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.
