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

Filled with inexplicable resentment, Mordred attacked the old sword.

The chaotic slashing, even incorporating punches and kicks during the swordplay—such barbaric swordsmanship would be unbearable for anyone encountering it for the first time, likely putting them at a disadvantage.

However, the Silver Knight, clearly a Saber-class Master, acted as if they had fought countless times. Even while holding his Master with one hand, he easily deflected Mordred's attacks with his holy sword with the other.

Unable to break through after a prolonged assault, Mordred's attacks became somewhat disorganized, and the Silver Knight seized an opening, forcing him back several steps.

Mordred's chest heaved rapidly. Despite being a seasoned Knight of the Round Table, she outwardly displayed anger, her mind racing as she frantically tried to discern the identity of the person before her.

Who is it? Why does it know her so well? Mordred was completely baffled.

"Mordred, your fighting style is still as ruthless as ever." The Silver Knight admonished in a tone like that of an elder, "I've said before that your fighting methods are problematic."

Mordred couldn't calm down and became even angrier; her father had once said those words to her.

"Shut up! Who do you think you are, lecturing me like that!" Mordred retorted without thinking; apart from her father, no one could discipline her!

"Eri, is it okay?" Arthur asked softly.

Eriri rested her head on the knight's chest armor, and even through the cold armor, she could almost hear his burning heartbeat: "Do what you want to do, Saber."

The mysterious knight reached out and removed the hood that covered his face, revealing a handsome and dashing appearance.

"How can it be……"

Mordred instinctively deactivated her Noble Phantasm, "Helmet that Conceals Infidelity," revealing her face.

The two stood facing each other, just like looking in a mirror.

With the same blonde hair and blue eyes, and strikingly similar appearances, Mordred's features are slightly softer because she is a woman.

"It really is a girl?!" Eriri exclaimed in surprise. Wasn't Mordred King Arthur's son? She had been wondering about that for a long time.

Lion Jie Li was so startled that he dropped his cigarette.

Normally, Mordred, having stepped on a landmine, would have already taught a lesson to anyone who dared to question her gender with the Radiant Sword of the King of Light. But now, she wasn't in the mood.

"Are you humiliating me?!" Mordred thought it was a Noble Phantasm that could change appearance.

"Even now, you still won't admit it?" Arthur said calmly. It has to be said that the unfilial son and daughter are exactly the same.

"Compared to you, you're a Heroic Spirit from another timeline, since my Mordred is male."

“Saber, Arthur Pendragon.” The knight king from another world held the holy sword before him. “Come, Mordred, let me see what I, from another world, have taught you.”

Is it Arthur?

Is it my father?

An uncontrollable rage surged from her chest, Mordred's beautiful face contorted in rage, and a violent burst of magic erupted, the crimson lightning echoing her emotions and soaring into the heavens.

Even if he is the King of Knights from another world, he is still the King of Knights.

Look at that condescending, lecturing tone and disdainful attitude. It reminded Mordred of King Arthur on her side, who had the same expression when Mordred eagerly revealed her identity, completely unconcerned and dismissive—

“I am not prepared to acknowledge this, nor will I entrust the throne to you.”

In King Arthur's eyes, Mordred was not the successor she desired.

At this moment, the shadows of King Arthur from another world and Artoria overlapped.

"Arthur—"

Extreme resentment caused Mordred to lose his mind.

"This is troublesome." Shiki Jie Li hadn't expected that he would be caught in a deadly battle as soon as he summoned the Heroic Spirit.

"King Arthur? What a remarkable heroic spirit."

In Europe, only a few heroic spirits, such as Hercules and Charlemagne, can rival King Arthur in fame.

Is he... a Servant from the subspecies Holy Grail War? Despite his rugged appearance, Shishi-kai is actually quite perceptive and intelligent. He guessed that Shishi-kai couldn't wait to participate after hearing that the orthodox Holy Grail War had begun.

The Master is nothing to fear, just a little girl, but that Servant…

Must it end now? Honestly, he might not even lose.

Shiki-kai saw it clearly: even though King Arthur was a notch above Mordred, he still had to consider the Master in his arms, and was thus constrained at every turn.

If nothing unexpected happens, that Master is just an ordinary person, and is King Arthur's greatest weakness.

"Hey, little girl."

Shishikatsu Kairi pulled out his hunting rifle, the dark muzzle pointing at Eriri: "Admit defeat. This kind of cruel war is not something you should participate in. You will really die."

Perhaps it was Eriri's age that reminded him of his deceased adopted daughter. Shishikatsu Kairi gave her a rare, well-intentioned warning. After all, he could tell from her demeanor that Eriri had never had blood on her hands, didn't know any magic, and was just an ordinary person.

Arthur also sensed the threat from the Lion's Robbery, but Mordred's frenzied and reckless attacks prevented him from protecting Eriri for the time being.

Eriri hugged Arthur's neck tightly and shouted, "I won't give up! Saber will protect me!"

This is something Eriri has always firmly believed in and has never wavered from.

"She's still just a little girl, as expected." Shishikatsu Kairi clicked his tongue, adjusted his aim slightly, and planned to hit Eriri's arm first.

After all, even if Eriri were killed in one blow, King Arthur's counterattack would be terrifying. It would be better to force them both to surrender. In any case, Eriri is different from those magicians and is really not a threat. That's what Shishikai Kairi thought.

"Stop, Lion Robber."

A red magic circle enveloped the Lion's Tribulation Realm.

The newcomers were none other than Makoto Aoki and Taiko-no-Wang. Although they were quite far away, they arrived at the scene much faster thanks to their escape techniques.

A magnificent golden ship hovered in the sky, and Gilgamesh had arrived.

Clearly, this Mr. Wang had no intention of getting involved; he was merely observing this "family tragedy" with great interest.

"I see, so it was a group operation? Looks like it was premeditated." Shishikage Kairi wisely put away his hunting rifle. He wasn't arrogant enough to compete with Heroic Spirits in speed. He reached into his pocket and asked, "Can I have a cigarette?"

Makoto Aoki nodded.

Lion Jie Li lit a fire for himself, took a deep breath, and exhaled a smoke ring.

"Let's do it." It wouldn't be bad to have a puff before I die.

"No, as a reward for not killing Eriri, we will not harm your life either." Makoto Aoki did not have the habit of killing innocent people indiscriminately. Besides, in the original work, Kairi Shishikai was very charming and was one of the few magicians who was not so scum.

Shishikage Kairi shook his head: "Being soft-hearted will lead to great losses." Those magicians will not show you any mercy. In Shishikage Kairi's opinion, even if Aoki Makoto and Eriri have powerful Servants, they are just children and have no chance of defeating those ruthless magicians.

As for him, losing is losing, and dying in the Holy Grail War is a good ending; he just didn't expect it to be so hasty.

Makoto Aoki shook his head: "I won't change my mind."

"Of course, in order to avoid leaking our information, please have Lion Robber sleep quietly in a secluded place for a few days."

"When I wake up, the Holy Grail War will be over."

"Aren't you going to force me to order my Servant to commit suicide?" After all, Shishikage Kairi still has a complete three-stroke Command Seal, which even Saber, who has a strong magical resistance, cannot resist.

"There's no need, they're almost done on their end."

Makoto Aoki looked at the battle between Arthur and Mordred, which was nearing its end.
