I'll kill you after I finish this game!

Due to his individual strength, Reiji had no interest in participating in the Holy Grail War.

In this world where there are countless parallel universes, there is a group of mischievous magicians who will stop at nothing to pursue the truth.

The so-called Holy Grail War is a convenient ritual they created in order to pursue the elusive 'Root'.

Using the magical power accumulated over decades by the ley lines of Fuyuki City, they dragged down great heroes from the Hall of Heroes, which is recorded in history, to become higher-level familiars.

Seven Heroic Spirits will fight their Masters in pairs, and the sole victor will gain the right to enter the Root of the World and glimpse the truth of the world.

During the Fourth Holy Grail War, Reiji had no interest in the corrupted Holy Grail. He merely observed the so-called Holy Grail from the sidelines and then continued doing what he was supposed to do.

As for getting to the root of the problem, it is indeed very attractive to Raiji, but doing so would attract the attention of a certain annoying guy.

Regardless of success or failure, Razer's sense of touch could no longer remain in this world, so he had no choice but to give up.

At this very moment, in the mansion of the Tosaka family, a prominent family in Fuyuki City.

Sakura Tohsaka, a girl somewhere between a young girl and a loli, is making lunch in the kitchen while wearing a pink apron.

Sakura is a beautiful girl with outstanding looks. Her bright long hair and gentle, healing smile give her an unusual sense of maturity.

Although she is still quite young, her figure already reveals the maturity she should have in the future.

Because she learned a magic trick left by a benefactor, Sakura's hair and pupils changed to a beautiful light purple color.

"Slurp... Hmm, that's about right."

Sakura smiled faintly, picked up the spoon, took a small sip of the rich soup, nodded in satisfaction, and then prepared to serve the meal.

"Tuk-tuk-"

As if she could smell the rich aroma from the kitchen, crisp and hurried footsteps reached Sakura's ears.

"You're trying to steal a bite, aren't you?"

"Hmph, is this what those countries over the sea call 'the thief crying 'stop thief''?"

Before the person even arrived, Sakura heard a heated argument, speechless. She put the pot lid back on, turned her head expressionlessly, and saw two girls who hadn't yet reached the stage of girlhood pushing and shoving each other.

The girl, with her pigtails tied with black ribbons, blue eyes, and wearing red clothes, had an air of haughty sullenness.

Rin Tohsaka, her still-childish face sulking, reached out her little hand and pressed it against the fair cheek of the silver-haired girl in front of her.

The girl had long, slightly wavy silver hair and pure golden eyes. She had fair skin and a petite figure, and her whole being was like an exquisite painting.

Although she herself was not very old, the peaceful and serene atmosphere emanating from the other person added a touch of mystery and mature charm to her.

Even with her cheeks pressed down, the silver-haired girl, Kallen, maintained a calm and expressionless demeanor. However, the Shroud of Resurrection wrapped around her waist was tightly bound to Rin Tohsaka's arm under her control.

The atmosphere between the two seemed quite confrontational, and Sakura Tohsaka was slightly troubled by this scene.

"How dare you be so rude in my own home!" The still immature Rin Tohsaka was furious, and her long, beautiful legs stomped her feet in response to her emotions.

Kallen looked at Rin Tohsaka with a sneer, still sharp-tongued, and said, "You can't even take care of yourself at home, yet you spend so much money and jewels practicing magic every day. Who do you think bestowed these gifts upon you?"

"you..."

"Alright, sister, stop arguing with Karen, or you won't get any food today!"

Sakura Tohsaka had had enough of these two clowns causing trouble, so she directly issued a verdict targeting their fatal weaknesses.

Upon hearing this, the two men's expressions changed, and they immediately released each other, apologizing politely, saying, "I'm sorry!"

"Come over here and serve the dishes, and don't you dare sneak a bite!"

Despite her young age, Sakura Tohsaka acted like a very dignified little adult, urging him on.

The two obediently went to serve the dishes, but during the process, their eyes were constantly flashing with a subtle, antagonistic tension.

At the dining table in the living room, a mature woman wearing medical goggles, with a face that was very similar to Karen's and a somewhat thin and sickly figure, came down the stairs from the second floor, leaning on the handrail.

"Mom, why did you come downstairs alone!"

Upon seeing the woman, Karen immediately put down what she was holding on the dining table and then rushed anxiously to her mother to help her up.

Seeing Kallen run to her mother, Rin Tohsaka's eyes flashed with envy and loneliness. She envied that Kallen, the sharp-tongued girl who was always at odds with her, still had her own family.

Her father had already sacrificed himself in the Fourth Holy Grail War, and her mother fell ill after receiving the devastating news.

It was that blond, kind man named Kirei Kotomine who was helping her, but Rin Tohsaka always felt that the smiling priest was emanating a creepy aura.

Fortunately, the other party was always away on long trips, so they didn't see each other very often.

Sakura Tohsaka didn't show much emotion when she saw this scene; she just looked at Kallen with a sense of reminiscence in her eyes.

When she was little, she almost fell into an abyss, and it was the blond man holding Karen's hand who saved her.

After the Holy Grail War ended, she was placed with her sister and placed in Claudia's care.

Although she once resented her father for pushing her into the abyss, now that he's dead, what else can she say?

"Karen, I'm just weak, but I'm fine." Karen's mother, Claudia Ordesia, gently stroked her daughter's head with a warm smile to show that she was alright.

Karen's mother, Claudia, has albinism and a weak immune system.

Therefore, even minor injuries can bring one to the brink of death, leaving the body riddled with wounds—a condition that cannot be described simply as weakness.

So when Karen heard her mother's words, the blank expression on her face vanished, replaced by a strange displeasure, and she said:

"Why didn't that man cure your body, Mother? It was clearly no difficult task for him."

"Karen!!"

Hearing her daughter's complaints, Claudia's gentle face suddenly turned stern. She lightly tapped her daughter's head and lectured her:

“Your father, you, and I have all received a great deal of kindness from that man. You are not allowed to say such things again. I did not raise you to be the kind of person who takes other people’s kindness for granted and does not know how to be grateful.”

She was indeed physically weak, but her husband, who had undergone a complete transformation, had already gone to find a way to treat her.

Compared to before, Karen and she can be considered happy because they are constantly working hard.

It's putting the cart before the horse to rely on favors to make yourself happier; happiness is something you have to pursue yourself.

Moreover, the other party did not cure her; it was actually her husband's wish that he could cure his wife through his own efforts.

Claudia, Kirei Kotomine's wife, knows that he is simply enjoying the process of saving his wife's hard work and effort.

Although her husband has become a bit more carefree after his transformation, it's a huge improvement compared to his previous lifeless state.

"Um...I was wrong."

Faced with her mother's unusually stern demeanor, Karen pouted and bowed her head in apology.

Claudia looked at her daughter, who resembled her in every way except for her face, and sighed inwardly.

Her daughter does resemble her husband quite a bit, but thankfully she doesn't seem to have a significant lack of personality and emotions.

"Om-"

Suddenly, a divine energy burst forth from Karen, and strange, divine golden patterns appeared on large areas of her body, including her arms, neck, and forehead.

The strange holy mark seemed to pulsate like a heart.

"Well..."

Karen's face turned pale instantly, and she raised her hand to clutch her chest. The symbol of the Holy Cross also appeared deep within her golden eyes.

Aside from the pain on her face, Karen also exuded a sacred aura, as if a saint were suffering.

"Karen!" x3

Claudia, Sakura, and Rin all looked anxious and immediately helped Kallen, who was in pain, to prevent her from collapsing to the ground.

"These are... Stigmata? There are so many!?"

Rin Tohsaka stared in disbelief at Kallen, who was curled up and hugging herself.

This was the first time she had seen Kallen like this. Her knowledge of magic also allowed her to recognize the golden markings on Kallen's body that resembled Command Seals.

There are only one or two Stigmata constitutions at most, how could there be one like Kallen with them covering her entire body?

And the eyes that changed on the other person, they must be demonic eyes, right? They must be demonic eyes!

Sakura Tohsaka raised her hands, intending to use a simple healing spell, but the magical energy was instantly annihilated as soon as it approached Kallen.

"Karen, how are you feeling!?"

Claudia held her daughter anxiously, but the active divine energy emanating from Karen did not resist or reject her.

Karen, held in her mother's arms, was pale and somewhat distorted, her voice trembling with suppressed pain as she replied:

"It hurts, but the pain is gradually getting used to and lessening, it's okay."

While in her mother's arms, she saw a golden vortex suddenly open in the living room, and the reflection of a person in it. Her consciousness also fell into a coma due to the pain.

.........

Karen considered herself unfortunate and believed that her life was just like that.

She seemed to have inherited her father's traits; her natural emotions were corrupted.

She was born in a republic in southern Europe, and her mother, Claudia, "died" a year after her birth.

Then, abandoned by her father, she was temporarily adopted by a man who seemed to exist only in myths or novels, a man who appeared radiant and dazzling in her memory.

One reason why she was so impressed by this man was that her Stigmata awakened when she met him, and the pain that came with that awakening is something that Kallen still finds hard to forget.

That man taught Karen a lot and fulfilled the responsibilities of an adoptive parent.

Although the initial meeting was somewhat painful, Karen genuinely enjoyed their life together afterwards.

She loves the food he cooks... because it makes her feel happy.

Because of her innate lack of emotion, she experiences very little happiness. Seeing her peers laughing and grieving over various things, Karen feels curious and envious.

Curious about the emotions the other person can feel, envious that the other person can be like a normal person.

From a young age, she was very passive and honestly endured everything.

However, it is also because of this personality that I see the normality of my peers.

Karen also developed a cruel and intense desire to "destroy the happiness of others and expose their inner traumas."

That's precisely why she can be so sharp-tongued.

The man, who called himself Rei Zhe, saw through her desire and asked her with a smile, "Does destroying other people's happiness give you pleasure?"

What kind of question is this? Does it bring pleasure to destroy someone else's happiness?
