Ryota Kise, a former Teiko Junior High Generation of Miracles member now playing for Kaijo High, stands 189 cm tall with blond hair, golden eyes, and a left ear piercing, leading to a part-time fashion modeling career. His personality blends cheerfulness and intense competitiveness; he is outgoing and respectful towards those he respects, often adding "-cchi" to their names like "Kurokocchi," yet displays arrogance towards those he deems unworthy and harbors a strong aversion to losing. Before basketball, he mastered multiple sports effortlessly but grew apathetic until witnessing Daiki Aomine's skill, motivating him to join Teiko's team.
Kise's primary ability is "Copy," enabling him to instantly replicate any observed basketball technique, frequently enhancing its speed and power. Initially, this skill had limitations: he could not copy moves requiring superior physicality, such as NBA-level techniques, or non-physical abilities like Tetsuya Kuroko's misdirection. He later developed "Perfect Copy," overcoming physical disparities by compensating with his own attributes—for instance, adding power to Shintaro Midorima's full-court shots or combining Atsushi Murasakibara's defense with Seijuro Akashi's Emperor Eye. This ability strains his body, limiting its use to five minutes normally. During the Vorpal Swords' match against Jabberwock in *Last Game*, he simultaneously activated Perfect Copy and the "Zone" state after recalling Kaijo captain Yukio Kasamatsu's words about honoring their seniors' legacy. This combination made him temporarily the strongest player on the court, though it accelerated his physical exhaustion.
Key relationships define his growth. He deeply respects his Teiko mentor Tetsuya Kuroko, persistently seeking his approval despite rejections. His rivalry with Daiki Aomine fueled his initial drive to improve, though he gradually prioritized teamwork over individual victory—exemplified by passing to Kasamatsu during a critical play against Too Academy, contrasting his earlier self-centered style. Interactions with Captain Kasamatsu at Kaijo aided his maturity, prompting him to reduce modeling commitments and focus on basketball after losing to Seirin.
Personal trivia includes his June 18 birthday, Gemini zodiac sign, and blood type A. He dislikes eel due to choking on bones and earthworms for their appearance, excels in English, enjoys karaoke, and can distinguish mineral waters by taste. He has two older sisters who influenced his modeling career.
