Harunobu Nikaidou (二海堂 晴信)Rei's self-proclaimed "best friend" and "lifelong rival". A four dan, he has played with Rei since they were children. Even though he might appear to be healthy, he is in fact in poor health. He is from a good family. He is modeled after actual real-life shogi player Satoshi Murayama.
