Battle Information
Weapon: Though all his weapons are sometimes generalized as katanas, Soujiro used three weapons in the series: an unnamed wakizashi given to him by Shishio the night that his family was about to kill him, the Nagasone Kotetsu was used in his first battle against Kenshin after the defeat of Senkaku and the Kiku Ichimonji Norimune which he used against Kenshin in their final battle.
Technique: In both the manga and the anime, Soujiro's technique has never been named/mentioned. Although his technique is sometimes called Tenbu no Sai Niyoru Ken, this has proven to be false since this phrase was used by Shishio to describe Soujiro's fighting style but not naming it. The phrase was then shortened - thus his nickname "Tenken".
