Crossover: I Took In a Runaway High School Girl

A soft, fragrant touch beside him quickly roused Renji Kamisaka. He hadn't been in a deep sleep to begin with, his brain already accustomed to a standby mode.

Looking down, he found two figures curled up beside him. Aside from Shiina Mashiro, who had come to "trick" him, there was also Shiina Mahiru. Could this be considered an achievement in uniting the Shiina sisters? Renji smiled faintly. But God knows, he hadn't taught Mashiro anything else. Now she was learning "cheating" on her own, a funny yet slightly worrying thought.

Renji mused, thinking that Kashiwagi Eri, or Eriri, would be coming to test scripts this weekend. It must be Eriri's handiwork, teaching Mashiro such naughty things!

"Ah!"

Somewhere, a certain blonde with twin pigtails sneezed loudly, as if feeling the invisible accusation hurled at her.

Back in the room, Shiina Mahiru opened her beautiful eyes from Renji's arm, the morning sun touching her eyelashes.

"Good morning, Renji." Her voice was as soft as a silk caress.

"Good morning, my angel," Renji replied, lowering his head and kissing her smooth forehead.

Shiina Mahiru smiled sweetly, her smile illuminating the morning. Her eyes fell on Mashiro again, raising her hand and gently but firmly pinching her small face.

"Mashiro, wake up!"

"I'm already awake, cousin, don't think about sleeping!" Mashiro retorted, her voice a little sulky. "Well... morning won't come." Shiina Mashiro opened her eyes dazedly and looked at Mahiru, then buried her cheek in Renji's arm and rubbed it, seeking comfort.

"What are you talking about? Get up!" Shiina Mahiru's way of dealing with Mashiro was to literally drag her up. Holding her hand, she led her back to her room on the third floor, then picked out underwear for her and made her put it on herself. Though Mashiro always protested that her choices weren't cute enough, Shiina Mahiru didn't care.

This cousin looked silly and cute, but she was actually very cunning. She just wanted Renji to help her pick clothes and then seduce Renji. Mahiru now realized what Shiina Mashiro had said about "delicious food in the morning." She couldn't help but glare at Mashiro.

"Going to Renji's place for delicious food, who taught you this?" Mahiru asked, her tone serious.

Shiina Mashiro pouted, "Mahiru is so stingy. She hides and eats secretly by herself and doesn't share with Mashiro."

"Ah! Is this a question of stealing or not?" Mahiru was a little frustrated. "Does this thing also need to be shared?" Shiina Mahiru was a little crazy, seeing Mashiro's innocence twisting everything.

"You haven't explained, who taught you?" Mahiru pressed.

"I learned it by reading comics," Mashiro answered innocently.

"Then you can't do this to other boys," Mahiru taught her earnestly, her tone full of warning.

But Mashiro looked at her strangely. "I'll tell Renji that Mashiro wants to do that to other boys."

"What was I thinking?" Mahiru murmured to herself, feeling her brain exhausted.

"Humph, you think Mashiro is stupid, how could Mashiro want to do that to other people? Renji is the owner, the only one!" In other words, she would only do this to Renji Kamisaka.

Shiina Mahiru covered her face and sighed. Who said Mashiro was cute? This is clearly Shiina Makoto! She chuckled inwardly, that name she often used as a pun. She even used her own words to complain. However, seeing that she knew what she should and shouldn't do, Mahiru felt a little relieved.

After waking up, Renji Kamisaka stared at a letter in a daze. A letter that had appeared out of nowhere. Its contents were as follows:

"The moment of reunion has arrived. As your child bride, I have grown up and will soon come to Sakurasou. Please prepare our wedding room. Respectfully presented by Yuki Kamisaka!"

Renji Kamisaka was a little confused. As a time-traveler, where did he get a child bride? Is Sakurasou also a system welfare arrangement for myself? Also, the signature is "Yuki Kamisaka"? The same last name as mine? Could it be my younger sister? It seemed his standard configuration was to have a younger sister and a house, with both parents already deceased.

Renji wasn't worried about the room. There were still many empty rooms in Sakurasou Dorm. One of them was reserved for Nanami Aoyama. When Nanami moved in, he would complete a task to get more props or skill entries.

Setting the letter aside, Renji Kamisaka walked out of the room. The aroma of breakfast was already wafting. Sayu Ogiwara was already busy in the kitchen, the faint sound of spoons clashing with pans audible. It would take a few days to process her transfer information and documents. After releasing her binds, she seemed to be reborn, becoming lively, cute, and positive, a truly striking change. This was the meaning of saving beautiful girls.

Seeing her bright smile, Renji Kamisaka's mood also became happy.

"Good morning, Mr. Renji!" Sayu greeted cheerfully.

"So why do you have to add Mr.?" Renji asked, raising an eyebrow.

"Because you're too mature, just like my dad, very reliable," Sayu answered, her smile innocent.

Renji Kamisaka saw her cute smile, raised his hand to touch her hair, and said with a smile, "Just call me Renji, you make me sound old."

"Hehe, the food's ready, go and call everyone to eat," Sayu said.

"Alright."

Renji Kamisaka went up to the third floor and called Misaki Kamiigusa, Frieren, and Fern. Regarding Yuko's matter, he had to thank Frieren for her help. Frieren smiled and shook her head, saying "you're welcome." It was rare for this world to have creatures like ghosts, and she was also very interested in them.

Is this an explanation? Both worlds still have similarities. Renji mused. Perhaps, he could create a teleportation array that could go back and forth between the two worlds? After all, there were only two magical underpants. If I went, it would be embarrassing if I couldn't come back.

Frieren had been addicted to instant noodles and cola recently. She also loved staying indoors and playing computer games. Of course, magic was still being learned. The treasure chest in Renji Kamisaka's room occasionally opened magical potions. It just so happened to replenish Frieren's magic. Of course, it wasn't strictly necessary. There were also other magic replenishment methods. But Fern was shy and refused to come again no matter what. Of course, she wouldn't mind if Frieren came with her. But Frieren herself was struggling, so the relationship between Renji Kamisaka and the two mages would stop here for a while. But as long as the two of them were still staying here, it was only a matter of time before they became closer.

That's right. After that night, Frieren never mentioned leaving again.

As for Mai Sakurajima, she hadn't returned yet. But she sent a message to Renji Kamisaka, saying that she would be back tomorrow. She and her mother paid a large sum in damages to terminate the contract with their previous company. Now they were all out of money.

But that wasn't a big deal. Renji Kamisaka had already called Yukinoshita Haruno and asked her to set up a film and television company first, and then he would write the script and let Mai Sakurajima play the lead role.

Yukinoshita Haruno couldn't help but complain. She said she was reaching out for a long time. He spoke one sentence and made his fiancée run around. Truly a boss who exploited his employees.

Renji Kamisaka said that he would compensate her well. As for what kind of compensation? Definitely a sweet date.

The shares in the game company given by Akasaka Ryunosuke were quite beneficial. After all, it was a multinational virtual reality game company. Virtual reality technology could be said to be a world-changing technology. And the crystals he provided created the most favorable conditions for the core of the virtual reality game. At this time, the game had been tested based on the core. If Renji Kamisaka saw the test list, he would see that there was a player named "Kirigaya Kazuto" on it...

However.

What Kayaba Akihiko and the others didn't know was, the development of the virtual reality game would allow the elf crystals provided by Renji Kamisaka to hatch, and ultimately their research results would belong to Renji Kamisaka. A grand plan was unfolding, far beyond their comprehension.
