Crossover: I Took In a Runaway High School Girl

After leaving Mahiru Shiina's room, Renji Kamisaka immediately headed to the bathroom, letting the cold water cascade over his body. The sensation stung his skin, washing away the lingering warmth and disturbing thoughts. He wasn't so immoral as to be aroused by holding an angel like Mahiru, then rush to seek release with Sayu or Misaki Kamiigusa-senpai. Alright, he did briefly think about it. But not today. After all, he had just displayed his masculinity to the angel, Mahiru Shiina.

More than that, his mind couldn't rest before resolving Toshihiko Takayama's problem. To be honest, this was also the first time Renji Kamisaka had directly encountered the dark side of this world. The evil spirits he had met before didn't count. The appearance of evil spirits was limited, and Miko Yotsuya was special because she had a constitution and position that attracted high-level evil spirits. In most cases, one wouldn't encounter evil spirits that could affect an entire area. The last time the delivery truck broke down, he even suspected it was caused by an evil spirit's magnetic field—otherwise, how could the delivery company's truck return to normal after he expelled the evil spirit?

More malicious than evil spirits were the wicked criminals in this world. Like the illegitimate son of the councilman, Toshihiko Takayama. When he confessed to Mahiru Shiina, he behaved well. After being rejected, he left decisively and didn't bother her. But after that, he hired criminals to bully Mahiru Shiina, and he hid in the corner to take pictures, wanting to use the video to threaten the girl. Judging by his skillful movements, this certainly wasn't the first time.

It was just that his father was a councilman, which allowed him to commit crimes and be forgiven. Currently, Daisuke Kousaka was clearly a detective and had control over the evidence. But Daisuke Kousaka could only swallow his anger and release Toshihiko Takayama for the sake of his family. And regarding that evidence, it wasn't enough to convict Toshihiko Takayama as the main perpetrator or accomplice. He could hire a lawyer to say that the camera wasn't his, but stolen by a criminal. Also, since they didn't succeed, at most they would convict him on charges of attempted rape of a high school girl. For Toshihiko Takayama, it was not painful at all.

Don't expect a person who is inherently evil like this to repent and realize his mistakes. Even detectives couldn't hold him for long. If he committed a crime, his father would cover for him. What else wouldn't he dare to do?

If only he was evil but didn't provoke Renji Kamisaka, Renji Kamisaka wouldn't care. But he had to set his sights on Mahiru Shiina, and Renji Kamisaka couldn't stand it. This person must be removed!

After washing up, Renji Kamisaka didn't greet the others. Instead, he quietly slipped out of Sakurasou Dormitory. He wore a baseball cap and a mask, covering his face tightly, blending into the shadows of the night. He began to stand near the police station, waiting.

An hour passed. Renji's watch showed ten o'clock at night. A luxurious black car slowly drove up and stopped. A middle-aged man in an expensive suit, with slicked-back and greasy hair, got out of the car. From the police station door, Daisuke Kousaka and his team came out to greet him cautiously, a slight tension in the air.

From the conversation of several people, it was not difficult to see that this person was the councilman nurtured by the Takayama Zaibatsu, namely Toshihiko Takayama's behind-the-scenes father, Tomaru Takayama.

Renji Kamisaka wouldn't be foolish enough to show up and hit someone himself. He took out the cat bag—an artifact tied to him, only he could see it. And when manipulating a cat's actions, it was also possible to trigger his own entry skills. This was what Renji Kamisaka had just discovered. In other words, as long as he manipulated wild cats to deliver a series of combo punches to the councilman, this could also trigger the "Yin and Yang Anomaly" entry skill. Today, let the cats put on a show for heaven.

"Ah, Dad, why are you so slow? I'm almost starving to death!" Toshihiko Takayama, who had been released, emerged from the door, glancing arrogantly at Daisuke Kousaka and complaining to Tomaru Takayama.

"Shut up, look at the good you've done!" Tomaru Takayama couldn't help but glare at this useless illegitimate son. Because he was a son born with a silver spoon, he was very loving. He didn't expect that he had developed such a lawless personality. If only his Takayama Zaibatsu didn't have resources in the black and white worlds, and he, as a councilman, didn't often arrange things, this stinking brat would have been shot a long time ago!

"Tch, what does it matter? I stumbled this time, Dad, I don't care, I want that kid to disappear!" Toshihiko insisted, his tone spoiled and cruel. "Besides, didn't I pursue that woman for you?"

Daisuke Kousaka and the others could only pretend not to hear. Officials with higher ranks could trample people to death. He wished Councilman Takayama would step down, but he had resources and background, which he, a mere detective, could not offend.

"Shut up, I'll deal with you when we get back!" Tomaru Takayama pretended to be a strict father, then showed a friendly smile to Daisuke Kousaka and the others. "Sorry, my puppy has a stubborn personality and has caused you trouble. Compensation for this matter will be sent later."

"Don't dare, don't dare, Councilman Takayama should leave quickly. Compensation is not needed. I just hope your son can do fewer evil deeds!" Daisuke Kousaka couldn't help but retort, his tone filled with palpable irritation. He truly couldn't stand the actions of this father and son.

"Dad, look at this guy, a dog, dares to bark indiscriminately, he should be taught a lesson!" Toshihiko Takayama pointed at Daisuke Kousaka, his face red with anger.

Councilman Takayama narrowed his eyes and said to Daisuke Kousaka with a fake smile: "My child is naughty, please don't take it to heart, Detective. He is still young and doesn't understand anything. Please be patient with him." He turned to Daisuke, his smile not reaching his eyes. "We won't disturb your work."

"Dad!" Toshihiko still protested.

"Shut up! Go home!" Tomaru Takayama roared, his voice laced with menace.

Toshihiko Takayama was dragged into the car by two burly bodyguards wearing sunglasses, his body still struggling. As the car door closed, no one noticed that several cats were curled up under the car, and one black cat nimbly darted into the car, taking advantage of a small gap before the door sealed shut.

"Tch! What trash, calling him 'my son', what a bastard!" Daisuke Kousaka spat viciously onto the dark asphalt, his anger overflowing.

The other detectives looked helpless. "Daisuke, can't you be more patient?"

"You'll be unemployed if your rank is demoted!"

"Being unemployed is better than being a dog!" Daisuke retorted, his eyes gleaming with determination.

Renji Kamisaka watched this scene silently from behind his mask, a smirk forming on his lips. Daisuke Kousaka had extraordinary courage, matching his fierce face. Thinking of Toshihiko Takayama's words just now, Renji Kamisaka couldn't help but scoff. Want me to disappear? Then let's see who's faster.

Renji Kamisaka immediately returned to Sakurasou Dormitory, adrenaline still coursing through him. Then, using the cat bag, he took over the body of the black cat inside Tomaru Takayama's car.

[Ding, cat bag successfully linked to cat.]

Opening his eyes again, Renji Kamisaka's perspective had completely changed. He now saw through the eyes of a black cat, hidden in the corner of the luxurious car. At this moment, the dirty black cat suddenly leaped out from the back seat with a piercing "Meow~!"

Cat combo, activate!

[Ding, precision strike triggered!] [Ding, sarcastic skill triggered, accumulating... Target enters poisoned state, HP decreasing.]

"Ah!" Tomaru Takayama screamed, his hand reflexively covering his face. "Where did this wild cat come from! My face... it hurts!"

"Quick, throw it out!" Toshihiko Takayama was equally panicked, waving his hand at the cat.

Councilman Tomaru Takayama and Toshihiko Takayama were Renji Kamisaka's primary targets. Therefore, after a series of swift and brutal combo attacks, both their faces were full of lingering blood marks, deeply scratched. Moreover, with the 'precision hit' skill, every punch and claw of the cat precisely hit their faces, as if possessing a horrifying intelligence.

However, the cat was just a small animal. How could it compare to the two burly bodyguards beside them? It was quickly grabbed by the neck and couldn't move, held firmly by one of the bodyguards.

"How unlucky!" Tomaru Takayama growled, looking at the blood on his hand. "What are you doing? You didn't even notice a cat got in? I have an important meeting tomorrow, how can I show up like this?" As a councilman, he still cared about his image. Now his face was full of bloody scratch marks, and it hurt so much that he had to get a vaccine. If people saw him at tomorrow's meeting, his high image as a councilman would be gone.

The two bodyguards could only bow their heads and apologize, their bodies trembling. They didn't want this either. But because they were wearing sunglasses, and the cat's fur was black, they didn't notice it for a while.

"Ahhh, my handsome face!" Toshihiko Takayama screamed hysterically, his face full of wounds looking grotesque. "Dad, I want that cat... dead!" He looked at the gripped cat with a hateful gaze. "After we get back, tie him to a pole for me. I'll torture him cruelly before burying him alive!"

Renji Kamisaka saw this scene through the cat's eyes and felt a little relieved. This isn't over. This is just the beginning. By stacking sarcastic skill effects on Toshihiko Takayama and Councilman Tomaru Takayama, Renji Kamisaka had completed most of his plan to eliminate the root cause.

Through the cat's vision, he could see clearly. The red health bars above Toshihiko Takayama's and Councilman Tomaru Takayama's heads were slowly shrinking, a sign that their HP was continuously draining. Toshihiko Takayama and Councilman Tomaru Takayama had their faces scratched by the cat, so they had to change their route to the hospital midway.

When they arrived home, it was already 10 PM. Toshihiko Takayama leaned back on the sofa with a sullen face, ordering the bodyguard to tie up the cat. He would deal with that little thing later. Tomaru Takayama, the councilman, looked at his son with displeasure. He couldn't help but scold him.

"Didn't I tell you to pursue the daughter of the Shiina family? Is this how you pursue her?" The gentle councilman was no longer graceful, all that remained was his fierce face, now exacerbated by cat scratches that made him look like a demon from hell.

Toshihiko Takayama was startled, but his anger was no less. "I... I didn't want to either, but that bitch rejected my confession! No woman dares to reject me!"

"Idiot! It seems I shouldn't have brought you home tonight. You can't even handle such a small matter. I should have shot you against the wall back then!" Tomaru snapped, his voice thundering.

Toshihiko Takayama's anger immediately flared upon hearing this. "Yes, did I ask you to give birth to me? If you hadn't left my mother and married a daughter from a big family, would my mother have died?"

"..." Tomaru Takayama's face tightened, his lips pressed shut, overcoming any remaining anger. He sighed, then softened. "Whatever happens, you must be able to win the heart of the Shiina family's daughter. Do you know? The power behind the Shiina family can rival the Shinomiya family!"

"Hmph, I don't need you to remind me!" Toshihiko Takayama snorted coldly, revealing a wicked smile, despite the pain on his face.

However, at this moment, several more cats suddenly leaped out from behind the furniture, from unexpected crevices. They launched an even more brutal series of cat attacks on the two of them.

"Ahhh! It hurts!"

"How can there be more cats? Bodyguards!"

"Where did you all go?"

Toshihiko Takayama and Tomaru Takayama frantically dodged, screaming, but their newly bandaged faces were scratched again, becoming even more disheveled and bloody. At the same time, both suddenly felt their bodies weaken and fell to the ground, as if all their strength had been drained.

When the bodyguards finally arrived, they all screamed in terror, their eyes wide with horror.

"Ghost... ghost!"

"There are ghosts!"

Before their widened eyes, Toshihiko Takayama's and Tomaru Takayama's faces looked grotesque, and their bodies disintegrated inch by inch, as if fading into dust. A cold gust of wind blew through the room, and they vanished like smoke. Aside from a puddle of blood on the ground, nothing remained. All of this was recorded by unblinking surveillance cameras.

After completing his act of upholding justice, the cats immediately fled from the window, along with the black cat that had been tied up. In this wave, Renji Kamisaka lost nothing. The Takayama father and son paid the price of their lives for their actions.

The next day.

Daisuke Kousaka arrived at the scene with his team, the air in the house feeling cold and heavy. After watching the surveillance footage and questioning the mentally disturbed bodyguards for a while, they all looked at each other, not knowing what to say. The footage was too horrific, too absurd to comprehend.

Daisuke Kousaka suddenly let out a small laugh, a bitter yet relieved sound. "Indeed, heaven has eyes." He ordered, "Come on, let's pull the team. As for the investigation results, just submit this video." He looked forward to the arrival of a truly dedicated councilman—a small hope amidst the corruption.

When the sky wants to rain, a girl wants to marry. The deaths of the Takayama father and son did not have any significant direct impact. The video might shock high-ranking officials, perhaps even cause a little chaos and disbelief. But it also made some people cautious, and they would carefully consider the consequences before doing anything bad.

Finally, Daisuke Kousaka's mission report was: The Takayama father and son used the power of the councilman to commit many evil deeds, which led to them being possessed by cats by some kind of supernatural force, launching revenge, and finally leaving no bones.

Tomaru Takayama was dead. When a wall collapses, everyone pushes it down. Several cases of Toshihiko Takayama coercing young girls, leading to suicide, also resurfaced and were exposed by Daisuke Kousaka. For a while, everyone condemned the behavior of the Takayama father and son, demanding justice that they had never received before. For this reason, the Prime Minister specifically established an inspector position to review the behavior of council members in various regions, a small step towards change.

Morning greeted Sakurasou Dormitory with soft light and the aroma of breakfast. Mahiru Shiina, who was preparing breakfast, was stunned when she saw the news on TV. Her eyes widened in disbelief. Toshihiko Takayama, including his father, a councilman, were dead? It was said that their improper behavior triggered supernatural phenomena? She immediately checked her phone, and there were even some leaked surveillance videos showing absurd scenes.

Others might not know, but Mahiru Shiina clearly knew that all of this had something to do with Renji Kamisaka. So, this is the person who said he would solve the manufacturing problem? she thought, a frown appearing on her forehead. This is too strange, right? How did he do it?

Mahiru Shiina felt no sympathy for the Takayama father and son. Her heart was untouched by their fate. She only felt a little sad—Renji Kamisaka had stained his hands with blood for her. How would she repay this kindness? Her mood was complicated, a mix of relief, shock, and a little… attraction.

Renji Kamisaka yawned widely and walked in naturally, as if nothing had happened, sitting on the sofa in the living room. "Good morning, Shiina-san, and Sayu." He greeted, a gentle smile on his lips. "It smells so good. What delicious food did you make this morning?" His expression was natural, as if the events reported in the news had nothing to do with him, no trace of uneasiness or regret.

Mahiru Shiina's mood became even more complicated. How could someone be so… calm?

Sayu Ogiwara enthusiastically answered Renji's question. "Today, Shiina made love noodles."

"It's not love noodles!" Mahiru Shiina blushed and glared at Sayu, yet there was an underlying warmth there.

Renji Kamisaka chuckled, "I'll look forward to it."

After breakfast, Renji Kamisaka lay on the sofa to digest his meal, satisfied. Today was the weekend, so there was no need to go to school. He felt like he could lie down all day.

Since Sayu Ogiwara was rushing to do homework, Mahiru Shiina was idle instead. Hesitantly, she gathered her slender, beautiful legs, then slowly sat down beside Renji on the sofa. She looked at the person resting with closed eyes, the girl's small mouth slightly open, wanting to say something but stopping, words caught in her throat. A meaningful silence enveloped the living room, only Mahiru's heartbeat clearly audible in her ears.
