Seta Sōjirō was Shishio Makoto's right hand man and the fastest and strongest member of the Juppongatana, Shishio's militia. He was often with Shishio, but also performs assassinations or functions as a messenger, like when he talked to Kenshin on Shishio's behalf or gathered the Juppongatana for Shishio's attempted takeover of Japan. Sōjirō's nickname, "Sōjirō the Tenken," meaning "Sōjirō the divine sword," is Shishio's recognition of Sōjirō's inherent talent with a sword as if the skill was passed down from heaven.
During his time under Shishio's tutelage and service, Sōjirō seems to regard him as a combination of master, god, and foster father.

Intelligence: Experienced killer with several years of training by Shishio, natural master of Shukuchi and posesses the Tenken, or inherent talent with a sword.
Weaknesses: Carries the pain of his family's deaths with him under the guise of emotionlessness. His repressed emotions can make his swordsmanship “inconsistent,” according to Kenshin, if they re-surface (like during Sōjirō's fight with Kenshin).
- Shukuchi (Reduced Earth): Sōjirō moves at beyond god-like speed, only showing his footsteps crashing into the floor. This also allows him to run on walls. He is also shown to use reduced forms of the technique, naming them (X) steps below shukuchi. Shukuchi is revealed to be the reason why he could keep up with Okubo and kill him in his carriage.
- Shuntensatsu (瞬天殺) (Instant Heaven Kill): This is the only attack Sōjirō named himself. It involves using Batoujutsu combined with the speed of Shukuchi. It is named for its ability to instantly kill its target victim, a process that wouldn't even be painful due to the speed with which the target is dispatched. Sōjirō was supremely confident in its ability to demolish Kenshin, but by combining his god-speed with the Ougi used to defeat Aoshi earlier on (Amakakeru Ryu no Hirameki), Kenshin won the battle.
- Tenken (Divine Sword or Heaven Sword): The name for Sōjirō's sword style given by Shishio. According to Shishio, Sōjirō's sword skill is sent down from the heavens, meaning he is a naturally gifted swordsman. This ability allows Sōjirō to almost perfectly duplicate Battoujutsu.
