Akane Tatchibana, a talented high school basketball player, initially steps away from competitive sports due to overwhelming pressure. Upon entering Kouzu High School, he encounters Hitonari Hiiragi, the sole player who previously commanded his attention on the court. This meeting reignites Akane's passion, leading him to rejoin basketball with the Kouzu club.

He lives with his mother. Akane possesses a bluntly honest personality, often speaking truths others avoid. During crucial game moments, he executes key plays after uttering his distinctive catchphrase, "Atchoo." Concerned about his height, he regularly consumes flavored milk. Despite this, his formidable basketball skills defy height expectations, featuring powerful dunks and advanced dribbling techniques. He plays power forward for Kouzu.

His relationship with Hiiragi evolves from rivalry into a charged alliance. Initial court interactions are strained, especially during an exhibition game against Hyamazaki – a team coached by Hiiragi's father and featuring his older brother. Challenged by a Kouzu senior during that game, Akane and Hiiragi unite, securing victory and forging a powerful partnership. This dynamic fuels the team's progress as they push each other while navigating conflicts born of contrasting approaches to the game.

Beyond Hiiragi, Akane influences others, inspiring senior Yoshiki Yamazaki to actively return to the team after a knee injury. He also interacts with childhood friend Yoshikawa Sumire. Akane maintains intense dedication to basketball, driving Kouzu's pursuit of higher competition. An OVA highlights a key conflict where Hiiragi departs Kouzu for an elite school, culminating in a direct on-court showdown that underscores their interconnected rivalry. Akane's journey reflects perseverance and teamwork, transitioning from avoiding pressure to embracing challenges alongside teammates, contributing significantly to Kouzu's matches and deepening his understanding of basketball excellence.
