Crossover: I Took In a Runaway High School Girl

Back in his room, Renji Kamisaka pulled out several gift boxes. They had been sent by Yumiko Miura and the others. Yuigahama Yui had insisted he open them when he got home, saying there was a surprise. Now was the perfect time to open them and see.

The first box, Renji opened slowly. "This is from Yumiko, right? Oh, it's a popular light novel about a harem adventure in another world." He smiled faintly, imagining a perhaps nervous Yumiko choosing it.

Next, a book with an elegant cover. "This is from Mahiru, a book on scriptwriting?" Renji raised an eyebrow, slightly surprised. It seemed the angel wanted to help him a little because she saw that he had just worked with Senior Misaki. This book wasn't cheap. It cost 300,000 yen. More expensive than Natsume Soseki's "Heart". A faint smile played on Renji's lips, slightly amused by this unexpected gift.

Renji moved on to another box, taking a deep breath as he saw the cover. "I'm here to see Yuigahama-san, uh..." His eyes widened. "A comic with a big-breasted cover? Or a pornographic one?" Renji Kamisaka's face took on a strange expression, a mix of amusement and disbelief. "Yui, are you serious?" Yuigahama-san, are you sure you're not implying something? A flicker of doubt crossed his mind, followed by a faint blush.

Finally, the gift from Ebina Hina. She wouldn't give me a B1 book, would she? Then this isn't a thank-you, but revenge. Renji opened it cautiously. Not bad. It was a fan comic of the novel Yumiko Miura had given him, with a pornographic theme.

"So, why did both you and Yui give me pornographic comics?" Renji Kamisaka complained in his heart, a comical exasperation. Do I look like a pervert? He couldn't wait to meet Yuigahama Yui tomorrow. I gave her this kind of comic book, let's see how you face me tomorrow. A small revenge plan began to form in his mind.

What he didn't know was that Yuigahama Yui was currently rolling around in bed, burying her face in a pillow out of embarrassment, unsure how to face Renji Kamisaka tomorrow. "Wah, Renji's classmate won't think I'm a slut, right, for giving him a pornographic comic..." she mumbled, her voice muffled by the pillow, her heart pounding at the thought of tomorrow's encounter.

Unlike the panicked and sleepless Yuigahama Yui, Hina Ebina, who had also given a pornographic comic, seemed confused. She had originally wanted to bring some personal items, but she didn't expect to be discovered by Yumiko. A plan gone awry, and a little embarrassing for her.

Returning to Renji Kamisaka. He was still very satisfied with the girls' gifts. After all, he had mentioned that he liked light novels and comics when he gave them his introductory fee at the beginning of the school year. They could give him these, which were also nice gifts for him, and chose his favorite items to express their gratitude. That was thoughtful. Yes, actually, as long as it was a gift from a beautiful girl, he would definitely like it. What mattered was not what you gave as a gift, but that the people giving the gifts were all beautiful girls. Renji Kamisaka felt he was still very innocent and easily touched.

After a while, soft, hesitant footsteps were heard in the corridor. It was Shiina Mahiru, who came to Renji Kamisaka's room door cautiously, like a cat wanting to play but hesitant.

"Renji, I'm back." Her voice was soft, almost a whisper, as if afraid of disturbing the night's peace.

"Come in," Renji replied.

As the door opened, the girl looked at him with a nervous and interested expression, her large eyes reflecting the dim light of the room. She did nothing but hold his jacket and lower her head, hiding her slightly flushed face.

"Renji..." Mahiru called again, her voice trembling slightly.

"Come here!" Renji Kamisaka smiled, warmth radiating from his eyes, and waved her closer.

After Mahiru closed the door and approached, Renji Kamisaka immediately took her arm and pulled her into a hug. Shiina Mahiru sat on his lap, her beautiful face blushing even deeper, her own heartbeat pounding in her chest. But Renji Kamisaka made no additional movements. He simply stroked Mahiru's hair gently, the calming scent of bath soap clinging there.

"I think Mahiru definitely has something to tell me, right~?" Renji Kamisaka whispered, his tone gentle and understanding, as if he could read the girl's thoughts.

"Yes, I want to apologize to you." Mahiru nodded gently, her head resting on Renji Kamisaka's shoulder, her voice filled with genuine remorse. "I'm sorry, Renji, I was wrong." She continued, "I asked you to pursue Yumiko on my own initiative with the goal of helping a friend, which was a very wrong action."

"There's nothing wrong with that," Renji Kamisaka cut her off, his voice soothing. "I admire Yumiko, but what I want to tell you is that it's better to be friends with her openly than to hide our relationship and pursue her." A brief pause, Renji's gaze turned serious. "This way, even if it doesn't work out, we can still be friends and don't have to hide our relationship. Think about it, if Yumiko knew you, her best friend, were stirring up animosity and letting me succeed, your friendship wouldn't be able to continue."

Mahiru's task wasn't to hide their relationship and let him pursue Miura, but she didn't know what to do for a while, so this situation formed. And Renji Kamisaka didn't want to hide his feelings for Mahiru, so he revealed everything to Yumiko and formed a sincere friendship. This could be considered an early completion of Mahiru's task, even without her realizing it.

Thinking about this, Renji Kamisaka smiled gently at Mahiru and continued, "Of course, I understand that Mahiru was thinking of me. I'm very happy that Mahiru cares about me, and I also care about you, Mahiru." Renji Kamisaka gently emphasized the word "Mahiru," looking into her eyes. "So, now Mahiru should know what to do in the future, right?"

"Yes." Mahiru smiled sweetly at him and extended her arms to wrap them around Renji Kamisaka's neck, a sign of deep trust. "In the future, it's better if we just forget about it and continue to be friends. I guess with your greedy nature, you probably won't do anything to Yumiko." There was a slight mischievous and teasing tone in her voice.

"Hehe, Mahiru still understands me," Renji Kamisaka chuckled, enjoying Mahiru's warmth in his embrace. "However, compared to what will happen in the future, I want to do bad things to Mahiru now," Renji Kamisaka whispered, his voice deepening, a subtle promise in his tone.

Renji Kamisaka kissed her passionately, his lips sweeping over Mahiru's. The angel behaved so well. This gaze was full of his feelings, and she naturally felt it. He also had to thank her parents for not paying attention to her. Otherwise, he wouldn't have had the chance to win her heart so quickly.

Shiina Mahiru didn't resist his advance, instead, she returned it innocently and shyly. Until Sayu Ogiwara called for dinner, Renji Kamisaka reluctantly released Mahiru. Shiina Mahiru's body was small and soft, and she smelled like fresh soap, an aroma that always calmed him. She was also very cute. Renji Kamisaka felt he couldn't resist such a girl at all.

Mahiru's face was flushed, she covered her face in embarrassment. "I feel stranger and stranger. It's all your fault!" she squeaked softly.

"Yes, yes, it's all my fault," Renji Kamisaka laughed, kissing the top of her head. "I've led Mahiru astray."

"Hmph, it's good you know." She snorted with an adorable, knowing air and stretched her two slender, sweet legs before him, the beauty of her white skin clearly visible. "Help me put on my socks. Look at yourself. Your socks are all messed up."

Renji Kamisaka took a deep breath, picked up the white socks, and held her clear, jade-like feet. His other hand gently put on the white socks. What does it feel like to put socks on your girlfriend? Renji Kamisaka now knew. It felt truly delightful, like the first touch of spring.

Shiina Mahiru blushed as she watched his movements, adjusted her skirt, then walked out of the room with him, their hands intertwined.

After dinner, which transpired in a warm and laughter-filled atmosphere, Shiina Mahiru remembered that she had promised to give him a lap pillow. So she prepared to go to Renji Kamisaka's room.

However, Sayu Ogiwara seemed to have taken the lead. The subtle movements and sounds within Renji Kamisaka's room were clearly audible. Sayu's laughter and whispers made Shiina Mahiru's cheeks burn. Besides being shy, she was also jealous. It seemed that even though she said she didn't mind, she was still jealous. But Mahiru didn't disturb them. At the moment, Sayu was in a sensitive period. Let Renji Kamisaka comfort her. After all, she wasn't ready to give her body to him yet. Yes, actually she wanted to. But there was no opportunity...

It was midnight. The moon shone brightly through the window, illuminating the darkness. Sayu Ogiwara had no strength left. She leaned into Renji Kamisaka's embrace and poked his cheek playfully with her hand.

"Mahiru must be jealous, you'd better go find her," Sayu whispered, her tone slightly amused, a faint smile on her lips.

"Jealousy is normal. If I went with her, I'd be happy, but not only would I be upset, she would be upset too," Renji Kamisaka replied, stroking Sayu's hair, enjoying the warmth of her body.

"Pfft, you two haven't reached the climax yet?" Sayu couldn't help but laugh, her voice crisp in the quiet night. "Why, are you afraid of hurting her? Or do you like Mahiru more than me?" Sayu's tone became a little more serious, demanding an answer.

"~Why do you think that? I like both of you! If you have to decide who's better, then I can only bring you to her side and let you compare for yourselves," Renji Kamisaka retorted, his mischievous smile unseen in the darkness, a cunning diplomatic answer.

Listening to these scoundrel's words, Sayu Ogiwara couldn't help but roll her eyes, yet her lips curled upwards. "You're truly cunning."

"Does Sayu hate me like this?" Renji Kamisaka asked, his tone turning more serious, seeking reassurance.

"No, I like you very much," the girl said, leaning into Renji Kamisaka's arm, hugging him tighter, the warmth of her heart radiating. "Thank you for comforting me. I've become very strong now. In the future, I will also contribute my strength to you and this family." Her eyes shone with determination, a sincere promise. "I won't lose to Mahiru."

Renji Kamisaka smiled and stroked Sayu's hair, "Keep working hard, I'm waiting for the day you return to school." A sincere and loving encouragement. "With me here, what's so scary about school?" Renji Kamisaka said, looking at Sayu. "Sayu just hadn't met a responsible person before. Those things aren't your fault, so don't worry, everything will be fine. I'll be fine."

"Thank you." Sayu Ogiwara was touched, her heart warming, feeling a burden lifted. When her parents and brother didn't trust her, this man chose to trust her, protect her, and comfort her. So, she wanted to do something for him, to repay that kindness.

"I'm going to the bathroom." She found an excuse and left the room, although in reality she wanted to give Renji Kamisaka and Mahiru some alone time.

Then she arrived at Shiina Mahiru's door. "Mahiru, are you sleeping?" Sayu whispered softly, knocking gently.

"Well... not yet..." Mahiru's voice came from inside, slightly muffled and full of cute annoyance, but also a hint of curiosity. How could I sleep if the person I like is having intimate conversations with another girl?

Sayu Ogiwara heard the annoyance in her tone and couldn't help but curve her lips, a small smile on her sweet face. "Renji told you to go now, or he'll get really angry."

"Ah? Now?" Shiina Mahiru opened the door, her face flushed with surprise, her eyes wide as she looked at Sayu.

"Yes, please." Sayu gently pushed her towards the door and gave her an encouraging look, a teasing smile on her lips.

Shiina Mahiru blushed, gritted her teeth, then walked into Renji Kamisaka's room, her heart pounding. Tiptoeing, she climbed onto Renji Kamisaka's bed. He was so warm, the warmth of Renji Kamisaka's body felt so close. That warm feeling seemed to burn her too, igniting something new within her, something she had never felt before.

Renji Kamisaka immediately noticed something strange in his embrace. It didn't feel like Sayu. It wasn't Senior either. He opened the window, letting the moonlight in, and saw the face of the beautiful girl in his arms with the help of the moonlight.

"Mahiru!" Renji Kamisaka exclaimed, surprised, yet there was a tinge of delight in his eyes.

"Alright, you idiot, don't call me out." She covered her cheeks, not daring to look at his face, overwhelmingly embarrassed, yet her lips curved slightly.

However, Renji Kamisaka chuckled, his laughter breaking the silence. "I won't let you go tonight."

"Alright, I won't go tonight," Mahiru replied, her voice bolder, a new determination in it.

"I won't let you sleep either!" Renji Kamisaka teased, hugging her tighter, feeling Mahiru's pulse near him.

Shiina Mahiru gently raised her hands and wrapped them around his neck. "It's all up to you." Her voice was soft and spoiled, truly igniting his spirit, burning with suppressed passion.

Renji Kamisaka was truly crazy. How could the angel be so cute? Her soft, spoiled voice truly ignited his spirit. That skill naturally drew the attention of the crowd.

There was no more hesitation. Renji Kamisaka lowered his head and kissed her lips, a deep, passionate, and irresistible kiss.

The activities in the latter half of the night were so intense, even Sayu in her own room could hear whispers and then, Shiina Mahiru's faint pleas for mercy, vaguely audible. She couldn't help but laugh, a mischievous laugh full of understanding. Who said she would never be tempted?
