a supermodel! Especially one with a giant chest! It's not fair!" Ishtar ranted as she kept shaking Shirou over and over.

"Yeah! This is completely unfair! I want to have a chest like that too!" Rider Ishtar yelled as she joined her counterpart.

"I-Ishtar! Calm down!" Ereshkigal yelled nervously.

"Not now Ereshkigal! Not until I give Emiya-kun a piece of my mind!" Ishtar and her rider counterpart said in unison.

However, as Ishtar and her rider counterpart continued shaking Shirou, Astraea came in and stopped Ishtar and her rider counterpart from shaking Shirou even further.

"Stop it! Leave Sherou alone you useless flat-chested goddesses! Both of you are just jealous that Sherou's more beautiful than you now that he's a girl!" Astraea yelled.

"What was that Astraea!?" Ishtar yelled, turning her attention to Astraea.

"Hmph! Like I said-," Astraea said, but was cut off from Ishtar shooting a gem into her face. "Why you!" Astraea then began a fight with Ishtar and her counterpart as she shot a gem at Ishtar, but she dodged it, hitting Rider Ishtar.

"Hey! You bitch!" Rider Ishtar yelled as she launched herself at Astraea.

Soon, a war fight between Ishtar, her rider counterpart, and Astraea began as all three of them started to fight against each other. As they were fighting, Ereshkigal was helping Shirou get up from the ground.

"Are you okay Emiya-kun?" Ereshkigal asked as she picked Shirou up from the ground.

"Y-Yeah. I think I'm fine. Thanks, Ereshkigal," Shirou replied.

"N-No problem..."

Meanwhile, Illya and her counterparts were talking among each other about Shirou's sudden gender change.

"So that's what onii-chan looks like as a girl..." Illya said.

"Yeah. I'll admit, he is beautiful..." Kuro said.

"I agree. Who's the one that turned him into like this?" Sitonai said.

"I don't know. Anyways, want to meet him?" Miyu asked.

"Yes!" Illya, Kuro, and Sitonai replied.

As Shirou got back up, Illya and her counterparts along with Miyu came up to her. "Um...onii-chan? No wait, um...should we call you onee-chan in this case?" Illya asked.

Shirou sighed. This was going to be complicated. "Well, in this case, I guess you would call me by that."

Kuro smirked. "Then...onee-chan!" she said as she suddenly gave Shirou a hug.

"Ah! Kuro! That's not fair! I want to hug onee-chan!" Sitonai said.

"Me too!" Miyu said.

"So do I!" Illya said.

"Hey! You snooze, you lose!" Kuro replied with a smug grin on her face.

Not wanting to be left out, Illya, Sitonai, and Miyu then all gave Shriou a giant hug. Meanwhile, Irisviel, Jaguar-man, and Kiritsugu were looking at Shirou's current condition, and were still stunned.

"Wow...you don't see this every day..." Kiritsugu said.

"I know right! My son is now a girl! I now have a cute and sexy daughter!" Iriviel exclaimed happily.

"This is weird, seeing Shirou like that..." Jaguar-man said.

As Illya and her counterparts along with Miyu continued hugging Shirou, he felt uncomfortable and felt the need for them to let go. "Um...Illya, Kuro, Sitonai, Miyu? Can all of you let go now? I need to head to the kitchen now," he asked.

"Yes!" they all said in unison as they let go of him.

Shirou sighed as she was released from her little sisters' hug. As they released her, Shirou then went to the kitchen, where EMIYA and EMIYA Alter were still stunned upon seeing Shirou.

However, before he could do so, Irisviel caught him in a hug.

"Wha-mom?!" Shirou said.

"Wah! Shirou, you look so amazing as a woman! You're so cute and sexy!" Irisviel replied happily.

"M-Mom! Let me go!"

"Never!" Irisviel said as she hugged him tighter.

Seeing how uncomfortable Shirou was, Kiritsugu went over to where Irisviel was and placed a hand on her shoulder. "Let go of Shirou now Iri. He's now uncomfortable from your hugging. And plus, he needs to get back to work. Okay?"

Irisviel pouted. "Fine..." she said as she let go of Shirou.

Shirou sighed. "Thanks, old man..."

"No problem," Kiritsugu replied as he dragged Irisviel away.

Soon, Shirou arrived at the kitchen where EMIYA and EMIYA Alter were waiting for him. They were still looking at him in shock.

"Well, you're going to get used to seeing me like this for a while..." Shirou said.

EMIYA and EMIYA Alter sighed. "Just how do you keep getting yourself in these situations?" EMIYA asked.

"Yeah. It's quite ridiculous how you managed to get your gender changed like that overnight," EMIYA Alter said.

"I have no clue. Honestly, I thought both of you would know since both of you are me after all," Shirou replied.

EMIYA and EMIYA Alter nearly flinched at what Shirou just said.

Shirou sighed as he was trying to get used to the newfound attention he was receiving now. Earlier, when he was walking in the hallway, he received a lot of attention from the servants he would pass by.

Especially when some of them were servants that knew Shirou.

In Cu and his counterparts' case, they were amazed with how Shirou looked as a woman.

In Medusa and her counterparts' case, they were surprised with how Shirou looked as a woman, especially Medusa.

In Caster Medea's case, she somehow managed to get clothes appear out of nowhere and wanted to dress Shirou up, creeping him out immediately.

In Berserker Hercules's, he just roared.

In Sasaki Kojirou's case, he was complemented over his beauty.

In Gilgamesh and his counterparts' case...well...it didn't end so well...in which Archer Gilgamesh flirted with Shirou and trying to force himself on him without knowing who he was. And that ended in Shirou kicking Archer Gilgamesh right in the balls while the Caster and Kid counterparts looked at the event in disappointment.

In Nero and her counterparts' case, they commended him for his beauty despite turning into a woman.

In Jeanne D'Arc and her counterparts' case, Jeanne D'Arc and her alter santa lily counterpart were surprised while Jeanne D'Arc Alter just laughed at his misfortune.

In Okita and her counterpart's case, they were amazed with how Shirou turned into a woman.

In Musashi's case, she was rather excited.

In Jack, Paul, Nursery, and Abigail's case, they were in awe over Shirou as a woman. Especially Jack since she didn't stop calling her mother. And she had somewhat of a legit reason.

In Arthur's case, he was surprised.

In Amakusa Shirou's case, he was surprised like Arthur.

In Hakuno's case, she was surprised.

In Scathach and her counterpart's case, they didn't care.

In Waver's case, he was shocked.

In Ritsuka and Mashu's cases, they were shocked.

In Da Vinci's case, she was excited as she wanted to know what/who did this.

Shirou sighed at the many interactions he had to go through during his time as a woman. "When will this end? This day has got weird ever since I've been turned into a girl by unknown means. Speaking of which, where is Arturia and her counterparts? I haven't seen them ever since I told them that Merlin was nearby. Where are they?"

As if on cue, Merlin then appeared in front of Shirou, running for his life as he was running from Arturia, her counterparts, and the Knights of the Round.

And he looked like he was scared.

"Queen Shirou! Please save me!" Merlin yelled in fear as he hid behind Shirou like a little kid.

"What the-Merlin?!" Shirou said as he was confused with the situation that was happening around him.

At that moment, Arturia, her counterparts, and the Knights of the Round finally caught up to Shirou and Merlin.

"Shirou/my queen/mother, please move out of the way," they all said in unison.

"Uh, why?" Shirou asked.

"Because it's Merlin's fault that you're in this condition!"

Shirou was shocked. "What?!"

"Yeah! Ask him! He's the one that made you like this!"

Shirou then turned to Merlin. "Merlin, what is the meaning of this?" he asked with an angry tone.

"Heh heh heh...well..." Merlin said.

"Answer me."

Merlin sighed as he now knew that there was no way getting out of this situation. "Okay, yes. I am the reason why Queen Shirou has been turned into a woman," Merlin admitted.

"How?"

"Well yesterday, I may have...swapped Shirou's water bottle with one that had a potion that turns people's gender into the opposite..."

"And why did you do it?" Arturia, her counterparts, and the Knights of the Round asked.

"Well...because I was bored?" Merlin asked with a nervous smile on his face.

At that moment, there was silence in the room as everyone was quiet after hearing Merlin's answer. For a moment, Merlin thought he was safe from any punishment.

However, Arturia and her counterparts had something else to say.

"Should we unleash him?" Arturia asked.

"Yes," her counterparts said.

"I agree," the Knights of the Round said in unison.

"Great. Bedivere?"

Bedivere nodded and soon left the hallway. For a moment, Shirou and Merlin were confused with why Bedivere suddenly left the hallway. After a few minutes, he came back.

With Fou in tow.

"Uh oh," Merlin said, knowing what was going to happen next.

In an instant, Fou launched himself from Bedivere and immediately kicked Merlin in the face. "Die Merlin, Foooouuu!" Merlin was launched back by the force of Fou's kick and landed into the ground. Soon, Fou began to tackle Merlin, and the two engaged in a fight.

As Fou and Merlin were fighting amongst each other, Arturia, her counterparts, and the Knights of the Round began talking to Shirou.

"Are you okay Shirou?" Arturia asked.

"Y-Yeah. I think I'm going to be fine. What about Merlin though?" Shirou replied.

"Eh. He'll live," Arturia Alter said.

"Yeah. This is payback," Arturia Lily said.

"Not only for you, but the number of pranks he pulled on all of us," Lancer Arturia said.

"And plus, he's already beaten by Fou so many times. Something like this wouldn't kill him," Lancer Arturia Alter said.

"That's right," Ruler Arturia said.

"Is that so? How long will it take until Fou stopped beating up Merlin?" Shirou asked.

"Honestly, I have no clue," Archer Arturia said.

"Yeah. Every time when Fou and Merlin meet, it always ends with Fou kicking Merlin in the face," Rider Arturia Alter said.

"Yeah. And we don't even know how long until the beating takes," Santa Arturia Alter said.

"Not only that, but we also don't know where the beating takes place," Mysterious Heroine X said.

"So, either way, we just let Fou kick his ass," Mysterious Heroine X Alter said.

"Exactly," Mysterious Heroine XX said.

"I see...and all of you are okay with Fou beating up Merlin?" Shirou asked.

"Yes. It shames me to say this, but it feels refreshing to see Merlin getting beat up like that," Gawain said.

"Exactly. The many times he pulled pranks on all of us...it just haunts all of us to no end," Lancelot said.

"And the aftermath of the all...was just too painful..." Tristan muttered.

"Even I couldn't bear with some of Merlin's pranks..." Bedivere said.

"As do I..." Gareth said.

"So mother, if you're worried about Merlin, don't worry. He's used to dealing with this every day," Mordred said.

"I see..." Shirou said as he returned looking at Fou still beating up Merlin.

"Ow! Get off me Cath Palug!" Merlin yelled.

"Fou!" Fou replied.

As Merlin and Fou continued fighting among each other, Arturia then called out Merlin. "Hey teacher, would you mind giving the cure to Shirou now? If you do, I'll tell Fou to stop."

"Tch...fine! Just get Cath Palug off me!" Merlin groaned as he was punched by Fou in the face.

"Good. Shirou? Would you call Fou here?"

"Uh...okay. Fou, come over here," Shirou said.

Upon hearing Shirou's voice, Fou stopped beating Merlin and headed towards where Shirou was. Shirou kneeled so Fou can grab onto him. As he did, Fou easily climbed up to Shirou's shoulder. Merlin then got up from the beating and pulled out something from his pocket.

"Here Queen Shirou. Here's the antidote to the situation you are in now," Merlin said as he showed Shirou a small red vital. Shirou then grabbed the vital from Merlin's hand and then drank it. As he did, he felt a change going through his body as he felt that his body was turning back to normal.

At that moment, Shirou returned to normal. "Phew. Well, guess everything is back to normal now."

"Yeah. Well...except for Merlin here," Mordred said as she, Shirou, Fou, the rest of the Knights of the Round, Arturia, and her counterparts looked at the poor state Merlin was in from the beating Merlin was in.

"You can say that again..." Shirou said.

"I know right? By the way mother."

"Hm? What is it Mordred?"

"To be honest, when we all heard that you were turned into a woman by Merlin, a part me of wished that you would stay like that for a while."

Shirou was confused. "Why?"

"So that way I won't get any stares when I call you mother," Mordred jokingly said.

Shirou sighed. "Really?"

"Yeah. Also, it's also glad that we found Merlin first, or else Lancelot would have gone after you by mistake."

Lancelot felt insulted by what Mordred just said to him. "Hey!"

Omake

EMIYA was waking up in his room, minding his own business. As he did, he noticed something.

His arms were smaller.

"What the heck? Why did my arms turn smaller? Wait. Does that mean...?!"

In an instant, EMIYA went into the bathroom to check on himself. As he did, he was in shock upon seeing himself in the mirror

He was a woman now.

"WHAT THE HELL?! HOW DID I GET INTO THE SAME SITUATION AS MY YOUNGER COUNTERPART?! THIS IS EVEN WORSE THAN THAT DEAL I MADE WITH ALAYA! WAIT, DOES THAT MEAN-?!"

(Meanwhile...)

"You've got to be kidding me! What the hell is this?! This is even worse than that deal I made with Kiara!" Emiya Alter thought as he looked at the mirror where he, like EMIYA, was turned into a woman.
