She has written two novel series, Tondemo Police and Kiss Dakeja Iya, and the manga Shion no Ō.
[3] Hayashiba defeated professional shogi player Kinji Shiihashi [ja] in a 1991 Ginga Tournament [ja] game using the rare Sleeve Rook opening as Black,[4] which made her the first female professional to defeat a male in a tournament game.
However, since she left the JSA instead of retiring via the normal channels, she was not given the title.
