**Island of Sisterhood**

Part 1

The sun was setting over the isolated island, casting a warm orange glow over the sprawling campus of the all-girls school. The air was filled with the sweet scent of blooming flowers and the sound of laughter and chatter of the students as they made their way to their dormitories. Among the sea of young faces, one girl stood out - Haruka Yoshika, a young adult with a gentle smile and a caring demeanor. She was a part of the unique program where college students, known as "unnies," raised and mentored younger girls, known as "kouhou." Haruka lived with her unnie, Mai Sato, and her other partners, Yuu Tanaka, Ruka Takahashi, and Midori Suzuki, in a cozy little house on the outskirts of the campus. Her days were filled with schoolwork, taking care of her kouhou, Satsuki and Maki, and helping out with household chores. As she walked towards her house, she couldn't help but feel a sense of pride and responsibility being one of the older kouhou. The program, designed by Queen Harumin Karin, aimed to provide a loving and supportive environment for young girls who had lost their parents or were abandoned. The queen, along with her wives, Emiko Yoshika and Kanade, had created a system where these girls could grow and thrive, surrounded by loving unnies and siblings. Haruka's own life was a testament to this system, having been raised by her unnie, Emiko, and later becoming a kouhou to her younger sisters. As she entered her house, she was greeted by the warm smiles of her kouhou, Rin, Keade, Saki, Nozomi, Susuki, and her siblings, who were all busy with their evening routines. Haruka's heart swelled with love and care for these young girls, who had become such an integral part of her life. Just then, her partners, Mai, Yuu, Ruka, and Midori, walked into the room, chatting and laughing together. "Hey, Haruka! How was your day?" Mai asked, concern etched on her face. "We have a fun surprise planned for tonight," she added, winking. Haruka smiled, knowing that with her partners and kouhou by her side, life was full of excitement and joy. Little did she know, however, that this year would bring new challenges and experiences that would change her life forever. As she sat down to have dinner with her family and kouhou, Haruka couldn't help but think about her own life and how she had ended up here. She had grown up in this very program, with her own unnie, Emiko, and had found a sense of purpose and belonging. Now, as she looked around at the smiling faces of her kouhou and partners, she knew that she was exactly where she was meant to be. The evening passed quickly, filled with laughter and stories of the day's adventures. As the night drew to a close, Haruka helped her kouhou with their homework and got them ready for bed. She couldn't help but feel grateful for this life, and for the love and support that surrounded her. Just then, the doorbell rang. It was Aria, Haruka's younger sister, who was also an unnie in the program. She had come to spend the night at their house, as was the custom - the girls switched homes every week, to spend time with both their unnies, Haruka and Aria. Haruka's heart swelled with love as she watched Aria interact with her kouhou and partners, seeing the bond that they shared. As they all settled in for the night, Haruka couldn't help but wonder what the future held for her, her kouhou, and her partners. She knew that the road ahead would be filled with challenges and uncertainties, but with the love and support of her family, she was ready to face whatever came her way. Aria walked in the door and said, "Hey everyone Haruka I'm going to be taking the girls to the beach tomorrow I was thinking we could all go together." Haruka looked at Mai and they both smiled at each other. "That sounds like so much fun," Haruka said. "I was thinking we could pack a lunch and make a day of it," Aria added. The girls all started chattering excitedly about the trip.
