“Oh my, what a rare guest, Sawamura-kun.” Kasumigaoka Utaha crossed her legs and looked at Eriri with anticipation. “It’s surprising that the princess of Dai-i would deign to come to the school.”

You see, they hadn't been to school for a long time, and it was quite an unexpected coincidence that they bumped into each other on their first day back. As for running into each other in clubs, that wasn't surprising, since they were from different grades and didn't have much interaction outside of these clubs.

"You are the one, Kasumigaoka," Eriri said with a forced smile. "Didn't Emperor Charlemagne's Master also come?"

"Me? After all, leaving the club requires showing sincerity in person. I'm not a busy person like a princess." Kasumigaoka Utaha explained lazily. After completing the game script, she had finished her task and didn't have much time to play house with Aki Tomoya.

Honestly, if I hadn't had some feelings for Aki Tomoya back then, how could Kasumigaoka Utaha, an already famous light novel author, have come to be a game scriptwriter? Not to mention that Aki Tomoya's plan was just two dry sentences, and his own circle was completely unknown.

On the other hand, Eriri is in the same situation, only helping out because she and Aki Tomoya are childhood friends.

Now that both of them have lost interest in Aki Tomoya, they naturally don't want to waste any more time in the club.

Eriri glanced at her: "Me too."

They actually had the same idea as this guy! x2 The two of them had the same thought at the same time, and they both felt very uncomfortable.

That annoying Kasumigaoka Utaha, what kind of scheme is she up to now? Could Charlemagne have been fooled by her? —From Eriri

Foolish Sawamura, once again indulging in her excessive arrogance and inappropriate behavior without thinking. I really don't know how King Arthur tolerated her. —From Kasumigaoka Utaha

Honestly, although a lot has happened during this time and the two of them have changed a lot, their animosity remains unchanged!

The two fell into silence again.

"Honestly, I can't correct your overly arrogant nature, your dishonest behavior, and your tendency to create trouble for yourself. King Arthur will soon get tired of you."

Kasumigaoka Utaha commented casually as she flipped through the book.

Eriri was so angry her hair was practically standing on end: "Arthur would never do that!"

Eriri retorted in a fit of pique: "You're the one who's scheming and gloomy! Be careful, or Charlemagne might see through your true colors and hate you because he can't accept it."

Kasumigaoka Utaha tightened her grip on the book's pages, crumpling one corner.

She slowly put down her book, a polite smile on her face: "There's no need for you to worry about that, Sawamura-kun. This is between Charlemagne and me."

Lightning flashed and thunder roared as their eyes met.

So why do these two people have to be so roundabout in their expressions of concern for each other, which can lead to misunderstandings?

"This is infuriating—"

Then, the classroom door was suddenly opened, and a familiar voice, which no one could immediately recall where they had heard before, entered the ears of the two people who were facing off.

The two almost instantly suppressed their confrontational expressions. Kasumigaoka Utaha opened her book again, while Eriri snorted and opened her sketchbook to continue drawing.

After all, they were both Masters, so it was fine for them to bicker in private, but they couldn't argue publicly. Doing so would lead others to mistakenly believe that there was a conflict between King Arthur and Charlemagne, and given their historical significance, it would stir up unnecessary disputes.

The two girls were no longer the naive young girls they once were, and naturally knew what was important.

But when the two of them turned their gaze to the person who came in, they both froze in shock.

The newcomer stared blankly at the two of them, the sketchbook in his hand falling to the ground.

"What's going on?!"

That voice, that tone, and that appearance—it's undoubtedly the utterly arrogant Eriri Sawamura Spencer.

The blonde girl standing at the door stared in disbelief at Eriri, who was sitting in her seat. Suddenly, she jumped up, pointed at Eriri, and said, "You, you, who are you? Are you a doppelganger? Or some kind of monster!" Her thinking was just as unpredictable.

"You're the monster!" Eriri roared, slamming her hand on the table. "Who do you think you are?!"

"What are you doing making such a racket and blocking the way here, Sawamura-kun?" A lazy and indifferent voice came from outside.

Then, the door, which the blonde girl had only partially opened, was fully pulled open, and a girl with black hair and a white headband walked in, saying, "Have you finally gone mad?"

Eriri would normally be furious.

Then, she met a pair of unusually familiar red eyes, and an even more familiar face—a face she saw in the mirror every morning.

The two Kasumigaoka Utaha looked at each other and fell silent for a moment. Could it be that she was still asleep and dreaming?

"Who are you?!" Eriri #2 walked over from the doorway. Separated by a few desks from Eriri, the two Eriris looked like they were looking in a mirror when they were together. Even twins couldn't be this similar.

"Isn't this the question I should be asking!" After all, Eriri #1 had experienced the Holy Grail War and was quite knowledgeable, so she started speculating about conspiracy theories. "You! Who told you to impersonate me! Could it be that someone sent you to try and deceive Arthur?!"

“That’s impossible.” It was Kasumigaoka Utaha No. 1 who retorted to Eriri, holding out her right hand to show her the bright red Command Seal on the back of her hand. “Have you forgotten about the contract?”

Eriri choked and turned her head away.

She forgot this point in her haste. With the contract in place, even if they are twins, the Servant cannot fail to recognize the Master. Otherwise, the Nakano Five Sisters are quintuplets, so how could Oda Nobunaga mistake them?

"I know without you reminding me."

Eriri No. 1 tried to save face, but it was also true. Even without Kasumigaoka Utaha, he would have realized it sooner or later, just a beat slower.

Next, Eriri tried using a Command Spell, but it was a complete failure... Her expression changed, but she quickly returned to normal.

"Now is not the time to spread your unbridled tsundere attitude, Sawamura-kun."

Kasumigaoka Utaha No. 1 stood up, wearing black stockings, her ordinary school uniform stretched beautifully by her voluptuous figure.

Her voice is not loud.

"Your brain isn't entirely focused on arguing with me, is it? So, you've been a princess before, can't you see the current situation?"

"I know!"

Eriri No. 1 growled, but compared to her previous confrontation, she was much more restrained.

The experience and growth she gained during this period were not in vain, and she naturally had her own judgment.

"If I'm not mistaken..."

Eriri #1 maintained a calm expression, her voice kept low to ensure the other Eriri couldn't hear her. Even if she didn't want to admit it, Eriri knew that Kasumigaoka Utaha was currently her only ally.

Because, barring any unforeseen circumstances, both of them have probably tried using a contract to contact Arthur and Charlemagne.

However... there was no response.

Eriri is no longer the girl who panicked when she lost Arthur. Or rather, when Arthur was around, she would habitually rely on him and become childish and naive. But when Arthur was gone, her inner resilience would prevail after she had been tempered.

She subconsciously maintains the composure expected of a princess, so she is unusually calm and clear-headed right now.

Kasumigaoka Utaha No. 1 followed up with her words.

"...We are no longer in the same world."
