Kujiranami Hyōgo is an imposing figure saning taller than any enemy shown before or after in the manga.
During the battle of Toba Fushimi in the Bakumatsu, Kujiranami fought Kenshin, who cut off his right arm. Kujiranami requested that Kenshin kill him since he did not want to live to see an era where wars are fought with guns instead of the swords, absent of skill and soul. However, Kenshin refused to kill Kujiranami, saying that he did not want to kill anymore than he needed to and that Kujiranami should live in the new era. Already feeling that he had been robbed of a warrior's pride and era, being robbed of a warrior's death was the last straw for Kujiranami. Since then he vowed to kill Kenshin for dishonoring him and joined Enishi's Jinchū to get his revenge.
As a one armed warrior he was aought out and eventually joined forces with Enishi. Enishi gives Kujiranami an Armstrong canon to replace his missing arm which Kujiranami uses to blow up the Akabeko and the police chief's home. When first introduced he appears to be a relatively selfless and understanding person. As the story progress and he takes to bearing a cannon as an arm, his nature is later distorted until he reaches the point of insanity. His height also gradually expands, going from a large-but-still-believable height when first seen, to a towering behemoth with a hand the size of normal people on his rampage.
He is taken down by Saitō, arrested, and put in jail, but later goes berserk in his cell and escapes. He gets his upgraded weapon from Enishi, a grenade launcher and goes on a rampage in Tokyo searching for Kenshin.
Yahiko is the only one around to fight Kujiranami at the time and manages to hold him off until Kenshin arrives and cuts off his grenade launcher, which returns his sanity. Afterwards Yahiko manages to convince Kujiranami that his hatred for a fellow samurai is wrong and has done nothing for him except lead him down the wrong path. Moved to tears by Yahiko's words, Kujiranami accepts that he was wrong, apologizes to Kenshin for his crimes and turns himself back into the police
