Reiya Chisaki’s Junior High Backstory (First Year)
Start of a New Chapter: Moving to Japan
Reiya Chisaki’s life in Brazil had been beautiful on the surface but chaotic beneath. Born to a wealthy and influential family, she grew up surrounded by lavish dinners, high society gatherings, and constant expectations to be “perfect.” Her mother, a strict and demanding woman, was obsessed with appearances and molded Reiya into the "ideal daughter" from a young age—piano lessons, etiquette classes, and a carefully curated public image. Her father, while less domineering, was emotionally distant, focused on managing the family business.
Because of her wealth and mixed heritage, Reiya became a target of bullying during elementary school in Brazil. Her classmates mocked her for being "different" and "privileged," assuming her life was perfect because of her family's money. The bullying made her self-conscious and lonely; she kept a bright and bubbly personality on the surface but internalized a deep-seated fear of rejection. Volleyball became her solace. She discovered the sport through her older cousin, who played for a local club, and quickly fell in love with the game. It was the first activity where she felt alive and free from expectations—here, it didn’t matter who her parents were, only what she could do with the ball. She dreamed of becoming a skilled setter, someone who could orchestrate the court and bring out the best in others, just as volleyball brought out the best in her.
At 12 years old, her parents announced their plan to send her to Japan for junior high, primarily so she could “connect with her Japanese roots.” In truth, her parents believed the move would "refine" her in ways that Brazil hadn't. Reiya was nervous but excited. Japan became a symbol of hope—a way to start fresh where no one knew her as the wealthy girl from a toxic home. What she didn’t realize was just how isolating it would feel at first.

Adjusting to Kitagawa Daiichi
Reiya enrolled at Kitagawa Daiichi Junior High, known for its competitive volleyball program. Being new to Japan, she faced challenges that went beyond normal teenage struggles. Her Japanese, while fluent thanks to her mother's rigorous tutoring, had an awkward formality to it, making her feel out of place. Her classmates initially treated her as a curiosity—a rich, half-Brazilian transfer student wasn’t something they saw every day. Some admired her exotic background, but others were distant or even subtly rude, which triggered memories of being bullied.
Despite her determination to stay upbeat, Reiya struggled with loneliness during her first weeks at school. She tried to make friends with her natural enthusiasm, but many classmates either didn’t know how to relate to her or assumed she was “too different” to be worth the effort. To cope, she threw herself into volleyball, hoping the team would be a place where she could finally belong.
Joining the Volleyball Club
Reiya was thrilled to join Kitagawa Daiichi’s volleyball team, which had a reputation for being one of the strongest in the region. She declared herself a setter, confident in her skills but well aware she had a lot to learn. The high-intensity practices pushed her limits in ways she hadn’t experienced before, especially because many of her teammates were incredibly skilled. She felt a mix of inspiration and pressure—this was where she wanted to be, but she worried her cheerful, talkative personality wouldn’t fit into the competitive atmosphere.

Enter: Kageyama Tobio. A naturally quiet and serious boy, Kageyama was nothing like her at first glance. He rarely spoke outside of volleyball and had a laser focus during practices, leading Reiya to mistakenly believe he’d see her as an annoyance. But once they were paired for drills, she was surprised to find that Kageyama treated her with the same bluntness and intensity as everyone else. He didn’t view her as "the foreign transfer student" or "the rich girl." To him, Reiya was just a fellow setter.
For Reiya, that was everything she needed.

Forming a Friendship with Kageyama
Reiya quickly gravitated toward Kageyama, who became her first real friend in Japan. She admired his talent as a setter and often asked for advice, despite his blunt way of explaining things. For his part, Kageyama found her energy refreshing—her enthusiasm balanced his more stoic personality, and she was one of the few people who didn’t pressure him to lead the team (a struggle he would deal with later). Though Kageyama wasn’t one to get close to others easily, Reiya’s persistence and positivity gradually broke through his walls. Soon, they developed an unusual but comfortable dynamic—Kageyama’s straightforwardness helped Reiya temper her insecurities, while Reiya’s excitement reminded Kageyama of the joy of volleyball.
Reiya loved how Kageyama didn’t treat her differently, which was a stark contrast to the way others often handled her wealth or background. She began to open up around him in ways she hadn’t before, even confessing her struggles with being “different” in school. To her surprise, Kageyama simply shrugged and reminded her to focus on volleyball: “If you’re good on the court, nothing else will matter.” Reiya took that advice to heart.
The two often stayed after practice to work on perfecting their sets. Reiya considered him a rival in the best sense of the word—not because she wanted to outshine him, but because his talent motivated her to improve. She even started picking up some of his techniques, like his precision tosses and sharp instincts. Kageyama, meanwhile, appreciated how Reiya’s bubbly personality lightened the mood during tough practices.

Defining Herself on the Team
While Reiya’s connection with Kageyama became a source of stability, earning the trust of the rest of the team took longer. Though her skills as a setter were solid, her style was very different from Kageyama's. While Kageyama excelled at sharp, pinpoint-accurate tosses, Reiya focused on intuition and adaptability, often adding flair to her sets. Her Brazilian volleyball background came through in her style, which some teammates initially saw as "flashy" or "unnecessary." She worked hard to prove that her plays weren’t just for show but rather a reflection of her creative approach to the game.
Reiya’s turning point came during a practice match early in the first term. Paired with players who were struggling to keep up with Kageyama’s fast-paced sets, Reiya took a different approach. She adjusted her tosses to match their individual rhythms, creating opportunities for them to succeed. Her willingness to adapt and her ability to encourage her teammates earned her their respect, and slowly but surely, she became an integral part of the team.

The Growing Internal Conflict
Despite these victories, Reiya’s struggles didn’t completely disappear. Her parents’ expectations weighed heavily on her, even from afar. They constantly reminded her to excel—both academically and socially—calling weekly to critique her performance or her appearance. At school, though she was friendly and outgoing, there was a gnawing fear that her classmates only saw her wealth and background, not her true personality. It wasn’t until much later that Reiya would begin questioning her parents’ toxic control, but the seeds of discomfort were already there.
By the end of her first year, Reiya felt a sense of belonging that she hadn’t experienced before. Though she still carried self-doubt, volleyball gave her purpose, and her friendship with Kageyama grounded her during difficult moments. Despite her challenges, she began to see Japan as more than just a place for a "fresh start"—it was slowly becoming her home.
