Tohsaka Rin

Under the curious gaze of her sister Sakura, Rin Tohsaka half-forcedly dragged Shinji Matou to a secluded corner of the courtyard.

She carefully looked around, and after making sure that no one had noticed, the smile on her face quickly faded.

She put her hands on his hips, raised her chin, looked at Shinji coldly, and said politely: "Seaweed head, you know what we are here to do today, right?"

Seaweed Head, had this nickname appeared so early?

"I heard it from my father," Shinji Matou didn't mind the nickname Rin gave him.

Inside his young body was the soul of an adult, and he wasn't exactly young either.

He would not argue with a little girl..

"That's good; it saves me the trouble of explaining," Rin Tohsaka stepped forward and spoke in a forceful tone.

"Listen carefully, starting from today, Sakura is your sister. Let's get this straight: she is the dearest person to me. I've even thought that if I could take her place and be sent here instead, I would. If I ever find out that she's not treated well here or is being bullied by you, be prepared to get beaten by me!" Rin Tohsaka threatened, waving her little fists.

The little girl's purpose was quite similar to Shinji Matou's, who just smiled faintly, "You don't need to remind me. From today, she's my sister, and I will take good care of her, fulfilling my responsibilities as her elder brother."

"Really?" Rin Tohsaka seemed surprised by how easily Shinji Matou agreed.

She took a step back, her eyes fixed suspiciously on him.

Shinji calmly replied, "Absolutely."

Hearing this, she crossed her arms and huffed, "Though you look infuriating, you don't seem that bad. I'll give you the benefit of the doubt. To be on the safe side, let's make an agreement."

"Promise?"

"Extend your right pinky finger."

"Like this?" Matou Shinji stretched out the little finger of his right hand.

Tohsaka Rin also stretched out her right little finger and hooked it together, speaking seriously, "Repeat after me: 'Anyone who lies must swallow a thousand needles.'"

The boy chuckled and repeated, "Anyone who lies must swallow a thousand needles."

"Very well, the pact is established. Hmph, I've already used magic in this agreement. If you break your promise, be prepared for your bad luck! I won't forgive you then!"

Shinji Matou held back his laughter as he watched Rin Tohsaka earnestly threaten him, but he shook his head and didn't say much.

"What's with that expression of yours?" Rin stared at his face like an angered kitten.

His calm and composed look made her feel as if he had control over her every move.

"nothing."

"You don't look trustworthy at all. Let's make a deal first. I will come here to visit Sakura when I have time. If she cries to me, I will definitely not let you go."

It was still a child's threat, and Rin Tohsaka knew very well that she couldn't see her sister anymore after Sakura was adopted into the Matou family to avoid any suspicion.

"No problem."

"But she seems a little shy, why don't you introduce her to me." Matou Shinji suggested.

If he wanted to take the initiative to contact Matou Sakura, Tohsaka Rin, who was her sister, would be the perfect intermediary.

The existence of Rin would quickly reduce Sakura's level of vigilance towards him.

It was very necessary to establish a good relationship with Sakura in a short period of time, otherwise, Matou Shinji would not be able to find a reason to protect her from Matou Zouken.

"I know, it is indeed necessary. You wait here, I will call her right away." Tohsaka Rin trotted away resolutely, and within a moment, she pulled her sister over.

Sakura Matou still had the same appearance.

Well..if Rin inherited her father's personality, Sakura was a spitting image of her mother—gentle and delicate.

Her watery eyes gazed at the boy who was about to become her brother, hesitating and not daring to approach.

Rin introduced them openly, "Sakura, from now on, he's your brother. If he bullies you, you should tell me immediately, and I'll teach him a lesson."

Shinji Matou also smiled gently,

"My name is Shinji Matou.

Please give me your advice in the future."

Sakura blushed and nervously intertwined her fingers. In a soft, sweet voice, she said, "I'm Sakura. Nice to meet you."

After saying that, a layer of mist brewed in her eyes, which quickly turned into tears. Next to her, Tohsaka Rin panicked and said, "What's wrong, Sakura? Are you feeling uncomfortable somewhere?"

"It's not... It's not that. I just feel relieved. It's wonderful to have new family members who are just as gentle as my sister." Sakura Matou wiped away her tears and forced a strained smile.

"Sakura..."

Rin Tohsaka fell silent, and Sakura's smile only deepened her sense of guilt.

She was supposed to be the older sister, the one who should protect her younger sibling, yet it was Sakura who had to leave her own family and enter a completely unfamiliar environment just because of her.

She embraced her sister, burying her face in Sakura's silky hair, soothingly saying, "It's okay; I've always been here, and I will protect you."

"Elder sister..."

Matou Shinji looked at the scene of deep love between sisters with a speechless expression. After the two separated, he said with a funny smile: "From now on, I am Sakura's brother. How about calling me brother now?"

Matou Sakura was stunned, her little face was filled with shyness, she opened her little mouth but was too shy to speak.

"Wait! The adults haven't decided yet! What did you say without permission!" Tohsaka Rin was irritated.

The protective mother glared at Matou Shinji with a high and fierce tone.

In fact, the Matou family had even prepared her room, and today was just a ceremony.

"Sister." Matou Sakura pulled her sleeve and shook her head.

The latter hesitated to speak and mumbled helplessly: "I know, I know it's not okay, really..."

Sakura blushed but, in the end, summoned the courage to step forward, politely bowing to Shinji Matou, saying, "Big Brother."

Hearing Sakura's address, Rin Tohsaka couldn't help but feel a bit uncomfortable, but she resigned herself to the situation.

Shinji Matou had a feeling of playing house with the children, feeling relaxed and carefree.

He smiled and responded, "Sure, no need to be so formal. Just call me 'brother.'"

"Then... Brother," Sakura said shyly, her face turning red, and she spoke in a soft, gentle tone.

As expected..children are indeed easy to get along with, and there was no need for suspicion.

"Ah! Ah! Ah! You really know how to make people angry!" Next to them, Rin Tohsaka was exasperated, shaking her head vigorously.

She angrily grabbed Shinji's collar and shouted, "I just want to beat you up right now!"

In a not-so-nice way, Miss Tohsaka now understood what it felt like to be teased by someone else, especially when Sakura called Shinji Matou "brother."

Seeing her sister Rin Tohsaka's overreacting response, Sakura couldn't help but laugh.

"Then I will complain to your mother."

Matou Shinji shrugged and used his child's trump card to complain.

After Tohsaka Rin let go of his right hand, he calmly adjusted his collar.

The little girl was frustrated and said to herself: "Despicable guy."
