The captain of the tenth division of the Shinsengumi. He is skilled with a spear, using it as his weapon of choice instead of the sword.
His character is historically based on the real Harada Sanosuke .
Sanosuke is the tallest among the Captains, standing at 6'1". He has dark amber eyes and auburn hair - worn long in the first season and cut shorter later on. His traditional Japanese wardrobe consists of a modified white kataginu with red trimming, a red bandage-like obi, red hand guards, and a gray hakama. His Western clothing in the second season consists of a white shirt with a black vest and a long black and white sleeveless jacket, lined with the same red of his wafuku, red hand guards of a Western style to match, a white belt to hold his sword, and black trousers and boots. He has a significant scar across his stomach from a failed attempt at honorable suicide, another trait that he shared with his real historical counterpart.
Sanosuke Harada is one of the most cheerful of the Shinsengumi and can usually be found making jokes with Shinpachi and making people smile. He can be quick to anger as seen when a slip of Heisuke's tongue alarms him enough to throw a punch at the younger officer to silence him. But, despite his temper and his tendency to be laidback when he isn't concerned, he is also very friendly and loyal to his comrades. He prefers the spear to the sword, a notable similarity to the historical Harada Sanosuke.
Sanosuke and Shinpachi begin to feel uncomfortable with Kondou's aspirations to become daimyou and eventually leave the Shinsengumi. Near the end, Sanosuke reappears on the battlefield, fighting numerous amounts of Furies, teaming up once again with his rival Shiranui Kyou to defeat Koudou and his Rasetsu army, and is gravely wounded in the ensuing battle. He is last seen having a brief, quiet conversation with Shiranui while leaning against a tree, his hands placed over his wound, and his eyes losing their usual glint. His ultimate fate is left unclear.
