Shirou, who returned from the Fairy Kingdom

Although she could barely hold on until Shirou used his third "Command Spell," it was impossible to expect her to fight alongside her Master as usual.

So she sent Shirou to Ryudou Temple alone, while she stayed on the steps to rest.

She wanted to preserve her last bit of life force so that Shirou could unleash his final "Royal Command Spell" when facing Saber later.

"This is truly goodbye... 'My Arthur.'"

The female magician gazed weakly at the red-haired boy walking towards Ryudouji Temple and murmured.

"I'm sorry, I made a big promise to you. I really can't be as dashing as Morgan and stay with you until the end... I'm so unwilling to accept it."

However, this can't really be considered desertion before the final battle, so let's forgive them.

Ms. Avalon slowly closed her eyes.

A smile played on her lips.

"Good luck in the Holy Grail War to come, Master..."

"I've changed my mind and decided not to use the third 'Royal Command Spell'."

"…………Master!?"

Lady Avalon opened her eyes in surprise to find that Shirou, who should have left, had returned and was standing in front of her.

Shirou approached her, placed his hand horizontally on Lady Avalon's abdomen, and then emitted a soft green light.

"This is a healing spell... Master! At a time like this, don't waste your mana on me!"

Shirou said seriously, "Rather than using the 'Royal Command Spell' to defeat Saber, I'd much rather work together with Avalon to defeat her."

"Even if Master heals me, I still don't have enough mana left to fight Saber! So, let's use the 'Royal Command Spell'!"

Ms. Avalon said in a stern tone.

Hearing her say that, Shirou frowned slightly: "Big sister Avalon, do you have self-destructive tendencies?"

"...I just don't want you to say that."

Shirou said, "I'm not someone who thinks about self-sacrifice all the time, am I?"

I'm more selfish than anyone else, just like you—"

As he spoke, he picked up the female magician.

Given Shirou's child-sized size, it would be very difficult for him to lift up Ms. Avalon, who is an adult.

Fortunately, Ms. Avalon only weighed 20kg, which was lighter than Shinji, so Shirou easily picked her up.

"Big sister Avalon, self-sacrifice is not suitable for you. Living to the end with a sense of pride is the kind of teacher I know."

"!"

The word "teacher" made Merlin's eyes widen.

She looked at Shirou and found that he was also looking at her with a meaningful gaze.

"........."

Ms. Avalon blushed immediately.

Even she herself didn't know why, but her cheeks felt hot as if she had a fever.

After a brief mental breakdown, she struggled violently.

"Let me go! Master! I'm really getting angry!"

Ms. Avalon's two long, beautiful legs were flying up and down in mid-air, but Shirou ignored them and forcibly carried her to the woods nearby.

Lady Avalon's injuries are twofold. One is at the Spirit Origin level, which Shirou is helpless to address.

As for the remaining physical injuries, Shirou healed them with magic, but this also exhausted the magical power he had gained from drinking the anti-aging potion.

"...What have you done?"

Ms. Avalon covered her forehead and sighed helplessly.

"Even though we're about to have our final battle with the enemy, I've wasted all my last bit of magic power."

"So, how exactly are we going to fight the enemy next?"

Shirou scoffed, "I can't just stand by and watch Lady Avalon die... I'd have nightmares."

Lady Avalon rolled her eyes: "Master...you should have already noticed, right?"

Shirou blinked: "What?"

"Stop playing dumb... You clearly called me 'teacher' just now, didn't you?"

Shirou nodded: "Yeah, because I had a strange dream... In the dream, I became the disciple of Big Sister Avalon."

When she realized that Master had lost his memories of Britain, Lady Avalon decided to keep those memories a secret until the very end.

Because she felt she wasn't the one who could save the child.

Even if Arthur learned the truth from a monster like himself, he certainly wouldn't be happy.

In the Holy Grail War, masters and servants with particularly good compatibility can learn about each other's experiences through dreams.

Although Lady Avalon can enter human dreams, she cannot completely manage them.

She could only hope that she and her Master weren't that compatible... but unfortunately, they were far too compatible.

Shirou probably dreamt of memories of Britain.

“…………Alas.” Merlin sighed softly.

Why are you always sighing?

"Who do you think caused this?"

"Feel sorry."

"Master has no need to apologize."

Lady Avalon shook her head: "Now that things have come to this, we can only defeat Saber with the strength of the two of us."

"Yes, that's what I planned from the beginning."

Seeing Shirou's piercing gaze, the Flower Magician's cheeks flushed slightly.

Waaah... Don't look at me with those pleading puppy eyes!

"Yes, I know, I'll figure something out!"

"Oh my, she truly lives up to her reputation as the elder sister Avalon!"

Lady Avalon extended her right hand: "Master, extend your hand."

"Okay~ What are you going to do?"

Shirou craned his neck curiously, and heard her say something.

"Next, I will break down the 'Royal Command Seal' and exchange it for pure, colorless magic blocks."

Since the Command Seal system has been taken over by the enemy, you can't change "Royal Command Seal" back to a regular Command Seal. Just exchange it for magic power directly.

While it cannot be compared to the "Royal Command Spell," it is still an immense magical power—

That's enough for Master and me to fight Saber in a perfect state with our magic at its peak.

Shirou nodded, agreeing with the opinion.

Lady Avalon held Shirou's hands in her own, kneading the backs of his hands with her fingers while constructing a magic formula within his body.

"It's so itchy."

Lady Avalon frowned slightly: "Don't move, Master."

"…………sorry."

Shirou noticed that the black and red Command Seals on the back of his hand were gradually disappearing.

To be honest, he really enjoyed the feeling of turning back into an adult body... the sense of omnipotence was palpable.

But if this would deplete Lady Avalon's life force, he would rather remain a child.

Five minutes later, the last Command Seal on Shirou's hand disappeared.

"Hey Hugh, that's it... How's it going? Feeling anything?"

"Ok!"

Shirou nodded, looking at his chest. The magical energy obtained from the Command Seals was now stored in his heart.

"I feel a constant surge of energy emanating from my body."

While I can't compare to my "Royal Command Spell" state, I might be able to last a minute against Saber now!

Ms. Avalon's lips twitched: "We'll lose in a minute..."

"I just can't do anything with you~ Heh, well then, let someone else fight alongside you, Master."

Shirou exclaimed, deeply moved, "Oh, how reliable! Big Sister Avalon!"

"Alright, it's getting late, let's get ready to go."

Lady Avalon stood up and looked at her Master: "Master, please share some of your magic power with me."

"?"

Seeing Shirou tilting his head, Lady Avalon was even more puzzled.

"What's wrong, Master? Time is of the essence, I haven't obtained magic power yet."

I have very little magic left and am extremely weak, so I can't offer you any help.

"No, that..."

Shirou looked at the back of his empty hand.

Ms. Avalon seemed to realize something as well, her beautiful eyes widening in surprise—

When the last Command Seal was dismantled, Shirou's master-servant relationship with Lady Avalon also ended.

The magical channel between them disappeared.

Shirou: "…………"

Ms. Avalon: "…………"

The two blushed and looked away.

They also came up with a way to quickly supply magic.

Volume 1, Chapter 110: First Experience?

Speaking of which, Shirou only recently heard about a certain "shortcut" to replenishing magic power from Lady Avalon.

At the time, Shirou was struggling with how to provide magic to Assassin, so she mischievously whispered the method in Shirou's ear.

A man and a woman can establish a magical channel as long as their bodies are connected.

Male semen is the purest crystallization of magic.

These seem to be the most basic common sense in the world of magic, yet Shirou knows nothing about them—

Because Morgan hadn't taught him any of these things when they were in the fairy kingdom.

Although they hadn't taught him any of this, those guys somehow managed to get their hands on magic potions while Shirou was asleep, and they even got into a fight over them...

Looking back now, it feels really wrong.

"……Well!"

Shirou was somewhat confused. He glanced out of the corner of his eye at Lady Avalon, who had been silent since the beginning.

A faint blush rose on her small, delicate, and beautiful face, making her look even more radiant than usual.

Shirou felt inexplicably parched, and he quickly suppressed the agitation in his heart:

"By the way, Sister Avalon, you must know some magic... the kind of magic that allows you to draw magic from others?"

"Ah, yes, that's right."
