Shintarou Midorima, a former Teiko Junior High vice-captain and member of the Generation of Miracles, stands 195 cm tall with dark green hair, light green eyes, and black-framed glasses. He meticulously maintains his left (shooting) hand through bandaging and nail-filing for optimal performance. A staunch believer in horoscopes and blood type compatibility, he carries daily "lucky items" like stuffed animals or potted plants. His philosophy is encapsulated in the motto "Man proposes, God disposes."
As Teiko's vice-captain, Midorima regularly played shogi against Akashi without securing a win. Unlike teammates who skipped practice as their talents surged, he adhered to rigorous training discipline, refraining from point-scoring bets to prioritize team roles. Midorima and Kuroko were the first to detect Akashi's shifting personality, collaborating privately to understand it. Post-graduation, he and the Miracles pledged to determine the strongest through high school competition.
At Shutoku High, wearing jersey number 6 as shooting guard, Midorima initially displays reserved, aloof behavior, struggling with camaraderie and appearing arrogant. Teammate Takao Kazunari persistently breaks through this exterior, forging a partnership despite Midorima's resistance. Takao labels him "tsundere" for offering help while denying it—advising Kagami on aerial techniques or prompting Kuroko to develop the Vanishing Drive through criticism. Midorima openly criticizes Kuroko's choice of Seirin, deeming it incapable of utilizing his abilities.
Midorima's basketball prowess centers on limitless shooting range and flawless accuracy. His signature "High Projectile Three" features an exceptionally high arc and can be executed from anywhere beyond the three-point line, including half-court or full-court. Requiring precise form, this unavoidable shot psychologically demoralizes opponents. Defensively, he demonstrates remarkable speed and timing, blocking Kagami's dunk during training. His shooting reliability stems from intense conditioning; before the Winter Cup rematch against Seirin, he enhanced endurance specifically to outlast Kagami's jumping ability.
Significant growth occurs during the Winter Cup after Seirin defeats Shutoku in the Interhigh preliminaries. Midorima discards his solitary approach, actively collaborating with teammates and displaying uncharacteristic enjoyment. This culminates in the "Sky Direct Three Point Shot," a coordinated mid-air pass play with Takao designed to counter Akashi's Emperor Eye, demanding absolute trust and marking a fundamental shift from self-reliance. In Shutoku's semi-final against Rakuzan, he openly defies Akashi, vowing to "teach him defeat" while scoring a mid-court shot.
In "Last Game," Midorima joins Team Vorpal Swords with other Miracles and Kagami to confront Team Jabberwock after their disrespect toward Japanese basketball. He participates in team strategies, executing a refined Sky Direct Three by receiving passes from Akashi, demonstrating adaptability. Following Vorpal Swords' victory, Midorima declares his intent to pursue the NBA alongside Aomine and Kagami, acknowledging their shared passion. This professional ambition marks his final evolution from isolated perfectionist to team-oriented athlete with long-term goals.
