Description
Keika Kiyotaki is a young woman in her mid-twenties who serves as a central figure in her shogi household. She is the biological daughter of Kousuke Kiyotaki, a high-ranking professional shogi player, and is also the eldest disciple under his tutelage. She has two fellow disciples, the prodigy Yaichi Kuzuryuu and the talented Ginko Sora, who have been a part of the household since they were children. As the oldest, Keika naturally assumed the role of an elder sister, taking on much of the responsibility for caring for her shogi siblings and maintaining the home. Her relationship with Ginko is particularly close, as Keika is one of the few people to whom the reserved Ginko readily opens up.

Keika's journey in shogi is defined by persistent struggle against a looming deadline. She initially learned the game from her father but grew to dislike it and quit as a child. It was only later, around her third year of high school, that she returned to shogi with the serious ambition of becoming a female professional player. Unlike the geniuses around her, such as Yaichi and Ginko, Keika lacks their natural brilliance, which creates a deep sense of pressure and insecurity. At the age of twenty-five, she is a member of the Research Group, an advanced training association, but is in danger of being forced to retire if she cannot achieve a promotion to Class C1 before the age limit.

Her personality is gentle and nurturing, a natural consequence of being the primary maternal figure in the Kiyotaki household after losing her own mother at a young age. She treats Yaichi and Ginko like family, and despite her own struggles, she often prioritizes their well-being. The pressure of her situation, however, frequently weighs on her confidence. Her playing style reflects this internal conflict; she is a diligent and studious player who takes meticulous notes and researches her opponents thoroughly. She has a strong grasp of standard strategies but often struggles to develop her own unique style. In high-pressure matches, she has a tendency to fall back on basic patterns and can freeze up when an opponent deviates from expected lines of play.

Despite these mental blocks, Keika possesses a deep reservoir of determination. A pivotal moment in her development comes when she rediscovers a notebook from her childhood filled with her own imaginative and fearless shogi moves. This encounter with her past self reignites her passion and pushes her to discard her cautious formalities and play with confidence, no longer worrying about the age or rank of her opponent. Her primary motivation becomes answering a question posed by her ten-year-old self: whether she has become a professional. This newfound resolve is tested in a crucial match within the Mainavi Women's Open, a tournament that offers an alternate path to professional status. Her powerful and aggressive performance in this tournament, driven by the desire to prove that hard work is rewarded, becomes a source of inspiration for those around her, particularly Yaichi. Ultimately, her efforts allow her to successfully become a female professional, securing a two-year reprieve from retirement and continuing her shogi career.
