Five-year-old Tohno Akiha had received an elite education from Tohno Shinkyu since birth. As seen when Tohno Shinkyu previously ordered her to copy the Family Rules 100 times as punishment, Akiha, at five years old and not yet formally enrolled in school, had already mastered language and writing, putting her far ahead of her peers.
Regardless of how elite her education was, she was ultimately just a five-year-old girl. During the previous earth-shaking commotion throughout the Tohno Mansion, she was so terrified she thought it was a real earthquake, wrapping herself in a quilt and shrinking under the bed, trembling. The subsequent roars, gunshots, and sounds of fighting completely erupted. The maid normally responsible for taking care of Akiha turned pale, as if she had seen a ghost, and lost her nerve. She locked the door and used all the movable heavy objects in the room to barricade it.
"Miss! Out—outside there are Yōkai! Please! You absolutely must not go out!"
Tohno Akiha was stunned. Yōkai? Wasn't that just a trick adults used to scare children? The Tohno Family never went in for that sort of thing. But judging by the appearance of her maid, it didn't seem fake at all.
"Yō—Yōkai?"
"Yes! It was huge, crawling on the ground, with skin red like blood, horns on its head, a red face, and fangs! Many people were killed by it!"
As she spoke, the entire Tohno Villa experienced another series of violent tremors, causing many of the ornaments and decorations placed in Akiha's room to fall directly to the floor.
"What's going on?! Is someone fighting that monster?!"
"Miss, when I saw that monster clinging to the pillar just now, there was a lady in a black trench coat standing below, confronting it. And, and that lady in black who was confronting the monster, she looks very much like you, Miss, as if... as if she were your elder sister."
"Huh?!" Tohno Akiha was thoroughly startled. "But, but I only have one older brother. Where would an older sister come from?"
"Miss, do you think it might be that the Master had..."
"Ritsu!"
Akiba glared coldly at her maid, who immediately lowered her head in apology, realizing her slip of the tongue. No matter what the master did, no matter how controversial, it was not for the servants to discuss.
But why would anyone think Rin and Akiba were so alike? This was Rin's biggest asset in daring to impersonate Tohno Shinkyu's illegitimate daughter, because Tohsaka Rin and Tohno Akiha were cast from the same mold!
In this Nasuverse, Tohsaka Rin, Tohno Akiha, and Kokutou Azaka were all designed based on Aozaki Aoko as the prototype.
If we use the analogy of God creating humans, it's as if God made a mold of Aozaki Aoko, poured out a human form from it to create Aozaki Aoko, and then used the same mold to pour out the prototypes of Tohsaka Rin, Tohno Akiha, and Kokutou Azaka. They might be different from each other, separated by vast distances, and in their original timelines, they were never meant to meet.
When Rin and Aoko met, an indescribable sense of resonance arose between them, as if another self was standing before them. They were like sisters, transcending bloodlines; at their root, they were sisters.
And this feeling was not just between themselves, but also extended to others around them. Aozaki Touko believed Rin so easily because subconsciously, she felt Rin was her younger sister. Rin in front of her was like Aoko in front of her, and because of this, Aozaki Touko unconditionally trusted Rin to take good care of Aoko, her trust in Rin even surpassing that in Alice, a good friend she had known for over ten years.
At this moment, Tohno Akiha's maid was the same. When she saw Rin, who had come downstairs to confront Tohno Shinkyu, she subconsciously thought Rin was Akiba's older sister. This feeling was the most powerful invisible evidence!
After the roar of battle had ceased for some time, Akiba's door was knocked upon.
"Knock, knock, knock, Miss Akiba, are you there?"
A female voice she had never heard before came through. Tohno Akiha and her maid Ritsu exchanged puzzled glances. Finally, Ritsu, as the maid, went up and moved the heavy object blocking the door. Opening it, a young woman dressed in black, with a blood-colored Rose Group armband sewn on her right arm, stood at the doorway.
"You are?"
"I am Asuna, one of the squad leaders of the Rose Group. Big Sister has asked Miss Akiba to come downstairs."
"But downstairs..."
Asuna said with a somewhat solemn expression, "The monster has been killed by Big Sister, but Patriarch Shinkyu was attacked by the monster and has passed away."
"Thump, thump, thump, thump." Before the maid could reply, Akiba, disregarding her appearance, ran out directly in her nightgown, passing through the gap between Asuna and Ritsu, and dashed straight for the stairs leading downstairs.
"Ah! Miss."
Rounding the corner of the stairs, Tohno Akiha saw a group of people in black standing in a corner of the devastated hall. Her father, Tohno Shinkyu, was sprawled on the ground, a claw-shaped hole torn open in his back near his heart. His heart was gone.
"Father!..."
Five-year-old Tohno Akiha pushed away the crowd surrounding the "corpse" without hesitation, tears streaming down her disbelieving, childish face.
In Tohno Akiha's heart, unaware of the full truth, Tohno Shinkyu had always been just a stern father. She had not yet encountered any family interests, the ugliness of human hearts, nor had she ever recognized the filth and darkness hidden behind the Tohno Family. At this moment, she was merely an ordinary rich young lady.
Just a short while ago, her father, who had scolded her and punished her to copy the family rules a hundred times, was now... Enhanced: Acting ability.
"Boom!"
Rin punched the wall. An entire wall instantly cracked into a large network of fissures under Rin's single punch.
Those who witnessed this scene immediately broke out in a cold sweat. Although the members of the Rose Group had always known their Big Sister was very powerful, they hadn't realized she could be this powerful. Seeing the effect of that small hand, which usually hit them for big or small reasons, now smashing into the wall, they immediately understood how much Big Sister had held back when hitting them!
