Harada Sanosuke, 23. Captain of the 10th division. He's very good with a spear and the person you want defending your back while you escape. Harada is an honest man, chivalrous, kind, compassionate, but he's got a short temper. He dreams one day to have a wife and kids, which is why he works to keep the peace in Kyoto, protect the women and children. But he does have a love of fighting, which gets him in trouble, mostly with Nagakura and Heisuke. He also is usually the one to break up the fights between Nagakura and Heisuke...

Harada is actually popular with women, not that he goes after them, they tend to come to him, which is why Nagakura complains about him being popular with them. Harada literally goes to Shimabara for sake, which he loves, most of the time anyway. He can usually tell when something is wrong with his friends and will ask about it. He can also be flirty at times. Otherwise, he has beliefs that men should protect women and he doesn't try to find excuses for his actions. He respects his opponents no matter who it is. 

His voice is smooth, adult, mature, not that quick of a talker, a little aloof, but is capable of yelling loudly. Zelos from Tales of Symphonia is a voice example that can be looked at.
