The mother of Soujirou was a prostitue and had her son with a man who owned a rice distribution company. Not to make a big scene, the man, who had a family already, adopted Soujirou. The whereabouts and happenings of Soujirou's biological parents are unknown after the adoption.

Soujirou's "family" was cruel to him, even if he was only a young boy. They forced him to work day and night, doing hard and nearly impossible tasks. Whenever Soujirou did not complete the job, he would be beaten up mercilessly. After so many beatings, Soujirou lost all emotions except for happiness. Smiling was one thing he could do to show his "family" that they were hurting him no longer.

The life of Soujirou changed when he had met Shishio. Soujirou was transferring rice bags to a shed when he happened to see Shishio murdering policemen before his eyes. Soujirou, not wanting to be killed by Shishio, harbored the hitokiri. During the time spent with Shishio, Soujirou got the idea that the world is nothing but survival of the fittest. With a sword, considered a gift from Shishio, Soujirou killed his "family" when they had found out about his actions of hiding a wanted killer.

Growing up into his teenage years, Soujirou traveled with Shishio, eventually becoming Shishio's right hand in the process. Soujirou grew up to be the most powerful of the Juppon Gatana. His fighting skills grew more powerful with the philosophy taught to him by Shishio. Soujirou is considered the fastest of all fighters in the series. Unlike Kenshin's speed, which cannot be followed by the human eye, Soujirou's speed cannot be seen by the human eye. He is infamously known for murdering Toshimichi Okubo.

At one time, Soujirou and Kenshin were considered equals, that is, until Kenshin mastered the Amakakeru Ryuu no Hirameki. By hitting Soujirou with the succession technique of the Hiten Mitsurugi Ryu, Kenshin was able to show Soujirou that the world is not all a complete struggle for power. Finally, Soujirou admitted defeat at the hands of the rurouni and decided to do the same as Kenshin, make up for all the wrong he has done in the past. Currently, Soujirou is a wanderer as well, slowly gaining back the emotions he locked away as a child. He is searching for something to believe in, rather than following the way Shishio taught him.
