My youth story, a crossover anime, turns out, is FGO!

(This chapter was mistakenly posted as a future draft, but I can't delete it, so I'll have to replace it with an extra chapter. This is probably an extra chapter that will be written in the future, when the Dragon and Tiger of this story meet the Dragon and Tiger of the original work.)

“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 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.

Eriri glanced at her: "Me too."

I actually have the same idea as this guy! x2

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.

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, "Y-you, who are you? Are you a doppelganger? Or some kind of monster?!"

"You're the monster!" Eriri roared in anger.

"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 black eyes.

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. The two Eriris stood together, looking like they were looking in a mirror. Even twins couldn't be this similar.

"Isn't that 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, you're not one of those people sent to deceive Arthur, are you!"

“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.
