Kobayashi Sadayuki (小林定之; also given as Seijirō 誠次郎) is the figure who bridges the two halves of the transition that Shimoe Hidetarō (下江秀太郎) does not — the Battō-tai (抜刀隊; drawn-sword corps) and the gekken sewakari (撃剣世話掛; police fencing instructors).
An Utsunomiya-domain samurai who received transmission from Chiba Michisaburō (the same Genbukan line as Shimoe), he served in the Keishichō Battō-tai in the Satsuma Rebellion, then became a gekken sewakari, and afterward opened the Shiseikan (至誠館) dōjō at Kikukawa-chō in Honjo, Tokyo (Hokushin Ittō-ryū (北辰一刀流), n.d.).
Hokushin Ittō-ryū sources count him, with Shimoe, Naitō, and Monna, among the shitennō (四天王; “four heavenly kings”) of Chiba Michisaburō’s line (Rekishi to enkaku / jinbutsu-den (歴史と沿革／人物伝), n.d.).
Because he actually fought in the Battō-tai — which Shimoe did not — he is a clear link from the 1877 corps to the 1879 system.
