Masachika Kouda

As a dedicated shogi mentor, this skilled player played a pivotal role in Rei's early development. Having shared a deep bond of both friendship and intense professional rivalry with Rei's father, he brought a unique competitive spirit to their matches. Beyond the game board, he acted as a surrogate parental figure, nurturing Rei with the same genuine affection and guidance he provided to his own children while teaching him the complexities of shogi.
