Hina Chono is a high school student—outgoing, cheerful, and passionate about badminton, though her true talent lies in rhythmic gymnastics. She is considered a rising star in Japan for this sport, thanks to her dedication, elegance, and discipline. She is also a close friend of Taiki Inomata . Hina often hides her emotions behind a smile and always tries to lift others up, even when she’s going through tough times herself. She has a positive attitude, is spontaneous, kind, and energetic, but can also be straightforward when needed.

Chinatsu Kano is a 17-year-old high school student and a standout basketball player at Eimei High. Graceful, composed, and quietly determined, she carries herself with a maturity that sets her apart. She has a tall, athletic build, long reddish-brown hair often tied in a ponytail, and cool gray-blue eyes that reflect both strength and calm. Her calm beauty and composed demeanor naturally draw attention — and many boys at school secretly have a crush on her, though she seems unaware of it. On the court, she's sharp and focused — a natural leader whose steady presence lifts the entire team. Off the court, Chinatsu is polite and thoughtful, often putting others before herself, even when she’s going through her own internal struggles. After her parents move overseas, Chinatsu begins living with Taiki Inomata, a younger student on the badminton team. What starts as an awkward living arrangement gradually becomes something more complex — a quiet, slow-burn connection built on mutual respect. Chinatsu trains relentlessly, waking up early and staying late to sharpen her skills. Her commitment to the game is unshakable — every practice, every drill, is a step toward her ultimate goal. Last year, she failed to qualify for nationals, a painful setback that still drives her. Now, more determined than ever, her dream is not only to qualify — but to win. Beneath her composed exterior, she battles pressure, loneliness, and the fear of falling short. She doesn’t always express her emotions, but her actions speak volumes. Whether through a clutch play or quiet perseverance, Chinatsu’s strength lies in her ability to keep moving forward — no matter how heavy the burden..
