The blue, curly, seaweed-like hair made him look so much like the Second Young Master.
And he should; this decadent uncle, who looked very much like the Second Young Master and clearly suffered from excessive drinking and debauchery, was the Second Young Master's father, Kariya Matou.
In terms of Magician aptitude, he was inferior to his younger brother, Matou Kariya, but because Kariya insisted on refusing to inherit the magical path and left, Kakuno reluctantly inherited the position of head of the Matou Family.
However, for him, it wasn't a disaster; Matou Zouken, who had already given up on his talent, taught him nothing, at most only letting him handle miscellaneous tasks of an assistant level.
And for him, whether it was being a titular leader or having an aversion to the magical path, as long as it meant gaining the Matou Family's assets and a carefree life, it was not a bad deal.
Although this was his own feeling, he was still tormented by pressure, indulging in a life of debauchery day after day.
To put it bluntly, aside from Kariya, the Matou Family members were either inhumane perverts or utterly useless scum.
If history had followed its course, Sakura should have been his adopted daughter.
It's likely that he would have been among those who abused Sakura...
"What's going on! What's going on! What in the world is going on!? And who are you in the yard!? Don't you know where this is!? Ah..."
He was completely like a helpless stray dog, barking hysterically at his surroundings in a panic to cover his fear.
Just thinking that Sakura would be handed over to such scum... Ugh...
Rin clutched her chest, retching dryly, unable to bear thinking further.
Her lovely, gentle sister, her treasure, how could she allow her to be with such a group of scum!
For such a waste, even a glance from him at Sakura would be an unbearable defilement!
An indescribable, unnamed fire suddenly surged in her heart, like a prairie fire, completely unstoppable!
Thousands of bolts of lightning struck her heart, and her rage burned through the nine heavens!
The more she knew about the future, the harder it was to suppress the anger in her heart.
In the past, seeing Sakura's tragedy through screens, through text, would only make her feel indignant and sympathetic, but there was always an unbridgeable dimensional distance.
But at this moment, Rin was the Rin who had lived intimately with Sakura for three years.
Before stepping into the Matou Family, Rin's heart was only focused on the command spells, for the Fourth Holy Grail War, but upon seeing Kariya Matou's scummy appearance, her goal changed...
Recalling Sakura's smiling face... grabbing her clothes and pestering her to tell her stories about Pleasant Goat... their laughter together in the park... the teddy bear she painstakingly chose for Rin... running to bring her an apple in the morning, only to fall asleep leaning against the bookshelf because she hadn't woken up yet...
"My Sakura, my Sakura, my sister, my only sister! How... how could I hand you over to you scum!!!"
Rin wanted revenge! To avenge Sakura! Rin didn't care if any of it had happened, even if it was in a parallel world, even if it was just in an anime or novel from another world, Rin didn't care about any of that!
How could a sister seeking revenge for her sister consider so much!
The magical power that had been rippling like lake water throughout her body instantly ignited like gasoline, spreading explosively like sky-high blue flames, burning fiercely.
The airflow from the magical power burst open like a storm, sweeping through the Matou residence!
Kariya Matou in the hall was directly blown away by the air current, flipping three times in the air, and plastered against the wall at the end of the hall.
Before he could fall to the ground, a fist enveloped in blue flames directly pinned him to the wall through his abdomen...
Kariya Matou, who still didn't understand what was happening, had his body folded like a cooked shrimp, half of him embedded in the wall.
From his neck to his scalp, blood rushed, making him crimson.
The extreme pain and his compressed lungs made him unable to utter a single word, but the figure, like a demon descended from heaven, began to mutter to himself.
"You can't... your son can't... Emiya Shirou can't... your old man can't either... no one can... any defilement of my sister, whether it's an action or an intention, even a single thought, cannot be forgiven...
Whether it's other timelines, anime, games, manga, or doujinshi! Even if it's all just a baseless dream of mine! You scum! You are all unforgivable!"
Rin, her reason clouded by rage, screamed roars that Kariya Matou couldn't understand at all.
She grabbed Kariya Matou's ankle with one hand and swung him towards a support pillar of the villa!
Before Kariya Matou collided with the pillar, Rin activated her reinforcement magic!
Reinforcement: Endurance!
Under what circumstances can humans truly survive? Pierced through the heart? Lungs ruptured? Shot through the head with a bullet? No, some people have survived even these situations, which shows how exaggerated human endurance is.
What would happen if that exaggerated endurance was strengthened by several hundred times?
The support pillar, designed to bear tons of weight, was snapped in half by Kariya Matou, who Rin swung like a weapon!
"Crack!" Accompanied by a loud snapping sound, the entire villa shook.
"You..."
"Crack!" The second one... His internal organs were already a pulpy mess, he couldn't breathe, and his shattered heart couldn't supply blood to his brain, but he was still alive.
"Splat!" The Kariya Matou in her hand was already as soft as a piece of modeling clay, hitting the third pillar with only a slapping sound.
Rin frowned and cursed softly, "Useless." Then, blue flames flowed from Rin's arm, enveloping Kariya Matou...
"Crack!" The third one... "Crack!" The fourth one...
By the time she reached the fifth load-bearing pillar, Rin found her arm had lost all strength, so she simply flung Kariya Matou onto the pillar, where he stuck.
She spun around, delivering a side kick like a giant blade cleaving a dragon...
"Crack!"
Then, the blue demonic flames extinguished... Rin collapsed to her knees, her center of gravity shifted back as she sat on her calves to keep herself from falling, her mind in a daze.
What's going on... Because she was too mentally exhausted, her self-control loosened, and her anger flared up uncontrollably at the slightest provocation... Damn it, now her magic power is almost depleted, and after venting her anger, she feels even more tired. Kakuno Matou is just a minor character; there was no need to go that far for him.
Rin struggled to her feet and walked step by step to the side of the not-yet-dead Kakuno Matou. He had completely stopped breathing and his heart had stopped beating, as these organs had already been crushed into a bloody pulp and spewed from his mouth, scattered everywhere. His eyes were a dull, lifeless grey. If it were anyone else, they would surely think he was dead.
But Rin, with her reinforced magic still active, knew that Kakuno Matou was not dead, or rather, not completely dead.
If it were anyone else, she could simply leave him be, but this was the Matou Family. To prevent the old bug from causing any new trouble... Rin originally intended to squat down and finish him off, but unfortunately, her mind was overdrawn, and she couldn't control her body, so she knelt instead. Rin looked down at Kakuno Matou's still bewildered face and couldn't help but murmur an explanation:
"You probably still don't understand what's happening, because you haven't done anything yet. But in other worldlines, everything your Matou Family did to my sister is enough for me to completely wipe out the Matou Family in every world of the multiverse. I can only save my sister in this world, but there are as many worlds as there are fantasies. In these countless worlds, how many sisters cannot be saved? I know this is just a compassionate thought, but I cannot suppress my anger. This anger of a sister avenging her sister, I entrust you to bear it."
Whether she was talking to herself or truly explaining to the bewildered man, Rin had no interest in saying another word. She raised her left hand, which she hadn't used before, and punched Kakuno Matou square in the forehead.
Even without magic, the trained force of her punch was enough to scramble his brain.
"Alright, time for business." Rin's eyes were downcast as she turned to look at a corner of the corridor entrance leading to the guest room, where a trembling figure was huddled... author's Note: If there are fans who can imagine Kakuno Matou as Kinoko Nasu, this is the resentment of us true fans! Not even the person who created the Moon World is exempt!
