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

"Eri, your father is back. You need to explain things to us..."

Although Eriri brushed her off, Mrs. Sawamura, still harboring doubts, originally wanted to take this opportunity to press Eriri for the truth, but when she opened the door, she saw this scene.

The image of a knight king in armor swearing loyalty to a blonde girl immediately struck a chord with Mrs. Sawamura, a long-time anime fan.

How romantic! How wonderful! It would be even better if it were two men, as Mrs. Sawamura, a fan of BL (Boys' Love), screamed inwardly.

then……

"Eri--"

It would be better if one of the main characters wasn't her daughter.

“Your Majesty King Arthur!” Eriri’s father, Mr. Spencer, was in a frenzy upon seeing his idol, his face filled with a “I’d die happy” expression. He exaggeratedly knelt down, making a knightly gesture of allegiance, “Our King, Britain has been waiting for your return!”

“As Master’s father, you don’t need to perform such a grand gesture.” Yawei turned slightly to the side, avoiding Mr. Spencer’s gesture of allegiance.

"Master?!" Mrs. Sawamura wasn't like Eriri, who was illiterate in English. She covered her flushed cheeks. "It's actually playing Arugin's (Master's) game? How can it be so exciting!"

"Mom, what are you talking about?" Eriri asked, bewildered. "What do you mean by 'master'... wait, does 'master' actually mean 'master'?"

The golden-haired girl's screams echoed through the sky.

“Master,” Arthur said helplessly to this broken family, “please calm down.”

"How am I supposed to stay calm?!" Eriri stammered, her cheeks flushed crimson. "W-why does he call me master?" Does Arthur have some strange fetish?

If that's the case... Faced with Arthur's handsome face, clear eyes, and the added advantage of being King Arthur, Eriri covered her head in dismay. What should she do? If he called her master, she could totally accept it!

It's over, she's fallen!

"...Given the relationship between a magician and a servant, it actually means Master or Contractor," Arthur explained gently.

"Oh, I see. Haha, haha."

Mrs. Sawamura and Eriri were embarrassed by their misunderstanding; they were truly mother and daughter, their expressions were exactly the same.

Then we heard Arthur say the next thing.

"Of course, you can also interpret it as the master, which is perfectly fine."

The blond knight, whether naturally dark-skinned or not, had a smile that could almost light up the night: "After all, as the knight who protects his master, I can also explain it as a master-servant relationship, right?"

……

"Ah ah ah ah ah!!"

Eriri and Mrs. Sawamura were completely dumbfounded. How could someone say something like that so seriously? The point is, he is really, really, really handsome!

After everyone finally calmed down, Eriri clutched her heart, which was pounding so hard it felt like she was having a heart attack: "From now on, please just call me by my name."

Arthur blinked. "Why?"

"Stop talking nonsense! Don't you know this is bad for your heart?!"

Arthur nodded slightly: "Alright, Eriri."

Seeing that the way she addressed them was finally normal, Eriri breathed a sigh of relief, then stood up and formally introduced her parents.

“This one, cough, you all know him.” Eriri raised her eyes, her azure eyes showing a rare seriousness. “The knight who saved me, the hero who killed the sea monster, his identity is King Arthur of Great Britain. In short, we have already signed a contract, and I am his master.” When she mentioned her master, her cheeks began to burn again.

Fearing her parents would object, Eriri spoke first.

Even Mr. Spencer, a die-hard fan of King Arthur, had mixed feelings about this; it's true what they say, daughters grow up and leave home...

“Your Majesty King Arthur,” Mrs. Sawamura began.

"You can just call me Arthur, no need to worry about it." The blond king appeared very humble.

“Then… Arthur.” Even Mrs. Sawamura, who is usually quite unreliable, subconsciously used honorifics when addressing this world-renowned king. “Could you answer my question?”

"Please say."

"Why would you enter into a contract with my daughter?"

Even Eriri herself perked up her ears upon hearing this question.

"There are many reasons," Arthur said honestly. "I was short of mana, Eriri had good aptitude, the timing was right, and Eriri agreed to my request..."

Hearing the young man's serious words, the blonde girl's cheeks puffed up.

Damn it, can't you say something nicer?

"Of course, the most important reason is... I want Eriri to become my master, so that I can protect her without any distractions and as a matter of course."

The Knight King's smile seemed to melt into the light.

"what are you talking about!"

This is Eriri Sawamura, completely overwhelmed by the final straight shot.

"Is there a problem?" Arthur looked back at him naturally, thinking that his wording should be fine.

"No, it's nothing." Eriri moved away, damn it, it's too dazzling!

Mrs. Sawamura touched her chest. She was a high-level player! Even she herself was tempted by this charm, let alone Eriri.

She looked at her daughter with a complicated expression, making Eriri's scalp tingle: "What's wrong, Mom?"

"I just feel like I understand you now, Eriri." After all, even she herself couldn't resist this charm, so how could she possibly persuade Eriri?

"However, I have a crucial question that I would like to ask you, Arthur."

Mrs. Sawamura's eyes sharpened. She was a mother, and unlike Mr. Spencer, she didn't think about international repercussions or anything like Warcraft. All she cared about was her daughter.

"Excuse me!" Mrs. Sawamura exuded an imposing aura as she stared stubbornly at Arthur. "You will protect Eriri, right?"

Every woman is incredibly strong when she becomes a mother.

"meeting."

Arthur met Mrs. Sawamura's questioning gaze without flinching; his clear, sky-like eyes revealed his determination and resolve.

"I came into this world with a mission, but that doesn't conflict with my feelings."

"I swear by the sword in my hand, in the name of Arthur Pendragon."

"I will protect Sawamura Spencer Eriri until the end of my life."

Eriri... well, the blonde girl has completely lost the ability to speak; she's practically melting away.

While Mrs. Sawamura was overjoyed, she was also lamenting that, let alone advising Eriri not to participate in such dangerous activities, Eriri herself might have been willing to die even if Arthur took her with him.

“Your Majesty King Arthur… well, Mr. Arthur.” Mr. Spencer changed his form of address under King Arthur’s gentle yet unexpectedly imposing gaze, “You mean, something like what happened today will happen again, like that terrible sea monster?”

Mr. Spencer still feels lingering fear when he thinks of the Sea Demon, since modern firearms are completely ineffective against it.

“That’s right, it’s a disaster that no one can solve right now,” Arthur said firmly. “That’s why I’m here.”

"Wouldn't that be extremely dangerous?" Upon hearing this news, not only Mr. Spencer but even Mrs. Sawamura felt relieved. Fortunately, Eriri had made a pact with King Arthur, so at least their family had King Arthur's protection and wouldn't lose their lives like those other people.

"That's right, it's currently limited to Japan, but such disasters will continue to occur, and the affected area may continue to expand."

"What can we do then?" Mr. Spencer's hands and feet were ice-cold. "How can you solve so many problems all by yourself?"

"To be honest, other Heroic Spirits have already appeared."

Arthur said seriously.

"The Heroic Spirits who helped me before, and who dispatched familiars, are probably either Casters or Archers, if nothing unexpected happens."

From this very distant place, the black-haired heroic spirit sneezed.
