Author's note: For those who are wondering when's Morgan's chapter is coming, that will happen soon, so be patient.

Also, the song Mysterious Idol X Alter was singing is "This Illusion" by LiSA.

Ritsuka was walking down the hallway, pumped for his usual summoning sessions. "All right, let's see what I'll summon today..." he thought as he was happily carrying his saint quartz. Soon, he arrived at the summoning room and he placed the saint quartz onto the summoning alter. "Come on summoning system, give me something good..."

Soon, Ritsuka then placed the saint quartz onto the summoning alter. As he did, the alter lit up and in an instant, multiple blue orbs appeared in the air and connected with each other. They then turned into a right of blue sparks and swirled around with each other, forming a ring that then split into three and continued to swirl around until it turned into a pillar of light.

As the light faded, it revealed a gold card showing a hooded person with glowing eyes. Soon, the card disappeared, and in its place was a person who looked like Mysterious Heroine X Alter but was wearing different clothes. Not only that, but there were also objects that look like speakers floating around her and she was carrying a guitar.

"Class, Foreig-...Saber. Or rather, I'm an idol, so...currently for sale for the entire universe, with the altereactor fully open and the idolium at full throttle. I won't mind if you feel like calling me Ecchan."

For a moment, Ritsuka didn't say anything as he was trying to process the information and the person in front of him.

"Ecchan...she looks like Mysterious Heroine X Alter, but with major changes. I wonder if she is related to her..."

"Is there something wrong master?" Ecchan asked, snapping Ritsuka out of his thoughts.

"Hm? Ah, no. It's just that...well, you look a lot like someone..." Ritsuka replied.

Ecchan was silent for a moment before continuing the conversation. "You mean there are other people here with the same face as me?"

"Well...yeah."

"Are they all idols?"

Ritsuka shook his head. "No. All of the people with the same faces as you are not idols. Although we have servants who are trying to be idols."

"I see...no matter, I will show those other idols who the number one idol is," she said as she played some of the strings on her guitar.

Ritsuka chucked at Ecchan's behavior. "I-I see...anyways, welcome to Chaldea Ecchan."

"Chaldea? Is that where we are right now? It sounds like the perfect place for a stage."

"Yeah. And sadly, there isn't a stage here," Ritsuka replied. "Although Da Vinci would be able to create one within in instant..."

"Master," a new voice said, which Mysterious Idol X Alter immediately recognized.

"That voice...it can't be!" she thought in shock.

Both Ritsuka and Mysterious Idol X Alter heard the voice and turned around to see Mysterious Heroine X Alter, who was standing at the entrance of the summoning room. At that moment, both Mysterious Heroine X Alter and Mysterious Idol X Alter were shocked seeing each other in the flesh.

And they had one thought in mind.

"T-That's me?!"

For a moment, both Mysterious Heroine X Alter and her counterpart looked at each other with shocked eyes while pointing at each other. "Who are you?" Mysterious Idol X Alter asked.

"Me? My name is Mysterious Heroine X Alter. Who are you, imposter?" she asked as she drew out her sword.

"Me? My name is...Mysterious Idol X Alter," Mysterious Idol X Alter replied back.

Mysterious Heroine X Alter can't help but felt a twitch in her body. "You just made that one up, didn't you?"

"No, I did not," Ecchan denied. "Anyways, I can't believe I'm saying this...but you're me."

"What?! That's impossible. And if what you're saying is true, let me ask you these few questions that you should know since you claim that you're me. First, what kind of food is the worst in the entire universe?"

"Potatoes made by Gawain the Mash. They have no flavor whatsoever," Mysterious Idol X Alter replied immediately.

"Hm...she answered that question quite easily. And furthermore, she said the same answer I would," she thought. "Next question, which brand of dorayaki is the best dorayaki in the entire universe?"

"Dorayaki made by Cutest Good Wife Cos-Tamamo is the best dorayaki in the entire universe."

Mysterious Heroine X Alter was amazed with her answer, because her answer was the same as her. "Okay, due to these answers, I'm starting to think she's me. However, this final question should prove it to see if she's me or not. After all, only I know this question..." she thought. "Okay, final question. Which website do you use to buy your stuff?"

" , which is a reality-spanning shopping website renowned for its excellent services."

At that moment, Mysterious Heroine X Alter immediately knew who the person was in front of her and relaxed her weapon. "Okay, you're not an imposter of me...rather, you're me."

Ritsuka was shocked upon hearing her sentence. "Eh?! Mysterious Heroine X Alter, That's you?!"

"Well, seems so. Since she answered those questions the same way I would, it proves that she's me. Although I can't believe it, even in front of my eyes as well," she said as she headed up towards Ecchan. "Anyways, sorry about attacking you earlier," she said as she raised her hand.

"It's fine," Mysterious Idol X Alter replied as she shook Mysterious Heroine's X Alter hand. "So yeah, I'm you...from a future point in time."

"Really?"

"Yeah."

For a moment, nothing happened between the two as they were examining themselves. Then Mysterious Heroine X Alter asked Ritsuka a question. "Hey master, do you mind if I take her on a tour in Chaldea?"

"Eh? Are you sure?"

"Yeah."

"I see. How about you Ecchan?"

"I don't mind, considering it's myself that's giving the tour after all," Mysterious Idol X Alter replied.

"Well, as you wish, you can take Ecchan on a tour of Chaldea."

Mysterious Heroine X Alter let out a smile. "Great, let's go then."

And the two left the room, leaving Ritsuka alone. "Well...it appears I've summoned a slightly older version of Mysterious Heroine X Alter...I hope things go well, especially if she meets Mysterious Heroine X and XX..."

"Eh? Is that so?" Mysterious Idol X Alter asked while eating some candy.

"Yeah. So, if you want to get some sweets here, there's a mini mall in Chaldea filled with sweets shops of many kinds," Mysterious Heroine X Alter replied as she took a bite out of her sweets.

"I see. And what's that room over there?"

"Hm? Ah, over there is one of Chaldea's relaxation rooms. Over there, servants can take a break on any of the sofas over there whenever they feel like it."

"I see...that sounds like a good place for me to sing."

"Eh? You can sing?"

"Yeah. Do you want to hear it?"

Mysterious Heroine X Alter nodded in reply.

"Very well."

Mysterious Idol X Alter then began to head towards the recreational room, where luckily, no was in there aside from her and Mysterious Heroine X Alter. She then sat down on a sofa while Mysterious Heroine X Alter did the same as well. As she did, she then tweaked her guitar while adjusting her speakers.

Soon, she began to sing.

"A cry that couldn't reach the shadow of that day I was dreaming about.
No matter what I draw tomorrow.
Get wet with an indelible wish.
Grab the spilling pieces with your hands.
Hold your swaying heart and jump into the night.
Even if you rely on someone.
Because it's not what you want.
I'm here.
Don't close your eyes.
A nostalgic smile that was sown by the wind.
No matter how much I pray for tomorrow.
The answer that goes away is hazy.
Freezing body and a piece of thought.
Before it decays, jump over the night.
Even if you rely on someone.
Because it's not what you want.
I'm here.
Don't close your eyes.
Live for someone.
This moment is all right.
Gently throw away the fake self.
Just as it is."

As she was done singing the song, Mysterious Heroine X Alter let out a few claps and a small smile at the same time. "Wow. I'll admit, that was amazing. I never knew I was capable of something like this."

Mysterious Idol X Alter let out a smirk. "Why thank you."

It was then at that moment that an unexpected person came into the room.

Elizabeth Báthory, Chaldea's acclaimed idol.

"Hm? What are you doing here?" Mysterious Heroine X Alter asked.

"Well, I was walking down the hallway earlier, and I overheard her singing. I'll admit, your singing is not bad...but it won't beat my singing!" Elizabeth said.

"Hm? Who are you?" Mysterious Idol X Alter asked.

"Me? Well, my name is Elizabeth Báthory! Chaldea's number one idol and the best idol for master!"

At that moment, Mysterious Idol X Alter was interested at Elizabeth's words. "Chaldea's number one idol? The best idol for master? You?"

"Yeah! And who are you by the way?" Elizabeth asked.

"Me? Well...my name is Mysterious Idol X Alter...nice to meet you," Ecchan replied.

"I see! A fellow idol! Well then, as a gift from your senpai ido, I will sing to you!" she exclaimed as she brought out a microphone. "All right then, hear my singing!"

However, it was then that Mysterious Heroine X Alter grabbed Ecchan and began running for her life, dragging her along with her.

"What the-?!" both Ecchan and Elizabeth said in unison.

"Don't. It's not worth it hearing her singing," Mysterious Heroine X Alter said as she bolted out of the room along with Mysterious Idol X Alter, leaving behind an angry Elizabeth.

"Hey! Get back here!" she yelled in the distance.

After many minutes of running, both Mysterious Heroine X Alter and Mysterious Idol X Alter were finally at a safe distance from Elizabeth. "Hey, why were we running? I was in a challenge against another idol," Ecchan asked.

Mysterious Heroine X Alter let out a sigh. "Listen, by any means, never listen to her singing. It's really bad."

That got Mysterious Idol X Alter interested in a bit. "Really? How bad is it?"

"...So bad that if one hears her singing, that person goes deaf for a short amount of time. It's quite demonic actually."

Mysterious Idol X Alter was shocked. "Really? It's that bad."

"Yeah. In fact, the last time she sang, nearly a bunch of people were in the medical center for a while."

"Wow...that's something new. Talk about lethal singing..."

At the two were chatting, it was then that two certain servants happened to pass by.

Which were Mysterious Heroine X and Mysterious Heroine XX.

Upon seeing Mysterious Idol X Alter, Mysterious Heroine X let out a scream. "Ah! A new saber-face! And you look like Ecchan! You must be destroyed!" she yelled as she brought out her sword.

"Geh! You're here too?!" Mysterious Idol X Alter yelled as she emitted a beam out of her guitar.

"Hm! This presence...you're a foreigner!" Mysterious Heroine XX said as she brought out her weapon.

"Eh?! Who are you?! And why do you look like her?!"

"Me? I'm Mysterious Heroine XX!"

"Hm?! Does that mean you two are related to each other! Not that it matters, you two will be destroyed here, right now!" she yelled as she swung her guitar at both Mysterious Heroine X and XX.

"Tch!" they said as they prepared to defend themselves. However, before they can do, it was then they smelled something that made them drop their weapons. At the same time, Mysterious Heroine X Alter stopped her counterpart.

"Hey, why are you stopping me?" Mysterious Idol X Alter asked.

"Hold one for one moment," Mysterious Heroine X Alter replied.

For an instant, Mysterious Idol X Alter was puzzled by what her counterpart said...until she got her answer from her other counterparts.

"This smell...it's Shirou's food!" Mysterious Heroine X exclaimed in joy before she immediately ran towards the source of the smell.

"Hey! Wait for me! I want some of Shirou's food now!" Mysterious Heroine XX exclaimed as she followed her.

Meanwhile, Mysterious Idol X Alter was confused with the events that just happened. "Um...what just happened? And what is this amazing smell I'm smelling right now?" she asked.

Mysterious Heroine X Alter let out a smile. "Well...let me show you, because what's about to happen next will blow your mind." She then grabbed her counterpart's arm and began to take her to the cafeteria. As they arrived at the cafeteria, they saw Shirou, who was behind the counter making food for both X and XX.

"Is that the source of this amazing smell?" Mysterious Idol X Alter asked.

"Yeah. And the person at the counter is Shirou. Be nice to him. He can make good food," Mysterious Idol X Alter replied.

Soon, both went into the cafeteria. As they did, Shirou noticed Mysterious Idol X Alter along with her counterpart. "Hm? Oh, hey there Arturia. Is that your counterpart over there?" he asked.

"Yeah. She's my older self from another timeline. Call her Mysterious Idol X Alter, or Ecchan in this case. Ecchan, this person is Shirou," Mysterious Idol X Alter replied.

"I see. Nice to meet you Ecchan," Shirou said with a smile on his face.

"Yeah. Nice to meet you too Shirou," Mysterious Idol X Alter replied as she heard her stomach growl. "Uh oh...looks like I'm running low on energy now..."

Shirou let out a small chuckle. "Do you want me to make something?"

"Yes please..."

Soon, Shirou began to make a burger meal for Mysterious Idol X Alter to eat. As he was done with the dish and presented it to her, Mysterious Idol X Alter was in awe. "Wow. This burger looks good...let's see how it tastes..." She then took a bite out of it, and when she did, she tasted heaven on earth. "Wow...so delicious..."

As Mysterious Idol X Alter ate the burger in complete bliss, her counterpart looked at her with a smile on her face. "Well, is it good?" Mysterious Heroine X Alter asked. Mysterious Idol X Alter nodded with agreement. "Good. I'm glad that you like it. Speaking of which, Shirou, I also want a burger as well," she said as she turned to Shirou.

"As you wish."

Soon, Shirou made a burger set for Mysterious Heroine X Alter, and like her counterpart, she ate it with glee. Soon, both were done with their burgers while X and XX were still eating.

"Well, that was pleasant. I've never had a burger this good..." Mysterious Idol X Alter said with content.

"Yeah. Not only that, but Shirou's also good in many things, ranging from cleaning to organizing to many other things..." Mysterious Heroine X Alter replied.

"Is that so...?"

"Yeah."

For a moment, nobody didn't say anything...until Mysterious Idol X Alter said a question.

"Hey, can I have Shirou as my personal manager?"

In an instant, all three heroines dropped what they were doing and yelled, "NO!"

Omake

Mysterious Idol X Alter was walking down the hallway, minding her own business as she was heading towards the cafeteria to get her daily intake of sugar and energy. As she arrived, she witnessed something that nearly made her drop her mouth.

Which was Arturia and her counterparts, and they were eating.

Mysterious Idol X Alter couldn't believe the sight in front of her. "Wow, and I thought seeing X and XX was crazy, but this...this is just too complicated for me...and some of those saber-faces...have different shapes..."

As she looked her Lancer, Lancer Alter, and Ruler counterparts, she took a look at herself.

And she felt jealous.

"All right, I'm going to drink more milk later..."
