Rin walked to a boy no older than five. Facing a five-year-old child, Rin's eyes showed a deep, ingrained disgust.
Matou Shinji was the son of Kakuno Matou, whom Rin had just tortured to death; the only grandson of Matou Zouken; and the only heir of the Matou Family of Rin's generation.
In the original story, when Sakura was first adopted by the Matou Family and suffered abuse, he was the only one in the Matou Family who offered Sakura a bit of warmth. However, this tenderness was not love, but rather because he felt a sense of superiority over Sakura as the family's direct descendant, and offered her a bit of concern, similar to how one might treat a pet dog.
But even so, for Sakura, who was trapped in hell, this small amount of concern was warm enough, becoming the only glimmer of light she could see, preventing her from falling into utter despair.
And when he learned, through an incident deliberately orchestrated by Matou Zouken, that Sakura was the true heir to the Matou Family's magecraft, Matou Shinji descended into madness. Jealousy and resentment, he unleashed all his negative emotions on Sakura, becoming Matou Zouken's perfect accomplice.
He completely pushed Sakura into the abyss of despair.
In the original plot's UBW route, which is Rin's route, a particularly ironic scene occurs: Matou Shinji repeatedly made lewd and disrespectful advances towards Rin, yet the Rin in the story ignored and endured them again and again, never pursuing the matter. In the end, she even risked her life to rescue Matou Shinji from the Black Holy Grail.
Do you not know that the one you risked your life to save is the very person who pushed your sister into the abyss?!
Therefore, Rin's favorite route in her previous life was actually the Heavens Feel (HF) route, which many considered the most heartbreaking and darkest. Rather than heartbreaking, it was more about exposing all the darkness to the light. If darkness is not exposed, it can never be illuminated!
And the Rin in the HF route was also her most satisfying version: clear-headed, calm, decisive, and resolute. At the very last moment, she still put down the jewel sword, allowing Sakura to pierce her body just to embrace her sister. The unspoken words of ten years awakened Sakura's consciousness, finally resolving the crisis.
Therefore, even though Matou Shinji was only five years old at this moment, Rin would not show him the slightest bit of compassion or pity. He was just another bug; why wait for him to grow up to crush him? If he's rotten from the root, can you still expect him to turn good!?
Her unexhausted left hand grabbed the collar of Matou Shinji, who was crawling and trembling on the ground, lifting him entirely. She met his gaze through her faceless mask. "Where is your grandfather's room?"
However, Matou Shinji, overly frightened, couldn't understand anything Rin said. After being lifted by Rin, he just kept struggling and shouting: "No! Don't kill me! Don't hit me! No! ..."
"Coward!" Rin, who was already gnashing her teeth in hatred for Matou Shinji, immediately surged with anger. She lifted him as high as she could, then threw Matou Shinji violently to the ground like a rat!
"Wham!"
Still not appeased, Rin followed up with a front kick to Matou Shinji's face. Matou Shinji slid five meters across the ground, kicked by Rin.
Before acting, Rin didn't forget to use her remaining magic to reinforce his endurance. If he couldn't take it and she accidentally crushed him before getting the information she wanted, searching the entire Matou mansion alone would be a huge waste of time.
Rin walked over and once again picked up Matou Shinji, who was already bruised and swollen, his neck twisted to the side and unable to return. She said, "I'll ask you one more time, where is Matou Zouken's room? If your next answer is still irrelevant, you can go join your father in filial piety!"
Matou Shinji, whose face was too swollen to speak after Rin's kick, finally understood Rin's words. "Over, over there." He said, pointing towards the depths of the corridor.
Rin put Matou Shinji down, grabbed him by the collar, and dragged him like a dead dog towards the depths of the corridor.
After walking five meters, Rin felt a jolt to her mind, her body's center of gravity unsteady, forcing her to lean on the corridor wall with her right hand.
Her overdrawn mind was nearing its limit; she had to act quickly, otherwise, the consequences would be unimaginable... And Rin's unusual state was, of course, noticed by Matou Shinji. He glanced sideways and saw Rin's weak appearance, leaning on the wall to stand steady, and even the hand gripping his collar had loosened slightly. He concluded that this person was out of strength, and it was a good opportunity to break free!
However, while Rin's mind was indeed overdrawn, and her excessively depleted mental state caused her to periodically experience mental dazes and decreased control over her body, even though she had consumed too much magic due to anger earlier, physically, at most, her right hand was temporarily exhausted from overuse.
So when she felt a struggling force from the collar in her left hand, Rin instantly tightened her grip and lifted him. Matou Shinji thrashed in mid-air like a rabid dog having a fit.
"Let go of me! Let go of me! You demon! You killed my dad, Grandpa won't let you get away with this..."
When Rin heard Matou Shinji shout the words "Grandpa," her eyes instantly shot out a murderous glint.
I don't need your grandfather to let me go; I won't let your grandfather go either. It's a pity I'm not his match right now. How I wish I could kill both you and that beastly grandfather of yours!
Her left hand, gripping Matou Shinji, swung in a semicircle like a slung shot, directly throwing Matou Shinji into the wall, creating cracks. Then, Rin released him and, before he could land, delivered another front kick! This time, he flew back thirty meters.
Matou Shinji, whose waist was directly broken by Rin's kick, became completely motionless. The violent impact on his internal organs left him without even the strength to cry out in pain; he could only curl up on the ground, eyes wide.
This time, Rin walked directly over, grabbed Matou Shinji by one ankle, and continued walking forward without a word, dragging him.
"Bang!" The solid wood door was directly kicked into splinters by Tohsaka Rin, who then dragged the limp Matou Shinji into Matou Zouken's room.
It was very simple and desolate, a small room in a corner of the villa where he lived alone. In the center was a small round table with four round stools around it. Several ancient paintings hung on two walls, and a few antiques were displayed on a collection shelf.
It was a room that fit the style of an ordinary elderly person, but unfortunately, it was only a facade.
Tohsaka Rin released Matou Shinji, stood in place, and forced herself to concentrate. After several attempts with her right thumb and middle finger, she finally released a detection spell that she usually cast with ease.
It's here!
Tohsaka Rin pushed aside the table and chairs, then lifted a three-meter square section of the floor, revealing a staircase leading into endless darkness under the light.
A chilling, damp, and putrid smell wafted up from below before anyone had even stepped in. Tohsaka Rin let out a cold laugh, grabbed Matou Shinji by his collar, and threw him into the passage.
"Thump, thump, thump." After confirming the echo of him landing had ceased, Tohsaka Rin casually picked up a lantern and walked down.
It wasn't that Tohsaka Rin didn't want to use a lighting spell; firstly, she currently had no energy to cast spells, and secondly, due to the Finale Magic Power, Tohsaka Rin's lighting spells were completely at the level of a flare. While they might be very useful in combat, they were quite impractical for daily life.
Sniffing the eerie, damp, and putrid air, Tohsaka Rin stepped down the stone steps to the bottom of the secret room. What greeted her eyes was a massive worm pit, completely filled with slimy, boneless, soft-bodied worms.
Engraving Worms!
Seeing with her own eyes those disgusting worms that had burrowed into Sakura's body and defiled her purity, Tohsaka Rin was so furious that her teeth ached and bled. Unfortunately, she was currently unable to cast offensive spells to destroy them.
Turning to look at Matou Shinji, who was sprawled limply to one side, Tohsaka Rin gave a cold laugh and kicked him into the worm pit.
Watching Matou Shinji disappear, submerged in the tide of worms, Tohsaka Rin finally felt a slight sense of satisfaction. She bypassed the worm pit from the side and proceeded to other rooms deeper within the secret chamber.
The Matou Family was a Magician family known for their mastery of familiars, primarily insects. Therefore, along the way, Tohsaka Rin saw various insects cultivated in different breeding facilities.
Blade-winged worms, pincer-jawed worms, fireproof worms, poisonous leeches… It must be said that Matou magic was truly disgusting in all its forms, which was likely why it faced the crisis of being cut off.
After passing all the worm rooms, Tohsaka Rin walked directly into the innermost empty stone chamber. On the stone wall directly opposite, a red mark composed of three intertwining horns was imprinted!
"command spells!"
