Mentor and Maternal Figure
Hiroko Seto shared a deep bond with Kousei's mother Saki during their university years, and was the very first person to recognize the extraordinary gift hidden within young Kousei. Yet it was her own encouragement that set him on a path toward a painful and demanding musical upbringing—a fact that has weighed heavily on her conscience ever since. When Kousei tentatively steps back into the world of music, Hiroko embraces the role of guide and guardian without hesitation, drawing on her wealth of performance experience to help him confront his inner shadows and emerge transformed.
