A certain crossover anime's nuclear-powered sword immortal

Humans are too fragile; if they were to use divine power carelessly, they might destroy her outright.

The reason it was used on Princess Alice before was because she was the strongest witch in the world and could withstand divine power.

After Shirou used healing magic, the girl's pain gradually subsided, and at least for the time being, she would not experience any spiritual disturbances.

"almost……"

Muttering to himself, Shirou stopped casting the spell, walked to the window, and gazed at the city outside.

It rarely snows in Fuyuki City.

This gloomy weather looks more like it's going to rain.

As expected, just as Shirou predicted, the city experienced its first rain of winter.

It was a light drizzle carried on a gentle breeze, barely making a sound as it pattered against the glass.

The city outside the window was shrouded in a hazy mist.

The rain was whipped up by the wind, slapping against the glass in waves.

The city's outline became distorted by the refraction of the ripples, and the extensions of houses and streets bent and deformed, no longer as orderly as before.

The dark sky was reflected in the pool of water that had accumulated on the ground.

"Uh... um..."

A muffled groan suddenly came from behind him, and Shirou immediately turned around upon hearing the sound.

Wearing a nun's habit, Karen Aldesia's eyelashes trembled slightly as she slowly opened her amber-like eyes.

Karen stared blankly at the gray ceiling for a while. It seemed like she was having a dream. She dreamt that when she was leaving the church to throw away the trash, a ghost suddenly appeared, and then, in her dazed state, she was carried away by a man.

Wait... I've been carried away...?

A bad thought suddenly flashed through Karen's mind, and she quickly sat up and looked at the clothes she was wearing.

She was still wearing her black and white nun's habit, though it was now a little wrinkled.

"Phew..." The clothes are still on my body, so it seems I haven't been treated strangely.

Karen breathed a slight sigh of relief upon realizing this.

"You're awake." A man's voice suddenly reached Karen's ears.

Upon hearing this voice, Karen tensed up immediately and quickly turned to look.

He was a tall, slender young man wearing a loose black casual jacket and matching trousers. He exuded an invisible sense of pressure, a feeling that Kallen only saw in those who had been in high positions for many years.

His face was also very handsome, with rare light gold eyes, a slightly upturned mouth with a gentle smile, and some messy red hair that partially covered his eyes.

"What on earth are you...?"

Karen looked at him with some confusion.

Because she realized that her body was not being treated cruelly, Karen did not feel much fear, believing that this person would not do anything too evil to her.

"My name is Orihara Shirou, and I guess you could call me a magician. I saw you suddenly faint earlier, so I treated you."

Upon hearing the man's answer, Karen's eyes widened slightly.

Then, she lifted her sleeve and stretched out her fair arm to examine it.

"The wound... is gone...!"

It was obvious that she knew how troublesome her "masochistic medium" status was, and if she had collapsed there, she didn't know what kind of situation she would have ended up in.

"Thank you for your help, Mr. Orihara!" Karen quickly got off the bed, clasped her hands together, and bowed respectfully to Shirou.

Clearly the other party

Zhang's young face didn't look much older than her, but the other person's unspoken aura gave Karen a strange feeling of facing an elder, so she subconsciously addressed him that way.

"There's no need for that. After all, it was because of me that you ended up in that state." Shirou smiled and helped her up.

"Eh!?"

"You mean... I entered a state of mental disorder because of you!?" Karen felt her mind becoming confused again, and her breathing became rapid.

Suddenly, she felt that the man in front of her with the gentle smile was not as safe as she had imagined.

"So that means... Mr. Orihara, are you a demon?"

“No, that’s not it…it might be for other reasons…” Shirou said, resting his chin on his hand, after a moment of consideration.

Even demons would be terrified if they saw him.

"This……"

Although she no longer experiences any spiritual disturbances, Karen still vividly remembers the pain she felt when they occurred.

After arriving at the church here, she encountered a 'demon' once. It was a woman possessed by a 'demon'. Karen, who was in this situation for the first time, had no idea what to do and was almost injured.

Fortunately, her grandfather, Kotomine Risuke, removed the 'demon' from the woman, so Karen was not harmed and only suffered minor wounds due to the spiritual barrier.

But since then, she has also come to understand the kind of pain that her seemingly cursed constitution would bring her after she unfortunately encountered a 'demon'.

After glancing at the clean white sheets behind her, Karen hesitated before speaking.

"I wonder if I may leave now, Mr. Orihara..."

Karen silently prayed, hoping the man didn't have a penchant for imprisonment.

"Of course, you can leave at any time, but I think you can wait a little longer, because it's raining outside right now."

Upon hearing this, Karen also turned her gaze to the window, looking at the city amidst the wind and rain.

"Is this so..."

Karen bit her lip slightly and nodded.

"Then I'll trouble you for a moment."

“Of course.” Shirou smiled and nodded, then turned back to look at the street, waiting for the two people to arrive.

Karen sat somewhat awkwardly on the edge of the bed, tentatively looking around.

Suddenly, she remembered something.

"By the way, Mr. Orihara, what you just said about healing my body?"

"Yes." The man continued to look out the window without turning around, as if there were things more worthy of his attention than the beautiful silver-haired girl.

"So... I'll turn back into my original form soon, right..."

A hint of disappointment flashed in Karen's eyes.

Once the effect of this secret technique wears off, her 'curse' will return.

Even if she doesn't have to enter that bleak world of magic in the future, her life will still be full of twists and turns.

But there's nothing she can do about it; she was born with this constitution, and this is probably her fate.

Chapter Four: Reunion with Sakura

While Kallen was feeling down, Shirou, who had been watching the window, suddenly spoke up.

"You specifically asked me about this because you hope there's a secret technique that can stop your spiritual obstacles from recurring?"

"Yes, if I could, I really wish I didn't have such a 'curse' in my body."

Karen frowned slightly, her tone tinged with sadness.

This constitution means her life is destined to be anything but easy and fulfilling; it will be filled with all sorts of pain that could appear at any time, which is no different from a curse.

"If you are willing to pay the price, I do have a way to change your physical condition."

Suddenly, the red-haired boy said this.

The sudden hope made Karen's eyes light up slightly, but then she suddenly noticed the 'price' in the other person's words.

Although she was a little scared, Karen decided to at least ask what the 'price' would be before making any plans.

"Mr. Orihara, could you tell me what the price is?"

Upon hearing the girl's question, the red-haired youth standing by the window finally turned around, his pale golden eyes, which seemed to carry a certain majesty, looking at her.

"'The price'... is this." Shirou raised a finger and tapped his lips: "To completely rid you of the power of the 'curse,' it needs to be transmitted through your mouth. Although there are other methods, I'm worried that your body can't handle it, and it might even cause you to collapse."

"This..." Although the price he paid didn't feel painful, it was still somewhat shameful.

Kallen frowned slightly, looking at Shirou with some concern.

"Are you really not lying to me? It's like when you see a beautiful woman you like and use sweet words to deceive her naivety."

“I can swear to the god you believe in that I can make sure you never experience any more spiritual disturbances. Your ‘curse’ will disappear as if it had vanished, and it will never have any impact on your life again.”

"

It's still uncertain whether the god the nun worships can defeat Shirou...

"..." Kallen wavered slightly.

Several minutes later, as if she had made up her mind, she pursed her lips, her cheeks slightly flushed, and closed her eyes slightly.

"If you haven't lied to me... please... please..."

Then, a few seconds later, the girl's lips were pressed together.

As if directly transmitted into the mind, the chanting of the Word of Power began to ring out.

When Shirou looked up again, the girl's cheeks were still flushed.

"Is it... over...?"

"Yes, it's over." Shirou smiled.

Karen quickly wiped her lips and then stood up.

"But... I don't feel anything..."

The girl looked at him with the same expression she had when she looked at him as if he were an evil man who had deceived an innocent girl.

"So what do you need to feel?" Shirou shrugged. "You probably heard it just now, the voice of the Word of Power. That is a kind of protection. Your constitution has been changed, and you will no longer experience spiritual disturbances."

Shirou did not impose the master-servant concept on the nun in front of him. He merely suppressed her "masochistic spiritual medium" in a protective manner, so he naturally did not have any special feelings.

"I always feel like you're lying to me..." Karen seemed to regret it a little and felt ashamed that her first kiss had been taken from her.
